2.The parts need lubricants have efficient lubricant;
3.Ensuring that the screws and the keys are tightened and the security guards are secure and reliable.
4. Checking to find out whether the debris has fallen in the bottom of the high efficiency concentrator or not and whether the discharge opening is blocked or not;
5. Linkage is intact and the valve is flexible;
6. Rake stand is not buried by the ores and the lifting device is flexible.
7. making sure that the electrical parts are sensitive and reliable.
(B) The operation sequence and matters needing attention.
1. If there were problems, the first step is to solve the problem timely.
2. After making sure that there is nothing wrong, the operator can start the machine, the sequence is as following:
(1) After the contact with the upper and lower positions, pressing the motor start button and observing the position of the overload signal device.
(2) After the normal start, falling the rake slowly on the specified location.
(3) Feeding.
3. The start is not allowed when the rake is buried on the ores.
4. After the start, hand touch on the rotating part and move freely guards is not allowed.
5. That wet hands to manipulate electrical facilities is strictly prohibited.
(C) The operation of stopping the machine and the matters need attention
1. The operation sequence is as follows:
(1) Stopping the feeding.
(2) Continuing to discharge the ores until the concentration of the concentrated product is less than 25% and then stopping the concentrator.
(3) Lifting the rake stand.
2. If there is a need to stop the machine because of the accident, lifting the rake stand quickly.
3. Generally, it is not allowed to stop the machine when the high efficiency concentrator is in operation.

flotation cells : http://www.ore-mills.com/flotation-cell.html

Generally, the flotation concentrator and magnetic separator (dry magnetic separator and wet magnetic separator) are suitable for the rougher flotation, cleaning and scavenging.
After the initial sorting, the ores will go through the following procedures such as flotation, re-election or magnetic separation, which will sort part of the gangue or the surrounding rock with water content out, obtaining the products whose ore grade is higher than that of the raw materials. This is called coarse concentrates, which generally cannot reach the quality requirements of concentrate. This process is called roughing service industry.
The procedure that reselecting the rough concentrate to get qualified concentrates is called selection operation. Sometimes, the rough concentrate needs several times of selection to produce the qualified concentrate. The operations in turn are called primary selection, secondary selection….
The general rougher tailings should not be treated as the final tailings to be wasted, which often need the next processing, this job is called scavenging. In order to improve the recovery rate of the metal and sometimes only after repeated scavenging, the final tailings can be obtained.
After the sorting processing, most of the gangue and impurities are removed of the ores and the useful minerals are enriched, which is called concentrate. Concentrate is the final product of the dressing plant, and sometimes it is also called the final concentrate, which is generally used as the raw materials of smelting. The final concentrate whose main component and impurities have reached the national standard can be called qualified concentrate.
After each flotation, the products that are apart from the concentrate and tailings are called middling.
After sorting processing, the main ingredient of the ores has been enriched in the concentrate and some minor components of the ore or other associated metals have been recovered through comprehensive treatment. Therefore, the content of the useful ingredients in the remaining part of the product is very low; this part of the product is called tailings, or the final tailings. Generally tailings dumps are saved in the tailings pond.
The intermediates obtained in the sorting process are known as the middling. The content of the useful ingredients in the middling generally range between that of the concentrate and tailings. In the process of sorting, the middling generally needs returning to the proper place of operations to be processed or being conducted separate processing.

Mixing barrel is used for the ore pulp stirring before the flotation operation to make the ore pulp fully mix with the medicament, creating the conditions for the mineral processing operations.
Mineral mixing barrel is usually used for the stir of slurry in the mining industry, the mechanical stir of the various chemical industries and the stir of burdening of raw material in chemical operations. It is particularly suitable for the mixing stir of the powdered, granular and small piece of materials that have small controllable degree, such as coal, cement, stone, sand, clay, ore and etc.
The maintenance of the mixing barrel is an extremely important regular work, it should be in close coordination with its operation and overhaul.
1. Just like many other mining machinery (sand washer, vibrating feeder) the bearing plays a crucial role in the equipment. The bearing shoulders the entire load of the machine, so the good lubrication of the bearing has great impact on the service life, which directly affects the service life of the machine and the operating rate. Therefore, the lubricants injected must be clean with good sealing. The main oiling parts of the mixing machine include rolling bearings, all gears, live bearing and sliding surface.
2. The newly installed tires are prone to loosen and they must be checked frequently.
3. Paying attention to each part of the machine to ensure that they are working properly.
4. Paying attention to the degree of wear of the wear parts and timely replaces the worn parts.
5. The chassis plane which is used to place the movable equipment should be kept clear so that the live bearing can move on the base when the machine encounters the difficult-broken materials to avoid a serious accident.
6. If the oil temperature of the bearing rises, the operator should immediately stop to find out the reason to eliminate them.
7. When the gear is in operation, if it has impact sound, the operator should immediately stop to check and eliminate.

After the accession to the WTO, the opening up of domestic economic and trade becomes deeper and deeper and the domestic enterprises are seeking development at abroad.In the past, China's mining machinery industry production barely meet the demand of the domestic market, export abroad can not be achieved in the quantity and quality standards. With the development of China's mining machinery industry , manufacturing technology becomes more advanced and the quality of products is constantly improved. That the mining machinery products (dryer machine) in China go out of the country has become a reality. Europe and the United States and other capitalist countries suffer a huge blow from the financial crisis and the economy is in downturn, which makes the market demand for mining machinery (sand waher, impact crushing machine)is not high. China has maintained steady economic development trend. As China has entered the 12th Five-Year Plan stage, the mining machinery industry will usher in a period of rapid development after experienceing a market downturn and many other tests.
For a long time, the technology of foreign enterprises is far advanced than that of domestic mining machinery manufacturing industry and the products produced are only the low-end products, which can not meet the demand for the high-end machinery and equipment of the developed countries in Europe and America. Moreover, the foreign companies have invested and built factories in China,sharing the abundant labor resources and the low wages with Chinese enterprises.Therefore,the price advantage in international market competition of the domestic mining machinery industry is gradually reduced. The product produced by domestic mining machinery manufacturing enterprises would be difficult to win the international market.The another way to go abroad for Chinese enterprises is to purchase the foreign enterprises in recent years. The mergers and acquisitions of foreign enterprises not only can make use of the existing market channels of foreign enterprises to open up market channels for our products to enter the foreign market, but also can integrate advanced manufacturing technology to improve the technology of domestic mining machinery industry.   

With the rapid development of China's coal industry, the demand for coal is further expanded and promote the steady growth of the coal production, which also provides a very favorable environment for the development of coal machinery and creates good condition for the steady development of China's coal machinery industry. The mining machinery industry (including Hongxing Heavy Industries) should enhance the capability of independent innovation of the milling equipment and crusher-the necessary processing equipment for the development of the coal industry to adapt to the requirements of the coal industry equipment.
A lot of coal machinery enterprises, based on their own foundation and advantages, accelerates the construction of high level of equipment manufacturing bases to raise the overall production capacity of enterprises by building new modern factory and conducting technological innovation. The stone production line, sand making line and other production line in Henan Hongxing Heavy Industries are in the lead in the industry. The company constantly enhance the capability of independent innovation, regards the development and innovation of the products as the focus of the work and at the same time the steadily improve the quality of coal machinery and equipment. In harsh operating conditions, the equipment has expressed the productivity and durability, having meet the production indicators of users and the strict requirements of the products. The various crushing equipment, sand washing machine and ball mill and the complete set of production line are an integral part of the coal machinery.
Coal resources has been a top priority of China's national conditions, in recent years, with the continuous introduction of relevant national policies, the market prospects faced by the coal resources has become more optimistic. Faced with such a situation, as the domestic mining machinery manufacturers which continuously devotes itself to the R & D and manufacturing of mining machinery, Henan Hongxing Heavy Industries will continue to further strengthen the capability of independent innovation, improve the level in product design and manufacturing, processing technology, high-strength materials and key quality indicators, truly improving the independent research and development ability. At the same time, it will fully emphasize market development, both the layout of the domestic market and the open up of the overseas markets. Hongxing Heavy Industries will always follow the policy of the country, when providing more high-quality products for the development of the coal industry, it will improve the economic efficiency of enterprises.

Mining machinery industry is the industry, which is an integration of technology, capital and labor. In recent years, with the development of the mining machinery industry in China, the growing market size and increasing efforts to strengthen infrastructure, new higher requirements of mining machinery have been put forward, which not only include the technology and intelligentize, but also consist of energy conservation, consumption reduction and environmental protection. The the traditional mining machinery such as crusher, sand maker can not meet the requirements of the air quality at this stage. The only way to realize long-term sustainable development is technical upgrading and innovation.
1. Improving the technical level. The crusher industry should combine self-development with the introduction and absorption of advanced technology. Compared with the developed countries, the mining machinery (crusher) industry in our country is very immature in terms of technology and equipment performance. High energy consumption and high pollution produced in the backward development way has caused great pressure on the environment. Under the new situation of economic globalization, the mining machinery industry as should also "open horizons", introduce foreign advanced production technology and experience, research and develop high-quality and environmental friendly mining machinery as well as adhere to the independent development and grasp the innovation initiative in their own hands to achieve a new leap of the mining machinery industry in China. The cone crusher produced by Hongxing Heavy Industries has been widely used.
2. Training high-quality personnel. Learned from the current findings, the extreme shortage of human resources in the mining machinery industry in China is a big problem. A lot of the production staff had not received the training of professional theory, just simply try to operate in accordance with the traditional experience, which is an important reason for the backward development of China's mining machinery industry. Judging from the current situation, in order to achieve new development, mining machinery industry should focus on the training of professionals to achieve the integration of knowledge and production.
3. Enhancing the overall level of the industry in terms of internal communication and cooperation. In the highly competitive environment, varying degrees of mutual confidentiality and mutual blockade is beyond reproach, which is necessarily reflect a kind of self-development enterprises. But this phenomenon constrain the enhancement of technical level of the industry as a whole. Therefore, for the development of the industry as a whole, the mining machinery enterprises with higher level should help and drive the enterprises of technological backwardness to achieve the revitalization of the mining machinery industry in China.
In the low-carbon economy, the mining machinery should continue to adopt the new technology to conduct independent innovation, train high-quality personnel, adjust the structure, optimize the industrial chain, realizing sustainable development of the low-carbon economy.

The Development Prospect of Mining Machinery

The Development Prospect of Mining Machinery
In the seminar of equipment manufacturing industry held lately, the experts pointed out that high reliability and energy saving is the inevitable development trend of mining machinery in our country.
Experts believe that the open-pit mining equipment should mainly develop towards the direction of high reliability, energy saving, high-comfort, automatic condition- monitoring and automatic control of the direction, employing the measures of SCR power supply, AC frequency conversion speed, grease lubrication, shock attenuation and pressurization purification, noise elimination of driver’s room and microcomputer automatic control device.
As for hoisting equipment, safety and reliability is the first thing. In its service life and efficiency, it employs the technologies of computer-controlled and dynamic online testing and so on. In the mechanical structure, built-in friction hoist is used. The crushing equipment put hammer double rotor impact crusher into use and the product structure tends to the way of ultrafine grinding. Developing high-tech equipment requires a lot of functional materials. The use of contemporary ultrafine grinding technology has become an important symbol to reflect the level of a national technology.
With regard to Washing equipment, the relevant fields in the world are exploring the sorting requirements to adapt to a wide range of minerals and impurities so that the sorting equipment could be more efficiency and diverse. In some fields, high-efficient concentrator has taken the place of general thickener. The fully automatic filter press with extrusion die, horizontal belt filters and other new filter has developed rapidly. In developed countries, stand-alone automation and full range of mechanical and electrical integration has achieved great development, and jigger, automatic filter press, sedimentation filtration centrifuge, flotation machine, high-efficiency concentrator, swirler and other equipment are applying computer on the full range parameters to achieve automatic control.
It is reported that China's mining machinery equipment has formed relatively complete category with substantial scale and significant level of equipment through the introduction of technology and co-production.

Safe Usage of Mining Equipment

Safe Usage of Mining Equipment
In modern society, with the booming of industrial economy, many countries and regions in the world need to cut a lot of the mountain to accelerate the development of the local economy. How to chisel the mountain? Here, the large-scale mining equipment is indespensable. China is a vast land with abundant resources,where there are many situations to use large mining equipment. At this time the safely use of large mining equipment is very important
Attention should be paied to the safely use of large mining equipment and we should also choose som regular large-scale machinery companies,such as Henan Hongxing Ming Machinery Co.,Ltd. The large-scale mining machinery researched and developed by it has played very importan role for digging the dickite amd chiseling the mountain. The mining equipment of Hongxing Heavy Industries are in use in many areas, promoting the economic development of many countries and regions.
The users should pay attention to the usual maintenance and repair and they have to regularly carry out the necessary inspection and maintenance of large mining equipment. Fpr example, they should conduct safety checks to various parts of the large mining equipment to look up whether their function in opration is normal; regularly check the equipment for wear situation, if there were such kind of parts, they need to replace the worn parts timely. When using lagre-scale mining equipment,if the bearing’s temperature is too high, they should immediately stop using and find out the reason. In addition, the screws of the linkage components of the large mining equipment screws have to be conducted regular check to prevent infestation.
The usual maintenance of large-scale mining equipment is very easy, easy operation and low fuel consumption. But its work environment is very poor so that lubricating oil in the equipment can be easily polluted by the impurities in environment such as dust and solid particles. Therefore, lubricating oil should have good anti-corrosive quality and corrosion resistance. Only in this way, the performance of the lubricating oil in the inclement environmental will not take much changes. Moreover, the users also should associate with large mining equipment companies to communicate and understand the performance and technical characteristics of the machine to facilitate the use of lagre-scale mining equipment in the production.

To promote sales growth with innovation

Hongxing Heavy Industries,to promote sales growth with innovation
The society is seeing great development, which change with each passing day. The trend can not be halted. During this process, upholding and advocating creative spirit to build our own brand is not only the theme, our primary goal, but also the value and concept that we should adhere to.
When the society is developing rapidly, our country does not lessen the input into the railways, highways, airports, and other municipal projects. Therefore, the application of the crushers is not reduced than expectation, instead, to some extent, crushers have been widely used in many aspects, which are the indispensable equipment in constructional projects.
At this time, Henan Hong Xing Heavy Industries tries best to give play to its technical advantages to update their products, expecting to win further approbation.
For a long time, a big problem which troubles the crusher-users is its weight and depletion. Large size and easy-to-wear off lead to a lot of companies would rather put them in a particular plant to make regular maintenance than adopt the type of caterpillar vehicle to make them more portable, which, to a great degree, restrict their flexibility when making mineral operations. Thus, Hong Xing Heavy Industries is studying from others and making research all the time, working hard to research how to make a kind of materials that are light and wearable. As long as new materials and new technologies are worked out, they will increase the number of orders and also promote update.
The facts speak for themselves, in Hong Xing, the research and production pattern of putting energy-saving and new application-exploration as orientation it holds has promoted the growth of sales greatly. In the vision of the future planning, Hong Xing Heavy Industries will adhere to this way and constantly bring new products and more reasonable and comfortable experience for the users, which will make her have one place in the fierece competition.
