Brief Introduction of cement ball mill

Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation. If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill. The point where the mill becomes a centrifuge is called the "Critical Speed", and ball mills usually operate at 65% to 75% of the critical speed.

Application of cement ball mill

Ball mill is the key equipment of beneficiation equipment for grinding after the crushing process, which is composed by feeding part, discharging part, turning part and driving part (reducer, small driving gear, electric motor and electric control) and widely used in the manufacture industries, such as cement, silicate, refractory material, new building material, fertilizer, ferrous metal, nonferrous metal and glass ceramics, moreover, according to different materials and discharging methods, there are dry ball mills and wet ball mills for choice.

Working principle of cement/clinker ball mill

This machine is a skeleton pattern ball mill with horizontal cylindrical turning gear, drive 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.

Structures of cement/clinker ball mill
Ball mill is composed of the feeding parts, discharging parts, rotary parts, transmission parts, reducer, gear, motor, electricity control, and other parts

wet ball mill in Production Line
