sand making machine is widely used in a variety of rock, abrasives, refractories, cement clinker, quartz, iron ore, concrete aggregate and other hard, brittle materials in the debris, crushing (manufactured sand). For construction sand, gravel roads used particularly suitable. Sand Features: The structure is simple and reasonable, since the strike-breakers, the use of ultra-low cost; unique spindle bearing is installed with advanced design, so that the machine has a heavy load and high speed rotation features. With a crushing, coarse grinding function; high reliability, tight security device to ensure that equipment and personal safety; smooth operation, low noise, high efficiency, high crushing efficiency; small affected by material moisture content, moisture content of up to about 8%; wearing parts, low loss, all wearing parts are made of high quality wear-resistant materials at home and abroad, and long service life. A small amount of wear parts made of special hard wear-resistant material, small size, light weight, easy replacement of parts. Since air circulation inside the vortex chamber, small dust pollution. Sand making machine impeller and whirl from the crushing cavity lining materials significantly reduce the cost of wear parts and maintenance workload. Production process, the stone can form a protective bottom, body wear, durable. Installation diverse, removable installation. The product was a cube, bulk density, small iron contamination. Sand can be used for stone shaping machine failure and troubleshooting Sand principle: material from the hopper into the crusher, the 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 of the three uniform impeller flow channel, the same part of the first sub-feeder surrounded by a material impact from the fall collection broken, 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 of the whirl chamber, but also 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 chances impact, friction and grinding crushing effect. The material to be broken by the lower row of the discharge port. Throughout the course of the next crushing, the material impact of mutual self-broken, not in direct contact with the metal element, but the impact occurred with the lining material, friction and grinding, which reduces the angle of pollution, prolonged mechanical wear and tear of time. Whirl chamber clever internal airflow from the circulation, eliminate dust pollution. Impact Sand material into the hopper, feed through the center hole into the high-speed rotation of the rotor after fully accelerated and thrown by the emission mouth, first with the rebound after a free-fall portion of the material were hit, then the impact to the surrounding together on the swirling vortex cavity lining material (or back on the block), the first to be bounced back to the top of the crushing chamber, the latter deflected downward movement, material and emitted from the impeller material impact to form a continuous curtain finally through the lower row of the discharge port.
