Nov 29, 2016 Difference Between Vertical Mill and Ball Mill Posted: 2016-11-29. Vertical mill mainly applied to powder processing of non-flammable and explosive brittle materials with medium, low hardness, Mohs hardness of 6. Ball mill is key grinding equipment afer materials are crushed. Vertical grinding is a "grinding bed" grinding equipment, and ball mill is "single-particle grinding" grinding

Hammermills versus roller mills World-grain

Roller mills simply “roll” or “crush” product between two revolving cylinders. This latter process has the distinct advantage of requiring considerably less power, although it is not possible to achieve the fineness of final grind through a roller mill that can be achieved through a hammermill. In a hammermill, the screen-hole diameter

Tumbling ball mills or ball mills are most widely used in both wet and dry systems, in batch and continuous operations, and on a small and large scale.. Grinding elements in ball mills travel at different velocities. Therefore, collision force, direction and kinetic energy between two or more elements vary

What's the difference between a Roller Mill and a Hammer

The difference between a roller mill and a hammer mill is: A hammer mill uses rotating hammers to pound grain through a screen and it requires a lot of horsepower. You get a lot of powder with larger deviation from the hammering.
