Correct application of ball mill several problems that should pay attention to



1, the ball correctly how to operate the ball mill the polisher is important problems in mineral processing. Now a hot, mining development technology is also relatively scarce, many workers without formal training and long-term work, virtually to the mining enterprise caused great economic losses. In addition, grinding operation belong to actual production experience technologies, many engineers don't quite understand, and the technology experience in all kinds of books and can't find on. Therefore, according to the author DuoNian debugging experience in production and technology on the basis of the theory of combining on grinding machine, the operation are expounded. Cone crusher

As the ball polisher operation, relatively fixed need not change often factors are: undressed ore mineral hardness, broken particle size, case screen mesh, ball mill model, steel ball quality, adding amount of steel ball, steel ball size scale, ball mill speed, the sorting machine speed, the sorting machine impeller spacing, the sorting machine main shaft hoisting height, the sorting machine blade wear, the sorting machine of the overflow weir height, the sorting machine open height, the sorting machine open size, grading the opening height, grading the opening size. This part of the factors for design and process for the early. Of course now many concentrator, equipment installation designed unreasonable or equipment quality problems. Now the first to some factors discussed in this paper.

The ball mill model selection: different ball mill type can meet different technical requirements, the factors in the design must be reasonable choice, as shown in the ball mill selection and calculation. Jaw crusher

Heart, a different size gear mesh is a deviation.

A ball reducer gear transmission parts have sand holes, equipment installation, haven't run after class, gear problems such as wear.

The key to the ball of the daily regulation polisher elaborates the important parameters, this also is the direct embodiment of the ball polisher operation level, grinding utilization efficiency of the important content. Mainly has: the ball mill water supply size, ball mill row ore in mouth flush size, gives the ore quantity size.

For ball mill bilge belly warning signs of a few respects pay attention, one is watching the ball mill to spit material, whether mine mouth is to listen to the voice, if the ball mill bulging belly, the voice smaller to become the third was stuffy, see the ball mill current control cabinet, especially to stress that, if the ball mill, the current expansion belly become smaller, and many operators and engineers think on the contrary, they think the ball mill bilge belly is because of the large amount of ore ball mill, its current value is bigger, this is the wrong point of view. Its principle is: the ball mill bulging belly, because the ball mill in the ore is more, and the amount of ore ball mill, steel ball are too, ore is along with the ball mill barrel operation, together with the ball mill row of ore mine mouth size coarsens, at this time, the ball mill, the electrical energy in smaller doing work into kinetic energy, the power and the corresponding becomes smaller, voltage, power in some smaller, cause changes is the current value decreases. jaw crusher
