Housing is a basic need of the society. Hence it is receiving increased focus and support from the Government whether it is housing or industrial construction activities, all building constructions requires crushed stone. Crushed stone is also required for cement based products like RCC pipes, PSC poles, cement concrete slabs, well rings, window and door frames and road laying. Demand for crushed stone will continue to grow with the growth of its user industry.
Crushed stone is also known as metal jelly. Crushed stone is segregated into various sizes viz. 35mm, 20mm, 12mm etc. for different uses. Crushed stone aggregates are used for construction of roads, bridges, housing, industrial building construction and other cement based products like RCC pipes, PSC poles, pre-moulded slabs, frames and beams etc. for fabrication.
Manufacturing Process : It is advantageous if the crushed stone unit is set up near the queries where the granite boulders of various sizes are available for the crushing unit. The wastage from the granite industry will be of much use to the crushed stone unit. The granite stones of various sizes are fed into the jaw crushers for size reduction. Depending on the desired output size of the crushed stone, the raw materials may be fed to one or two jaw crushers in a sequence. Then these crushed stones are passed on to the rotary screen for size gradation. Material is handled through a belt conveyor to the different places of operation.
