Stone shot blasting machine with conveyor for cement tiles, marbles and natural granite
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.
Features of Shot Blasting Machine:
- Automatic PLC control, save labor cost;
- Perfect of finishing consistency of marbles surface roughnessing, retexturing, anti-skiding, and outwall decoration;
- Continuously feed for stone, marbles, etc.
- No pollution for the environmental protection;
Applications of Shot Blasting Machine:
- Marble, Blocks, Bricks, Tiles, Kerbstones, Slabs & Cement: Stone surface roughness, anti-skid, retexturing, decoration;
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;
2. Shot Blasting Room:
- Shot blasting room design with CAD (Computer Aided Design) reach of best blasting angle and distance;
- Blasting room made of strong profiles and 10mm plates;
- The direct-blasting hot area use of upgraded wearing-resistance manganese casting steel with 35-45 HRC;
- The input and output use rubber bands for sealing;
- Labyrinth structure to keep the abrasive leak;
3. Roller conveying system:
- The roller conveyors with manganess liners for longer lifespan;
- Steel continuous roller conveyors for the long-size and heavy-duty marble, stones, etc.
- Rubber belt conveyor for small-size and light-duty tiles, bricks, slabs, etc.
- Bearing support with the labyrinth shape prevents leaking of the steel media;
- Standard capacity is 1,000kgs per meter;
- VFD (Variable Frequent Drive) for motor to adjust of the input & output feed speed;
