Carbide Throwing Head (Rotor Tip)
Widely used in mining, sand, cement, metallurgy, hydropower engineering and other industries, for these need to withstand high-speed impact, strong wear resistance of the industry, the use of ultra-wear-resistant carbide material is the most ideal choice, the material is cemented carbide
Compared with other materials, it has the advantages of good comprehensive performance, high reliability, strong wear resistance and low price
The thrower head is the core part of the vertical impact crusher (sand making machine)
