A simple understanding of the two with the ball mill method called two with the ball method, it is to use the size of the two different specifications, and both the diameter difference between the larger ball for grading. On the theory that a large gap between the ball from small balls to fill, tailings recycling machine equipment, in order to fully enhance the bulk density of the ball. Thus, one can improve the impact strength and impact of the number of the first positions, in line with features that bin grinding media, on the other hand, higher bulk density can be able to get some material abrasive. In two match balls, big balls main function is the material for impact crusher. First, the role of small ball filling the gap between the big ball, increasing the bulk density of the grinding media, huge ring tailings recycling machines to control material flow, increase grinding capacity; the second is the role of energy transfer from the large ball impact energy transfer to the material; the third is the gap in the coarse particulate material squeezed out and placed in a large ball of the impact zone. In the multi-stage with the ball in for the ball impact, impact times, the ability to control material flow requirements are based primarily on average ball diameter, that is subject to a variety of specifications ball in. In the two-stage with the ball, the ball's impact, impact of the number determined by the large diameter of the ball, and the ability to control the flow of materials is mainly determined by the diameter, filled with a small amount of the ball, and the influence of the big ball diameter is small, and therefore easing the impact, frequency and control the impact of conflict between material flow capability. In contrast, the two-stage method is relatively simple with the ball, when determining grading parameters considered easy to do. From production changes, along with the material hardness and grain size increases, conflicts with the ball in the performance of multi-level impact and material flow control ball between the more prominent, tailings recycling machine prices, so production is more pronounced decline . In the two with the ball does not exist in this conflict, Beijing tailings recycling machines, because it can be big, small balls to satisfy the material to impact and flow control capability requirements, and therefore production did not change significantly, reflecting the two Graded ball superiority. Learn mill operation preparation, start-up and shutdown sequence using a ball mill now place a lot, but before the ball mill What precautions do you have? Here to explain: First, prepare ball before the operation: 1, check whether someone. 2, check whether the oil level is appropriate, add insufficient. 3. Check the ball filling ratio meets the requirements. 4. Check all parts are loose and reliably tighten. 5. Check the hole cover tightly secured reliably. 6, check and rectify the leak powder phenomenon. 7, the first test run or the long-term should be poured a small amount of lubricating oil after stop grinding, press the "jog" revolution, confirming that no abnormal phenomenon. 8, and related operations staff contact, allowing the signal to start after starting the mill. Second, the sequence starting mill: 1, the starting powder output device. 2, starting mill. 3, start the feeder. Third, the order of mill downtime: 1, stop feeding the machine. 2, stopped ball. Long-term stop grinding balls and materials should be emptied. 3, the material on the machine discharge after their stop. These are the preflight preparation, start-up and shutdown sequence.
