Mills of the UMS type have a station ary steel plate inlet funnel that leads the venting air into the mill through a protrud ing central cone bolted to the web of the slide ring. The funnel is equipped with a throttle valve and a pressure monitor to adjust the pressure at the inlet end, thus preventing dust emission from the inlet.

The water can wash away the fine particles in time to avoid overgrinding. The wet ball mill has a low noise, and low environmental pollution. The wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%10% lower than that of a dry ball mill. The grinding particle size is fine and uniform.

Ball mills are usually either of the grate ( diaphragm) or overflow type. Ball Mill Components Ball mills consist of the following components: Inlet crushed ore is fed to the ball mill through the inlet. A scoop ensures the feed to the mill is constant. Discharge reduced feed exits the mill through the discharge. Ball Mill Components

Principle of Fluid Energy Mill: It operates on the principle of impact and attrition. The inlet and outlets are attached with the classifier which prevents the particles to pass until they become sufficiently fine, (a). It helps in the determination of particle size and shape. The speed of air/inert gas is directly related to efficiency.
