1. Grinding cost is a high part of concentrator. How to effectively and reasonably control grinding fineness is an important factor to directly rece the cost of beneficiation and improve the economic benefit of concentrator. Because the grinding fineness is one of the many factors that affect the mineral processing index, the size of grinding fineness directly affects the concentrate grade and proct recovery. Therefore, the technical operation of ball grinder is very important
first of all, it is necessary to fully understand the influencing factors of grinding fineness. To sum up, the factors affecting the grinding fineness are: raw ore hardness, crushing particle size, mesh size, feeding capacity, ball mill model, number of steel balls, size ratio of steel balls, wear of lining plate of ball mill, speed of ball mill, speed of classifier, lifting height of main shaft of classifier, wear of classifier blade, overflow weir of classifier, lower opening of classifier The size of the lower opening of the classifier, the height of the upper opening of the classifier, the size of the upper opening of the classifier, the size of the water flow at the sand return, the size of the water supply to the ball mill, and the size of the flushing water at the discharge port of the ball mill, etc
after understanding all these influencing factors, we need to find out the best adjusting factors one by one in the proction operation
hardness of raw ore: different ores have different hardness, which is fixed relative to the same ore and cannot be adjusted. But in proction, under the premise of the technical requirements of mineral processing technology, reasonable ore blending can be carried out to make the ore size as uniform as possible, and the proportion of massive and powdery ore is reasonable and stable. In addition, in the ball mill belt feeding place, the belt may leak ore e to long-term wear, and most of the leakage is fine ore. this part of the leakage ore must be added to the ball mill as soon as possible. If it is piled up for a long time and added intensively, it will cause uneven ball mill feeding and unstable proction. In particular, it is difficult to beneficiate, and the properties of fine minerals and lump minerals are often different
the lifting height of the classifier spindle is also an important factor affecting the amount of return sand and grinding fineness. Generally, the main shaft of the classifier should be put in place in normal proction. After the equipment maintenance, the ball grinder in some concentrators failed to clean up the ore in the classifier, and the ore slime settled more solid after a long time of settling. When lowering the main shaft of the classifier, e to carelessness, the main shaft was not completely lowered, resulting in less sand return than normal. In addition, if the spindle is not put down, it may be that the spindle has not been cleaned and oiled for a long time, so attention should be paid ring operation
the adjustment of crushing particle size and sieve hole is the key. The ball mill worker must supervise the crushing system. If the particle size of the ball mill changes in proction, it must be reflected to the crushing workshop immediately. Finally, the finer the crushing particle size, the better. Classifier blade wear: after the blade wear, relative to the amount of return sand is reced, resulting in the coarsening of grinding fineness. In addition, if the blade wear is severe, it will affect the classifier life, so check the blade wear in time and replace the worn blade in time. Ball mill speed, classifier speed, classifier impeller spacing: it has been set at the time of purchase of ball mill. Pay attention to check and consult at the time of purchase. The height of overflow weir of classifier affects the size of sedimentation area of ore. in proction, we can adjust the height of overflow weir of classifier appropriately according to the requirements of grinding fineness. If grinding fineness is required to be reced, the overflow weir of classifier can be adjusted, Angle iron with a certain height can be welded on both sides of the classifier, and the height of overflow weir of the classifier can be adjusted by inserting a wooden wrench. Sometimes, the height of overflow weir can be naturally increased by long-term accumulation of slime
the size of the lower opening of the classifier, the size of the lower opening of the classifier, the size of the upper opening of the classifier and the size of the upper opening of the classifier are made on site ring the installation of the equipment. In many concentrators, the size of the opening of the classifier is not adjusted properly ring the installation of the equipment, and the workers do not pay much attention to it ring the operation, which virtually affects the grinding operation. The lower opening of the classifier is low, and the ore sedimentation area is relatively large, so the amount of return sand will be large, and the grinding fineness will be relatively fine. The lower opening of the classifier is large, and the ore sedimentation area is relatively large, and the water flow is relatively gentle, so the amount of return sand will be large, the grinding fineness will be relatively small, and the upper opening of the classifier will be large, The relative return sand amount is relatively large and the grinding fineness is relatively fine. Otherwise, the opposite is true
first of all, we should assume that all other factors are normal, and the principle is: when the grinding fineness is fixed, we should maximize the processing capacity, which can effectively improve the proction efficiency Relatively speaking, the finer the grinding fineness is, the more sufficient the dissociation between useful minerals and gangue minerals is, which is beneficial to improve the metal recovery. Therefore, under the condition of a certain amount of ore, the grinding fineness should be improved as much as possible. In addition, grinding is the first link of mineral processing technology, in order to ensure the stability of proction, grinding should be as stable as possible
under the condition of a certain amount of ore feeding, the size of flushing water and ore feeding directly affect the fineness of grinding. In many domestic mines, grinding automation is not realized, and the size of water is directly adjusted by ball grinder manually, because the water flow in these two places is large, it is difficult to see the increase and decrease, Therefore, careful observation and fine adjustment are required. First of all, we understand that as the feed water of the ball mill increases, the grinding concentration becomes thinner and the grinding fineness becomes coarser. On the contrary, as the feed water of the ball mill decreases, the grinding concentration becomes larger and the grinding fineness becomes finer. The flushing water at the discharge port of ball mill becomes larger, the overflow flow becomes thinner, and the overflow fineness becomes smaller. On the contrary, the flushing water at the outlet of the ball mill becomes smaller, the overflow becomes thicker, and the overflow fineness becomes thicker. Therefore, in other conditions, including the same amount of ore, to improve the grinding fineness, the feed water of the ball mill can be reced, and the flushing water at the discharge port of the ball mill can be increased. It is better to adjust these two conditions at the same time, so as to rece the fluctuation of flotation caused by the change of the pulp amount caused by the adjustment of grinding fineness. In many concentrators, e to the operation of ball grinder, the amount of ore paddle changes greatly, resulting in the instability of flotation liquid level. If the flotation worker does not deal with it in time, it will cause the change of metal recovery and grade. If the grinding fineness is coarsened, it will be the opposite
on the premise of ensuring the grinding fineness, the feeding capacity of the ball mill can be increased. The size of ore feeding is to meet the requirements of grinding fineness while the ball mill does not expand. The whole process must be carried out in all aspects of the subtle operation
the above is the way that Shanghai Tongli provides for you to improve the grinding fineness of ball mill. The situation of each ball mill is different. We suggest that you'd better ask Shanghai Tongli () to make better arrangement!

Artificial intelligence instry chain is divided into basic layer, technology layer and application layer. The foundation layer is the basis of the AI instry chain, which provides computing power support and data input for AI. China has a short development time in this field, and the development of the foundation layer is relatively weak. At present, China's AI enterprises are mainly concentrated in Beijing, Guangdong, Shanghai and Zhejiang, and Beijing's AI development has entered the fast lane

overview of the AI instry chain: the development of the basic layer is weak

the basic layer mainly provides computing power and data support, mainly involving the source and collection of data, including AI chips, sensors, big data, cloud computing, open source framework and data processing services. The data mining, learning and intelligent processing of the technology layer are the bridge between the basic layer and the specific application layer, mainly including machine learning, deep learning, computer vision, natural language processing, speech recognition and so on. According to different scenarios, the application layer applies artificial intelligence technology for commercial landing. The main application fields are driving, security, medical, finance, ecation, etc
