Characteristics, maintenance and operation process of lithium manganate jet mill

Lithium manganate jet mill is based on the design of traditional fluidized bed mill, combined with the unique self split classification technology of Umico, which makes its performance far superior to that of fluidized bed jet mill at home and abroad. Lithium manganate jet mill is also widely used in chemical industry, mining, abrasives, refractories, battery materials, metallurgy, building materials, pharmaceuticals, ceramics, food, pesticides, feed, new materials, environmental protection and other industries, as well as various dry powder materials for ultra-fine crushing, breaking and particle shaping

Maintenance of lithium manganate jet mill 1. During production, the temperature rise of the bearing must be checked frequently. When the temperature rise exceeds 50 ℃, the machine should be shut down for inspection to find out the cause and remove the fault. 2. When the new machine is running, the drive belt is easy to stretch, and the proper tightness of the belt should be adjusted to ensure the working life of the belt. 3. Wearing parts shall be checked frequently and replaced timely to ensure production quality and production volume. 4. The blade and lining ring shall be regularly checked for wear. If the productivity decreases and the particle size becomes coarse after wear, they shall be replaced immediately. 5. The main engine and the graded flow bearing are lubricated with grease, and No. 2 special grease, 265-295, is used. 6. The grease change period of the bearing is 2000 hours, and the filling amount of the grease is 1/2 (upper measurement) or 3/4 (lower measurement) of the space in the bearing cavity. Do not fill too much grease, otherwise the bearing temperature will be too high. 7. The grease change period of the screw feeder is 4000 hours. Add ordinary calcium base grease< Br/>Features of lithium manganate jet mill:
1. Strong crushing capacity, low energy consumption, and small product fineness< Br/>2. The crushing space is large. The high strength wind pressure generated when the turbine is running can not only improve the production capacity, reduce the over crushing phenomenon, but also effectively avoid the deposition and blockage of the screen mesh caused by materials during the crushing process. The high strength wind pressure can also carry away the heat generated in the crushing chamber in a large extent< Br/>3. Because shearing is strengthened, the crushing capacity of fibrous materials is higher than that of ordinary equipment< Br/>4. The screen is easy to install, and the ding position is reliable, all of which are plug-in. The service life is much longer than that of the ring screen< Br/>5. The built-in motor is designed to reduce the center of gravity of the machine and effectively reduce equipment noise< Br/>The material is conveyed to the crushing chamber of the host machine by the feeding device. The material is crushed by mutual impact, collision, friction, shearing and extrusion between the material and high-speed rotary devices and particles. The crushed materials are separated from the fine and coarse powders by the grading wheel. The coarse powders flow into the crushing chamber for grinding again, and the purified gas is discharged by the induced draft fan< Br/>Operation process of lithium manganate pneumatic crusher:
1. First open the door of the collection box of the mechanical crusher, tie a special cloth bag at the material port, and then close the door of the collection box< Br/>2. Screen shall be selected and installed according to the process requirements of mechanical crusher< Br/>3. It is also necessary to check whether the materials to be crushed by mechanical crusher need to be pretreated< Br/>4. First turn on the switch of the fan, then turn on the switch of the motor. After the equipment operates normally with no load, add materials. The feeding speed is adjusted according to the degree and fineness of friability and crushing of materials< Br/>5. Stop feeding at the end of crushing operation or before stopping the machine, and let the mechanical crusher run for several minutes until there is no residue in the crushing chamber< Br/>6. After turning off the motor switch of the mechanical crusher, open the door of the collection box and take out the materials for use< Br/>7. If the amount of crushed materials is large, the mechanical crusher can be operated repeatedly until all materials are crushed< Br/>8. When the operation of the mechanical crusher is completed, all power switches need to be turned off< Br/>9. Check the intactness of the mechanical crusher equipment and components for abnormalities< Br/>The lithium manganate air flow mill produced by Qingdao Youmingke is MQW-400, with high processing precision, high efficiency, good stability, and high popularity in the industry.
