Description

TECHNICAL FIELD

[0001] The utility model relates to a self-grinding machine lining plate and belongs to the technical field of self-grinding machine equipment. BACKGROUND

[0002] The service life of the self-grinding machine lining plate is generally short, and the service life of self-grinding machine lining plates of different models varies from 6 to 10 months. The self-grinding machine lining plate is heavy, and it takes a long time to replace it once, which affects the operation rate of the self-grinding machine and has a certain impact on production organization. The lining plate consumption cost accounts for a large proportion of the ore dressing cost, and improving the service life is of great benefit to cost reduction. Research on improving the efficiency of the self-grinding machine can effectively improve the self-grinding machine's hourly output, so it is of great significance to improve the service life of the lining plate.

[0003] The lining plate is generally made of manganese steel, chromium-molybdenum steel, and composite lining plate, and the hardness is an important indicator of the wear resistance of the lining plate. The higher the hardness, the better the wear resistance. However, too high hardness can cause the lining plate to crack and break, so the service life cannot be prolonged by simply increasing the hardness. The wear resistance can be improved by adjusting the structure and reasonable arrangement. The current self-grinding machine lining plate still has the problem that deformation occurs between the two lining plates during use. The deformation can tightly squeeze the lining plate, making it impossible to disassemble. Gas welding is required to cut the lining plate, which occupies a large amount of maintenance time and reduces the maintenance efficiency. Therefore, it is necessary to improve the structure of the existing self-grinding machine lining plate. SUMMARY

[0004] The technical problem to be solved by the utility model is to provide a self-grinding machine lining plate that is wear-resistant and easy to disassemble. The self-grinding machine lining plate has good wear resistance, improves the service life of the lining plate, is easy to disassemble and maintain, greatly improves the maintenance efficiency, and improves the equipment operability.

[0005] The technical solution to solve the above technical problems is:

[0006] A self-grinding machine lining plate that is wear-resistant and easy to disassemble, comprising a cylinder lining plate, the cylinder lining plate is arranged in two rows, and the improvement is that the height of the lining plate lifting strip of the cylinder lining plate near the feed end and the discharge end of the cylinder is lower than the height of the lining plate lifting strip at the center line position of the cylinder, forming a slope shape with the two sides low and the middle high, and rubber plates are embedded on both sides of the two rows of cylinder lining plates.

[0007] The self-grinding machine lining plate that is wear-resistant and easy to disassemble also has a feed end lining plate, the middle of the feed end lining plate has a middle boss, two side bosses are added on both sides of the middle boss of the feed end lining plate, and the two side bosses are parallel to the middle boss.

[0008] The self-milling machine lining plate has a discharge end lining plate, the plane of the discharge end lining plate has ore discharging holes, the ore discharging holes are long holes, the length direction of the ore discharging holes is perpendicular to the length direction of the discharge end lining plate, and a plurality of ore discharging holes are sequentially and parallel arranged along the length direction of the discharge end lining plate.

[0009] The self-milling machine lining plate has the advantages that:

[0010] The barrel lining plate is in a slope shape with low sides and a high middle part, can balance the wear degree of the two ends and the middle part of the lining plate, improves the service life under the condition that the weight of each lining plate is unchanged, the two lining plates with embedded rubber plates can be removed first, and the efficiency of removing old lining plates is improved; the feeding end lining plate has three bosses, the steel balls and the materials first impact the boss parts, and the lining plate surface is worn only in the later period, which is equivalent to increasing the thickness of the feeding end lining plate; the discharge end lining plate is changed from a blind plate to a lining plate with ore discharging holes, so that the discharge end lining plate also plays a role in ore discharging, and the ore discharging passing area of the self-milling machine is greatly increased.

[0011] The self-milling machine lining plate has the advantages that: the structure is simple, the use is convenient, the service life of the lining plate is increased by about 20% by increasing the height of the lifting strip, the ore discharging passing area is increased, the ore grinding efficiency of the self-milling machine is improved, the ore feeding table time is increased by about 5%, and the maintenance efficiency is increased by 15%-20%.
