Sand Washing Plants and Equipment, Sand Purification, Quarry Dust Washing, Sand Processing, Aggregate Washing, Sand Classification, Sand Dewatering

Industrial sand is used in GRC industries as primary component, due to Silica's High boiling point, High heat resistance, Low co-efficient of expansion, Low thermal conductivity and shrinkage. Other two properties of silica are also involved in this industry such as High porosity and High resistance to chemicals. In glass reinforcement cement fibres are used as reinforced cement and polymer resins are used as composing material. Fibres are made from silica compound by melting it up to 1710' C.
