Fly ball mill Introduction

Fly ball mill for grinding plants, coal cinder field emission of waste, after a ball mill to obtain a fine powder. It is widely used in cement, silicate products, new building materials, refractory materials, fertilizer, black and nonferrous metal and glass ceramics and other production industries of all kinds of ores and other grind-able materials can be dry or wet grinding.

Fly ball mill structures

Fly Ball from the feeding part, discharging Department, Rotary Department, Transmission Division (reducer, small transmission gear, motors, electrical control) and other major components. Cast steel hollow shaft, lined with removable, rotary gear hobbing by casting process, the body inlaid cylinder liner wear, has good abrasion resistance. The machine running smoothly, work reliably.

Fly ball mill works

Be selected according to the size of fly ash, the material from the mill feed end of the hollow shaft mounted cylinder body, when the ball cylinder rotation when grinding due to inertia and centrifugal force, friction force, making the cylinder liner near the posts the board was taken away barrel, when the time was taken to a certain height, due to its own gravity has been thrown down, falling like a projectile, like grinding the cylinder body to the crushed material. Material from the feed device evenly into the mill first warehouse into the compound by the air shaft spiral, the warehouse has ladder liner or corrugated liner, built with different specifications steel ball, rotating cylinder produces centrifugal force to the ball a certain height After the fall, have severe impact on the material and abrasive. The material in the first position reached kibble, after single-layer diaphragm plate into the second warehouse, the warehouse lined with flat lining, the steel ball, the material to further grinding. Powder is discharged through the discharge grate plate to complete the grinding operation.

During the rotation of the cylinder, grinding phenomenon have slipped in during the fall to the material to abrasive action, in order to effectively use abrasive effect on the particle size is large teaching general purpose Ground twenty when the mill cylinder body with diaphragm plate divided into Sec, namely a two-bin, the material into the first position when the ball was crushed, the material into the second position when the end of the material for grinding steel, grinding the material passing from the discharge end of the hollow shaft discharge, small particles of feed material were finely ground, such as when sand II slag, coarse fly ash, mill shell or not to set partitions, a single-chamber tube mill, grinding volume can also be of steel segment .
