Function Principle of Vertical Mill

The primary composition and performance of the vertical mill.


The grinding roller is really a main portion for rolling and grinding the components. Within the mill there are 2 pairs of grinding rollers. Each pair of grinding rollers is mounted on the very same shaft with rotation at different speed.

What's a lot more, the millstone is fixed within the output shaft from the speed reducer. There may be materials mattress about the upper millstone and ring groove underneath the material bed.

PRM vertical mill is mainly built up with the cement separator, the grinding roller, micropipette, strain device, reducer, electromotor, shell and also other components.

Among them, the separator is a significant component that is certainly in a position to determine the fineness. Simultaneously, it is made up of adjustable transmission device, rotor, wind lead leaf, shell, and thick powder blanking cone, outlet and also of components. It has the comparable operate principle as the classifier.

The pressure machine may be the portion that gives the grinding stress. Simultaneously, it is created up using the high pressure oil final, hydraulic cylinder, bars, accumulator and also other elements. Meanwhile, it could put sufficient pressure around the grinding roller for crushing resources.

The operating principle:

First, the supplies in air circulation undergo the separator. The coarse components go through the cone for the chute below the influence of the turning vane and also the rotor. Simultaneously, the great powder is discharged from the mill together with the wind movement. Then, the powder, particularly the merchandise, is collected in dust amassing gadget of the program. The supplies contacts with the air and in the way they are dried to meet the moisture necessity from the goods. What's a lot more, adjusting the angle in the turning vane and the rotation speed in the separator rotor has the ability to get goods of various levels of fineness.

The motor drives the millstone by way of the reducer. The current sizzling air enters into the mill in the air intake. And the supplies fall on the chute in the feed opening. Due to the position of the centrifugal force, the components move round the edge of the millstone. Once they undergo the ring groove within the millstone, the grinding roller will grind and crush them. Following, they still move across the fringe of the millstone until finally they rise in air with large grains that fall immediately again to the millstone for grinding.
