Fly ash ball mill for grinding coal ash in flyash production line

Fly ash ball mill is the key equipment to grind after the material broken. It is widely used in cement, silicate products, new building materials, refractory materials, chemical fertilizer, black and non-ferrous metal mineral processing, glass ceramics and other production industries, all kinds of ore and other abrasive materials for dry or wet grinding. Ball mill is suitable for grinding various ore and other materials, is widely used in mineral processing, building materials, chemical and other industries.

The fly ash ball mill is composed of feeding part, discharging part, revolving part, transmission part (reduction box, small drive gear, electric motor, electric control and so on. 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 is stable and reliable. 
The main body of the fly ash ball mill comprises cylinder body, lining which is made of useful wear-resistant material, and bearing bearing cylinder body and bearing, and driving part, such as electric motor, driving wheel, belt wheel, triangle belt, etc.

Fly ash ball mill application:
Fly ash ball mill is applied to fluorite, calcite, talc and kyanite, barite, marble, diatomite, barite, gypsum, alum stone, graphite, phosphate rock, potassium and so on. The fly ash ball mill is mainly used in processing Mohs hardness 9.3 below grade, humidity below 6% of all non inflammable and explosive mineral materials processing, in the metallurgy, building materials, chemical industry, mines, highway construction, water conservancy and hydropower industry is widely used.

According to the granularity of the abrasive material, and material from the ball mill feed end of the hollow shaft into the cylinder body, ball mill rotating cylinder grinding body due to inertia and centrifugal force, the friction force, it posts near the cylinder liner cylinder away, was taken to a certain height when being thrown, due to its own gravity, the whereabouts of the grinding body like a projectile to the cylinder body materials crushed. Material from the feed device into the compound empty shaft spiral evenly into the mill first warehouse, the warehouse there are 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, the thump and grind the material. The material in the first warehouse, coarse grinding by monolayer partition panel into the second position, the warehouse lined with flat lining with steel balls, the material further grinding. Powder discharged through the discharge grate plate to complete the grinding operation. Cylinder in the process of turning, grinding body slipping phenomenon, to the material to the grinding action in the slipping process, in order to effectively use the abrasive material granularity teach general 20 mesh pulverized when the mill body cylinder with compartment plate separated Sec dual positions become material into the first positions when they were crushed by the steel ball, the material into the second position when the steel end materials grinding finely ground material from the discharge end of the hollow qualified shaft discharge small particles of feed material pulverized when, as sand the 2nd slag, coarse fly ash, mill shell may from time to set up partitions, a single silo mill grinding volume of the steel segment.
