The air classifier mill process. An air classifier mill, also known as an air classifying mill, uses airflow to separate particles by size. The mill consists of a grinding chamber, a classifying wheel, and a fan. The raw material to be ground is fed into the grinding chamber, which is impacted by a highspeed rotor fitted with hammers or pins.
Prater's air classification mills can adjust the centrifugal force used to separate particles by size. Conveying raw product to a primary air inlet, the drag forces within the classifier cause the moving air to act on individual particles, depending on the size and density of the material.

Jaw crushers. Jaw crushers were invented in 19 th century and are mainly used as primary crushers to produce material that can be transported by belt conveyors to the next crushing stages. The crushing process takes place between a fixed and a moving jaw. Shaft rotation, along with the toggle plate, causes a compressive action of the moving jaw.
