What is the comparison of Raymond Mill and vertical Mill used in cement production?

It is well known that Raymond mill and vertical mill are core equipment in cement production line. Choosing the right one depends on the many factors such as: materials, input size, capacity, etc. Compare the two mills from the following aspects:

First, Different Structure

During operation, the position of the grinding roller of the vertical mill is fixed after adjustment. The grinding roller itself rotates like a pinion without direct contact with the grinding disc. The bottom grinding disc keeps rotating to remove the material in the gap between the grinding roller and the grinding disc. Carry out rolling milling.

The spring plum frame of Raymond Mill is equipped with 5 or 6 evenly distributed grinding rollers. The grinding rollers move in a circle around the shaft. The material raised by the bottom blade is sent between the grinding roller and the side wall grinding ring for grinding.

Second, Different Grinding Fineness Ranges

The particle size range of Raymond mill is between 325 mesh and 10 mesh.

On the basis of the Raymond mill, the vertical mill has been technically improved, and it is between 2500 mesh and 80 mesh.
