The overflow ball mill is a kind of selection ball mill. Its name comes from its discharge method. The overflow ball mill's discharge method is non-compulsory discharge, only when the pressure inside the barrel reaches a certain degree. When the slurry is higher than the lower edge of the hollow axis at the discharge end, it will overflow automatically. Therefore, it is more suitable for grinding mine with fine fineness.
Overflow ball mill advantage:
. Easy to start, smooth operation
The overflow ball mill is equipped with a gas clutch flexible start, easy to start; Oil mist lubrication device, ensure the size of the gear lubrication is reliable; Static pressure bearing, running smoothly and reliably; Slow transmission, easy to repair and start.
. Simple structure, convenient maintenance
The structure is simple and easy to repair. Because of the anti-screw pattern cast in the feed pipe, large ore and steel balls are not easy to discharge out of the machine. The small overflow ball grinder is equipped with an overhead device to make your maintenance and repair work more convenient.
. Lining board optional, high wear resistance
The lining of the lining can be selected according to the different types of grinding materials. The lining material includes metal lining, rubber lining, cast stone lining, etc.. The shape of the lining plate can be selected for flat lining, corrugated lining, convex edge lining, press lining, step lining, hemispherical lining, etc..
. Work in a variety of ways, granularity optional
The overflow ball grinder can work in several ways, such as dry grinder, wet grinder or mixed fine grinder; In addition, the machine also adopts advanced controllable material entry and exit technology. In combination with actual grinding materials, suitable abrasive bodies should be used, and traditional surface contact should be changed to line contact to make the feed granularity more uniform and yield higher.
Low grade magnetic iron ore can be selected with high accuracy, any grain can be selected, and coarse tailings can be discarded at any time. The equipment has low investment and quick effect.
. Tube material reliable, advanced component performance
The material of the cylinder of the overflow ball mill is made of steel plates with a thickness of 15-36mm. The flange plates made of cast steel are welded at both ends of the cylinder, and the end covers 2 and 3 are connected to the flange discs with a bolt. Together, Its precision processing and cooperation greatly improve the wear resistance of the components.
. Low labor intensity, save manpower
When the overflow type ball mill is working, its suspension time is very short, and the vibration of the machine in operation is small, which will never affect the life of the equipment. More importantly, the overflow type ball mill has low labor intensity and saves manpower for customers.
