At the same production value and the same demand, we can distinguish the difference between the feed size, the fineness of the finished product and the volume and footprint of the equipment: firstly, the high pressure micro-powder is only suitable for feed sizes below 20 mm, three rings. The medium-speed mill can only grind the material with the feed size of 10 mm; the fineness of the three-ring medium-speed mill is finer than that of the high-pressure fine powder; the high-pressure micro-fine Raymond mill is more than the third ring The micro-fine Raymond mill has a small footprint. The larger the size of the Raymond mill, the more troublesome it is when handling. The larger the plant area, the more the investment cost, so the high output value is high.

The micro-powder Raymond mill has a smaller investment than the three-ring micro-powder Raymond mill. The power of the main engine of the high-pressure micro-powder Raymond mill is usually between 18.5 and 37 (unit: kw), and the power of the fan is usually between 15 and 30 (unit: kw). The power of the main body of the three-ring micronized Raymond mill is usually between 37-90 (unit: kw), and the power of the wind turbine is usually between 30-75 (unit: kw). Therefore, the high-pressure micro-powder Raymond mill is more energy efficient than the three-ring micro-fine powder Raymond mill.
