Applicable Scope

Working Principle: In the rotation of the inner has some certain number of grinding medium—steel ball, when rotating parts rotate, steel ball in the effect of The centrifugal force and friction force caused by rotation of the cylinder brings the steel ball to a certain height, impact and grind the the materials .then fallen down to the bottom by gravity.

Technical Features

Technical feature:

. Drive type:

(1) asynchronous motor +reducer+ small gear+ large gear

(2) Synchronous motor+ air clutch + small gear+ large gear

Supporting type:

(1)Generally use both ends of the static and dynamic pressure bearing support, using a completely enclosed self-aligning 120°line contact “rocker” bearing , to match with high and low pressure lubricating oil station.

(2) energy-saving: both ends of rolling bearing supporting

Main bearing temperature measurement: adopting special platinum thermal resistance temperature sensor, temperature measurement time is short ,high sensitivity, and automatic monitoring. ,avoid the bush-burning phenomenon.

• The key processing technology

（1）The Cylinder adopts automatic welding, ultrasonic testing, the whole annealing and large –scale special machine once installed card processing.

（2）The end caps adopt optimal design, special cast steel, whole annealing. Once installed card processing.

（3）Hopper ,hollow shaft such as static and dynamic combination part fitted with special seals to ensure that its no leakage ,no slurry leakage.

Large open gear, equipped with a reliable sealed gear cover with automatic lubricating device for dry oil..
