TGM Trapezium Mill

Products:

TGM Trapezium Mill,

Material:

Cement, coal, fly ash, putty powder, gypsum powder, limestone, kaolin

Application:

Cement, Coal, power plant desulfurization, metallurgy, chemical industry, non-metallic mineral, construction material, ceramics.

Advantages:

The diameters of each part of rollers and rings are different, the upper part is big and the lower part is small, then they formed a trapezium form. This form can reduce materials’ sliding speed downwards and prolong the grinding time for materials, thus the grinding efficiency is increased.; the pressing springs have the functions of balancing and pressure increasing; the flexible connection can make the mill stable, decrease the shocking and avoid sympathetic vibration; high density powder separator impeller decreases the air resistance and increases powder collecting fineness and capacity; the efficiency of energy saving and high efficient centrifugal blower is as high as 83%.

Overview:

TGM Super Pressure Trapezium Mill adopts five proprietary technologies including trapezium working surface, flexible connection, roller linked pressure boost, etc. Because of advantages of large capacity and long service life, this machine has won many praises from customers.

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.
