In China's infrastructure, crusher is a must. It is widely applied in different projects. We buy them woth the popuse that they help us save energy as well as costs. So when select crushers we need to learn the following factors:
1) total production and the finished grading requirements for the selection of crushing machine type and capacity;
2) the physical properties of materials, such as brittleness, viscosity, moisture content and sediment Maximum feed size, etc.;
3) technical and economic indicators, so that both meet the quality and quantity requirements, easy to operate, reliable, and maximize cost savings; crusher is a great investment you choose, be sure to carefully .
No matter what type of crusher, crushing ratio the greater the discharge worse shape, than in conditions of crushing the small, stone crushing chamber to stay in longer, the more chance of being broken.In addition, the nature of the ore itself is an important consideration, as the ore should wear compression and intensity, humidity difference, so you should be based on the inherent characteristics of the ore crushing equipment to select the appropriate.
Crushers are mainly used for crushing raw materials. The whole crushing production line (sand and gravel production line) includes jaw breaker, stone crusher, vibrating feeder, vibrating screen, etc. Our equipment has a reliable performance, reasonable design, easy operation and high efficiency.
First, the basic process of stone production line introduced first stone from the feeder evenly sent an initial coarse crusher broken, and then produced into a coarse material transported by the belt conveyor to the crusher for further crushing, crushing stone after into the shaker screening of different specifications of the stones, does not meet the size requirements of stone material back into the crusher broken again.
Second, the introduction of stone production line performance of the high degree of automation of stone production line, adjustable discharge particle size, crushing rate, energy saving, large output, producing uniform particle size of gravel, grain shape, suitable for a variety of medium and small roads and bridges construction projects. cement making machine:http://www.hxjq-crusher.com/

Mobile crushing plant, also known as mobile crusher, the mobility of the stone can be crushing, can be seen as a simple stone production line, widely used in railway, highway, construction, water conservancy, metallurgy and other industries. Mobile crushing plant raw materials for processing in accordance with the type, size and material requirements of different products, especially in broken field smaller, more suitable for building waste, construction waste crushing. Mobile crushing plant with coarse crushing,secondary crushing， fine crushing ，and from the customer’s position, to eliminate broken site, crushing environmental barriers to customers as a primary solution. Really provide a cost-effective operation of the project hardware, can greatly expand the concept of crushing operations.
Mobile crusher classification and characteristics:
1 according to the different production process can be divided into track mobile crushing plant and mobile crushing plant and tires.
(1) Track mobile crushing plant features:
The first product launch in the Chinese market is track mobile crushers. Metso to produce Nordberg LT Series mobile crushing plant crushing represented. Crushing more advanced technology and quality, each unit consisting of 25 basic modules, each module has a wealth of optional parts, according to customer special requirements for customers, “tailored.” Track mobile crushers can be used for rocks, ores, asphalt concrete road block, removal of building materials, broken concrete recycling.
Henan Hongxing a prominent mining machinery manufacturer in China,such as Vibrating screen, we provide you with quality mineral processing plant and machinery at an excellent price.
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls. An internal cascading effect reduces the material to a fine powder. Industrial ball mills can operate continuously, fed at one end and discharged at the other end. Large to medium-sized ball mills are mechanically rotated on their axis, but small ones normally consist of a cylindrical capped container that sits on two drive shafts (pulleys and belts are used to transmit rotary motion).
Ball mill energy utilization rate is very low, and the material in grinding distribution has great relations.Nearer to the barrel outer trajectory, the grinding action.While the mill when in actual production, material enters the cylinder body to fall directly the inner layer, the inner layer material through the long time to enter the outer fully milled, and lost a lot of energy.
In order to make the material distributing reasonably, the mill feed part is improved.The old-style right angle feeding change the inclination angle type feeding, so that the material chute angle greater than the angle of repose, smooth material feeding.Reasonable selection feeding spot, causes the material directly into the barrel body outer layer.Finally through the computation and empirical data, determine the feeding device material, filling rate, the rotational speed and the power of mill cylinder body and other related parameters.
To ensure raw material in kiln are fully chemical reaction, which can fully burn completely, cement hydration, produce higher strength.For this purpose, the cement raw meal fineness should be controlled at 0.08 mm square hole screen more than below 10%, cement should be controlled below 8%, pulverized coal should be controlled below 14%. Cement raw meal in limestone, clay and pyrite slag, gypsum, cement and clinker after grinding later can not only to crush, still can make uniformly mixed, in order to assure the quality of cement. ore vibrating feeder:http://www.hxjqchina.com/product-list_14.html
In building materials, metallurgy and chemical production in a large number of crushed to a certain size material such as cement raw materials: limestone, slag, gypsum, etc., concentration field in the ore particles, according to the process requirements, even for fine grinding operation.But the fine grinding operation workload is very large, this hard work, are currently in the mill for.But the efficiency of the mill was very low (15% ~ 30%), so the electric energy consumed more, energy loss is severe, grinding of metal consumption is relatively large.In order to reduce the production cost, must in the understanding of mill these operating characteristics of the premise, according to the material’s properties (hardness, moisture, such as particle size and number) from mill finished the fineness requirements, a reasonable choice of grinding process and fine grinding equipment.But the existing equipment and production line improvement.
Grinding system with open flow and circle flow two.
Open flow during the grinding process, the material once through the mill after the finished product; and the circle flow is material grinding after grading equipment selected products, and the coarse material returning grinding in grinding.Open flow system has the advantages of simple process, less equipment,: investment, simple operation; but the material must reach the product fineness requirements before discharge.Thus the requirements of product is fine, to be finely ground material will crush phenomenon, and in grinding forming a buffer cushion, impairs coarse material further ground, appear even sometimes fine powder ball phenomenon, thereby reducing the grinding effect, increasing the power loss.The circle flow system, can be timely discharged powder, eliminates excessive broken phenomenon, make the mill yield; at the same time product particle size uniformity, and can be used to adjust the method to change the product fineness and grading equipment.

Hongxing Machinery crusher devices mainly conclude jaw crusher, impact crusher, hammer crusher and cone crusher, etc. The coarse aggregate is the crushed aggregate whose grain size is more that 4.75mm, called aggregated rock. The common used aggregates are gravels and pebbles, gravels are the natural rocks or rocks that come through mechanical crushing and screening, whose grain size is over 4.75mm. Pebbles are formed by natural weathering, water flow handling and separation and accumulation and the grain size is also more than 4.75mm.
Hongxing Machinery crusher devices can produce the building pebbles and gravels, which can meet technical requirements of the national standard GB/T 14685-2001 building pebbles and gravels . The choice range of materials is very wide. Ordinary ores can be processed by corresponding processing equipments. Finished products can meet the demands and can used for buildings.
Hongxing Machinery crushers are used for pebble, gravel, rough aggregate processing. Rough aggregate (stone) types: pebble, gravel. Building pebbles and gravels new national standard
makes the types, specification, type and use clear. Both the building pebbles and gravels have three categories, which are used concrete in each level (Less than C30 level or more than C60
level). For alkali aggregate problems of sand and stone, the new standard all makes provisions.
1. Harmful impurities: clay, silt, fine powder, sulfate, sulfide and organic impurity, which are in compliance with regulations.
2. The particle shape and surface features: Gravels have rough surface and air voids and the gravels can bond with the cement in a well condition, but the workability is not so good. Pebbles sand making machine:http://www.hx-china.com/34.html
stone jaw crusher:http://www.hx-china.com/6.html
bond with the cement in a bad condition but the mixture workability is very well. The coarse aggregate whose width and length and height are nearly same is the most suitable material.
Needle-shape or sheet-shape grains under stress are easily broken, which will increase voidage, so that the workability will be bad. for these reasons, the materials selection is very important.
3. Maximum size and particle grading.
If the grain size is increased, the specific surface area will be decreased so the cement quantity can also be decreased. For this reason, the grain size should be large as much as possible. But the size should not be too large for the size is restricted by measurement and reinforcement so the grains with large size (over 40mm) is not so good. Maximum grain size must not be more than 1/4 of the minimum side length of structure section and not be more than 3/4 of the rebar smallest interval.

As we enter the 21st century which is regarded as an age when economy makes breakthrough, but at the same time along with the rapid economic development, environmental pollution has emerged. It brings about increasingly serious threnten day by day. In order to reducing pollution in production, many fields are trying their best to find environmental friendly production way. Hongxing Mining Machinery company, since established, has always been devoted to impact crusher innovation and put emphsis on environment protection.
Most of the firms have considerably enhanced their project recital with project management trainings and kinds of methodologies. This leads in decreasing the level of risk management upto zero. People in such firms have learned the management training and conclude that the projects work more better when the team is smaller and include meticulous connections or communications, regimented kind of project management, and standardized tools of project management.
In cement production process, cement crusher is very important since most of the raw materials will have to be crushed before being used to process cement, such as limestone, clay, iron ore and coal, etc. Limestone is the largest amount of raw material during cement production.

Dust collectors are used in many processes to either recover valuable granular solid or powder from process streams, or to remove granular solid pollutants from exhaust gases prior to venting to the atmosphere. Dust collection is an online process for collecting any process-generated dust from the source point on a continuous basis. Dust collection is a vital process for coal handling, cement fabrication, metal fabrication, mining with equipment such as raymond mill, chemical processing, woodworking, pharmaceutical, recycling and agricultural industries, among many others. The particles released during manufacturing processes are hazardous to both worker and equipment health, quickly leading to a number of problems if particles are not captured by dust collection equipment and filtered from facility air. Dust collection addresses this problem by drawing contaminated air through a filter or separator, trapping harmful particles and releasing cleaner air into the atmosphere or back onto the work floor.
Dust collectors may be of single unit construction, or a collection of devices used to separate particulate matter from the process air. They are often used as an air pollution control device to maintain or improve air quality.
Operating Process of Dust Catcher
The dust-laden air enters the bag filter bustle.
The air is uniformly distributed avoiding channeling.
Initially a coat of material forms on the bags. Subsequently, the coat acts as the filtering medium.
The dust is accumulated on filter elements while the air passes thorough the filter bags from outside to inside.
The accumulated powder is dislodged from the bags by reverse pulse-jet air intermittently.
The dislodged powder falls on bottom cone and is discharged through powder discharge valves. cement making plant:http://www.hx-china.com/37.html
china sand washer:http://www.crusher-machine.com/19.html
The dust free air is sucked by induced draft fan and is exhausted to atmosphere.
Knockers are provided on conical portion especially for sticky/hygroscopic materials.
According to the working principal of industrial dust collectors, they can generally be divided into the following types:
1) Inertial Separators: by using a combination of forces, such as inertial, gravitational, centrifugal force, etc.
2) Fabric Filters: also called baghouses, can achieve more than 99% efficiency for very fine particulates.
3) Electrostatic Precipitators: using electrostatic forces to separate dust particles from exhaust gases
4) Wet Scrubbers: using various types of scrubbing liquid (usually water)
5) Unit Collectors : small and self-contained; it consists of a fan and some form of dust collector, suitable for isolated, portable dust production operations.
Since dust collectors are varied in so many aspects, such as design, effictiveness, operation, maintenance, etc., it is a little bit difficult to choose an appropriate collector. But there are still some factors that we can follow:
1) Particle Size: in minerals processing, dust concentration may range from 0.23-11.44 g/m3, and the particle size may vary from 0.5-100µm
2) Efficiency, location, and allowable emission rate required
3) Airstream Characteristics
4) Dust Origin
5) Dust Disposal Methods

The increasing development of real estate and highway construction makes the crusher industry had a rapid development at the same time. The crusher specification also developed with many varieties. Combination crusher equipment is one of the new type crusher in the market, the sales volume has been rose greatly than last years. The combination crusher equipment market also gradually developed in recent years. Hongxing always make great efforts to produce new type and high quality combination crusher equipment to meet the need of consumers.
One of the new small compound crusher sales market has been gradually developed. The sale volume of small combination crusher has also improved than last years. Here are some factors that affect the production capacity of small combination crusher. 1. Material hardness. Hard material is difficult to be crushed by small combination crusher, so the small size crusher is suitable for brittle and fine material. The hard material can seriously damage the small size combination crusher. 2. The moisture of material. When the material with large moisture content, the material will adhere to the crusher inner wall and cause blocking problem. So inspect the material moisture before feeding material into small combination crusher. 3. The request of final product particle size. Small size combination crusher has large crushing capacity. This small composite crusher is not much requirement for material humidity, it is also suitable for any hard, brittle materials. Now more and more foreigners begin taking notice of our crusher. Also, the crusher industry has the characteristics of environmental-friendly and industry concentration. The manufacturer should hold the development trend of crusher exactly to have a better development.
Vertical Combination crusher
Our crushers are ideally suitable for primary and secondary crushing, with low power consumption and easy maintenance. Every feature of these machines has been carefully designed to provide superior quality and performance. They are widely used for crushing various materials like stone, granite, trap rock, coke, coal, manganese ore, iron ore, emery, fused aluminum, oxide, fused calcium carbide, lime stone, quartzite, alloys, etc. These crushers are recommended by leading consultants in this field and are used by hundreds of customers all over the world. ore beneficiation:http://www.hx-crushers.com/p58.html
The Work Performance
Raw materials are fed from the top of the Combination crusher, and fall into the rotating impeller at a high speed to be crushed. As other materials simultaneously fall around the rotating impeller, the two kinds of materials join together and are crushed by each other. The materials are crushed many times in and around the impeller of the Combination crusher, and are finally discharged from beneath the machine. Via a closed loop, controlled by screening equipment, the product achieves its required final size.
1. The production capacity is big.
2. The crushing ration is high and the power consumption is low.
3. The sealability is good and machine running is stable.
4. The maintenance is simple.
Vertical Combination crusher’s crushing ratio is big. And the biggest crushing ratio can get to the discharging granularity and can be adjusted freely. The plate hammer and lining board wearing cannot have effect on the crushing ratio. There is no sieve bar. The machine cannot be blocked when it crushes the materiel with high humidity and mud percentage. It adopts elastic adjustment structure. If the material which cannot be broken gets into the machine, it can be discharged automatically, so the machine cannot be damaged. The bearing is fixed horizontally and its usage life is long. This machine’s rotor is special. The rotor body hardly wears when the machine crushes the materiel.
