Phoenix wear-resisting specializing in the production of grinding head plate, ball mill grinding head plate, special double metal composite process, ensure that the abrasion resistance and toughness of lining board of the grinding head, grinding head lining board is also available to customize and improve the service.

The reasonable design of lining board of the grinding head geometry Grinding head plate is installed in the grinding head end cover or simplified end cover (for flat plate welding on simplified) on the inner wall of liner.Its main function is to protect the inner wall of the end cover is worn by the grinding medium and material.If the design is reasonable will also be reasonable gradation.

The geometric shape of lining board of the grinding head is different, its service life and scrap rate is different.For the service life of the grinding head plate and steel scrap rate factors affecting the first on the one hand, phoenix shape wear according to the actual circumstance of mill design reasonable grinding head plate geometry, improve life of the mill grinding head lining board and reduce the scrap rate, so as to improve the operation rate of mill, to reduce the metal consumption and production cost.
