Shearer cutter is the preferred cutter of many mining enterprises.In fact, there are many kinds of cutting teeth of coal mining machine, such as cutter-shaped cutting teeth and pick type cutting teeth. Different cutting teeth have different working performance.In the face of a variety of mining teeth, the enterprise how to choose the teeth?
Knife-shaped teeth: the shape and structure of knife-shaped teeth are similar to the shape of a knife, so they are named knife-shaped.The biggest advantage of the cutter is that it can excavate the coal mine and cut the deep coal mine rock effectively.Why knife?This type of cutter is sharp as a knife and can be used for digging.
