Modern crusher had been created after the gradual improvement of steam engine and electric motors. With the development of technology, so far crushing machinery development has made considerable progress. Especially after the 1990s, crusher production and sales increased rapidly, while the number of enterprises continued to increase. These enterprises could produce 30 ton vibrating crusher, 24 to static roller crusher and 30 ton tire crusher and other range of varieties of products. They had self-development and production of complete crusher manufacturing system, and the gap with international advanced level was gradually narrowing. Therefore, crushing

machinery industry was entering a new period of development.

The large amount of construction waste has spawned a large number of construction waste disposal enterprises in China. After two years of development, the construction waste disposal companies gradually move towards a healthy and rapid development of road. At present, the construction waste disposal equipments researched and developed by Henan Hongxing Mining Machinery include the mobile crushing station and stationary crushing plant. There are more than 10 kinds of mobile crushing stations which include the roll jaw crusher series of mobile crushing station, PE jaw crusher series mobile crusher station, the JC jaw crusher series mobile crushing plant, HCP impact crusher series mobile crushing plant, HCS impact crusher series mobile crushing plant, PF impact crusher series mobile crushing plant, cone crusher series mobile crushing plant, VI impact crusher series mobile crushing plant, mobile screening stations and the track-type mobile crushing stations, etc..

The equipment can carry out muti-stage crushing for a large chunk of material. The equipment has small footprint, which can save a lot of infrastructure and relocation costs. The equipment can crush materials on-site without removing from the scene, which significantly reduces the transportation costs of materials. The construction waste crusher can be modified based on the actual site design which is very suitable for construction waste crushing. feed grizzly:http://www.china-mills.com/p11.html

Jaw crusher is widely used in mining, building materials, chemical industry, metallurgy industry, etc and crushing equipment, the function of the crusher cannot be ignored, but the daily maintenance and lubrication are very important. In addition to the correct operation, maintenance staff must have planned overhaul maintenance, including daily maintenance and inspection, repair and overhaul minor repairs, etc.

In industry, crushers are machines which use a metal surface to break or compress materials. Mining operations use crushers, commonly classified by the degree to which they fragment the starting material, with primary and secondary crushers handling coarse materials, and tertiary and quaternary crushers reducing ore particles to finer gradations. Each crusher is designed to work with a certain maximum size of raw material, and often delivers its output to a screening machine which sorts and directs the product for further processing.

The main structure of the Jaw crusher are composed of stander, eccentric shaft, belt pulley, flywheel, movable jaw plate, wrist plate ,adjustable gap screw, offsetting spring, fixed jaw plate. The wrist plate also has the effect of guarding.

This Jaw crusher's crushing style is the type of driving extrusion. The motor drives the belt and belt pulley to make the moveable jaw move through the eccentric shaft. When movable jaw is rising ,the included angle between the wrist plate and movable jaw become bigger to drive the movable plate to be close to the movable plate. At the same time the material is squeezed and rubbed, rolled to achieve multiple crushing;

When movable jaw is descending, the included angle between the wrist plate and movable jaw becomes smaller. Now the crushed material is discharged from the crushing cavity, with the continuous rotation of the motor, the movable jaw crushing and discharging the material periodically to realize batch production. mobile crusher:http://www.hxjq-mill.com/products/mobile_crushing_station.html

Crusher is a kind of construction machinery,and its waste materials whose row size greater than three millimeters take up more than 50 percent of total waste.Crusher is widely used in mining, building materials, cement, smelting, road, railway, water conservancy and chemical industry. crusher applications in the cement industry, paving industry and mining industry take up about 30% of the entire crusher industry. So crushers plays an important role in the national economy . There are all kinds of crushers including cone crusher, impact crusher and others. In this article, I will introduce you some main parts in a crusher and their different functions.

Cursher Engine

Engine is a way to put energy into a form more useful to another machine, usually into chemical energy into mechanical energy. (The electrical energy into the machine to the title of the motor) and sometimes both for power generation device, it can also mean the whole machine, including power plants, such as gasoline engines, aircraft engines, engine, also known as engine, is a way to put a forms of energy into more useful to another machine, usually into chemical energy into mechanical energy. A car engine to generate power devices. It will fuel combustion heat into mechanical power from the engine crank out the power output is required to power the vehicle driving source.

Eccentric Shaft

As the name suggests, the center of the eccentric shaft axis is not in the center of cylindrical axis parallel with the cylindrical workpiece without overlap, called the eccentric shaft. Normal axis, can only bring the workpiece rotation, but the eccentric shaft, not only to pass the rotation, while passing revolution. Now the U.S. giant compressor Copeland, is the eccentric shaft to drive the vortex of revolution and thus fast and efficient compression formulations. cement equipment:http://www.china-mills.com/p37.html
china magnetic separator:http://www.hx-crusher.com/magnetic_separator.html

The role of the eccentric shaft: In order to facilitate the adjustment shaft and the shaft center distance between the eccentric shaft normally used in planar linkage V-belt drive in! eccentric shaft is also widely used on crusher.

Crusher Bearing

Bearing in the mechanical transmission process and reduce the load from the fixed effect coefficient of friction. When other parts on the shaft when the relative motion to each other, the process used to reduce the power transmission coefficient of friction and to maintain a fixed mechanical shaft center.

Support is part of its role, t assume the role of the nature of the bearing radial load. Is the fixed rotation axis so that it can only be achieved, and to control its axial and radial movement. Without bearing the consequences of the motor is not work at all. Because the axis of movement in any direction possible, while the electrical work required for the rotation axis only. Bearing also affect the transmission, so in the high-speed operation of the bearing must be lubricated to achieve good

1. voice identification

To identify needs through sound experience. Must be adequately trained to recognize bearing sounds and non-bearing sound. Therefore, we should try to carry out this work by hand. With listening, or listening on a stick attached to the shell can clearly hear the voice of the bearing.

2. identify by the working temperature

This method is more recognition method is limited to use in running the state do not change the situation. To this end, the temperature must be continuously recorded. Failure, not only temperature, but also irregular changes.

Impact crusher is widely used in mining,cement, power generation, glass, chemicals, construction materials, metallurgy and other industrial sectors. In 1980s, we Chinese made crusher limited to dealing in coal and limestone and the like hard material. Until the late eighties to introduce our KHD-type hard rock crusher, fill the gaps. The machine work, driven by the motor, the rotor high-speed rotation, the material into the zone plate hammer, hammer and hit the rotor on the board broken, and then was thrown back again on the broken device, and from then on the back liner bounced back to hammer the role of district re-broken, this process is repeated, the material descending into one, two, three broken back cavity repeated until the material is broken to the desired size, from the discharge port.

Counterattack palte is an imporyant compenont of impact crusher. Counterattack plate stands the impact of the material, so that the material broken by the impact and the impact of broken material to re-bounce impact area, again the impact of fragmentation.

Many different types of counterattack plate , there are mansard counterattack plate and the arc counterattack plate . Broken line in the back plate back side to make the points are based on the material impact of near-vertical direction, so get the best of the crushing effect. Arc-shaped material block from the back side can bounce back plate came out, in the center area of the impact of the formation of intense crush zone to increase the impact of the crushing effect of free materials.

Welded steel plate back into general use, the back surface with wear-resistant lining, can also be counter-roller or the grate plates. Back seam with a grate surface content of fine particles less of their products, equipment, production capacity can be increased, power consumption province, but the structure is complex , it is difficult to replace the counter-surface wear, and it wears fast. china cement mills：http://www.hxjqchina.com/product-list_65.html

Stone from the machine directly into the upper high-speed rotation of the turntable; under the effect of centrifugal force at high speed, with another way to divert part of the umbrella to fly around the wheel high-speed collision with the stone produces high-density crushed stone in the fight against each other, then they will formed between the turntable and the chassis number of the vortex motion caused by each blow, rubbing, grinding, through discharge from the bottom. Form a closed loop several times, controlled by the screening equipment to the required size.

As a cost-effective best crusher,impact crusher has broad potential .There are two important points. First, the need for the existing impact crusher structure improvements to enhance the crusher on the hard ore crushing capacity and ease of maintenance, its main focus on the hammer, in order to improve the structure of the rotor plate Hammer replacement and installation card; back frame (broken cavity shape) of the structural optimization, an ore crushing rate increase and energy utilization. Second, the research and development of high toughness, high wear-resistant materials to improve a new type of hammer .

As the professional manufacturer of complete sets of mining machinery, such as china spiral classifier, Henan Hongxing is always doing the best in products and service.

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.
