Ground particles discharged by gravity from bottom roll pair's roll gap. More about the rolls. Common roll diameters are from 6 to 10 inches, and roll lengths — which vary with the roll diameter to ensure that the roll will be mechanically robust — are from 8 to 52 inches. Longer rolls provide greater grinding capacity.
A popular type of vertical spindle mill is the ring-roller mill. General Information. 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.
Hammer mill is easy to install, operate, dismantle and clean up. It occupies less space and can be easily placed in one corner of the manufacturing area. Various grades of material can be handled using screens of different sizes. It is versatile, and speed and screens can rapidly change based on milling requirements.
