Speed works on ball mill capacity

Energy saving ball mill working principle: the energy-saving ball mill is a horizontal cylinder rotating device, outer gear, warehouse two, the lattice type energy-saving ball mill. Material from the feed device feed air evenly into the mill screw shaft first warehouse, the warehouse has stepped lining board or corrugated liner, built in different specifications of steel balls, the rotation of the cylinder to generate centrifugal force will bring the steel ball to a certain height after the fall, the material produces severe impact and abrasive. Materials in the first position to coarse grinding, the board by the single compartment into the second warehouse, the warehouse lined with flat lining, steel ball inside, the material to further grinding. Powder through the discharge grate discharge, finish grinding operation.
Energy saving ball mill should be installed in a solid concrete foundation. Filter out the fine material from the overflow tube. The base of the machine adopts a channel, the machine adopts welded steel.
Rotational speed of ball mill will affect the grinding medium?
When other conditions are the same, the grinding medium in the cylinder body movement depends on the energy saving ball mill speed. The status of the medium is different, the grinding effect is also different.
Energy saving ball mill speed is too low on the production of energy-saving ball mill effects: low speed, medium to cascading movement, shock effect is smaller, the grinding action mainly for grinding, energy-saving ball mill capacity is low, suitable for fine grinding;
Energy saving ball mill speed is too high on the production capacity of impact: energy-saving ball mill at higher speed, throwing motion mode of medium proportion increases, strong impact, grinding to shock, grinding secondly, in favor of crushed coarse materials, energy-saving ball mill high production capacity. Energy saving ball mill with different filling rate, useful power reaches its maximum value when requested by the speed is not the same.
 

With its high quality products such as 、、、Henan Hongxing mining machinery Co.Ltd has ascended in the front rank of the world in the exporting of mining equipments.
