Types of Crusher Machine
Stone crusher or stone crusher is a machine that is used to crush materials that can be crushed. Stones have different reactions to crushing: - Some are crushed easily. Some become powder. - Some are very resistant and abrasive. According to the type of stone and application, different stone crushers are used. Each stone crusher has a special method for crushing, which is divided into two main parts:
A-Squeezing crushing: (stone crushers; primary gyratory, jaw and conical), in this method, materials are compressed between two surfaces that approach each other and are crushed as a result. The speed of the crushing surface varies between 0.5 and 1.5 m/s.
B- Crushing in impact mode: (Horizontal shaft impact crushers HSI or Qubit and VSI vertical impact crushers). In this method, the materials are affected by the shock caused by the impact of the rotating parts (rotor, rock breaker hammer, sand bed, etc.) and are thrown towards metal surfaces (anvils) or non-metal surfaces (sand bed) This movement of stones also collides with each other. The movement speed is usually 30 to 80 meters per minute and sometimes higher in VSIs.
What is the Crusher's Work?
The task of reducing minerals and stones is the responsibility of stone crushers so that they can be used in the next stages of production. Stones are different in terms of wear and impact, compression and hardness, dimensions and moisture content, and these are things that should be taken into consideration when choosing types of stone crushers.
What are the types of crusher machine?
The types of stone crushers and the application methods of each stone crusher include jaw, cone, impact, hammer and cylinder crushers according to different materials. Fixed crushers are placed at the beginning of the production line. The raw materials are unloaded by trucks in the silo feeders of these crushers, and after being crushed, they are sent to the warehouse using a paper tape.
Crusher devices include:
jaw crusher
The jaw crusher is made of a fixed jaw and a movable jaw. The movement of the movable jaw is provided by an eccentric shaft connected to the motor with a belt pulley. With the action of the jaws, the material is subjected to the force of pressure (and sometimes by impact or shear) and is crushed. The distance between the two jaws in the upper part of the diaphragm and the distance between the two jaws in the lower part of the throat are called.
conical crusher
This is one of the types of rotary crushers, but it differs in some aspects, such as higher speed and a large increase in the angle of the cone core and, accordingly, the internal curvature of the body.
Roll Crusher
It is made with one or more heavy rollers with smooth or grooved surface. The movement of opposite rollers is opposite to each other and their rotation speed is equal or close to each other. The distance between the two rollers is adjustable. The basis of the work of these stone crushers is based on the friction between the stone and the rollers. Because these crushers are different in terms of the number of rollers.
impact crusher
The impact crusher consists of a rotor with multiple blades and rotating at high speed. The role of the blades is to throw the incoming load parts to the inner wall of the crusher. A series of shields made of manganese steel are placed on the inner wall of the device. These shields act as a barrier and will be crushed if the parts of the incoming load collide with them.
hammer crusher
In hammer crushers, the crushing process takes place by rotating our hammers between the rotor and hitting the anvil.
A hammer crusher is a type of stone crusher that has powerful stone crushing equipment used to crush and break minerals such as stones that come out of the mine.
