Problems that should be paid attention to during the operation of Iron ore ball mill


Iron ore ball mill is the key equipment for crushing materials after crushing. This type of grinding machine is equipped with a certain number of steel balls as grinding media in its cylinder. Its cylinder body uses high wear-resistant liner, which has good wear resistance, long service life and easy maintenance. It can be divided into dry and wet grinding methods. According to different ways of discharging, it can be divided into two types: grid type and overflow type. It is widely used in cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal beneficiation, and glass ceramics and other production industries, for dry or wet grinding of various ores and other grindable materials.

How to correctly operate the Iron ore ball mill is an important issue in the beneficiation process. Nowadays, mining development is relatively hot, and skilled workers are relatively scarce. Many of them are employed without long-term formal training, which invisibly causes large economic losses to mining enterprises. In addition, the grinding operation belongs to the actual production experience technology, and many engineering and technical personnel do not understand it very well, and the technical experience in this area cannot be found in various books. For this reason, based on years of experience of Shanghai Clirik technicians, the editor has sorted out the problems that should be paid attention to when operating the ore ball mill.

First of all, operate before the operation. The factors that are relatively fixed and do not need to be adjusted frequently are: the hardness of the raw ore, the size of the crushed particle size, the grid sieve, the model of the ball mill, the quality of the steel ball, and the amount of steel ball added. Of course, many concentrators have problems with unreasonable design, equipment installation or equipment quality. Some factors will be explained first.

How to effectively improve the fineness of ore grinding is one of the important links in the entire beneficiation operation, because the cost of the grinding operation is a higher part of the beneficiation plant. How to effectively and reasonably control the fineness of the ore is to directly reduce the cost of ore dressing and increase An important factor in the economic benefits of the processing plant. Grinding fineness is one of the many factors that affect the beneficiation index. The grinding fineness directly affects the grade of the concentrate and the recovery rate of the product. Therefore, the technical operation of the ball mill is extremely important.

First of all, we must fully understand the influencing factors of grinding fineness. To sum up, the factors affecting the fineness of grinding are: the hardness of the raw ore, the size of the crushed particle size, the screen hole, the amount of the ore, the model of the ball mill, the number of steel balls, the size ratio of the steel balls, the wear of the ball mill lining, the speed of the ball mill, and the classification Machine speed, classifier main shaft lifting height, classifier blade wear, classifier overflow weir height, classifier lower opening height, classifier lower opening size, classifier opening height, classifier opening size, water flow size at the returned sand, ball mill The size of the water supply, the size of the flushing water at the discharge port of the ball mill, etc.

Knowing all these influencing factors, we need to search one by one in the production operation to find the best adjustment factor.

Different ore has different hardness. This factor is fixed relative to the same ore and cannot be adjusted. However, in production, under the premise of the technical requirements of the beneficiation process, reasonable ore blending can be carried out to make the ore size as uniform as possible, and the lump and powder ore ratio is reasonable and stable. In addition, at the ball mill belt feeding place, the belt may leak ore due to long-term wear. Most of the leakage is fine ore. This part of the leaked ore must be added to the ball mill as soon as possible. If stacked for a long time, concentrated Adding will cause uneven ball milling to ore and cause unstable production. Especially for hard-to-dress minerals, the properties of powder minerals and lump minerals are often different.

The adjustment of crushing particle size and grid sieve holes is a key issue. The ball miller must supervise the crushing system. If the particle size of the ball mill is changed during production, it must be immediately reflected in the crushing workshop. Ultimately, the finer the crushing particle size is required, the better.

In addition, different equipment and different mines have different operations on the equipment, so if you want to know more about the detailed operation of the mineral processing equipment, please contact us.
