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.
