Tumbling Mill

The Description and Application of Tumbling Mill:

Tumbling mill can grind many kinds of ore and other materials, thus it is widely used in powder-making production line including cement, silicate, new-type building material, refractory material, chemical materials, ore dressing, ferrous metal and non-ferrous metal, glass ceramics industries etc.

The Processed Materials of Tumbling Mill:

Limestone, calcite, barite, dolomite, potassium feldspar, marble, talcum, gypsum, kaolin, bentonite, medical stone, rock phosphate, manganese ore, iron ore, copper ore, gold ore,quartz, active carbon, carbon black, ceramic, coal, etc.

Tumbling mill is mainly composed of feeding part, discharging part, rotary part and driving part which includes reducer, small drive gear, electrical machine and electronic control. The hollow shaft uses steel casting, the inner lining can be dismantled and changed, and the rotary rack wheel uses casting gear hobbing and inside the cylinder there is wear-resisting lining board which has fine abrasion performance. This machine has stable operation and reliable performance.

According the materials and discharging method, Tumbling mill can be divided into dry type Tumbling mill and wet type lattice ball mill.

This machine is a horizontal type cylinder rotary device and outside the cylinder there is drive gear which drives the cylinder to rotate during the working process. Materials spirally and evenly go into the first cabin of the grinding machine through the feeding hollow shaft from the feeding device, and inside the first cabin, there are ladder lining boards or ripple lining board in which there are many steel balls with different specifications. The cylinder rotates and produces eccentric force to bring the steel balls to a certain height, and then the steel balls will fall down to impact and grind the materials. After being coarsely ground in the first cabin, the materials will go through the single-layer partition board and into the secondary cabin in which there are flat lining board, and in the lining board there are steel balls to further grind the materials. Finally the powdery materials will be discharged from the discharging grating bar to complete the powder grinding process.
