Mill Critical Speed Determination The "Critical Speed" for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell's inside surface This is the rotational speed where balls will not fall away from the mill's shell.

Ball mills grind material by impact and attrition The degree of milling in a ball mill is influenced by; Residence time of the material in the mill chamber The size, density and number of the balls The nature of the balls (hardness of the grinding material) Feed rate and feed level in the vessel Rotation speed.

Ball Mill Ball mill, an energy-saving grinding device, is widely used in mineral processing, building materials and chemical industri It 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 point where the mill becomes a centrifuge is called the "Critical Speed", and ball mills usually operate at 65% to 75% of the critical speed Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns speed rotation rock ball mill for mineral processing.

For ball milling, there is an optimum speed where the centrifugal force at the top of the mill is just balanced by the force of gravity This caused the balls to be lifted to the maximum height before they fall onto the balls below, thus imparting the most kinetic energy In practice, the ball mill is run at just below this speed (70-80%).
