Feature
1.Barrel adopts spiral wear resistant strips ,anti-attrition,prolong service life.
2.Heightening design,high construction efficiency ,efficiency reduce construction cost.
3.Adopts wear resistant block between teeth holders due to protect teeth holder and stiffening ring from serious wearing .
