After bluestone after crusher crushing to the desired size, the material sent by the hoist storage hopper 3015 Raymond mill, and then the feeder will feed into a uniform continuous processing bluestone powder Raymond Mill hosts Raymond mill grinding room 3016, due to the centrifugal force, roller swing outward rotation, pressed on grinding ring, shovel blade materials sent between roller and grinding ring, due to the rolling mill rolls to achieve smash purposes. After grinding the powder material is brought into the analysis with circulating air blower machine sorting, fine through coarse material regrinding, qualified powder into the air cyclone powder collector finished by powder discharge pipe 6R Raymond mill, is finished. Centrifugal ultra-fine milling machine is suitable for barite, calcite, limestone, kaolin, bentonite, marble, gypsum, refractories, quartz, glass, ceramics and other hardness less than 9.3 Raymond mill, humidity 6 % or less of the high processing mineral powder, particle size between 80 mesh -1500 mesh of arbitrary regulation. Ultrafine mill technical advantages: 1. wear high material utilization, Raymond service life four times; 2. Processing sand, significantly higher than the effect of other mills; 3 is a highly efficient desulfurization plant equipment; 4. As can pre-grinding before milling milling efficiency increased by 50%; 5. Mainly used for a variety of brittle materials can be crushed, Mohs hardness of less than 9 following materials pre-grinding. 3R Raymond mill, the Lei machinery (certified), Raymond mill is provided by Zhengzhou Machinery Co., Ltd. Lei. Lei Zhengzhou Machinery Co., Ltd. (www.hnzljx.net) (www.hnzljx.net) is a leader in Zhengzhou, crushing grinding equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum limits to meet customer needs.
