The Raymond Mill is one kind of the grinding machines, ii is use to grinding the materials which are non- inflammable and non-explosive with the hardness below 9.3Mohs and moisture level less than 6%,such as ores ceramics ,clinker, slag ,coal and so on .

We designed our Ultra-fine Raymond mill by several decades production experiences and absorbing the up to date technology home and abroad.

Compared with the common Raymond Mill, it can realize a more smaller product size

Working Principle of Raymond mill

Large materials are crushed by Jaw crusher to the needed sizes firstly, then the materials are elevated to storage hopper by bucket elevator, third, the materials are fed into the grinding chamber for grinding by vibrating feeder equably and continuously. The powder after grinding goes upwards together with the airflow, after separating by powder separator, those which can meet the fineness requirement enters into the cyclone powder collector through pipe together with the airflow, and then discharged from the discharge valve as final products. The airflow is sucked into centrifugal blower through wind recycling pipe at the upper part of cyclone powder collector. The mainframe is driven by the speed reducer through the central axis in the mill. The quincunx stand connected with the upper part of central axis, at the quincunx stand, rollers are set and by which the vibrating pivot formed. Below the quincunx stand and rollers there is shovel system. Materials are fed into the space between rollers and shovels when they are turning, and then be grinded by the pressure produced when rollers are turning, thus powder is made.

The turbine classifier achieves a more accurate classification, resulting in a steeper particle size distribution. The product size, depending on application, ranges from 80 mesh to 1000 mesh
