Product Description
Dry 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.
Structures of high-efficient and energy-saving dry ball mills :
The machine is composed by feeding part,discharging part,rotation part and driving part(reducer,small driving gear,electric motor and electric control).
Features of high-efficient and energy-saving dry ball mills :
1. Large application range, simple structure and convenient maintenance;
2. Large capacity and continuous work are obvious advantages;
3. Various barrel lining and grinding media, excellent corrosion resistance;
4. Installation and adjustment are very convenient and easy to operate.
5.Cylinder is rolled and welded with Q235B steel plate. (the steel thickness is generally 1/100 of the cylinder diameter, for example ball mill of Φ1500, the steel plate thickness is 16 mm), the material of inlet and outlet hollow shaft is ZG35.
6.The hollow axis adopts the cast steel and the lining can replace, the rotating big gear processes in the way of casting rolling gear. The barrel body is wearable well and bears wearable scaleboard. This machine run steadily and works reliably.
