Vertimill® has 50% less footprint than a ball mill. Lower operating cost Vertimill® is an energy efficient grinding machine. They tend to grind more efficiently than, for example, ball mills with feeds as coarse as 6 mm to products finer than 10 microns. This provides up to a 40% higher energy efficiency.
The ratio of active mill shell surface area to ball charge surface area for the 5.0 meter (16½ foot) unit, is roughly half of that for the 2.4 meter (8 foot) unit. However, the actual ratios are so small (1 or 2 percent) that the amount of grinding at the shell is likely of little significance for either size.
The speed of ball mill rotation is a critical parameter which determines the grinding efficiency and the end product quality. The optimum speed will differ depending on the mill's diameter, the size and density of the grinding media, and …

This radius increases tool strength and wear resistance by distributing cutting forces over a larger area, which is particularly advantageous when milling more complex materials or when the cutting edge is under …
The purpose of the trommel screen is to classify the ball mill discharge, by size, into two separate streams. OPERATION. Ground ore slurry exits the ball mill over a trommel screen (Equipment Specifications). The trommel has a slotted screening surface, and material that is too large to pass through the trommel goes into the ball mill scats bunker.

One of the most used tumbling mills is the ball mill. This paper reviews different types of grinding media that have been developed and improved over the years and their properties.
IV. BALL MILLS Ball mills are one of the more common mills and use a closed cylindrical container that is rotated horizontally on its axis so that the media cascades. A typical ball mill has an L/D ratio of 1.5:1. Ball mills are filled with spheres or other shapes made of steel or ceramics; or with pebbles made of flint (or of an ore being ground).
