But the solution to the problem was fairly obvious. Wirtgen surface miners can be used to extract minerals without the use of explosives. By cutting the ground to mine the materials, they simplify the complex extraction and preparation process. Mining, crushing, and depositing the material in windrows is all carried out in a single operation.
Limestone Mining Process Summary： The output of common limestone crushing sand making production line is 100-200t/h, 200-400t/h, 200-500t/h, but with the large-scale production, 800t/h, 1000t/h or even higher capacity sand making lines will become a trend.
The most widely adopted method of limestone mining is through opencast pits with bench formation. Limestone mining causes widespread disturbance in the environment.
