Super Pressure Trapezium Grinding Mill

TGM series of grinding mill is used to grind all kinds of non-flammable and non-explosive minerals with Moh's hardness below 9.
The main materials are: limestone, cement, clinker, dolomite, calcite, barite, pitch coke, coal, bentonite,etc . The fineness of final product is between 33 and 600 micrometers. The industry powder is widely used in chemical industry, medicine, and building materials, such as cement, cement additive, etc.
Design of TGM series of grinding mill has changed roller structure of traditional grinding mill, so life of roller and ring is longer, efficiency is higher. TGM series of grinding mill has higher economy than ball mill and Raymond mill. Recently, TGM series of grinding mill is mainly used to crush coal as slurry fuel in the furnace, which reflecting higher economy again. In Russia, our TGM mill grinds cement clinker and blast furnace slag mixture successfully, which solves several technical problems in the grinding industry. In India, TGM mill is widely used to grind pitch coke, kaolin, feldspar, calcite, bentonite, etc. Many Chinese customers use TGM mill in the cement additive industry.

Working Principle:

Large materials are crushed by Jaw crusher to the needed sizes firstly, then the materials are elevated to storage hopper by bucket elevator, third, the materials are fed into the grinding chamber for grinding by vibrating feeder equably and continuously. The powder after grinding goes upwards together with the airflow, after separating by powder separator, those which can meet the fineness requirement enters into the cyclone powder collector through pipe together with the airflow, and then discharged from the discharge valve as final products. The airflow is sucked into centrifugal blower through wind recycling pipe at the upper part of cyclone powder collector. The mainframe is driven by the speed reducer through the central axis in the mill. The quincunx stand connected with the upper part of central axis, at the quincunx stand, rollers are set and by which the vibrating pivot formed. Below the quincunx stand and rollers there is shovel system. Materials are fed into the space between rollers and shovels when they are turning, and then be grinded by the pressure produced when rollers are turning, thus powder is made.
