High-pressure grinding roller has significant meaning in enhancing recovery rate, lowering power and consumption as well as improving production capacity. If the high-pressure grinding roller is applied in the metallurgy mining industry (iron mine industry), it needs to increase more static pressure. This means the machine must have greater load bearing capacity and stronger wear resistance. Because of the high-pressure grinding roller is material deck crushing, the steel consumption during working process is extremely low. Pressure roller is the main bearing component and wearing part, so its improvement has great meaning for the metallurgy mining industry.
The pressure roller surface should of strong impact toughness and high wear resistance. The generally method is to weld a layer of impact resistance metal on the roller surface, and then welding another layer of wearing layer with high hardness, finally welding herringbone or "-" strip to increase the feeding materials granularity.
This kind of roller is featured of simple structure. If the wearing layer is worn, you can weld on site to meet the using requirement.
