Critical ball mill speed is key but hard to do

Ball mills are widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics and can be used for the dry and wet grinding for all kinds of ores and other grind-able materials.

Henan Hongxing is a professional mining machinery manufacturer which is specialized in jaw crusher, sand maker, grinding mill, ball mill, flotation machine etc. In order to give some useful suggestions on ball mill usage, here we analyze the factors affecting the production efficiency, hoping to provide some help and support for our customers.

In respect of rotating speed control, the high-efficiency production is very limited. In the meantime, only if you control the rotating speed well can you control the consumption of steel ball.

When the rotating speed of ball mill is high, the height that the ball has to be raised is high. The ball will get away from the barrel when the ball rises to certain height, and falls along the parabolic path. There is comparatively large impact force on drop point. When the ore is crushed by the impact force, the grinding effect is highest.

When the rotating speed of ball mill exceeds a certain speed (with much higher speed), the steel ball will rotate with the barrel and wont 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 dont fall.

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%~50%. When the ore-grinding concentration is larger, the grinding effect is close to the practical production.

So in the production of ball mill, to control the critical rotating speed reasonably can realize the effective control on the steel ball consumption. Meanwhile the lower on ball consumption will decrease the ore grinding production cost. Comprehensively considering, control the ball mill rotating speed perfectly will greatly improve the ball mill production efficiency and decrease the energy consumption of ball mill specific yield.

With its high quality products such as Flotation machine、Rock cone crusher、Cement mill price、Henan Hongxing mining machinery Co.Ltd has ascended in the front rank of the world in the exporting of mining equipments.
