of mill speed in a mill on the material in mining industry

The faster the mill speed the greater the wear on the rods and liners So the general rule of thumb for rod mills is to operate no faster than the speed that will obtain the desired product size The operation speed of rod mills is generally determined by the Peripheral Speed of the Inside of the mill Generally rod mills operate between 280

A Ball Mill grinds material by rotating a cylinder with steel grinding balls causing the balls to fall back into the cylinder and onto the material to be ground The rotation is usually between 4 to 20 revolutions per minute depending upon the diameter of the mill The larger the diameter the slower the rotation

This condition is reached at about 60 to 80 percent of the critical speed of the mill where the centrifugal force is high enough to prevent the media from completely falling back down on the material bed

Ball mill machine can also be used to grind a small number of materials for experimental research in machinery hydropower light industry and agriculture Cone Ball Mill is a highquality ball mill crusher The conical ball mill can grind many metal ores Lab mill has the advantages of high grinding accuracy large production capacity simple
