The right is better, Raymond manufacturers to provide you with better products and services many customers in line to see the model number of Raymond heavy, do not know how to choose a suitable Raymond. Raymond Lei factory machinery to remind you, before you buy Raymond, first set up their use of Raymond mill material feed size of materials, finished product fineness and yield needed to know about that can call us Raymond Lei factory machinery, staff Lei machine according to your needs to provide a more suitable product for you. Large pieces of material must first crushed crusher Before re-entering the mill grinding, milling machine models and types according to the different operating principle is different, so the yield and quality of the finished product also have some differences. The company's main products include Raymond mill series, high pressure hanging roller mill series, high-pressure micro-grinding series, jaw crusher series, impact crusher series, direct impact crusher (sand making machine) series, vibrating screen series, circular vibrating screen series, sand washing machine series, feeder series, ball mill, rotary kiln series, Dryer series, 10 kinds of specifications of the crushing and milling processing equipment, widely used in mining, chemical, cement, metallurgy, building materials, coal, refractories and other industries. Raymond Mill development history of 1925 ECLoesche summarizes the character and structure of the drawbacks of using the first generation of Raymond coal mill zircon sand powder, decided to further improve the structure of raymond grinding mill, we have developed a grinding treatment This is in contrast with 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 roller mill similar device pulls phosphate rock mill, and also fitted with a protective device for children only wear metal contact between the roller and the disc. Also before the mill starts grinding roller mill can be lifted in advance, so you can reduce the starting torque of the motor. Activated carbon Raymond mill in the United States industrial applications, typically used to prepare coal, changes in product fineness of between 250-325 mesh, adjustable work product fineness and yield during operation.
