How to Provide The Output of Dry Ball Mill for Feldspar

The dry ball mill for feldspar is the key grinding equipment of the material being broken, how to improve the output of dry ball mill for feldspar is the pursuit that manufacturers and the users have been looking for. The reasonable ball loading capacity of the dry ball mill for feldspar not only affects the grinding efficiency and the improvement of production, but also is related to the life of the dry ball mill for feldspar. Therefore, it is very important to master the reasonable balance of ball amount in the process of dry ball mill for feldspar. The following we will introduce some relevant issues on the ball of dry ball mill for feldspar.
Ball amount and the output of dry ball mill for feldspar.
The output of dry ball mill for feldspar has a direct relation with the ball amount. When dry ball mill for feldspar is working, its total efficiency depends on each steel ball work (impact frequency and impact force), therefore, it is necessary to give full play to the efficiency of each steel ball, which will make the steel ball moving along the different track (track) not collide as far as possible. If the ball is too much, the ball is easy to stack on top of each other, which makes part of the balls not fall up after be up to the required height, then they can not give full play to each ball crushing capacity, at the same time, this can increase the kinetic energy dissipation of yak. Too few, although the broken capacity of each steel ball is fully played, but the total crushing capacity is limited. Therefore, it is necessary to select the appropriate ball.
According to the actual results of the laboratory, the filling amount of steel balls is 40%, and the filling rate of steel balls in the production is about 35%, that is, to keep the ball volume is lower than the level of the center line.
How to detect wether the ball amount is suitable?
The main factor of ball amount should be considered is the size of the ball and its proportion, the number of balls installed in the production has been basically fixed down. For example, for the central discharge type dry ball mill for feldspar, the ball size should not make steel ball roll from ball mill. During the experiment, we should keep the ore particle size, fineness, classifier overflow and sand return operating conditions as much as possible, then you can check the rationality of ball filling ratio from the following two aspects.
1 If the amount of ore and the classifier overflow fineness is unchanged, and the returned sand amount is reduced, which can be proved that the ball mill grinding strengthened, then we can increase the amount of ore.
2 If mineral particles which is close to the overflow increased according to the screening results of classifier sand return, which shows the insufficient number of balls; conversely, if the coarse grain increased, it shows the big ball shortage.
Choose the suitable steel ball amount, provide your output of dry ball mill for feldspar.
