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 are the causes of the noise in the crusher? 5 ways to solve the noise of crushing machinery
As a modern mining machine, the common stone crusher is a kind of equipment with high noise pollution, and its noise problem has always been one of the problems that mine machinery enterprises need to solve.(a) the machine fault machine fault can cause additional noise, such as the belt deviation may cause the product belt striking sound, such as problems arise, excessive noise hit the stone crusher produces machine, machine resonance noise led to a decline in the foundation. In case of this kind of noise, contact the technical personnel for the first time to solve the problem and avoid further losses.(two) reduce the noise of sound source; 1., transform the production process and choose low-noise equipment.
Q:What are the structural features of the roll crusher?
The utility model has the advantages of simple and compact structure, low noise and high efficiency;The installation is flexible and basically requires no foundation;Pressure regulation, particle size adjustment is convenient and reliable;
Q:What kinds of crushers are there?
Cone crusherThe working principle and gyratory crusher, crushing machine but only apply to pieces or fine crushing. The discharge uniformity in size, fine works of general than crushing operation requirements, therefore, in the lower part of the crushing chamber must set a parallel region, at the same time, it must accelerate the cycle of crushing cone in order to speed the material in the parallel region squeezed more than once.The crushing of a relatively coarse crushing crushing operation is large, so the broken loose volume will be greatly increased. In order to prevent crushing cavity may therefore cause obstruction, without increasing the discharge port to ensure the premise of discharging granularity required under must by increasing the diameter of the lower crushing cone to increase the exhaust the total material section.The cone crusher discharging opening is small, with non broken material in more prone to accidents, and because, in fine crushing to the discharge size requirements strictly, must be in the liner wear in time after adjusting the discharge, so the cone crusher insurance and adjusting device of coarse crushing machine is more necessary.Simon type spring machine overload insurance cone crusher, cone shell forced the compression spring and make their own increased, so as to increase the discharge, discharge the non crushing matter. The discharge opening adjustment by adjusting the set of adjusting sleeve is fixed with the casing can rotate with the outer circle of the screw to drive the shell to rise or fall, to change the size of the discharging port. The hydraulic cone crusher insurance and the adjustment way and hydraulic breaker is the same.
Q:What is the hammer piece of the crusher?
Thereby, the production efficiency is improved, the process is convenient to manufacture, the process is simple, and the cost is low. The utility model can be widely used for various types of hammer mills at home and abroad.
Q:Is the price of large cone crusher expensive?
Other crushing equipment can be adjusted according to the material and output you handle;
Q:Caterpillar crusher hb40g what does that mean?
The mobile station has excellent mobility and site adaptability, without stationarycrushingstation installation required in the preparation, can be completed in a short period of time to adjust the position, ready to enter the working state. It can reduce the material handling operation
Q:Hammer crusher vibration is big, how to do?
The reason of large vibration amplitude of hammer crusher
Q:What about shock and blockage in hammer crusher?
During the operation of the hammer crusher, the vibration of the machine is one of the common faults. There are many reasons for the machine vibration, and can be broadly divided into the following:
Q:What's the flywheel on the jaw crusher?
Because the jaw crusher works intermittently, then the flywheel has working and idling conditions during the operation of the equipment. Therefore, the load and the motion state of the flywheel motor are quite unbalanced. In order to make the flywheel motor load evenly in crusher Hubei from the fixed jaw plate move backwards, can put the idle state energy storage, for when the crusher ore energy can be fully released. When the equipment is designed, the flywheel is installed at both ends of the eccentric shaft, mainly for the purpose of using the inertial principle.
Q:Principle of roll crusher, how about the output of 610*400 roller crusher?
When working, the motor drives, the high-speed rotation of the rotor, the material into the plate hammer function area, and the impact of the rotor plate hammer broken, and then thrown to the back device broken again, and then board the bomb on the back plate hammer area again broken from the back lining, this process is repeated by material to enter the one or two, three, back cavity repeated broken, until the material is crushed to the required size, discharged from the discharge port.
