Vertical mill is a kind of grinding equipment evolved with the development of industrial grinding. In terms of working principle and equipment technology, vertical mill and ball mill are quite different.

Working principle:

The ball mill is composed of a horizontal cylinder, a hollow shaft for feeding and discharging materials, and a grinding head. The ball mill uses the centrifugal force and friction force of grinding bodies such as steel balls and steel bars to grind materials.

The vertical mill integrates crushing, drying, grinding, and grading and conveying. Compared with the ball mill, the vertical mill has a simple process, less capital investment, and does not require grinding media. It is a crushing and grinding media by itself. The grinding pressure of the grinding roller is used for grinding. The solid raw material enters the center of the grinding disc from the feed port through the air-locking feeding device, and is thrown to the periphery of the grinding disc under the action of the centrifugal force field, and is crushed by repeated rolling by the grinding roller.

Equipment structure:

The vertical roller mill has a simple structure, adopts vertical installation, small floor space, simple infrastructure, convenient installation, and short time-consuming. However, the structure of the ball mill is more complicated, adopting horizontal horizontal installation, the installation technology is difficult, the foundation requirements are high, the cycle is long, and the floor space is large. Both can be arranged in the open air, but generally speaking, the construction area of the vertical mill is 70% of the ball mill, and the construction space is 50%-60% of the ball mill, and the investment cost is low.

In summary, the vertical mill equipment has the advantage. The vertical mill system has simple process, low failure rate, high operation rate and compact layout. Generally speaking, the finished product of the same fineness adopts the vertical milling process. After two stages of grinding, the fineness of the product can reach the required level. The traditional ball mill process requires three stages of grinding.
