Powerful Planetary Ball Mills

Mechanical Structure of Powerful Planetary Ball Mills

The powerful planetary ball mill is composed of a feeding part, discharging part, rotating part, transmission part, reducer, small transmission gear, motor, and electric control. The hollow shaft is made of cast steel, the lining can be disassembled and replaced, the rotary gear is processed by casting hobbing, and the cylinder body is inlaid with a wear-resistant lining plate, which has good wear resistance. The powerful planetary ball mill runs smoothly and reliably.

Steel Balls for Powerful Planetary Ball Mills

The main function of the powerful planetary ball mill is to impact and crush the materials, and it also plays a certain role in grinding. Therefore, the purpose of steel ball grading is to meet the requirements of these two aspects. The crushing effect directly affects the grinding efficiency and ultimately affects the output of the ball mill. Whether the grinding requirements can be achieved depends on whether the grading of steel balls is reasonable, mainly including the size of steel balls, the number of ball diameters, and the proportion of various sizes of balls.

In order to determine these parameters, in addition to factors such as the size of the powerful planetary ball mill, the internal structure of the ball mill, and the requirements of the product fineness, the characteristics of the materials to be ground should also be considered.

In order to effectively crush the materials, the following principles must be followed when determining the gradation:

First of all, the steel ball should have enough impact force to make the steel balls of a powerful planetary ball mill have enough energy to grind granular materials, which is directly related to the maximum diameter of the steel ball.

Secondly, the steel ball should have enough impact times on the material, which is related to the filling rate and average diameter of the steel ball.

Finally, the material has enough residence time in the powerful planetary ball mill to ensure that the material is fully ground.
