The freed walls of stone are then cut into rough blocks, and diamond wire saws are used for the final trimming. Overall, the quarry produces 1,000 cubic meters of stone per month. The typical block size is 5 to 6 cubic meters, with measurements around 295 x 190 x 180 cm.

6. Waste. Quarrying can generate huge amounts of waste as unwanted materials can be dug up. For example, mining bentonite can generate around 0.83 m3 of waste per tonne, while perlite could be behind 0.39 m3 /t. Meanwhile, pozzolan one and two do not seem to generate waste as they are homogenized. Some of the waste may be recycled.

Efficiency tip. Decreasing the gap between the hammers and impact curtain increases particle retention in the chamber. This increases the size reduction ratio; however, it also reduces efficiency throughput capacity and increases fines production. Crushing efficiency begins with common crusher knowledge.

The local government may understand the value of a quarry to the local economy far more than you understand. Where I now live there are no local quarries with good rock. All the stuff for making concrete must be trucked in, after a good trip via river barge. Gravel here is ~$15 ton versus ~$3.50 in my old location.

Dimension stone is quarried by cutting, or separating by some other means, large blocks of stone from the natural rock mass. The size of individual block produced depends on a number of factors, including the homogeneity of the rock itself, the ability of the quarry operator to handle the rough stone, and the required end use for the stone …
