According to new German technology, MTW Heavy type Trapezium Mill is designed which is possess of many creative designs including bevel gear overall drive, dilute oil lubrication system and hanging type cage classifier. With mature technology and advanced transmission, this machine can satisfy customers’ requirements about productivity because its capacity ...

First, raw material should be crushed by the jaw crusher to the size specified, and then the crushed stuff is elevated into a hopper from which the stuff is loaded, through the vibrating feeder, evenly and continuously into the grinding chamber for power-processing. After this, the ground stuff is carried by the air into the separator for screening. The fine powder are blow into the cyclone collector and are poured out through the output-powder valve as the final products and the rough stuff after the screening will be recycled back into the grinding chamber for regrinding. The set's airflow system is closely sealed up and circulated under condition of negative pressure.


1.Advanced transmission
Bevel gear overall transmission, transmission ratio is accurate, less transmission chain, energy loss, significantly improved performance.
2.Use thin oil lubrication
Spindle drive system, fan drive system are thin oil lubrication, oil change period of about 4 months, long oil change intervals, low cost, less maintenance frequency.
3.Using a new type of hanging cage separator
The use of a new type of hanging cage separator, the election of high efficiency, high precision; variable frequency control, adjustable particle size control.
4.Advanced technology, low operating costs
From Germany's new technology, the use of seven core patents. High efficiency, low operating cost, high quality pendulum mill products.
5.Energy saving and environmental protection
Environmental certification through industrial products to meet the national environmental requirements.
6.Bevel gear overall drive. Transmission chain is less but transmission ratio is accurate. Energy consumption is reduced by 20-30%.
7.This machine adopts internal thin oil lubrication system to get better lubrication effect. The oil exchange cycle is long and it is easy to maintain.
8.This machine adopts new hanging type cage classifier, which can improve classifying efficiency effectively. There is frequency conversion control and the output size of final products can be regulatable.
9.There are 7 core patents and it adopts new German technology. MTW Heavy type Trapezium Mill has been high-quality products because of high efficiency and low running costs.
10.This machine has got environmental protection certification in industrial products, and it can meet the demand of environmental protection.
