An energy-saving ball press machine is a new ball press machine moderated on the ordinary one with the features of high pressure, adjustable rotate speed and the installation of the screw feeding device. The main working part of the machine is driven by the electromagnetic adjustable-speed motor; it is transmitted to the driving shaft via the belt conveyor and the cylinder gear reducer. Then the driving shaft and the driven shaft runs at the same pace through the exposed gear. The screw feeding device driven by the belt conveyor presses the materials with constraint into the main feeding mouth.The hydraumatic device can make sure that the cylinder gets axial displacement after the ball press machine sticks into the metal blocks, thus widen the distance between the two rollers. At the same time, the hard materials pass through the compression roller to avoid its damage.The static pressure ball press machine is mainly used to press or compact kinds of iron powder, ore powder, sinter and steel slag. Any kind of powder materials that need to compact can be made into ball materials by this machine. The static pressure ball press machine is mainly used to press the coal powder, coal mud, midding coal, coke powder, coking coal and metallurgy powder into cold pressing balls and refractory matters. The machine has obvious effect on the loose materials like coke powder, oxide skin, fly ash and sludge.Henan Hongxing Machinery Co., Ltd is famous for its various mining machines and other related services which include ball press machines, stone crushing machines, ore dressing machines, cement equipment and powder making machines applied in many fields around the world. The best-sellers of the company are belt conveyor, rotary kilns with different types and features.conveyor belt system: http://www.plantcrushing.com/pros/belt-conveyor.html
