Ball Mill Mechanical Formulas Advance Grinding Machine

All grinding mill ball mill manufacturers understand the object of the grinding process is a mechanical reduction in size of crushable material grinding can be undertaken in many ways the most common way for high capacity industrial purposes is to use a tumbling charge of grinding media in a rotating cylinder or drum

Apr 18 2020 a ball mill grinds material by rotating a cylinder with steel grinding balls creating the ball fall back into the cylinder and onto the material to be ground its rotation is depending upon the diameter of the ball mill and usually 4 to 20 revolutions per minute

For ball milling you can assume a porosity of about 035 to 040 the volume of space between the balls and you can normally assume the pulp surface level is equal to the ball charge surface level so do a crashstop and measure the volumetric filling of the charge then multiply that volume by 035 or 040
