Liyuanheng Raymond Mill Component Advantages

Structural Component Advantages:

1. The skirted belt feeder is equipped with a permanent magnet roller and a frequency converter, ensuring metered feeding, effectively removing metal from the raw material, and protecting the mill.

2. The air-locking feeder eliminates air leakage and ensures stable air pressure

3. The main unit utilizes a gear drive and an internal oil pump, eliminating the need for separate oiling or lubrication stations. A cooler also facilitates installation, commissioning, and maintenance.

The inlet volute observation door features a double-layer structure, with the inner door panel and the entire air duct on a single curved surface, effectively eliminating resistance and reducing system energy consumption.

4. The curved air duct effectively reduces wind resistance and air volume loss, minimizing material blockage.

5. The curved scraper allows the entire surface of the grinding roller to grind the material. The combined scraper head is made of wear-resistant carbide, requiring only the head to be replaced when worn, saving spare parts costs.

The new cage-type powder classifier offers higher screening efficiency, and the pulse dust collector collects excess air and dust, preventing powder spillage, ensuring a clean and environmentally friendly environment.

Grinding Roller + Grinding ring Mn13Cr2Manganese 13 chromium 2: Excellent wear resistance: The synergistic effect of manganese content and chromium can increase the surface hardness from the initial HB210 to more than HB550 when subjected to high stress impact. After a special heat treatment process, it ensures wear resistance and prevents brittle fracture. The wear life is several times longer than that of ordinary steel, which greatly reduces maintenance costs and downtime. / ≥390 / / 213
