Stone chips are one of the main construction materials along with bricks, sand, cement, and steel. Generally, you can segregate the crushed stone into various sizes like 35mm, 20mm, 12mm, etc for different uses. Crushed stone aggregates are essential for the construction of roads, bridges, housing, industrial building construction.
Additionally, it is an essential item for other cement-based products. The list includes RCC pipes, PSC poles, pre moulded slabs, frames, and beams, etc for fabrication. A stone crusher plant is a profitable venture for new entrepreneurs. The demand for quality stone chips is increasing day-by-day.
All the building constructions whether it is housing or industrial construction activities requires crushed stone. Crushed stone is also required for cement based products like RCC pipes, PSC poles, cement concrete hollow blocks, precast cement concrete slabs, well rings, window & door frames and road laying. The demand for crushed stone will continue to grow with the growth of its user industry.
One of the most particular and general but most important materials used for making concrete is stone chips. These are used as filler with binding materials in the production of concrete. Crushed stones occupy about 72-75% of the volume of concrete and they greatly influence the strength of concrete.
The good quality black stones are the most popular. However, you can set up the unit depending on the availability of raw material and major commercial center.

Stone crusher plants are available in two major types namely (a) stationary (b) portable or mobile. However, you can establish stationary crushers at quarry heads. Mainly, at the construction site, you can use the portable crushers. Here we have explained the stationary stone crusher plant details.
Stone boulders are the only raw material required for the stone crusher plant.
Stone Crusher Plant Production Process
First of all, break the big stone boulders to smaller size manually. Then it is fed to the stone crusher. The crusher can accept the stone size of 175mm. Stone crushing is the two-stage process. In the first
stage, crush the 175mm stone to about 50mm.
Thereafter, fit the crusher with a conversion kit to enable granulation of 5 to 20mm. Then screen the crushed material by the rotary screen. Unit location is a major factor for stone crusher plant business.
