Should We Choose Raymond Mill or Vertical Roller Mill For Aluminum Powder Processing?

Aluminum powder, commonly known as silver powder, is a kind of silver metallic pigment. It is crushed into scaly powder by adding a small amount of lubricant to pure aluminum foil, and then polished to become our applicable aluminum powder.

Aluminum powder has the advantages of light weight, high floating force, strong covering force and good light and heat reflection performance. After treatment, it can also become non floating aluminum powder. Aluminum powder can be used to identify fingerprints and to make fireworks.

Aluminum powder is widely used and in great demand. Since the 19th century, it has been produced by a single ball mill. However, with the development and upgrading of modern mills, aluminum powder can also be processed and produced by Raymond mills, ring roll mills or vertical mills.

Production process of aluminum powder

1. Drying
   Aluminum powder aluminum powder is dried by drying machine or heating air to mill according to water content.
2. Feeding
   The small aluminum powder material after aluminum powder grinding is sent to the hopper through the elevator, and then sent to the grinder room evenly and quantitatively through the feeder for grinding.
3. Grinding classification
   The fine aluminum powder after grinding is graded by the grading system, and the unqualified fine powder is graded by the classifier and returned to the vertical mill host for regrinding.
4. Collect finished products
   The powder conforming to the fineness enters the dust collector along with the air flow through the pipe for separation and collection. The collected finished product powder is sent to the finished product warehouse through the conveying device, and then packaged by the powder tanker or automatic packaging machine.

Vertical mill or Raymond mill for aluminum powder mill

Some manufacturers of aluminum powder grinding production line adopt vertical aluminum powder mill, aluminum powder micro powder mill, aluminum powder ultra-fine powder mill and aluminum powder Raymond mill. The selection of aluminum powder mill shall be based on the fineness of aluminum powder. Secondly, it shall be selected by referring to the output of aluminum powder and combining its own investment cost.
