Jaw Crusher Description

The jaw crusher we offers are ideal for primary and secondary crushing. Jaw Crusher is one of the main types of primary crushers in a mine or ore crushing process plant and also is one of the most widely used crushing equipments in mining industry.We are famous jaw crusher manufacturers in China, and sold crusher machines to all over the world. This series of jaw crusher can reach the crushing ratio of 4-6 and the shape of final product is even. Because it is primary crusher, Jaw crusher is designed for long life service with minimum maintenance for hard, tough, abrasive material and overload high capacity


Jaw Crusher Working Principle
Primary jaw crusher is typically of the square opening design, and secondary jaw crusher is of the rectangular opening design. Jaw Crusher reduces large size rocks or ore by placing the rock into compression. A fixed jaw board, mounted in a "V" alignment is the stationary breaking surface, while the movable jaw exerts force on the rock by forcing it against the stationary plate. The space at the bottom of the "V" aligned jaw plates decide the crusher product size gap, or the size of the crushed product from the jaw crusher. The rock remains in the jaw until it is small enough to pass through the gap at the bottom of the jaws.


Brief introduction to stone crushing & screening plant

we manufactures various equipments for whole set of stone production line, and provide complete technical support for customers. The whole production line consists of Vibrating Feeder, Jaw Crusher, Impact Crusher, vibrating screen, Belt Conveyor, electric control cabinet and etc.

 

We design different production lines ranging 50 t/h to 500 t/h by combining different models of equipments.It is widely used for crushing hard limestone, granite, basalt, gravel, metallurgic slag, etc or artificial sand making for hydroelectric power, building material, high way, city construction, etc. Different models of equipments are combined to meet different customers' demands according to different craft requirements.

Process of stone crushing & screening plant

1. Big rocks are transported to the working site of stone production plant from quarry.

2. The rocks are transferred to primary crusher by vibrating feeder. Once there is a hopper prior to the vibrating feeder, the rocks are stored in the hopper firstly.  

3. The crushed materials are transferred to Impact Crusher by Belt Conveyor for secondary crushing.

4. The materials are transferred to the vibrating screen, and screened into different sizes.

5. Those aggregate with suitable size will be transferred to the final product pile; while those with unsuitable size will be transferred to the Impact Crusher for re-crushing.

 Vipeak stone crushing & screening plant

This forms a closed circuit manifold cycles. The sizes of final products will be graded and separated according to customers' requirements and application, and the deduster will be attached for the sake of environment protection.

 

Main advantages of stone crushing & screening plant

1. Customerized design

The production line is designed according to customer's requirement on the output size, types of output and capacity, as well as other factors such as material property, site conditions and purpose.


2. High efficiency and low cost  

The arrangement of the machines in the production line can work efficiently and act for the maximum effect, which can ensure the efficiency and increase the output in unit time so that to lower the average cost of finished product (per ton).

 

3. Standard component

It is much convenien for replacement and maintenance of the machines. Shorten the shutdown time resulted from those maintenance.

 

4. Optimized production flow 

The optimized production flow can ensure the capacity of the whole production line, the density of piling up and the shape of finished product, to satisfy the various purpose of product.

Q:What's the difference between a jaw crusher and a hammer crusher?
Working principleThe PE series jaw crusher three-phase asynchronous motor machine through the belt drive rotor eccentric shaft rotation speed according to the regulations, hanging on the eccentric shaft and the lower jaw head push toggle plate on the eccentric shaft eccentric support, drives the movable jaw plate along the trajectory of movement, relatively fixed plate extrusion, shear movement in order to achieve the material, crushing, crushing less than row trajectory of feed helps to lower bulk materials, long elliptic trajectory makes the higher yield and grain size is more uniform. The sudden increase of load into the crushing chamber can not be broken in foreign material, toggle through their own fault protect other parts from damage.
Q:When plastic film is broken, how can the film paper not be copied and swallowed? What's the principle? 60 crusher
You use a high-speed crusher, high-speed rotation will produce a certain amount of wind, plastic film is too light, can not overcome the wind, so do not copy down the pharynx.
Q:The working characteristics of compound crusher
(1) the structure is simple and reasonable, and the running cost is low. The use of stone stone stone principle, small wear. (2) high crushing rate and energy saving.(3) it has fine crushing and coarse grinding function.(4) the water content of the material is little affected, and the moisture content can reach 8% or so.(5) more work noise is less than 75 decibels (DB level), dust pollution is less.(6) suitable for crushing medium, hard and hard materials.(7) the products are cubic, the density is large, and the iron pollution is very small.(8) impeller lining, small wear and easy maintenance.
Q:Are there any machines that can break stones into 1.5mm? The laboratory can not be too fine, you can go through 10 mesh screen. Except for grinding machines
10 purpose screen mesh between 1.8-2.2mmCan not roll such a large particle on the bar?
Q:Reasons for flying cone of CH870 cone crusher
Improper eccentricity of eccentric shaft. When the eccentric part of the gap is too large, easy to cause the eccentric sleeve and the spindle tilt, affect the lubricant film formation, destruction of the equipment to normal lubrication conditions, resulting in local overheating makes the moving cone cone sleeve can not be stable, resulting in vehicle instability phenomenon.
Q:What are the types of crushers?
Crusher typeJaw crusher, impact crusher, cone crusher, vertical impact crusher, single stage hammer crusher, non reversible bar hammer crusher, single cylinder hydraulic cone crusher, multi cylinder hydraulic cone crusher, Simmons cone crusher, hammer crusher, counterattack hammer crusher, hammer crusher, high efficiency single stage hammer crusher, double roll crusher, sieving type tooth crusher.
Q:Ask for help, stone, I used a broken plug-in
Sand and stone should be used to repair roads. It is recommended that you use the PFL vertical hammer composite crusher, which can be used as stone for crushing and making sand, and for repairing expressways, this crusher is often used.
Q:Can the concrete pavement be broken down and can be loaded directly with the loader?
Loaders are cheaper than excavators, but mainly depending on the size of the workplace. If the area is larger, loaders are used, and the smaller ones are only relatively expensive excavators, and they are less efficient
Q:Where are the crushers located?
It is used in mines, cement, coal, metallurgy, building materials, highways and combustion departments
Q:What are the requirements for the installation of jaw crusher?
Requirements for installation of jaw crusher:Because the jaw crusher machine at work vibration is large, so the machine should be installed in reinforced concrete structures on the basis of the weight of approximately 8-10 times the desirable weight of the machine, the depth of the foundation is greater than the soil freezing depth, provided that the base graph size for the host and the relative position of the motor bolt and other relevant parameters, as construction plans. The installation of anchor bolts must be provided with reserve holes as the basis for the two grouting. The height and the size of the blanking tank are determined by the field according to the discharging method at the lower part.
