What is a crusher
Crushers are machines that break medium and high hardness materials and bring them to asphalt and concrete aggregate dimensions. The crusher can perform primary, secondary and tertiary crushing by means of three stage crusher pendulums. It has versatile use area. Crushers which are from jaw adjusted impact crusher class, are crushers that break medium and low hard materials (such as limestone and dolomite) into asphalt and concrete aggregates size. Large material feedability, cubic product, high reduction ratio, high capacity, low investment and operating costs make this type of crushers the ideal secondary crusher in crushing and screening plants.
Types of Crusher
It is very crucial to mention the types of crushers to fully understand the crushers. In this point of view, two types of crusher will be examined as example. These types are jaw crushers and primary impact crushers.
They are primary and secondary crushers which are designed to break all kinds of materials, regardless of hardness and abrasiveness. They are jaw crushers that stuck and crush the material by means of the elliptical movement of the movable jaw between the stationary and movable jaw. It is the most preferred of primary crushers with its settings made by hydraulic system and also its high performance and efficiency.
Primary Impact Crushers
They are the high capacity rotary crushers that work with medium-hardness and low-silica materials with high reduction and cubic rate. It is used for breaking large size stones thanks to special alloy packages and crushing plates. It is used in primary and secondary stages in practice; Especially in primary applications, the high rate of fine material produced by jaw crushers decreases the secondary level of crumple and therefore secondary crushing does not require in some applications.
