1, energy efficient in the product fineness and motor power being equal, than the jet mill, mixing mill, ball mill high yields more than doubled. 2, long life wearing parts roller, grinding ring made of special materials, in general life of more than one year, the processing of calcium carbonate, the right of life of more than two years. 3, safe and reliable because no rolling bearing and screw grinding cavity, so there is no problem wearing of bearings and seals, there is no screw loosening and destruction of machine problems. 4, clean, environmentally friendly use of pulse dust collector and muffler Raymond mill, greatly reducing the dust pollution and noise, to the country's environmental protection standards. After bluestone after crusher crushing to the desired particle size, the material sent by the hoisting machine hopper ore Raymond mill, and then the feeder will feed into a uniform continuous processing bluestone powder Raymond Mill the grinding machine indoors, due to rotation of the centrifugal force, roller swing outward, pressed on the grinding ring, the shovel blade materials to ultra-fine between Raymond mill roller and grinding ring, because grinding roll Scroll to achieve the purpose of crushing. After grinding powder material is brought into the analysis with circulating air blower machine sorting, fine through coarse material regrinding, qualified powder into the air finished cyclone powder collector through a powder discharge pipe, It is finished. Raymond mill-efficient, Lei Machinery (certification), Raymond mill is provided by Zhengzhou Machinery Co., Ltd. Lei. Zhengzhou Lei Machinery Co., Ltd. (www.hnzljx.net) (www.hnzljx.net) is a leader in Zhengzhou, crushing grinding equipment, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum Limits to meet customer needs. In Lei machinery leadership with the staff warmly welcome all inquiries negotiations to create the better future Lei machinery.
