Kandla Grey Sandstone:
Kandla Grey sandstone is also known as Bhilwara GREY sandstone, Autumn Grey Sandstone, Bundi Grey Sandstone, Kota Grey Sandstone.
It is a hard sandstone due to presence of quartz grains cemented together by secondary silica calcite. This sandstone is available in three different shades of bluish gray, dark gray, and light gray representing the quarry areas where it is produced.
The quarries are based in villages like Budhpura, Bhuti, Bhawani Nagar, Dhabi, Aaroli etc nearby the Bijolia Town based in Bhilwara District of Rajashan State.

According to study by Mr. P. Madhvan (Mine Labour Protection Campaign) & Dr. Sanjay Ray with INDIA COMMITTEE OF THE NETHERLANDS, Quarrying of sandstone, started some 50 years ago in Budhpura as a purely manual industry, is becoming increasingly mechanized. Technological upgrading is taking place in the sandstone as well as in the marble industry throughout Rajasthan.
Over the years, the quarrying area has expanded, as modern machinery can break down even the hardest of stones, exposing the soft underbelly of sandstone. The harder stones are first separated by chisels or drilling machines. Then a crowbar helps to size and split the layer along its natural cleavage to give the sandstone slab/tile a ready-to-use shape.
Quarrying equipment like gang saws, circular saws for granite, tiling plants, polishing machines, pneumatic jack hammers, diesel operated compressors, hydraulic jacks, splitting equipment, winches etc., are increasingly used in sandstone quarrying.
For loading and unloading of blocks at quarrying and processing plants – jib cranes, derricks, excavators and mobile cranes have been introduced. For removal of blocks and over-burden dumpers, trucks, tractor, trolleys etc. are used, also by quarry owners in Budhpura.
