Type: coal cutter
Applicable rock stratum: it is suitable for mining coal, gangue and soft hard rock strata.
Specification parameters: j72 / 59 / 94 / 35 - 30 (u95) Note: the corresponding alloy pick type is in brackets, which can be customized according to customer requirements.
Product details: diamond polycrystalline cemented carbide composite bit is used for diamond pick, which is composed of diamond powder and cemented carbide matrix The superhard material synthesized at one time under the conditions of 100 000 atmospheres and 1500 ℃ high temperature has both the wear resistance of diamond and the impact toughness of cemented carbide. When it is used as the pick head to excavate hard rock, the service life is 5-20 times of that of the alloy pick, and the efficiency is increased by 10-30%. At the same time, the shutdown rate and labor intensity of workers are reduced by 90%
