small ball grinder

small ball grinder is the material being broken, and then smash the key equipment. It is widely used in cement, silicate products, new building materials, refractory materials, chemical fertilizer, black metal, nonferrous metal, glass, ceramics etc. industry production of all kinds of ores and other materials may be grinding of dry or wet grinding. According to different ways of discharge, can be divided into lattice type ball mill and overflow type ball mill two.

working principle

This machine is a horizontal rotating device, outer gear, two warehouses, lattice type ball mill. Material from the feed device feeding hollow shaft screw evenly into the mill first storehouse, the warehouse has stepped lining board or corrugated liner, built in different specifications of steel balls, the cylinder rotation, the centrifugal force generated the ball to a certain height after falling, the material to produce pounding and grinding. The material in the first position to coarse grinding, the single compartment into the second warehouse, the warehouse linedwith flat lining, steel ball inside, the material to further grinding. Powdered thedischargegratedischarge, finish grinding operation.

Structural characteristics

This machine consists of feeding and discharging, turning part and driving part (reducer, small gear, motor, electric control) and other major parts. Hollow shaft with steel castings, the liner is detachable, the rotating big gear adopts casting hobbing, cylinder body inlaid with wear-resistant liner, with good abrasion resistance. The machine operates smoothly, reliable work.

Note: according to the material and mineral, can choose the dry and wet Grate Ball mill.

technology

The barrel body crushed ore and steel balls in the rotating cylinder body by friction force and the centrifugal force is lining board to a certain height due to the action of gravity, dropping and cascading ore in grinding and impact gradually disintegrated. The crushed ore discharging portion of the exhaust tube. Discharge of minerals in the spiral classifier by grading the qualified products, coarse sand through the combination of the feeder back to ball mill to grinding. Feeder continuous and uniform feeding ore by the combination of the feeder continuous evenly into the ball mill, by grinding the material flowing from the ceramic mill discharge.
