Mining Machine Spare Parts Spherical Round Ceramic Foundry Sand For
Moulding Casting
1. Spherical ceramic sand for foundry
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.ceramic sand
2. CERAMIC SAND Characteristic
Anti Burn-on
High Reclamation Yield
Thermal Expansion Control
Wide Choice of Particle Size
Reduced Waste and Health Hazard
Good Flowability and Heat Conductivity
Low Resin Consumption and Gas Defects
