My company manufactured high-crushing machine, also known as the third pinch sand, Sand Making Machine is kind of essential equipment, various types of reference works crusher, and according to the specific use of user feedback, combined with its advantage of the design of new and efficient sand making equipment Usage: third pinch sand mainly to meet the current artificial sand industry is rod mill sand machine, impact sand machine, straight-play sand alternative. Sand machine features: the particle size is small, less dust, grain type uniform, large capacity, long life hammer, matching power smaller, three broken for secondary crushing, simple structure, stable operation, easy maintenance, etc. . Product Benefit Analysis: Investment lower than the same size of the traditional technology and equipment 50%, higher than the same scale output efficiency of traditional sand technology and equipment 40%, (in river pebbles example: a product size ≤ 5mm more than 90%). Also, the long-running maintenance costs lower than the third pinch sand the same scale traditional sand machine, widely used mechanism for sand and gravel, cement, refractory, metallurgical and other industries. Sand price new and efficient fine crusher (the third generation sand making machine) energy efficient, the small particle size, particle-type uniform, large capacity, long life hammer, matching power smaller, three broken for secondary crushing, process simplification, simple structure, easy maintenance, smooth running and so on. The third generation sand making equipment investment is less than the same size of the traditional technique and equipment 35% -50% higher than the same scale output efficiency of traditional technique and equipment 35% -50% (limestone example: a product size ≤ 5mm 85% the above). Long-running maintenance costs lower than the same size of the traditional technique and equipment 35% -50%, widely used mechanism for sand and gravel, cement, refractory, metallurgical and other industries. Sand works: material from the hopper into the crusher, by sub-feeder the material into two parts, the middle part of the sub-feeder into the high-speed rotation of the impeller, the impeller being rapidly accelerated its acceleration up to several times the acceleration of gravity, and then at a rate of 60-70 m / s projectile out from three uniform impeller flow channel, the first part of the same sub-feeder surrounded by a material impact on income falling from crushing and impact together to support the vortex chamber inner lining 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 channel material to form a continuous material curtain. Such a material whirl crushing cavity being repeated twice or even probability impact, friction and grinding crushing effect. The material to be broken by the lower row of the discharge port. And screening system to form a closed loop, three general circulation materials can be broken into 20 mesh. Throughout the crushing process, the materials themselves mutually impact crusher, not in direct contact with the metal components, but shocks and lining materials, friction and grinding, which reduces the angle of pollution, prolonged mechanical wear and tear of time.
