Crusher refers to a crushing machine whose particle size is greater than 3 mm in the discharge, accounting for more than 50% of the total discharge. Crushing operations are often divided into coarse crushing, medium crushing and fine crushing according to the size of feeding and discharging particle size.
Classification of crushers
Commonly used crushing machinery includes jaw crusher, gyratory crusher, cone crusher, roller crusher, hammer crusher and impact crusher.

Crusher use
The crusher can process the production of building aggregates, cement concrete, road fabrics, cushion materials, asphalt concrete and other aggregates. River pebble sand making machines are often seen in these industries.
The crusher can be used in the production and shaping of machine-made sand in industries such as highways, airport runways, high-rise buildings, high-speed railways, municipal engineering, water conservancy and hydropower, and passenger dedicated lines;
The crusher can be used in the material crushing and fine crushing process in mining, building materials, cement, chemical industry, metallurgy, refractory materials, mining and other industries;
The crusher can also be used in environmental protection projects such as construction waste crushing and steel slag crushing, and can process other high-purity materials such as quartz sand and glass, as well as in the production of sulfur removal in thermal power and metallurgical industries.
