MTW Trapezium Mill Has A Wide Range Of Application

This MTW trapezium mill is mainly applied to the powder processing of mineral products in industries of metallurgy, construction, chemistry, and mining etc.

MTW Series trapezium mill

trapezium mill

MTW series trapezium grinding mill is mainly applied to the powder processing of mineral products in industries of metallurgy, construction, chemistry, and mining etc. The grinding machine can produce powder from non-flammable and non-explosive mineral materials, such as barite, limestone, quartz, calcite, granite, porcelain clay, basalt, gypsum etc. As a world famous trapezium mill manufacturer, Zenith grinding mill has widely applications in powder processing. Our grinding mill has been greatly welcomed in the world market. We could provide cutting-edge crushing and grinding solution for mining industry. If you are interested, please feel free to contact us for more information.

MTW Series trapezium mill is the latest grinding mill, which adopts many advantages from numbers of mill all over the world, such as trapezium's working surface, flexible connection, roll linked pressure boost, etc. It owns many independent patents property, such as overall prick gear drive, internal thin oil lubrication system, arc-shaped air duct. Now a number of customers are fond of it for its incomparable features. All of these make it leading the trend of the milling industry in the world.

Product advantages

  • The bevel gear transmits in a whole, which makes the structure more compact, installation and commission more convenient;
  • The internal oil pump can lubricate the bearings both in main shaft and bevel gear shaft, without connecting any external oil pump or lubrication station;
  • Former straight wind tunnel in the traditional mill is replaced by curved one;
  • Sheet of the shovel is easy for change, and cyclone collector in isolated type;
  • Porthole adopts smooth wind spiral, which also gives the mill a very beautiful appearance.

Repair method

  1. 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.
  2. 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.
  3. 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
