Roller mills, particularly single pass installations, require more care and attention than hammermills in order to achieve a consistent and accurate grind. Ensuring the feed is spread thinly across the face of the roller mills can present some problems as mechanical feed gates can easily become obstructed, impairing the smooth and regular flow ...

Due to the contact angle, tapered roller bearings can handle high radial and axial forces in one direction. Tapered roller bearings can provide low friction, long service life, and enhanced operational reliability. Tapered roller bearings are commonly used in gearboxes, hoisting equipment, rolling mills, and machines in the mining industry.

A conical mill (or conical screen mill) is a machine used to reduce the size of material in a uniform manner. It is an alternative to the hammermill or other forms of grinding the name implies, the conical mill varies in diameter from where the feed enters to where the product exits. The conical mill operates by having the product being fed into the mill by gravity or vacuum. A ...

With the singleroller mills, brittle, soft to mediumhard materials can be reduced in size with a reduction ratio of approx. 1:5 to 1:5. The stepped arrangement of the crushing jaws on the crushing wall enables any material rolling off being minimised, so that, compared to the doubleroller mill, coarser material can be drawn in.
