How to choose the right crusher?

06/09/2021

A crusher is a machine that uses mechanical energy to break blocks of stone, concrete, or other building materials into smaller blocks of a specific grain size.

Crushers are classified according to the fineness with which they fragment the starting material. There are primary or secondary crushers (coarse finished products) and tertiary or quaternary crushers (fine particle finished products).

How to choose a crusher?
There are several characteristics to consider:

1, The abrasiveness and hardness factor. It is essential to know what material is going to be crushed, in particular its abrasiveness and hardness. You must evaluate the compressive strength or maximum force that the material can withstand before breaking.
2, The dimensions. You will need to consider the maximum dimensions you need to enter into the machine (length, width and thickness).
3, Granulometric requirement. It is necessary to define the desired result i.e. the grain size after crushing.
4, The capacity (throughput). You will need to determine the processing capacity (or throughput) necessary for your use. This is measured in tonnes/hour.
