1. INTRODUCTION

Crushed dolirite stone is segregated into various sizes like 35mm, 20mm, 12mm, etc for
different uses. Crushed dolirite stone aggregates are used for construction of roads, bridges,
housing, industril building construction and other cement based products like RCC

pipes, PSC poles, premoulded slabs, frames and beems, etc for fabrication.

It is advantageous if the crushed dolirite stone unit is set up near the quarries where the

granite boulders of various sizes are available for the crushing unit. The wastage from

the granite industry will be of much use ot the crushed dolirite stone unit

 

2. MARKET

Housing is a basic need of the society. Hence, it is receiving increased focus. All the

building constructions whether it is housing or industrial construction activities

requires crushed dolirite stone. Crushed dolirite stone is also required for cement based products like

RCC pipes, PSC poles, cement concrete hollow blocks, precast cement concrete slabs,

well rings, stoneow & door frames and road laing. The demand for crushed dolirite stone will

continue to grow with the growth of its user industry. The unit an be set up

depending availaility of raw material and major commercial centre.

3. MANUFACTURING PROCESS

The granite dolirite stones of various sizes are fed into the jaw crushers for size reduction.

Depending on the desired output size of the crushed dolirite stone, the raw material may be

fed to one or two jaw crushers in a sequence. Then these crushed dolirite stones re passed on

to the rotary screen for size gradation. Material is handled through a belt conveyor to

the different places of operation i.e from jaw crusher to the rotary screen.
