PRODUCTION DESCRIPTIONRubber liners of grinding machinery — Product feature

1. High abrasion resistance, long service life. For primary grinding the service life is 2-3years. For secondary grinding, the service life is 4-5 years.

2. Considering that the rubber specific weight is just 1/7 of manganese steel, the Xinhai abrasion resistant rubber liner is very light, which lowers the starting current, ensures the stable performance and reduces electricity consumption by 5-10%.

3. Reduce noise, improve working environment and noise is reduced more than 18 dB.

4. Excellent sealing, no leakage of slurry, good environment on site, high operating efficiency

5. Easy to assemble, lighten labor intensity and shorten maintenance time 3/4

6. Large effective volume and capacity

Due to the high abrasion resistance of Xinhai anti-abrasion rubber liners, it is designed thinner than manganese steel liners, the effective volume of the mill is enlarged and the capacity of the ball mill can be improved by adjusting the charge of balls properly.

Rubber liners of grinding machinery — Product application

Xinhai super anti-abrasion rubber liners adopt high-low combination structure, that is, the lifting bars are combined with the liners. According to the specification and revolution of the mill, feed hardness, particle size, medium kinds, granularity and quality of the product required, and the working state of the mill dynamically simulated by the computer, we can confirm the height, width and the shape of lifting bar and liners made of super anti-abrasion rubber. Meanwhile due to the different grinding technology and abrasion mechanism of mill liners, various rubbers can be chosen to achieve the best grinding effect and longest service life. At present, Xinhai has already developed more than 30kinds of super anti-abrasion rubber liners.

Rubber liners of grinding machinery — Product principle

Grinding material is achieved by lifting steel balls moved with the lifting bar while working.
