Powder metallurgy is a process technology for manufacturing metal materials, composites and various geometric products through the preparation of metal or non-metallic powder or metal powder (or non-metallic powder) as raw materials, forming and sintering.

Compared with the traditional technology, it has the advantages of energy saving, material saving, labor saving, environmental protection, near net forming, personalized, good consistency and so on.

Its advantages make it become the key to solve the problem of new materials, which plays an important role in the development of new materials, and belongs to the sunrise industry of modern industrial development. Hard carbide this industry closed loop airflow grinding and closed loop graders are very suitable.
