Casting used Ceramsite Spherical Ceramic Of Mining Machine Spare Parts
1. Spherical ceramic sand for foundry Of Mining Machine Spare Parts
In order to reduce waste emissions and health hazards to people in classic foundry process, as well as to improve foundry efficiency, Luoyang Kailn Foundry Material Company has developed a new special foundry sand, ceramic sand.
Due to ceramic sand outstanding properties, ceramic sand has been widely used in most types of foundry process as an upgrade substitution of silica sand and special foundry sands.
