How to detect the amount of ball mill right fit? The so-called ball impact, the main ball should consider the size and proportion, as the number of ball and mill parts in production has largely been fixed, such as the central row of ore ball mill, ball its volume so as not to steel Get out of the ball from a ball mill is limited, and lattice-type ball mill volume should be about 50% by volume of the total. During the test, as far as possible to keep the mill feed size, classifier overflow fineness and return the amount of sand and other operating conditions remain unchanged, then you can check the percentage of rationality ball from the following two aspects. 1, to the amount of ore grading machine and overflow fineness unchanged, while reducing the amount of sand back, it shows the ball mill grinding action strengthened, then you can increase the volume of ore. 2, if the grading machine according to sieve analysis results back to the sand, mill works, found close to the overflow granularity of mineral particles increase, it means that an insufficient number of small ball; the other hand, if the increase in coarse, it means that an insufficient number of large balls . Factors that affect the efficiency of ball mill is the material to be broken, and then to smash the key equipment. For grinding various ores and other materials, it is widely used in mineral processing, building materials and chemical industries. In the production process, since the operating conditions can affect the efficiency of the various devices. So, Shenyang mill, ball mill efficiency factors, what does? First, the amount of milling media added. Grinding and grinding media plays a role in a ball mill strike. Add more ball mill grinding media, the more the number of times the material is milled in a unit time, high milling efficiency. But the milling media mill will occupy more space efficient, but lead to performance degradation. Second, the ball speed. Abrasive grinding mill is at the cylinder rotates, the ball and the cylinder wall and the friction with the impact of raw materials play a role and to achieve. When speed is too slow, the ball sliding down the stone rise is not another job, pulverizing effect is small. Speed ??is too fast, the grinding media can be attached to the inner wall with the rotation of the mill, the grinding material is stopped. When appropriate, the speed, the ball can take along the tube wall material rise to a certain height, when it is equal to the centrifugal force of the force of gravity, the grinding media along a parabolic trajectory falling carom in the material sphere or below, then the material by the biggest impact and abrasive, so high crushing efficiency. Third, the charge process. Mill feeding method first feeding and secondary material. First feeding is hard, add a little soft materials. Such a simple operation, but consume more power, poor grinding efficiency. Secondary material is to add a hard material, a dry ball mill, after grinding period of time, and then put into the soft ground and mixed together with raw materials. This increases the impact of the ball on the materials, the material and the stone balls have more opportunities for contact, thus increasing the grinding efficiency. Fourth, the size of the process material. Into the ball milled material more fine granularity shorter time, but too small a particle size will increase the burden of the material in pieces. So feed particle size of about 2mm more appropriate. Small ball | North Mine Zhongcheng (certified) | Shenyang Ball from Shenyang North Mine Zhongcheng machinery Limited.
