Ore will be grinded in grinding machine. Cylindrical grinding machine as shown below:
The cylinder contains a variety of diameter of crushing media (steel ball, steel bar and gravel). When cylinder rotate around the horizontal axis according to the specified convolution, the crushing media and rock put in the cylinder will rise a certain height with the supporting wall and then out of free fall or roll off the cylinder wall under the functions of centrifugal force and frictional force. The ore grinding is mainly dependent on the impact force came from the falling of the crushing media and the abrasive action from movement.
Ore will be continually sent from the one end of the hollow journal; The products after grinding will be expel from the other hollow axis of cylinder. When wet grinding, ore is flow away. When dry grinding, ore will be taken away by air flow.Henan Hongxing Mining Machinery Co., Ltd is the professional manufacturer of complete sets of mining machinery, for example,cone crusher,vibrating grizzly feeder Welcome all of you to visit our official website.china mobile crushers:http://www.hxjq-crusher.com/10.html
The row of ore method is divided into two kinds: center row ore and grid row ore. Center row ore refers to the crushed products freely overflow from the end of hollow journal. Therefore, the level of the cylinder inverse pulp must be higher than the level of the lowest row of the ore journal. The grinding machine of center row ore is also be called overflow ball mill. Grid row ore refers to the crushed products will be expelled from the hole around the edge of the grid, which is installed in the end of the cylinder. The grinding machine of grid row ore is also referred to as grid ball mill. Except for the above two kinds of method of row ore, another one is surrounding row ore. It is rarely used now because the method of ore discharge is through the surrounding the cylinder.
There are two characteristic about iron resource:
(1) Many lean ore, the reserves of lean ore accounts for almost 80% of the total reserves.
(2) More Symbiotic multi-element composite ore. In addition, the ore body is quite complex. It is troublesome in iron dressing because the upside of some the poor iron ore bed is hematite, but the lower part is magnetite. Iron ore, which was selected by the following procedure such as crushing, grinding, magnetic, flotation and reselection, is the important raw material in steel production enterprise. Features of China’s iron ore and the higher demands of steel industry to iron ore concentrate put forward the new challenges to dressing workers. Crushing machine has more development requirements to processing technology of metallurgical mining, which greatly promotes the further progress of dressing machine.
Beneficiation process should be highly efficient and simple, for example, grasping the development of energy saving set and trying your best to achieve best result through the most suitable processing. In dressing plant, the proportion used in equipment investment of crushing and grinding task, production cost, electricity consumption and steel consumption is the biggest. Consequently, the economic benefit is largely determined by the selection of crushing and grinding set and the quality of operation and management.flotation separator:http://www.hxjq-crusher.com/34.html
The common crushing machine or grinding set used in beneficiation concluding: jaw crusher, impact crusher, ball mill, ladder-shaped type grinding mill, ultrafine grinding mill and vertical grinding mill. Large-scale crushing machine is the key product in Hongxing Company. Among the beneficiation set, jaw crusher is mainly used for the initial crushing of the ore material. Due to the harsh environment of jaw crusher, it is necessary to utilize or strength the constitution and masters the essential maintenance knowledge for improving the efficiency and stability of set. Large jaw crusher consists of frame, eccentric shaft, pulley, flywheel, moving jaw, side guard plate, toggle plate, back seat of the bracket, adjust gap screw, reset spring, fixed jaw plate and activities of jaw and other structure.
Large jaw crusher produced by our company has the following advantages: large crushing ratio, uniform particle size, reliable and convenient, wide range of adjustment, high efficiency, energy saving, low noise and less dust.
Although vibrating screen is not quite important set in sand making production line, it is an indispensible part because it plays a continuous role in sand production line. However, sometimes the vibrating screen cannot start normally. Engineers from Henan Hongxing will introduce the reason why vibrating screen cannot start normally.
Firstly, you'd better check the power. Checking the current situation of the motor, if it is the problem of motor, it will be ok to change the component of motor; because the work assembly line consist of centralized control lines, if some of the component are broken, timely replacement the broken component is necessary. Sometimes the voltage is not stable; ensuring the start voltage is lower than the rated voltage value can be helpful to the normal work of vibrating screen.
The most common thing is vibration exciter fault. Firstly of all, we should learn the working principle of vibrating screen: the screening of material is based on the vibration theory of vibration exciter. When there is something wrong with the vibration exciter, the vibrating screen cannot start normally. The vibration exciter needs to keep excellent lubrication state which not only need professional and high efficiency lubricating grease but also prevents the lubricating grease from thickening, freezing and agglomerating. Otherwise, it would not achieve the proper lubrication functions; so it is very necessary to check the condition of lubrication oil and change the lubrication oil in time.Henan Hongxing Mining Machinery Co., Ltd is the professional manufacturer of complete sets of mining machinery, for example,sand washing plant,flotation machine Welcome all of you to visit our official website.sand washer supplier:http://www.hxjq-crusher.com/16.html
Secondly, liner sieve equipment itself had problems. Because the constant changes of liner vibrating screen’s material supplier, if the maximum feeding material value exceeded the required feeding value, it will be blocked in the surface of screen. When the material accumulation to a certain amount, it will lead the work load of liner vibrating screen to become too large to start. The method to solve this problem is to clean up the material in the surface of the screen and ensure the screen can separate the material smoothly.
With the continuous development in human culture, various industries in various field gradually forms its own unique and develops along with the development of social, economy, science and technology. As the object of labor in the national economic development, mining mineral recourses is the enterprise about the investigation, exploration, mining, metallurgical activities. Of course, mining machinery culture is also one of the culture branches in the forms of art, knowledge, concept of mining culture. As the most critical and decisive factor in the mining industry, mining set is particularly important.
Related enterprises in the mining equipment should and must attach much importance to the formation, development and transformation of mineral culture in order to seize the main contradiction to solve the problem. So far, human being has become the master of the world, but human activity must respect the laws of nature, or they will inevitably be destroyed by nature. Therefore, the development of mining set must respect the objective laws too; otherwise, it will become the victim of its own evil deeds. According to the data, in 2008 national coal production accounted for 1/3, but coal mine accident deaths accounted for 80% of the world; regardless of the small coal mines or large state-owned coal mine, the major reason why the frequent occurrence of accident is that we goes against mining culture laws.
Mining equipment enterprise likewise, in today’s era of knowledge economy, the enterprise seeking future industry lead in the future industry particularly should obey the objective laws, respect the mining culture and adapt to the market changes. If mining culture is the spiritual civilization of enterprise, then the market is the social formation of the material civilization development. Both spiritual civilization and material civilization should be given enough attention to and both of them should be developed equally. Market is the essential factors for the enterprise’s existence, if there is no market, there will all be empty words. In order to win the market, we must learn how to formulate market strategy. Business is war without bullets; you will have to be familiar with the basic information of the opponent in order to win the war. It goes without saying that know yourself is to be quite familiar with your enterprise’s basic condition and capability. Knowing your enemy is not only the understanding of competitors in peer companies and competitor’s consumers. There are two forms of consumer demand: one is the real demand, the other is the potential demand. The reality of demand is the demands of consumers actually feel, the potential demand is not formed in the ideology of consumer but the existence of demand.Henan Hongxing Mining Machinery Co., Ltd is the professional manufacturer of complete sets of mining machinery, for example,jaw breakers,combination crusher Welcome all of you to visit our official website.raw material mill:http://www.china-hxjq.com/p75.html
Any business aiming at succession must change traditional concept and regard market demand as the starting point. If a business without the guiding ideology of mining culture and forward-looking foresee consciousness is only satisfied with the market share in the short term, only focusing on the immediate interests will route to failure abyss. The only way for the development of mining enterprise is to understand and adapt to the mining culture and transfer market concept. ” Survival of the fittest” is the eternal law for survival.

Hammer crusher is widely used in mining, chemical, metallurgy, building materials, electricity and other industries used crushing equipment. Hammer is the main wear parts which has direct impact of the hammer crusher crushing efficiency. The most import part in a hammer crusher is the flat hammer. Some of its advantages are introduced as follows.
Flat hammer shape and fastening methods are closely related and work load. Flat hammer should be designed to meet the reliable, easy handling and improve the utilization of sheet metal flat hammer requirements. Flat hammer is generally made by high chromium cast iron, high manganese steel and other wear-resistant alloy steel. Flat hammer shape a lot, have a long strip, T-shaped, S-shaped, work-shaped, with ax-shaped trough and other shapes, the flat hammer is now generally strip.When hammer crusher is working, the main use of flat hammer blows to the material realization of the role of the collision of materials broken during use, due to various types of sheet material with flat hammer structure for full contact role, so its easy to as the device’s main loss has a great piece of equipment consumes. Consumption is usually flat hammer flat hammer the loose and broken, flat hammer wear and tear on the equipment production is not a greater impact. Flat hammer after breaking loose, it is easy for the rotor, causing damage to counter-attack aircraft, and even break the rotor shaft, the rotor structure, resulting in crusher flat hammer over-consumption.
Flat hammer excessive consumption is usually due to structure of the connection plate bolt and flat hammer flat hammer poor manufacturing quality, routine equipment maintenance not in place. Prolonged use of the flat hammer will produce different degrees of wear, after the flat hammer is too large will have a loose bolt connections in the processing of the bolts, the bolts and nuts to feed the better the bite, the threads of the bolt the manufacture of relatively thin, bolt fastening ability. Flat hammer in the manufacture of board, due to poor manufacturing quality, will lead plates occur within the pores or hollow flat hammer, heat treatment and other aspects of quality can also cause flat hammer down. In the specific production, because of the duration, intensity of work, production of various factors, the board has not been regularly improved flat hammer structure overhaul and maintenance, the same flat hammer is caused by consumption of large direct cause. china impact crusher：http://www.hxjqchina.com/product-list_12.html
Flat hammer to install on board, to strengthen the connection of the fastening bolts, re-create the bolt abrasive, so bolt oval head screw contact surface can be achieved with good contact, the thickness of the bolt thread teeth to keep the required size poor range, to avoid the crusher flat hammer produced by the excessive concentration of stress fracture. In the crusher plate flat hammer on the selection made, the choice of a higher wear resistance of high chromium cast iron multi-plate flat hammer manufacturing. In the crusher after each production equipment inspection and maintenance in a timely manner, the structure of the mounting plate flat hammer to flat hammer on the board and the notch of the bolt hole to clean up sand and burr grinding, making the equipment more closely connected, in the fastening flat hammer on the bolt when the oval head for flat hammering in the process of equipment operation should be checked regularly to the bolt, and bolt and screw point welding to increase the stability of the connection plate flat hammer.

A grinding machine uses an abrasive wheel to final machine precision components to fine tolerances ,it is possible to achieve accuracy down to less than .001mm.There are 3 general types of grinding machine,Internal which machines bores,external which grinds outside diameters.and surface which grinds flat surfaces on components.There are other types of specialized grinding machine like gear/spline grinders etc .
Adopting advanced structure of the similar products in foreign countries, the High-rate Raymond mill is designated on the basis of modification and renovation of large scale Raymond mills. Compared with ball mills, the High-rate Raymond mill has higher efficiency, lower power consumption, and smaller area occupying and smaller lump-sum investment. Due to the centrifugal force, the roller mills grind tightly on the rings. Thus it will not influence the output and granularity of the finished products even when the roller and the ring have wear-out in some degree.
It is designated for processing superfine powder of over 300 noninflammable and nonexplosive materials with Mohs hardness below Grade 8 and water content below 6% in the field of mine ,chemical industry, building materials, such as barite, calcite, potash feldspar, steatite, marble, limestone, dolomite, fluorite, lime, active carclazyte, active carbon, bentonite, kaolin, cement, phosphorus ore, gypsum, glass, manganese ore, titanium ore, copper mine, chrome ore, refractory materials, heat preservation materials, coal coke, coal fines, black, , bone meal, titanium white powder, ,quartz, and so on. The finished products can be adjusted freely from 80 to 325 meshes with max meshes of 600 for some materials.
After many years of practice and improvement, Raymond mill structure is getting perfect day by day. For low consumption, low investment, environment friendly , small occupation area, and more efficient than the traditional mill, it is widely used in the field of metallurgy, building materials, chemical industry and mining to process powder. The raymond mill is used in grinding the non-flammable and non-explosive stuff which has the Moh’s hardness below 7, humidity less than 6%, such as gypsum, talc, calcite, limestone, marble, feldspar, barite, dolomite, granite, kaolin, bentonite, bauxite, iron ore etc., the final products change from 613 micron to 44 micron. Through the function of separator and blower, raymond mill can meet different customers’ demand. mobile impact crusher:http://www.crusher-machine.com/2.html
Structure of Raymond mill:
1.The whole plant is a vertical structure of strong systematic characteristic, so it occupies small area. From crushing of raw material to grinding and packing is an independent production system.
2.Compared with other milling plants, its passing ratio achieves 99%, this is what other mill can not reach;
3.Driving system of main frame adopts airtight gearing and pulley, drives smoothly and operates reliably.
4.Main parts of the whole plant are made from cast and steel of high quality. The techniques is so subtly that insures the durability of whole plant,
5.The electric control system is centralized controlled, so the automaticity is high, no people are needed in the operating room.
Raymond Mill Maintaince:
1. Prior to installation of the equipment, all the people who will be assigned to operate the equipment have to be technically trained to know the principle and rules of operation. Someone should be specially selected and put in charge of the operation.
2. To ensure normal operation of the equipment, a manual containing strict rules and procedures for its operation, maintenance and repair should be well prepared and followed. Tools, replacement parts for maintaining, repairing and lubricating oil and grease must be available for immediate use.
3. After a period of usage, the equipment should be checked, to replace worn-and-torn parts such as rollers, rings and shovels. Be sure to fasten connecting-bolts, nut collars to fix rollers properly. Be sure to lubricate the parts sufficiently.
4. Roller should be replaced after 500-hours use. To check bearing in them and replace broken ones, and then fill enough oil and grease (with oil-pump or grease-gun).

A newest book in searching green China is published. It is a landmark for building green future in China.
The book, Green China: Chinese Insights on Environment and Development which is published by IIED with the Chinese Academy of Social Sciences and edited by James Keeley and Zheng Yisheng – is a collection of translated articles from the China Environment and Development Review. As such, it presents an interesting picture of sand maker not only of the environmental issues facing China, but also (so goes the premise of the book) of how these are discussed within the country itself.
The articles are divided into five categories, making up the five sections of the book: the first introduces the volume and outlines China’s main environmental challenges; the second describes case studies demonstrating approaches to conservation; the third deals with institutions and policies; the fourth considers a number of theoretical issues, and the fifth consists of a single chapter on the development of Chinese environmental NGOs.
A number of important topics are covered, including the fundamental role of institutions and administrative processes in the response to environmental crises, and the question of how to measure the impact of environmental damage on economic development. Another frequent theme is the effect of previous environmental policies, and how poorly planned or executed initiatives have shown themselves counterproductive, at times catastrophically so.
The more descriptive and detailed case studies of conservation from different regions in China are also interesting, and help to illustrate the sheer range of environments under threat. For the most part, the discussion takes place squarely in the context of China’s social and political demand for continued economic development, and it does tend to focus almost exclusively on China itself despite the global nature of the issues covered.
Broadly speaking the book is very accessible, and the English text is clear and consistent. Each chapter is self-contained, and can easily be read on its own without reference to the others. The collected articles do not perhaps provide a balanced or comprehensive overview of the current environmental debate in China, and some topics, such as green GDP accounting, are arguably overrepresented. The chapters also differ in the amount of data and analysis they present, and many of them limit themselves to general description and the statement of arguments, though most remain convincing. screw classifier:http://www.hxjqchina.com/product-list_37.html
sand washing equipment:http://www.china-mills.com/p9.html
In describing the challenges faced by China, several crucially important points are made, one of which is the importance of institutional and legal structures as well as administrative processes in tackling environmental problems. In their chapter on environmental law, Wang Jin and Wang Mingyuan illustrate how China’s legal system has failed due to a consistent preoccupation with economic development in the framing of laws, and a lack of clarity and accountability in implementation and enforcement.
Similarly, Shen Keting’s chapter on relations between central and local government shows how incentives at every level, from taxation structure to performance assessment for civil servants, constantly pushes local government to pursue economic growth over environmental concerns, even to the point of defying central government regulations.
These and other chapters reveal the systemic nature of China’s environmental governance problems, and demonstrate the need for coordinating environmental regulation and integrating it with other legal and administrative priorities. This analysis of the inherent flaws in the system that lead to environmentally detrimental decision-making helps to provide a nuanced view of the problems – one that avoids the pitfall of simplistically and unconstructively shifting the blame onto individual or corporate self-interest.
