Raymond Mill development history of 1925 ECLoesche summarizes the character and structure of the drawbacks of using the first generation of Raymond Raymond coal mill machine, we decided to further improve the structure of raymond grinding mill, a grinding processing and the development of this Instead of the mill, called Improved Raymond. The main structure is characterized by ring grinding bowl rotation, the roller using a mechanical spring load pressure increased grinding force, the material is fed from the center of the ring by a rotating grinding bowl centrifugal force into the roller. Grinding roller shaft is fixed on a one-way movable arm, each arm can be adjusted by the grinding force of the control spring. This improved ventilation systems Raymond has positive and negative pressure blowing straight in two ways. This type of raymond mill patent soon to be US Combustion Engineering (Combustion Engineering) purchased. Because there are still Improved Raymond roller mill ring problems, although a slight increase in the roll diameter, but not grinding force increases. Later, the US subsidiary Combustion Engineering of Raymond and on this basis, developed a new generation of Raymond, called VR mill. In many respects this Raymond Loesche mill structure is now similar. It is worth noting that it is different from Loesche grinding tapered roller and flat disc, while using a cylindrical roller and grinding disc surface tilt angle of 15 degrees with use. Roller has in the inspection and maintenance and Loesche mill roller pulls a similar device, and also fitted with a protective device for children only wear metal contact between the roller and the disc. Also before starting the roller mill can be lifted ahead of time, so you can reduce the starting torque of the motor. Raymond industrial applications in the United States, usually used to prepare coal, changes in product fineness between 250-325 mesh Raymond, adjustable work product fineness and yield during operation. Raymond mill major role in calcium carbonate production line in China is a rich in mineral resources such as phosphate rock, barite, gypsum, calcium carbonate, limestone. Raymond 3016 with the development of science and technology, we have a number of machinery and equipment by these processing and utilization of mineral resources. Today we use it as calcium carbonate in our lives. Calcium carbonate in the rubber industry, plastics industry, paint industry, water-based paint industry, paper industry, construction industry, building materials industry has been so widely used. Calcium carbonate is divided into light and heavy calcium carbonate, is through a series of ore limestone, calcite, talc, etc. can be obtained by grinding processing calcium carbonate powder. With the booming construction industry in China, the demand for building materials has been a steady increase trend, or whether it is light calcium GCC, in the building materials industry are important materials Raymond mill, future demand for calcium carbonate powder the amount that would be great. Calcium powder mill production equipment used, because the required fineness of different calcium carbonate powder production equipment is correspondingly different, 400 mesh calcium carbonate powder Raymond Mill main choice of different applications, 425 mesh must pay attention to when selecting more than calcium carbonate superfine powder mill, when you buy distinguish calcium carbonate powder production equipment, to avoid the wrong choice and delay subsequent production. Raymond mill full production line include: crusher, elevator, hopper, electromagnetic vibrating feeder, Raymond host, analysis machine, reducer, fans, filter, connecting pipes, etc., are relatively complete a sets calcium carbonate equipment.
