Raymond Mill

product introduce:The ramon grinder is the first generation of dawn heavy industries.It is suitable for the preparation of fine powder of raw mineral, gypsum and coal.This machine covers a small area, low investment cost and low consumption.

Applications: Cement, coal, desulphurization power plants, metallurgy, stone industry, non-metallic minerals, building materials, ceramics, etc.

The ramon mill is also known as the ramon mill.The equipment is more efficient than ball mill, low energy consumption, small footprint and less one-time investment.The grinding roller compacts the grinding ring under the action of centrifugal force, so when the grinding roller and grinding ring wear to a certain thickness, it will not affect the output and fineness of the finished product.The long replacement cycle of grinding roller and grinding ring eliminates the shortcoming of short replacement cycle of vulnerable parts of centrifugal grinder.Mainly used for barite, calcite, potash feldspar, limestone, talc, white stone, gypsum, etc.


1、The finished powder has uniform fineness and the sieve rate is 99%, which is difficult to be possessed by other grinding equipment.

2、The important parts are made of high quality steel.Wear-resistant components are made of high performance wear-resistant materials.

3、Adjust the length of the high pressure spring to maintain constant grinding force between the roller and the ring.

4、Adopt efficient dust removal equipment and rigorous parts processing technology.

Working Principle

Raymond mill principle of work is in the tight roll grinding ring under the centrifugal force, the shovel shovel grinding roller and grinding ring material, this material under the action of broken into powder, and then in the role of the fan to the powder to blow up by analyzing the machine, to fulfill the requirements of fineness of material through analysis machine, cannot achieve the required return to continue to grinding, grinding chamber through the analysis of the material into the cyclone to collect.The waste gas is separated into powder by industrial press.
