The Mining Machinery Liners Wear Ability: Wear Rubber VS Polyurethane

The choice of mining machinery, equipment wear resistance is a problem that must be taken into account. The wear resistance is a direct impact on the service life of machinery and equipment for many mining equipment. while the length of the life of the equipment means that the level of cost. In the field of mining machinery, polyurethane is a wear-resistant material for a wide range of applications. Polyurethane is a polymer synthetic material with rubber similar performance: wear-resistant, good elasticity, high strength. Using areas is almost coinciding with rubber applications. 

It has some advantages compared with rubber, good plasticity, can produce a variety of objects. its higher hardness for example, the mining machinery ball mill grinding equipment, in the ball mill cylinder lined with high hardness polyurethane, either crushing the ore, can also protect the cylinder. While because of the rubber soft texture, you can not meet this requirement of the ball mill. For polyurethane, more attractive is low cost, cheap, widely used in the market, many mining machine manufacturers use polyurethane as a wear-resistant material.

But actually, from wear resistance to make comparison, a conventional rubber product is stronger than polyurethane about 2 times. 

Presently Domestic market, a rubber specifically for equipment design and manufacture for mining machinery, its wear resistance is 2-3 times higher than ordinary rubber 4-5 times higher than the polyurethane, and corrosion-resistant, anti-aging. The most important thing is the rubber for ball mill or rubber products the price is very low, no one can be the enemy of its price in the domestic.

In contrast, although the polyurethane low price, but the overall letter bid is very low, the latter part of the maintenance and replacement of equipment will produce the higher cost, therefore, in the choice of mining equipment, ball mill lined with rubber products is better.
