The need of ball mills to produce fine grain cement is unavoidable They require hundreds tons of grinding balls and liners in order to produce large volume of cement each year A material of grinding balls and liners requires good mechanical properties such as high impact strength high hardness strength and high wear resistant to the plants are importing the material from other countries
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 If the peripheral speed of the mill is too great it begins to act like a
Ball mills consist of cylinders partially filled with large numbers of steel balls which employ their rolling action to crush the raw material when each cylinder is rotated High pressure roller mills are occasionally used to grind clinker although their use has not yet gained broad acceptance A cement mill is used to make clinkers which are key in many types of concrete The chief

Coarse clinker is more of an issue for ball mills Some cement groups use a formula such as Bond s to calculate the maximum ball size required in a ball mill based on the average size of the clinker feed However one drawback with this approach is that in some cases the formula will result in the prediction that 100mm balls be used to deal with large clinker particles The trouble with
