Automatic Sand Blasting Room
Product Introduction


Shot Blasting Room is ideal for the large-scale structures, widely used in blasting of hulls, stoves,boilers and wind power parts, etc.Large structures can move inside the Blast Room on work cars sliding on rails.

Mainly composed with the Blasting Room, Air Blasting System, Sand Circulatory System, Dehumidify System and Dust Collector.

Shot blasting room system is widely used in shipbuilding industry, military, and engineering machinery, petrochemical machinery, hydraulic machinery and bridge structures, locomotives and etc. and is suitable for large metal structure before painting surface blast cleaned and shot peening treatment .



Outstanding Advantages
  • Sandblasting chamber is strengthened by high quality corrugated board, with 4 mm rubber inner protection and independent control of LED lighting;
  • It adopts 300L sand blasting pressure system with Thomson flow valve, which can automatically circulate to ensure continuous sand;
  • Adopts screw pusher + elevator system;
  • Secondary dust filtration technology;
  • With electrical control system;
  • Using Tungsten carbide gun;
  • With sorting system;
Working Principle
Sandblasting room is suitable for cleaning and rust removal of some large workpieces and increases the adhesion effect between workpieces and coatings. Before sand blasting operation, the workpiece is sent into the sand blasting chamber, then the electric and gas devices are connected, the sand blasting lighting is turned on; Workers wear protective clothing and hold the spry gun to start the sand blasting operation. When manual sand blasting, steel shot from this process fall down to the bottom of the sand blasting chamber then the steel shot is collected by screw pusher to the bottom of the elevator, and then to the top of the sorter by the elevator belt assembly respectively. The sorter is powered by the dust collector. The purpose is to separate broken steel shot and dust from the sand blasting processing. Through the sorting device, qualified steel shot will come directly into the storage bin above the blasting machine, and ready to be used again. Dust is directly sucked away by the dust collector fan and adsorbed in the filter dust collector; finally dust falls into the dust recovery box that needs to be cleaned up regularly.
Product Description
1Sand blasting chamber

1. Sandblasting chamber is strengthened by high quality corrugated board, with 4 mm rubber inner protection and independent control of LED lighting;

2. In front of the sand blasting chamber the door is opened and closed manually. The light rail is installed on the ground. The trolley is used to transport the workpiece into and out of the sand blasting chamber.

3. 8 dust-proof and explosion-proof LED lights are installed at the top of the sand blasting chamber which equipped with a switch, it is convenient for the operator to turn on the light when observing.

4. Sandblasting start switch and emergency stop button are designed in sandblasting chamber, there are two modes: manual and automatic.

5. The maximum load-bearing limit of sand blasting chamber is 7T.

6. Sandblasting indoor specifications: 9000*5000*4000mm (L*W*H).

2Pressure tank system

1. It is composed of a 280L pressure tank, which adopts peach-shaped design to increase the fluidity of steel balls.

2. The upper part is connected with pneumatic butterfly valve and storage bin. The pneumatic valve is closed during sandblasting operation. At the end of sandblasting, the pneumatic valve opens and begins to sand the pressure tank.

3. The pipeline is equipped with manual air switch valve, oil-water separator + pressure regulating valve, pneumatic diaphragm valve, gas storage tank, exhaust muffler and sand valve.

4. 4.Equipped with two tungsten carbide guns, each gun with 10 meters sand blasting pipe.

3Steel shot elevator system

1. 1.When manual sand blasting, steel shot from this process fall down to the bottom of the sand blasting chamber then the steel shot is collected by screw pusher to the bottom of the elevator, and then to the top of the sorter by the elevator belt assembly respectively. The sorter is powered by the dust collector. The purpose is to separate broken steel shot and dust from the sand blasting processing. Through the sorting device, qualified steel shot will come directly into the storage bin above the blasting machine, and ready to be used again. Dust is directly sucked away by the dust collector fan and adsorbed in the filter dust collector.

2. Gear motor: power 2.2 kw, output speed 9.7 rpm, elevating capacity: 100 kg/min.

4Air separator system


1. A set of Air separator system with full curtain separation system has good separation effect.

2. The rear part of the air separator is equipped with a suction pipe for separating shot, sand and dust, and an internal regulating valve, which can effectively separate broken steel shot and dust in time. And so on.


5Filter dust collector MDC-12

1. Fan power: 22 kw.

2. Dust removal air volume: 23 000 m3/h, wind pressure 3400 Pa.

3. There are 12 filter cartridges with a filtering area of 10 m3 per cartridge.

4. Equipped with a secondary filter. Suitable for indoor emission, dust emission is less than 80 mg/m3.

5. With automatic backblowing cleaning device, the backblowing time interval can be set.

6. The air inlet of the dust collector is equipped with an air valve, which can adjust the air volume according to the use of the equipment.

6Electronic Control System

1. Use CHINT or Schneider brand low-voltage electrical components

2. Using Sandblasting Time Controller

3. Using ADE aerodynamic components

4. Flow detection ammeter

5. 1 set of lighting

6. 1 set of heat dissipation fans
