Ball mill liners are often the cause of damaged equipment is often in front of the PEX series jaw crusher, ball mill and the corresponding classifier connected to do for the next process mill, through the crusher to a few seconds meters below the rock by a conveyor into a ball mill grinding a long time to process, but the liner in the process played a role in the protection of the cylinder, the ball is grinding to reports, nothing other details, see the following: First, the grinding effect of grinding media ball mill grinding of raw materials often include: various types of mines, Liaoning centrifugal filter materials, various types of non-metallic mineral Liaoning centrifugal filter, and coal used in the power industry. Hardness index medium is an important reason decided liner wear failure, the shorter the higher the hardness of the ore, lining life, and vice versa, using the period will grow. Second, the impact of a job runs to avoid the defect is not repaired in time, for example, loose bolts fall, individual liner off, if not timely replacement of the case, the defect will gradually spread, causing other liners and cylinder a lot of damage. 2, feed unevenly, improperly adjusted, short positions appear to run state, resulting in direct friction ball and hit the cylinder and liner, the formation of two-body wear, this fragmentation of the liner and ball, wear substantial opportunity Liaoning centrifugal filter increases, causing great damage to the liner, is a very bad mode of operation. Third, the impact ball mill liner material according to the physical properties of the liner material, the main parameters affecting the wear effect of hardness and toughness of two indicators match the problem, the higher the hardness of the material, then wear the better, may to achieve a proportional relationship, so that the ball mill during operation, the ball falling like a waterfall, to produce a shock lining materials and power, size depends on the size of the impact energy, the size of the ball diameter and the diameter of the mill shell . Fourth, the mill design and manufacture and installation of technology impact liner has two roles, one in Liaoning centrifugal filter to protect the cylinder, and the other is the specific speed of the ball raised to the required height, the ball was falling waterfall , milled to achieve the desired effect. 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.
