Our combined experience in ball mill design and process equipment development totals more than 60 years and allows us to put a unique spin on steel and lined mills.
A Ball Mill grinds material by rotating a cylinder with steel or ceramic grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. Ball Mills have been successfully run at speeds between 60 and 90 percent of critical speed.
Mill Speed - Critical Speed Mill Speed No matter how large or small a mill, ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar rolling mill, its rotational speed is important to proper and efficient mill operation.
Critical rotation speed of dry ball-mill was studied by experiments and by numerical simulation using Discrete Element Method (DEM). The results carried out by both methods showed good agreement.
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.
