What is the difference between vertical mill and ball mill?
(When the ball mill grinds the wet material, due to its limited air flow through the ball mill, additional drying equipment is usually required in front of the ball mill.) 4. The space occupied by the vertical mill is only 50%~70% of the ball mill, and the occupied physical space is relatively smaller. 5. Lower initial cost.

Mill (grinding) - Wikipedia
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

The finesse of the material milled by the ball mill is 0.074mm-0.4mm, only except for the two small ball mills that have a wider range of 0.075-0.89mm. However, the rod mill fine grinding fineness is about 0.833-0.147mm. In terms of the fineness of the ground material, the ball mill has a finer handling ability.

What Are the Differences between Dry and Wet Type Ball Mill?
The water can wash away the fine particles in time to avoid over-grinding. 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.
