Ball Mill

Ball mill is the key equipment for re-crushing, it is widely used for dry or wet powder

grinding operation of ore grinding before dressing ferrous and non-ferrous metal, raw

material or finished product of cement, chemical industry, novel construction material,

refractory material, etc. The machine is composed by feeding part, discharging part,

turning part and driving part (reducer, small driving gear, electric motor and electric

control).The quill shaft adopts cast steel part and the liner is detachable. The turning

gearwheel adopts casting hobbing process and the drum is equipped with wear-resist-

ant liner, which has good wear-resistance. The machine is with stable and reliable work-

ing condition. Moreover, according to different materials and discharging methods,

there are dry ball mills and wet ball mills for choice. our company owns the leading

technology and rich practical experience, and we can offer 360 º service, and leave

you from any worry.

General working principle: This machine is a skeleton pattern ball mill with horizontal

cylindrical turning gear, driving by outer gear and two hoppers. The material goes to the

first hopper after the spiraling by the quill shaft from the feeding equipment. The hopper

has ladder sheathing or corrugated sheathing with steel balls inside, which will fall under

the effect of centrifugal force by barrel turning to ram hard and grind material. After the

kibbling in the first hopper, by monolayer partition panel, the material will enter the second

hopper, which has plane scale board with steel ball inside to grind material. The powder

material will be discharged from the grid plate to finish the grinding.

Dry or wet ball mill will be optional according to material and ore-discharging mode. Wet

Ball Mill’s Working Principle This machine is a horizontal drum-like rotary unit, its outside

is driven along the gear, inside the drum is medium (steel ball),material is fed through the

feeding end of the drum, by following the rotation of the drum, the medium falls down after

being lifted to a certain height by the centrifugal force from drum movement, heavily bang

on the material due to irregular slide and rolling. Grinding thus comes into being among the

medium, material and drum, so as to grind the material. The material is continuously fed,

dynamic granularity level difference is thus occurred between the feeding and discharging

ends, fine material flows out of the drum slowly and gradually, grinding.
