When the rotating speed of ball mill exceeds a certain speed (with much higher speed), the steel ball will rotate with the barrel and won't fall down, in a condition of centrifugal movement. There is no impact force, so the grinding function is much less, and the ball mill stop grinding. The ball mill rotating speed is called critical speed when the outmost layer balls just rotate with the barrel and don't fall.
In recent years to make the country prosperous the ball mill experts continuous technological innovation, the successive introduction of new projects, new products, constantly refreshed product record and the continuous growth in enterprise sales income to energy-saving ball mill equipment unique charm effects and mysterious. Ming letter today about the structural description of the expected out of the Ministry of the ball mill.
Feeding part of the ball mill equipment: slip-tube or spoon style, lined with 10mm thick at the bottom of manganese steel liner.
The cover of the ball mill equipment and hollow shaft: material for cast steel or alloy steel parts, the mainframe end cap and hollow shaft separate manufacturing, the minicomputer cover and in the control shaft cast together.
The feed section of the ball mill equipment: feed the mouth of the inner wall of the star spiral, force feeding function and occasional steel ball into the spiral tube can return. The feed cap journalled width greater than the width of the bearing bush 20 mm, to accommodate the deformation of the rotary portion Rezhanglengsu caused. To a service-oriented brand integrity, as the professional manufacturer of complete sets of mining machinery, like rock crushing plant, Henan Hongxing is always doing the best in products and service.rock pulverizer: http://www.crusher-machine.com/n217.html
Discharging part of the ball mill equipment: discharge outlet the journal end face positioned according to the width of the bearing bush, to this end for the fixed end of ball mill equipment body. The cylindrical sieve material is 1Cr18Ni9 Ti, internal addition of helical structure, larger particles through the coil to return to the cylinder body to continue grinding, cylindrical screen also has a washing water means and the air vent.
The critical speed of various ball mills is in direct proportion with its diameter, the absolute figure of critical speed is hard to calculated, and now only the calculation formula on critical speed in theory is widely used. When the non-smooth lining plate is used, the filing ratio of ball load is among 40 percent~50 percent. When the ore-grinding concentration is larger, the grinding effect is close to the practical production. As the professional manufacturer of complete sets of mining machinery, such as m
