When the speed of the ball mill is fixed and the filling rate is large, the steel ball will hit the material many times, the grinding area is large, the grinding effect is strong, but the power consumption is also large.
Jet mill is a kind of equipment that uses high-speed air flow energy (300~500m/s) or superheated steam (300~400℃) to make powders collide, collide, and rub against each other to make them grind.
High classifying efficiency means that those qualified grains can be discharged timely and efficiently, while low classifying efficiency means that most qualified grains are not discharged and sent to the ball mill for re-grinding, which is easy to cause over-grinding and thus affecting the separating effect.
3. If the rotation speed of the ball mill exceeds a certain limit (the rotation speed is very high), the steel ball rotates with the barrel without falling, and is in a centrifugal operation state. At this time, the steel ball has no impact effect, and the grinding effect …
It is well known that ball mill efficiency is affected by the size of the grinding media and that there is an optimum ball size that is strongly related to particle size. Bond [5] developed an empirical relationship based on maximum breakage rate in which the ideal ball size is proportional to the square root of the product size.
