Raymond mill machine is a type of mill that can process ore powder and replace ball mills. There are several types of mills on the market including high pressure suspension grinding mills and trapezoid mills that all work on similar principles. For a customer needing to process ore with a hardness of 5.5 to a flour product of 300 mesh at a capacity of 1.5 tons per hour, suitable options would be the 3 r2615 Raymond mill machine or the YGM75 high-pressure suspension grinding mill, with the latter being more suitable due to higher cost performance.
