How do I control the Raymond mill output to a smaller size?

In grinding, once a Raymond Mill machine is ensured, a grinding ratio is ensured with it. As for the output size, it can be adjusted to specified figure. Even though, we can also have ways to diminish its output size.

First, we should control the input size. When grinding ratio is certain, the smaller the input size is, the smaller output size is. Before grinding, the raw material can be crushed by a mini jaw crusher first to make sure a smaller input size.

Another factor should be considered is wear of grinding roller and grinding ring. Once wear occurs, it must have bad influence on output size. To make the distance of grinding roller and grinding ring identical, Raymond mill is optimized and improved into another machine.
