Ball mill Wikipedia A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing .
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.

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. Too low a speed and little energy is imparted on the product.
Describe the components of ball mill. Explain their understanding of ball mill operation. Explain the role of critical speed and power draw in design and process control. Recognize important considerations in ball mill selection. Reading & Lecture. In ball mills, steel balls or hard pebbles to break particle based on impact and attrition.
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%).

Rotational speed for ball mill. ... 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 .
The optimum speed varies as a percentage of the critical speed depending on the viscosity of the material being ground. For the dry powders used in pyrotechnics, the optimum speed will be 65% of the critical speed. Using the interactive calculator on this page will help you determine the optimal speed for your mill without having to reach
