2016-1-4 type mills have two grinding chambers for coarse and fine grinding. Grinding ball size and their distribution are designed and adjusted considering raw material conditions and mill dimensions etc. However, the energy efficiency in the coarse grinding chamber is extremely poor and there is limitation to improve both performances for

2015-8-19 Vertical Mills comprise 2-4 conical rollers which are hydraulically pressed onto a horizontal rotating grinding table. Material is directed onto the centre of the table and is thrown outward by rotation under the rollers. Fines pass out with the air current while coarse material falls back onto the feed table.

Principles of Operation. The grinding operation in Shri Krishna Roller Mills is performed on the principal of Attrition and compression, which results due to the centrifugal force generated from the suspended rollers running inside a stationary Bull Ring.. The material to be grind enters the grinding chamber through an automatic feeder and falls on the mills floor.

ergy usage. Roller mills can answer all of these demands for a wide range of chemical, pharmaceutical, food, min-eral, and other products. The mill is suited to reducing fri-able or fragile and breakable materials — that is, any material that breaks rather than flattens under pressure — in applications that require a uniform particle size with

In ring-roller mills rollers feed solid coarse particles against a stationary grinding ring. The particles are broken apart by the resulting compression forces. Equipment Design In a ring-roller mill, the material to be milled is fed into the grinding section . The moving roller forces the coarse material against the stationary grinding ring.

The special design of the pocket vanes works as a coarse material trap. The oversized coarse particles are carried by the airflow into the classifier where it impacts the angled pocket vanes, loses velocity and falls down to the grit funnel. The turbine rotor then provides an additional barrier that prevents oversized material from passing through.
