Overview of conical ball mill
According to different ways of ore discharging, ball mill is divided into grate ball mill and small ball mill factory , which is currently the most common ore grinding machine. Overflow ball mill is the key equipment for grinding after the crushing process, and it is widely used in the manufacture industries such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics. Overflow Ball Mill are generally used to grind materials with 1/4 inch and finer to the particle size of 20 to 75 microns. In order to achieve reasonable efficiency with ball mills, they must be operated in a closed system with oversize material continuously being recirculated back into the mill to be reground.
The machine is composed of feeding part, discharging part, turning part and driving part (reducer, small driving gear, and 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-resistant liner, which has good wear-resistance. The machine is with stable and reliable working condition. Moreover, according to different materials and discharging methods, there are dry ball mills and wet ball mills for choosing.
The advantages of conical ball mill
( 1 ) It can be used for dry or wet milling;
( 2 ) It can be crushed in a closed machine, no dust flying;
( 3 ) It has function of reliable operation, cheap grinding and easy to replace;
( 4 ) Intermittent Operation can also be operated continuously;
Conical ball mill working principle
This small ball mill factory is a horizontal cylinder rotating device. It is equipped with drive gear which drives the cylinder for rotation in the working process outside the cylinder. There are two chambers. Materials go into the first chamber of the grinding machine spirally and evenly through the feeding hollow shaft from the feeding device, and there are ladder lining plates or ripple lining plates inside the first chamber where there are different kinds of steel balls. When the cylinder rotates, it will produce eccentric force to bring the steel balls to a certain height, the steel balls will fall down to impact and grind the materials. After being coarsely grinded in the first chamber, the materials will go into the secondary chamber where there are flat lining plates through the single-layer partition board. There are steel balls for further grinding the materials in the lining plate, and steel ball is set inside the second chamber. Materials will be grinded. Finally the powdery materials will be discharged from the discharging grating bar to complete powder grinding operation.
