Raymond mill
BH Raymond Mill is a new-generation, highly efficient closed-circuit fine grinding equipment, making it the optimal choice for grinding various materials into ultrafine powder.
Operating within a sealed system, this grinding mill ensures optimal efficiency and precise particle control.
The synergistic collaboration between the analyzer and fan enables the mill to meet diverse requirements with accuracy and reliability.
BH Raymond Mill is primarily used for the powder processing of mineral materials in industries such as metallurgy, building materials, chemicals, and mining.
It can effectively grind non-flammable and explosive materials with a moisture content below 6%, including marble, phosphate ore, slag, fly ash, coke, gypsum, and more.
2) With a pass rate of 99%, BH Raymond Mill surpasses other grinding mills in terms of efficiency.
3) The main transmission system employs a sealed gear unit and pulleys, guaranteeing stable operation and reliable performance.
4) Premium-quality cast steel materials are used for key components, ensuring durability and longevity.
5) The centralized control of the electrical system achieves a high degree of automation, eliminating the need for on-site personnel in the control room.
6) Equipped with a highly efficient dust collector, the mill prevents dust leakage, maintaining a clean working environment.
1) Raymond Mill produces finer particle size of powder.
2) Raymond Mill produces more uniform powder compared to ball mill.
3) Raymond Mill has a smaller footprint than ball mill.
4) Raymond Mill is suitable for processing non-metallic minerals with Mohs hardness below 7, such as gypsum, limestone, calcite, talc, kaolin, coal, etc.
