Fast Speed abrasive rock Odex overburden drilling systems
Description:
Applications:
Blast hole:When hard rock is mined, the method of blasting is required. It is used to punch holes in the rock and then fill them with explosives. Blasting.
Mining:Mining is divided into open mining and underground mining. They need to be drilled.
1, The hard alloy tooth material adopts high wear-resisting formula, and the breaking rate is less than 2%.
2, the pants body is made of high-strength high-quality alloy steel. After advanced heat treatment process, the rate of broken pants is less than 1%.
3, using advanced CNC CNC machining and advanced alloy tooth assembly process, the tooth loss rate is less than 2%.
