What's a stone crusher? A stone crusher is a type of pulverizer that uses mechanical energy to break blocks of stone, concrete, or other building materials into smaller blocks of a specific grain size.
An impact crusher uses mass and velocity to break down feed material. First, the feed material is reduced as it enters the crusher and makes contact with the rotating blow bars or hammers in the rotor. Secondary breakage then occurs as the material is accelerated into the stationary aprons or breaker plates.
A roll crusher and a hammer mill are both types of industrial crushers used to break or crush materials. While they share some similarities, they also have key differences in terms of their ...
Hammer mill is designed to break materials through the hammer at a high speed. Therefore, the installation of foundation and rotating shaft must be strict, which requests that the longitudinal and axial deviations are not more than 0.5/1000mm and 0.1/1000mm respectively.

A crusher, also known as a stone crusher, is a machine that uses mechanical action to break large rocks, ores, or other raw materials into gravel or rock powder. Crushers are widely used in ore crushing, aggregate production, construction waste recycling, and natural stone processing.
However, certain materials (so-called uncrushables) cannot be crushed and can cause damages inside the crusher box and stop your production. If you feed uncrushables in your compact impact crusher, anything can happen. You can break a hammer on your impact crusher. You can bend your rotor shaft. You can damage conveyor belts.
Hammermill Crushers are known to generate material finer than 3/16" (4mm), which in some applications may be undesirable. However, if there is a market for finer material, or if it is acceptable within the desired product size, Hammermills can achieve reduction ratios that may otherwise require multiple crushers.
