Different specification steel balls are installed on the scale board in the ball mill, when the barrel body rotates and produces centrifugal force,at this time, the steel ball is carried to some height and falls to make the material grinding and striking. The speed of rotation is the greatest important factor in the operation of the ball mill.
involve grinding). With Lloyd's ball milling book having sold over 2000 copies, there are probably over 1000 home built ball mills operating in just America alone. This article borrows from Lloyd's research, which was obtained from the commercial ball milling industry, and explains some of the key design criteria for making your own ball mill.

This ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. Due to the difference of its slurry discharging method, it is divided to two types: grid type ball mill and overflow type ball mill.
To get rid of pulp and rocks in the charge, a mill grind-out (no ore feed) of 10 to 20 minutes is also performed before mill inspection or relining. The complete grind-out is required to obtain the accurate ball load measurement or the percentage by volume of balls in the mill. This is usually performed soon after a crash stop.
6. Possible Defects. 7. Design Rules. 8. Cost Drivers.

To be chosen according to the grinding material, material is composed of a ball mill feed end of the hollow shaft is arranged in the tube body, when the ball mill cylinder rotation time, grinding body due to inertia and centrifugal force, the effects of friction, making it attached to the cylinder liner on the cylinder body away, when taken to the height of a ...
Design and operating principle. A ball mill is a hollow drum rotating around its horizontal axis. It is filled with grinding balls (impact elements). As a result of rotation, balls on the internal drum surface lift and then fall down under the gravity action. The source material is permanently fed through one of spigots.

The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force.
design parameters need to be understood. Figure 3: exploded ball mill assembly, computational model Pinion The original design calculations were not available so Principia had to reverse-engineer most of the design (see Figures 3, 5 and 6).
