Wilczek: The mill accepts a maximum particle size of about mm for hard and up to 4mm for softer materials. One typical characteristic of the mill is the high energy density, 1020 times higher compared to a ball mill, resulting in a very compact design. The high energy density in the small grinding chamber requires a fast material transport.
The ball and tube mills are lowspeed machines that grind the coal with steel balls in a rotating horizontal cylinder. Due to its shape, it is called a tube mill and due to use of grinding balls for crushing, it is called a ball mill, or both terms as a ball tube mill. These mills are also designated as an example size, BBD4772,asdadasd
Ball mill is crucial to numerous industries as an equipment for producing extremely crushed materials, cement, refractory materials, fertilizers, glass ceramic, ore dressing of ferrous as well as nonferrous metals, etc. Ball mill can be used to grind ores and other materials which can be both wet and dry.

2. BALL TUBE MILL Tube and ball mills: These are lowspeed machines that grind the coal with steel balls in a rotating horizontal cylinder. In stage II ball tube mills are used. Ball and Tube Mill is basically horizontal cylindrical tube rotating type of mill at low speed on its axis, whose length is slightly more to its diameter.
It is very noisy machine. 3. Ball mill is a slow process. 4. Soft and sticky material cannot be milled by ball mill 5. At low speed, the balls will slide or roll over each other and only negligible amount of size reduction will occur. 6. At high speed the balls will be thrown out to the wall by centrifugal force and no grinding will occur.
