How Does a Vertical Roller Mill Work?

A vertical mill operates on the principle of material bed grinding, where raw materials undergo a precise grinding process. Here's how it works:

The mill's motor powers the rotation of the grinding table, causing materials to descend towards the millstone's center from the feeding inlet. Concurrently, hot air is introduced into the mill through the air inlet.

As centrifugal forces take effect, the material migrates toward the outer periphery of the millstone. During this journey, it passes through the millstone's annular groove, where it is meticulously crushed by the grinding rollers.

Subsequently, an airflow transports the ground material to a separator. Within the separator, fine particles are isolated and collected, forming the ultimate product.
