Silver City, Gansu Province is a prefecture-level city in central Gansu Province, located in the Loess Plateau and the Tengger Desert in the transition zone. Jurisdiction silver, Hirakawa two districts and Jingyuan, Jingtai, Ning three counties. City Hall in the silver area. Material from the hopper into the crusher, the sub-feeder the material is divided into two parts, sub-feeder from middle to high-speed rotation of the impeller, and is rapidly accelerated in the impeller, its up to several hundred times the acceleration of gravity, and then at a rate of 60-70 m / s projectile from the impeller flow channel in three out of uniform, the first part of the material with the impact of the feeder surrounded by self-closing falling broken, www.hyzhishaji.com then went to the impact of the vortex chamber support on the inner lining material is the material lining rebound oblique impact on the top whirl chamber, and to change its direction of motion, deflected downward movement, emitted from the impeller material to form a continuous material curtain. Such a material in the whirl crushing cavity by two or even several times the probability of impact, friction and grinding crushing effect. The material to be broken by the lower row of the discharge port. In breaking down the whole process, the material on their own mutual impact crusher, not in direct contact with the metal components, but the impact of the occurrence and lining materials, friction and grinding, which reduces the angle of pollution, to extend the mechanical wear and tear of time. Whirl ingenious internal cavity airflow from the circulation, eliminating the dust pollution. Mingde Zhengzhou Mining Machinery Manufacturing Co., Ltd.
