(1) Crushing particle size
crushing particle size, according to the requirements of grinding fineness in proction, the feeding particle size of ball mill should be observed at any time. If the size of feed particle changes ring the proction of ball mill, the height of overflow weir of classifier will affect the size of sedimentation area of ore, so the height of overflow weir of classifier can be adjusted by inserting wood wrench. Sometimes, after long-term accumulation of slime, the final crushing size of ore is required to be - 12mm. It is necessary to supervise the crushing system. Angle iron with a certain height should be welded on both sides of the classifier. The adjustment of the mesh of the grid screen is crucial, which can naturally increase the height of the overflow weir. It must be reflected to the crushing section immediately, and the height of overflow weir of some classifiers should be adjusted appropriately
(2) classifier blade wear
strictly implement the equipment inspection system, if the blade wear is serious, and the operator does not pay much attention in the operation process, the relative amount of sand return is relatively large, the water flow is relatively gentle, and the ore deposit area is relatively large, replace the worn blade in time. The lower opening on the classifier will lead to coarsening of grinding fineness. Therefore, the relatively large amount of return sand will also affect the service life of the classifier. The larger the sedimentation area of ore will also affect the grinding operation. The grinding fineness will become smaller, which means that the amount of return sand will decrease. The opening on the classifier will be larger, and the amount of return sand will increase. In addition, the grinding fineness is relatively fine. After the classifier blade is worn, the grinding fineness becomes relatively fine. If the lower opening of the classifier is large and the lower opening of the classifier is low, the amount of return sand will be large and the grinding fineness will be relatively fine. During the equipment installation, it was confirmed on site that the blade wear should be checked regularly ring the operation, and the size of classifier opening was not adjusted properly ring the equipment installation. For example, for the blade wear phenomenon, Yantai Xinhai mining machine uses a unique material groove type annular lining plate, which increases the contact surface of spherical ore, strengthens the grinding effect, improves the ore lifting ability, reces the energy consumption, and greatly improves the grinding effect
(3) when the spindle is lifted
the height of the classifier spindle will lead to less sand return than normal. If the spindle is not cleaned and refueled for a long time, because the ore in the classifier is not cleaned up, it is also an important factor affecting the amount of return sand and grinding fineness. Sometimes, after the equipment is overhauled, it will deposit for a long time. When lowering the main shaft of the classifier, the main shaft of the classifier is generally required to be put in place in normal proction. The slime deposit is relatively solid, and the spindle is not put down completely, so more attention should be paid in the operation process. In addition, if you are not careful, the spindle will not be fully lowered
(4) water supply
in the case of a certain amount of ore feeding, the size of flushing water at the discharge port and the size of ore feeding directly affect the grinding fineness. In the case of no grinding automation, the size of water supply is directly adjusted by the ball mill operator manually. Because the water flow in these two places is large, it is difficult to see the increase and decrease, so careful observation and fine adjustment must be carried out. When the feed water of ball mill increases, the grinding concentration becomes thinner and the grinding fineness becomes coarser; On the contrary, when the feed water of ball mill decreases, the grinding concentration increases and the grinding fineness decreases. 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
(5) ore hardness
for different ores, the belt may leak ore e to long-term wear, and the hardness is not the same. Most of the leaking ore is fine ore, especially the ore from Jinding mine. The hardness is relatively high, so it is necessary to add it intensively. This factor is fixed relative to the same ore, which will cause uneven feeding of ball mill, and can not be adjusted. In addition, on the premise of meeting the technical requirements of beneficiation process, this part of the leakage ore must be added to the ball mill as soon as possible at the belt feeding place of the ball mill, so that the reasonable ore blending can be carried out. If the ore is piled up for a long time, the size of the ore should be uniform as far as possible, causing unstable proction. But in the proction, the proportion of powder ore and block ore is reasonable and stable. 1 bearing shaft overheated
ring the operation of the abrasive, the spherical bearing has the function of automatically adjusting the coaxiality of the hollow shaft and bearing bush, the temperature of the abrasive graally reces from top to bottom, resulting in the axial thermal deformation of the cylinder, causing thermal expansion, forming arc-shaped oil guide groove and graally narrowing wedge gap, and causing cold shrinkage after shutdown, so as to polish and smooth the burr that has been pulled up. Then, scraping and repairing both sides of the Bush mouth of the Bush may make the Bush heat e to the axial force. The journal shall be polished with fine oilstone to prevent the bearing surface from being damaged. Only the back of abrasive cloth shall be polished several times
2 the big gear ring is turned over to use
the original big gear is disassembled on the cylinder, the original non meshing tooth surface is polished, and the screw hole diameter and the upper and lower surfaces are not scarred as far as possible ring the disassembly. Open the split gear, grind off the burr and scratch, release the stress, assemble the two halves of the gear, re grind the corresponding surfaces on both sides, and smooth the defects such as rust spots, pin holes and screw holes, edge deformation, etc. Turn the big gear over 180 degrees ° When hoisting to the cylinder, tighten 2 bolts on each side first, and the matching joint surface shall be closely connected. Check the pitch of the two half gears to rece the radial error of the big gear
3 the cylinder cracks
the weld does not meet the welding standard, and the most stressed part is located at both ends of the cylinder, which may also proce cracks. According to the analysis of bending stress and shear stress of cylinder, in addition to the use of transition steel plate, the welding of end plate and cylinder is very important. Using the self weight of the ball mill, the anti deformation plate is welded on the top of the cylinder and covered on the crack. The root of the weld should be cleaned in the mill. The crack of the weld makes the cylinder expand outside. The original weld bead should be removed after the original position is restored. After welding outside the mill, if welding directly, it will cause fracture again in the later proction. And welding to eliminate the internal stress

Suspension device
suspension device is the connecting mechanism between cage and wire rope, which is a safety device. At present, most of the domestic mines adopt hydraulic screw, hydraulic cushion block type suspension device and multi rope lifting wire rope tension automatic balance suspension device
the multi rope lifting wire rope tension automatic balance suspension device is aimed at the problem that the hydraulic screw type and hydraulic cushion block type rope adjusters commonly used at home and abroad can not automatically adjust the wire rope tension. The device adopts an automatic balance system with closed connection and pull-out clasp structure, which is safe, reliable, compact and beautiful, and can realize the wire rope tension in motion with high precision Automatic balance under static state improves the operation, safety, reliability and operation efficiency of the hoist, reces the uneven wear of the liner and the times of turning the rope groove, prolongs the service life of the liner and wire rope, and greatly reces the maintenance workload
guide device
the roller can ear is a guide device which is installed on the cage and runs up and down along the rigid combined tank channel. It can not only be used as a guide wheel for cage to run along the channel, but also connect the cage with the channel, and transfer the force between the cage and the channel. It is not only an important device for safe and stable operation of cage, but also a key part affecting the working stability of shaft equipment. Roller cage ear is the medium of interaction between cage and shaft equipment, and its working performance plays a very important role in the working quality of shaft rigid equipment. The cage must be equipped with roller ears which are suitable for the cage and the conditions of the well channel
at present, there are many kinds of roller materials, such as wear-resistant rubber, ordinary rubber, polymer materials and so on. Buffer device is more, such as ordinary spring buffer device, hydraulic buffer device, torsion rubber spring buffer device, disc spring and so on. The buffer spring is a composite structure, which is equipped with spring, spring preload and roller position adjustment device. The spring is disc spring with sealing device. A spring preload adjusting device and a spring suspension length adjusting device are simultaneously arranged on the sealing shell, and the spring suspension length adjusting device is used to adjust the position of the roller. The utility model has the advantages that the position adjustment of the worn roller is simple and convenient. The spring pre tightening force is easy to adjust, the spring is sealed in the shell, the work is reliable, and the service life is long
body
body is composed of upper, middle and lower plates, car stopper and column. The suspension device is directly connected with the main body, that is, the main and auxiliary suspenders and the four corner plates are canceled, and the suspension device is directly connected with the main beam, which not only reces the height of the cage and the height of the well tower, but also greatly reces the weight of the main body, with simple structure and convenient installation
the hanging plate is the main force bearing part of the cage, which bears all the load of the cage, the dead weight of the equipment, the weight of the tail rope and the friction resistance between the roller and the channel ring operation. Therefore, the material selection and process requirements are very strict. The main girder is the main stressed part of the cage, so great attention should be paid to the calculation, material selection and manufacturing. During manufacturing, it must be noted that the rolling direction of the steel plate should be consistent with the stress direction, the machining allowance of 10 ~ 20 mm should be reserved around, and the flaw detection should be carried out in strict accordance with the relevant standards, and the steel plate can be assembled and formed only after it is qualified
the car stopper adopts rail surface bump and sliding car stopper, which is used together with pin gear operation equipment
to sum up, the design and manufacturing process of large cage has been graally improved, and it is widely used at home and abroad, so it is the preferred equipment for large mines. For example, the cage of Yantai Xinhai mine adopts multi rope friction hoist, steel rope tension automatic balance suspension device and liquid immersion disc spring roller cage ear, plus the use of advanced anti-corrosion measures, integrating various advantages, the equipment will play a maximum efficiency in the process of transportation and lifting
