MTW Trapezium Mill

MTW Series trapezium mill is the latest grinding mill, which is developed by our company's experts based on 10 years' R&D on grinding machine. It owns many independent patents property, such as overall prick gear drive, internal thin oil lubrication system, arc-shaped air duct. All of these make it leading the trend of the milling industry in the world.

Features

1. Exquisite appearance.
2. The whole bevel gear transmission.
3. Internal thin oil lubrication system.
4. curved duct.
5. Curved surface shovel with exchangable blade.
6. Isolated cyclone collector.
7. No resistance inlet volute (small observation door without vortex).

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.

the rivet hole prone to fatigue cracks, the entire root available unused new electrode welding repair cracks, but at the center of symmetry axis impeller carried the rest of the crack at the welding electrode to stay in the area, and then a new welding repair cracks symmetrical rivet holes, as long as the rest of the electrodes when welding finished with symmetrical rivet repair the rest of the electrodes, welding up to ensure equal weight
