Notes on Adopting High Rotating Speed Ore Grinding

Ball mill is mechanically rotated on their axis, but small ones normally consist of a cylindrical capped container that sits on two drive shafts (. And belts are used to transmit rotary motion). Functions on the same principle. , but cannot be used in the preparation of some pyrotechnic mixtures such as. Because of their sensitivity to impact. High-quality ball mill is potentially expensive and can grind mixture particles to as small as 5. , enormously increasing surface is and reaction rates. The grinding works on principle of critical speed. The critical speed can be understood as that speed after which the steel balls (which is responsible for the grinding of particles) start rotating along the direction of the cylindrical device; thus causing no further grinding.

In the current ball mill products production, when the ore grinding rotating speed is less than 76% of the critical speed, it can be called the low speed ore grinding; when the rotating speed is higher than 88% of the critical speed, it can be called the high speed ore grinding; when the rotating speed is greater than 100% of the critical speed, it is supercritical rotating speed ore grinding.

It has been proved by ball mills production practice that the ball mills machine adopting the smooth lining plate is of low medium filling ratio which is between 30%-40%. Meanwhile decreasing the ore grinding thickness can raise the rotating speed of ball mill machine to 100%-104% of the critical rotating speed. By all the conditions mentioned above, the high rotating speed ore grinding can be adopted. It still can bring about bad effects to the ball mill manufacturer such as lowering the ore grinding fineness, so pursuit the high rotating speed of the ore grinding unilaterally is inadvisable.

Henan Bailing Machinery Co,.LTD is a professional ball mill manufacturer, the main ball mill products are cement ball mill, energy-saving ball mill, cone ball mill and so on. For the ball mill price, please telephone us or email us, we will tell you in detail timely.
