Which parts of the cyclone are easy to wear?

The wear of heavy medium cyclones is mainly divided into three types – cutting wear, fatigue wear and corrosion wear.

1. Cutting wear: During the coal preparation process, materials will rotate at high speed in the cyclone. Materials such as coal gangue with large particles and heavy weight will form an outer spiral and spiral downward along the inner wall of the cyclone. These materials will Causes cutting wear to the inner wall of the cyclone.

2. Fatigue wear: When liquids and materials continue to rotate at high speed in the cyclone, deformation and stress will be generated at the contact points. This process continues, causing the particles on the inner wall of the cyclone to peel off, penetrate from the surface to the inside, and gradually expand. Wear hazards.

3. Corrosion and wear: During the coal preparation process, the inner wall of the cyclone will undergo chemical and electrochemical reactions with certain substances in the material, including oxidation reactions, cavitation wear caused by bubbles in the material, acid and alkali corrosion of the material itself, etc.
