LM Grinding Mill
LM series vertical milling machine, which is developed and launched by GM, sets medium crushing, drying, grinding, classifying and other functions as a whole, being the ideal equipment in the grinding industry.
Features
Low running costs It adopts the technology that vertical roller grind material directly on the disc, with low energy consumption; for the roller is not contact with the disc directly in the work, and the roller and liner are made by quality materials, it is of less wear and long life. Simple and reliable operation Its automatic control system can reach remote control, which is easy to operate; there is the device to prevent roller sleeve contact with disc liner directly, and avoid the destructive impact and severe vibration; we can turn the rotating arm by repairing fuel tank, replace the roller and liner are more convenient, which can reduce the downtime. Energy conservation and environmental protection It features small vibration, low noise, and sealing device as a whole, and the system also works with no pressure and dust spills.
Repair method
each bearing are using a No. 1 MOS2 grease or ZM - 2 sodium grease lubrication, roller bearing refueling once every two classes, the host bearing refueling once every four classes, blower bearings refueling once every month. Bearing temperature rise to a maximum of 70 degrees Celsius, was found to be breaking the bearing overheated bearings and bearing chamber cleaning accessories such as cleaning once.
if the head of the rivet is worn impeller, the impeller body by pressing and welding with the welding of the hub, so that the wear of the head of the rivet back to the normal state.
