Product introduction
The MILALION patio hob is suitable for all types of reverse and vertical drilling and can be used on a variety of cutter heads. It is mainly used in ventilation shaft excavation of mines and tunnels. Based on the rock mechanics of the formation, MILALION engineers use computational analysis to accurately calculate the cutting efficiency and direction of movement of each row of teeth to maximize the area and volume of breakage when each tooth contacts the hole wall. Alloy teeth and other raw materials are selected from domestic well-known brands, can adapt to 30MPa~200MPa of various types of rock excavation.
