Sand Making Machine,Sand Making Machine for sale

Sand Making Machine

Sand Making Machine is one of the most advanced impact crushers nowadays. It introduces high quality roller bearings like Sweden SKF and America TIMKEN, which ensure the smooth running of main unit. Personalized design is used in upper cap, sand making machine is easy and convenient to maintain and replace spare parts. Sand making machine is our sole patent using central feeding & central cascade feeding, which can be changed based on customers' needs.

The working principle of sand making machine

Material from the feed hopper into the sand making machine, the distributor sends the material is divided into two parts, one part is composed of a distributor intermediate into the high-speed rotating impeller, was rapidly accelerated in the impeller, the acceleration up to hundreds of times the acceleration of gravity, and then to 60-70 M / s velocity from the impeller three uniformly distributed in the channel of projectile go out, first with a distributor around since the receipt of a portion of the material impact of falling and breaking, together with the impact to the vortex branch cavity material lining layer, is material lining layer rebound, oblique impact to the vortex chamber top, it changes its direction of motion, deflects downward movement, emitted from the impeller material forming a continuous material curtain. Such a material dynamic crushing cavity under two times that many probability impact, friction and grinding effect in vortex. The material being broken by the lower discharge outlet. In the whole process of broken down, the material by mutual impact crushing, not in direct contact with the metal components, but with material lining layer of impact, friction and grinding, which reducespollutionangle, extend thetimeofmechanical wear. Vortex chamber internal clever air self circulation, eliminate the dust pollution.

The material into the sand making machine's feed hopper, the center feeding hole into the high-speed rotation of the rotor was sufficiently accelerated and by emission mouth out, first with the rebound after a part of the free falling impact of materials, and then with the impact to the vortex shaped material around the vortex cavity lining (or counter block), is first bounced back to the top after the crushing cavity, partial steering movement, forming a continuous material curtain and launch out from the impeller material impact, finally through the lower part of the discharge port discharge.

The use of sand making machine

  • 1, river pebbles, rocks (limestone, granite, diabase, andesite, Xuan Wuyan etc.), ore tailings, stone chip of artificial sand.
  • 2, construction aggregate, highway road fabric, cushion material, asphalt concrete and cement concrete aggregate production.
  • 3, the field of engineering of water conservancy and hydropower, highway, highway, high speed railway and passenger dedicated line, bridge, airport runway, municipal engineering, high-rise building mechanism of sand production and stone plastic.
  • 4, the mining sector front crushing grinding process, building materials, metallurgy, chemical, mining, refractories, cement, abrasive material crushing and other industries needs sand making machine.


  • 1. Advanced double pump oil lubrication system minimize the maintenance frequency.
  • 2. High precision roller bearing, smooth main unit running, and long service time.
  • 3. Hydraulic lift cap, easy and convenient replacement and maintenance.
  • 4. Overvibration alarm system is used to the sand making machine.
  • 5. Special dustproof seal system, outside powder is prevented from entering nozzles .
  • 6. Unique feeding method, change between central feeding and central feeding with cascade feeding makes rock on rock and rock on iron possible, both crushing and shaping are achieved.
  • 7. Particular material throw head design and reasonable material selection prolong the service time.
