Since its first application on a roadheader cutter boom in 1972, the conical pick equipped with tungsten-carbide tips (also called point-attack picks) has become more important and is today the most commonly used pick

what is roadheader? From Wikipedia A roadheader, also called a boom-type roadheader, road header machine, road header or just header machine, is a piece of excavating equipment consisting of a boom-mounted cutting head, a loading device usually involving a conveyor, and a crawler travelling track to move the entire machine forward into the rock face. The cutting head can be a general purpose rotating drum mounted in line or perpendicular to the boom, or can be special function heads such as jackhammer-like spikes, compression fracture micro-wheel heads like those on larger tunnel boring machines, a slicer head like a gigantic chain saw for dicing up rock, or simple jaw-like buckets of traditional excavators.

Do you know why alloy heads on bullet teeth tend to fall off? Do you know why carbide tips of bullet teeth tend to fall off early and midway through the process? What causes tungsten carbide tips to fall off easily late in the process in mining tunneling construction? The alloy head is always falling off, mainly caused by brazing process and pre-welding treatment is not in place.It is mainly divided into the case that the carbide tips falls off in the early, middle and late stages of the use process of bullet teeth.

The cutter teeth is a drilling and mining cutting tool, and the cutter teeth can be divided into five types according to the following circumstances. 1. Classification according to the type of machinery used The pick is first used as a mechanical accessory, but also a high consumable, different types of machinery use different cutter pick types. Can be according to the shearer cutter teeth, excavator cutter pick, rotary excavator cutter teeth and so on several types.

As one of the most consumed parts in mining equipment, the bullet teeth plays an important role in improving mining efficiency. 1. Bullet teeth can contribute to the development of the energy industry, thereby improving the convenience of life for ordinary consumers. 2. Bullet teeth can support the mechanical functions of shearer, boring machine, etc., and then make its work more efficient and mining more convenient. 3. Workers can also leave work early. 4. For enterprises, it can also improve earnings, the best of both worlds. Specifically, what are the uses of the bullet teeth? What are the effects on the overall extraction process?
