The article analyzes virtual experiments of the lining of a ball-type drum mill depending on a number of factors: the diameter of a mill, the diameter of grinding bodies, the number and height of liner lifters. The numerical experiment was performed using the EDEM software; a parametric model of the mill housing with variable liner lifters was created and imported, studies were performed using ...A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity. Today, the largest ball mill in operation is 8.53 m diameter and 13.41 m long with a corresponding motor power of 22 MW (Toromocho, private communications).

4. Load lime stone to the ball mill along with metal balls. 5. Run the ball mill for 40 minutes at the speed 1 rpm. 6. After 40 minutes take out lime stone powder from the ball mill. 7. Fill the lime stone powder to new set of sieves of small sizes. Keep the sieves on the vibrator for 20 minutes. 5 · The ball mill machine is driven by the motor to rotate, so as to realize the operation between the material in the barrel of the ball mill machine and the steel ball. When the medium inside the cylinder is brought to a certain height with the rotation of the ball mill machine, the medium will fall due to its own weight.1 Full PDF related to this paper. READ PAPER.

· The disadvantages of ball mills include their considerable metal consumption and deterioration grinding media, as well as a lot of noise. Most of the energy useless lost during ball mill operation, leading to low it efficiency. But even a significant specific energy consumption for grinding material compensates beneficial effect by using mill. · The ball mill machine is driven by the motor to rotate, so as to realize the operation between the material in the barrel of the ball mill machine and the steel ball. When the medium inside the cylinder is brought to a certain height with the rotation of the ball mill machine, the medium will fall due to its own weight. · A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls,flint pebbles.
