Ball mill speed effects product and efficiency

Ball mill speed effects product and efficiency

In fact, whether the , energy-saving ball mill, large-scale ball mill, or the planet ball mill used in college laboratory,cement ball mill in cement industry, their working principle is similar basically. Therefore, the factors affecting their speed have something in common. The working principle of ball mill is driven by revolution and auto-rotating, crushing the samples by the friction force and percussive force in the grinding warehouse. The higher speed, the heavier friction and percussive. Generally, discharging grain is in direct proportion to the ball mill speed.
 
In different mineral industry, the effects of ball mill speed are different. For example, in coal mine industry, the speed of theball mill is directly influencing the movement condition of the ball and coal sheet. It also influences coal grinding process. If the rotary speed is very low, steel ball and coal sheet cannot be taken up, only the lower mill is rolling, the coal output is small. Instead, if the speed reach high, the centrifugal of the ball and coal is greater than the gravity. The ball and coal sheet will rotate together with the drum, losing the role of grinding coal sheet. Rotary ball mill’ speed can make the ball in the rotary drum achieve maximum hoisting height, and then the ball reach the biggest impact, grinding effect is perfect. However, in ball mill practical work, its speed is limited by transmission device speed and external other conditions. The ball mill is impossible to achieve optimal height, it is generally close to each other.
 
From the above, we know the importance of the ball mill speed in its daily work. Consequently, the speed of ball mill should be set up to maximum to improve the grinding efficiency.

.Energy-saving Ball Mill:
The series of ball mill has made a great improvement in the structure compared to the traditional ones. Its cylinder and supporting fame compose an integral system, thus, when it is being fixed, it will be hung on the foundation once. Equipped with double-tiered centripetal roller bearing, its power consumption will be reduced by 30%. The intrinsic grill pattern forcing discharge is replaced by overall pattern controlling discharge, which enhances the fineness of final product, and meanwhile increase the capacity by 15-20%.
Cone ball mill:
This series of ball mill is widely used in grinding clinker, carbonate, fireproof stuff , and chemical materials , also can be used in beneficiation industry to grind the ores before selection.
