Stone shot blasting machine with conveyor for cement tiles, marbles and natural granite

granalladoras granallado para piedras natural o artificial, cemento, granito, mármol

    SGT series is a new range of automatic turbine Stone shot blasting machine for the surface superficial treatment (roughening, glazing, distressing, etc.) of marbles wall-decorative, slabs of natural marble or agglomerate, granite, as well as cement tiles, interlocking paving, curb-stones, etc. Exposure to the abrasive impact brings out the mineral components in the concrete, tile, and granite, etc., and gives the surface a special appearance, anti-skidding of the road surface or decorative wall of the house.

    Pieces are continuously transported on a horizontal, netting, or rubber conveyor belt; the blasting effect is obtained through the centrifugal projects (without compressed air) of spherical shot abrasive to top-surface or both surfaces. The parts to be treated will be placed on the network in the entrance area manually or with automated systems.

    Vary the speed by transportation or of shot projection controlled by Variable Frequency Drive (VFD), according to the effect desired or to the hardness of the surfaces to be treated.

Applications of Shot Blasting Machine:

Characteristics of Roller Conveying Shot Blasting Machine for stones:

1. High efficient of Shot wheel Turbines

  • Compact shell structure, longer lifespan of blades, lower maintenance;
  • Upgraded wearing-resistance with low working noise & vibration;
  • High-speed blasting capacity with more recycle abrasive using;
  • Optimal blasting angle, velocity and energy-saving;
  • Top side of coverage, only upper side cleaning;
  • Stainless steel abrasive is prefer for the marble surface roughness;
  • VFD (Variable Frequent Drive) for motor to adjust of the shot projectile capacity;
