Shearer pick

China's coal reserves and annual production are ranked in the forefront of the world. Since 2005, with the adjustment of coal market prices, the economic situation of coal production enterprises has improved. Major domestic coal enterprises have continuously introduced various types of integrated mining machines and semi-coal rock roadheader from Japan, Germany, the United States, the United Kingdom, Poland, Austria and Australia. The sales volume of several domestic coal mining machine manufacturers has also made breakthroughs, and the degree of mechanized coal mining in the coal industry is increasing year by year.

The cutting tooth is a tool for cutting coal, and its performance directly affects the efficiency, energy consumption, coal dust size and lump coal rate of the shearer. At present, China's annual coal production is close to 3 billion Zt, of which underground mining accounts for about 75%. With the continuous improvement of mechanized coal mining rate in large coal production enterprises, the market demand and market development potential of shearer picks should be relatively optimistic.
 
Paying attention to the development trend and sales channels of the coal roadheader pick market, collecting technical data of various shearer picks and tooth seats, exploring new production processes, and improving the quality of picks should also be one of the issues that brazing steel and drilling tools manufacturers should pay attention.
