Foundry Core Sand Mixer

Continuous Sand Mixers are a key piece of Foundry Equipment for mixing sand with binding agents. At Foundry Machinery and Spares we have developed our Sand Mixing equipment over the past 35 years and our proven design is used across our large range of continuous Sand Mixers.Foundry sand is high quality silica sand that is a by-product from the production of both ferrous and non-ferrous metal casting industries.foundry sand consists primarily of silica sand coated with a thin film of burnt carbon, residual binder (bentonite, sea coal, resins/chemicals) and dust.One of the most important analysis is impurities present in the sand such as organic matter, chloride, and sulphate. These impurities can cause corrosion and cracks on the building and lead to considerable deterioration of durability, strength and appearance.
