product structure and characteristics
The product mainly includes simplified lifting bar. Simplified village board, end lifting bar, etc. It is made of high wear-resistant rubber and super hard wear-resistant alloy, compounded by high temperature and high pressure. It has the characteristics of super impact resistance, high wear resistance, long service life, convenient installation and replacement, saving power consumption, reducing noise, etc. This product is specially used in a section of overflow ball mill. Grid-type ball mill, multi-bin. Autogenous mill, rod mill. It can effectively solve the problems of short service life of lining plate, large ball consumption and power consumption, and fast wear of transmission parts of the machine caused by the working conditions of large diameter and coarse feeding of rough grinding steel balls in the first section of the park. The diameter of the machine is Φ 1200-Φ 7300 (length is not limited), and the maximum specification of the self-grinding machine can reach Φ 10500.
Table box-rubber lining plate
Since our company spontaneously developed alloy liner in 2008, combined with international advanced technology, in accordance with the domestic market conditions and the needs of the grinding principle, after market test and application in recent years, it has been affirmed by the metallurgical, mining, chemical industry and non-ferrous metal industry, and the product quality has reached the international leading level in the same industry. The product is used in the 1.2 section of the mineral processing mill, and the service life of the traditional manganese steel product is greatly improved without affecting the working conditions and the grinding principle. Under the same working conditions and grinding principle, the service life can be extended by more than 4 months on the 1-stage mill, and the service life can be extended by more than 8 months on the 2-stage mill.
At present, the composite liner developed by the company has been rated as "Hubei Province High-tech Product" in 2014. It can be seen that the composite liner used in the-section mill has considerable economic benefits compared with the manganese steel liner. The service life and comprehensive economic benefits on the 2-section mill are much higher than those of the manganese steel liner: compared with the magnetic liner, it can correspondingly save about 15% of the steel ball loss, the hourly throughput is about 10% higher than that of the magnetic liner. Because the composite lining board can comprehensively play and overcome the advantages and disadvantages of manganese steel lining board and rubber lining board, it has better comprehensive economic benefits. Therefore, the composite lining board is the development trend of mill application in the future. The following is a brief description of the comparison with the manganese steel liner:
1. Weight ratio: The total weight of a set of composite liners of the same type of mill is only 1/3 of that of manganese steel liners. The weight reduction reduces the load on the mill bearings and driving devices, and at the same time reduces power consumption, thus truly saving energy and reducing consumption.
2. Easy to install: 3-5 people can operate the installation. The operation of the mill can reduce the noise at the same time. Compared with the traditional manganese steel liner, it can reduce the noise by 10 decibels, so it not only improves the working environment, but also enhances the safety of the installation and operation of the workers.
3. Reduce the maintenance time: in the process of using the composite liner, because the fastener of the composite liner is at the bottom of the product, there will be no impact with the simplified steel ball and the material in the working process, so there will be no slurry leakage or liner falling off. However, the traditional manganese steel lining plate fastener is on the surface of the lining plate. After friction and impact with the steel ball material during the working process of the mill, it is easy to produce bolts and loose, resulting in slurry leakage or manganese steel lining plate being smashed and falling off.
4. Cost performance: the price of a single set of composite lining plate and a single set of manganese steel lining plate price ratio is basically the same, and according to the actual service life to calculate, composite village plate can extend the life and save energy consumption, relative than manganese steel lining plate to save 30%-50% of the material cost, the overall benefit is considerable.
