MTW Trapezium Grinding Mill

The MTW trapezoidal European version mill is a new type of mill designed based on the high-pressure suspension roller mill. At present, trapezoidal grinding mills are mainly used in mining, building materials, chemical industry, metallurgy, coal, and other industries to grind non-flammable and explosive mineral materials with Mohs hardness below 9.3 and humidity below 6%. It can be adjusted arbitrarily between 30-400 mesh.

MTW Trapezium Grinding Mill Product features


High Efficiency

The integral transmission design of bevel gears results in low energy loss and high efficiency. Compared with traditional mills, the MTW series grinding mill has higher grinding efficiency and lower energy consumption.

Durable and reliable

The important parts of the mill are made of steel, ensuring the durability and reliability of the entire machine. At the same time, the internal thin oil lubrication system also provides a guarantee for the long-term stable operation of the equipment.

Controllable granularity

MTW trapezoidal European version grinding equipment can adjust the grinding fineness as needed to achieve an adjustable and controllable particle size of the finished product. At the same time, the equipped powder selector also has high powder selection efficiency, which can ensure the quality of the finished powder.

Unique design

The grinding roller device not only rotates around the central axis but also revolves around the grinding ring. At the same time, the grinding roller itself also rotates due to friction. This design enables the material to be ground more fully, thus improving the grinding efficiency.

Working principle

What Is The Working Principle Of The MTW Trapezium Grinding Mill

1. Material crushing and transportation: Large pieces of material are first crushed to the required particle size by the jaw crusher, and then the materials are sent to the storage hopper by the elevator. Then, the materials are uniformly and quantitatively continuously fed into the main milling chamber through the vibrating feeder for grinding.

2. Grinding process: In the main grinding chamber, the material is subject to the combined action of the grinding roller and the grinding ring. The grinding roller device not only rotates around the central axis but also revolves around the grinding ring. At the same time, the grinding roller itself rotates due to friction. This movement mode causes the material to be strongly impacted and ground between the grinding roller and the grinding ring, thereby being crushed into fine powder.
