"Three high agriculture" booming, litchi, banana, longan and other "Lingnan good fruit" famous, is China's fruit production base, aquaculture prestigious is the "Chinese tilapia capital." Sand is suitable for crushing soft or medium hard and extremely hard materials, sand widely used in large, smelting, building material, highway, railway, water conservancy and chemical industry and many other sectors. Material from the hopper into the crusher, the sub-feeder the material is divided into two parts, sub-feeder into the middle of the high-speed rotation of the impeller, the impeller being rapidly accelerated its acceleration up to several hundred times the acceleration of gravity, then at a rate of 60-70 m / sec projectile from the impeller flow channel in three out of uniform, the first part of the material with the impact of the sub-feeder from around since broken down, www.hyzhishaji.com then with the impact of the vortex branch cavity the inner liner material is the material lining rebound oblique impact on the top of the whirl chamber, but also to change its direction of motion, deflected downward movement, emitted from the impeller material form a continuous material curtain. Such a material whirl broken twice by the cavity and repeatedly hit probability, friction and grinding crushing effect. The crushed material from the lower discharge port discharge. Throughout under the crushing process, the material on their own mutual impact crusher, not in direct contact with the metal element, but with a lining material impact, friction and grinding, which reduces the pollution angle to extend the mechanical wear and tear of time. Whirl ingenious internal cavity flow from circulation, eliminate the dust pollution. Minter Ellison main production facilities include: Sand, sand machine, sand making equipment, river pebbles sand, pebble crusher, roll crusher system and so on.
