1. The thickened double anti-net structure fire-retardant steel core belt formed by vulcanizing integrally has the characteristic of strong tensile strength, huge impact resistance, highly tear resistance, friction resisting, long using life.
2. The transmission is simple and functional, highly safety and easy maintenance and change, using manual non-level or variable frequency speed contreller, realizing continuous and adjustable feeding volume, stable running, small noise, huge feeding amount. It is the best machine for variable coal blending operation.
