Potassium feldspar, generally called orthoclase, is red, yellow, white and other colors. It belongs to the monoclinic crystal system and has a Mohs hardness of 6. It is a water-insoluble potassium resource with high potassium content, wide distribution and large reserves. Potassium Feldspar has the characteristics of low melting point (1150±20℃), long melting range and high melt viscosity. It can be divided into orthoclase, plagioclase, and striped feldspar series.

| Model | Vertical mill or Raymond mill | Ultrafine roller mill or Vertical ultrafine mill |
The material is crushed by the crusher to the fineness that can enter the mill(15mm-50mm).
The crushed small pieces of material are sent to the storage hopper through the elevator,and then sent to the grinding chamber of the mill evenly and quantitatively through the feeder for grinding.
Through classification, the coarse powder will return to main mill to grind again.
The powder that meets the fineness enters the dust collector through the pipeline with the air flow for separation and collection, and the collected finished powder is sent to the finished product silo by the conveying device through the discharge port, and then is packaged uniformly.
