What is the largest model of the rock drill of Sany Heavy Industry? What can the hardness f reach? Can it reach 8 to 10?

Hello, I'm glad to answer your question. The hardness f of the largest model of rock drill of Sany Heavy Industry can reach 8~ 10. For example, Sany EBZ3 18(H) cantilever roadheader. The overall weight of the roadheader is 125t (including secondary transportation dust removal system), the undercover depth is 220mm, the cutting motor power is 3 18kW, the maximum single compressive strength of cutting rock is 130MPa, and the hardness is almost equivalent to F 13.

However, when the roadheader cuts the rock stratum, it is related to the pick. With Sany heavy roadheader, generally choose Aide hard rock pick. If the wear resistance and hardness of the pick are not good enough, even on the heavy-duty roadheader, the loss is great and the cost is high. Therefore, the roadheader should understand that the pick of the roadheader should be selected.
