Pin Mill is suitable to grind crystal and brittle materials. The output fineness can be changed by replacement of the filtering-screen and adjustment of the rotor speed. With a wild range of applications to a variety of products, and the features of optional grind disc replacement for proper materials. Especially, this machine is easy to clean (water rinse) and do maintenance.

  • Processes a wide range of raw materials. Durable, low-waste design.
  • Easy to operate, saves time & power, highly efficient.
  • Durable components are easy to replace & clean.
  • Fineness: 20~150Mesh. (data is for reference only & may vary according to raw material)


Ideal for pulverizing any materials (except highly oily or sticky ones). Due to the variety and interchangeability of internal components, this equipment has wide production adaptability, ranging from granular material to super-fine particles. Turnkey system is designed to prevent contamination of materials, increase efficiency, lower manpower requirements and maintain material quality.


Raw material is fed into the grinding chamber from the feeding hopper.

The first grinding is a shearing force created by the cutting impact of the inner rotor and stator.

After filtrating, any remaining coarser powder will be ground in the third grinding until it passes through the screen mesh.

The finished product is discharged from the rotary valve.
