MTW Trapezium Grinding Mill Components
This grinding mill equipment is mainly composed of host machine, redactor, separator, fan, cloth dust controller, piping device, integrated device, and electric engine etc. The whole set of equipment is composed of jaw crusher, belt bucket-elevator, feeder machine, storage silo, electrical control tank etc.
MTW Trapezium Grinding Mill Application
MTW European Trapezium Grinding Mill is mainly applied to the powder processing of mineral products in the industries of metallurgy, construction materials, chemical, and mining, etc. This grinding mill can produce powder from various non-flammable and non-explosive mineral materials with Moh’s hardness below 9.3 and humidity below 6%, such as quartz, feldspar, calcite, talcum, barite, fluoride, Xircom, cinder, white lime, cement clinker, activated carbon, dolomite, granite, soft coal, coking coal, lignite, magnesia, chromium oxide green, gold ore, red clay, clay, kaolin, coke, coal Gangue, porcelain clay, kyanite, fluorspar, bentonite, medicinal stone liparite, diabase, pyrophyllite, shale red stone, emeraldite, basalt, gypsum, graphite, carborundun, heat insulating material, etc.
MTW Trapezium Grinding Mill Main Features and Benefits
  1. The bevel gear of our MTW European Trapezium Grinding Mill transmits in a whole, which makes the structure more compact, installation and commission more convenient.
  2. Our MTW European Trapezium Grinding Mill equiped the internal oil pump,which can lubricate the bearings both in main shaft and bevel gear shaft, without connecting any external oil pump or lubrication station.
  3. Our MTW European Trapezium Grinding Mill uses curved wind tunnel repalcing former straight one in the traditional mill.
  4. Sheet of the shovel in our MTW European Trapezium Grinding Mill is easy for change, and cyclone collector in isloted type.
  5. Porthole of our MTW European Trapezium Grinding Mill adopts smooth wind spiral, which also gives the grinding mill a very beautiful appearance.
  6. bevel gear integral transmission: The traditional grinding mill needs decelerator and ratcheting to drive the main shaft that increase the centering difficulty and is easy to bring noise as well as reduce the efficiency. MTW series mills adopt bevel gear integral transmission that compact the whole structure and simplify the installation as well as improve the efficiency.
MTW Trapezium Grinding Mill Working Principle
The main shaft of MTW European Trapezium Grinding Mill connected with the the roller hanger in the top.It is drived by the bevel gear which trabsmits in a whole.The rollers of the grinding mill rotate not just around the main shaft, but also around the grinding ring.Also,rollers can rotate to itself because of friction.Shovels are installed at the bottom end of hanger; materials will be fed into space between rollers and ring to form a material layer when shovels rotate together with rollers. Then The classifier drives the blades in the rotary table through the speed motor to classify the powder.

MTW European Trapezium Grinding Mill Operation and Maintenance
In the operation period , Grinding Mill Machine shall be strict compliance with operating procedures. To achieve constant attention to the grinding mill machine running sound is normal or not, check the lubrication of bearings and bearing temperature is normal, regular checks of the motor temperature and current, check the functioning of the transmission equipment. After the grinding mill outage, check the main bearings, hollow shaft, cylinder, reducer connections and other important components, and wear problems are discovered timely processing.
