A Shot Blasting Cabinet is a chamber of mild steel sheets that provides high-pressure sand/shot or grit blasting. It provides safety to the worker who is blasting the job. It offers an environmentally friendly blasting process because it collects all the media by blasting to the Dust Collector. Shot Blasting Cabinet is well known for reusable abrasive media that provide reliability and high performance. The heavy particle of media that is reusable fell down into the hopper through the perforated sheet. We use an air compressor for compressed air and that compressed air creates pressure in the pressure pot.
We generally recommended a 5mm blasting nozzle for shot blasting and the nozzle sizes vary on the sizes of abrasive media. We use various types of abrasives in the Pressure Blasting Cabinet according to the requirements of blasting like for sandblasting we use river sand and Abrasive Garnet Sand, for shot blasting we use Steel Shots, for granite engraving we use grit abrasives, and so other blasting process uses the abrasive media to follow their needs.
We offer these models of shot blasting cabinets and the specifications table are:
| Model No. | Height | Width | Depth | Storage Capacity Lit. (CFT) |
| MB 6060 | 600 | 600 | 600 | 28(1) |
| MB 9182 | 775 | 910 | 820 | 28(1) |
| MB 12090 | 900 | 1200 | 900 | 42(1.5) |
| MB 150120 | 900 | 1500 | 1200 | 42(1.5) |
The working and usability of Shot or Sand Blasting in the Pressure Blasting Cabinet is very simple and easy. It is operated on high pressure for blasting in the cabinet so we don’t need to be wary about the reusability of abrasive media and air pollution. First, we choose the suitable abrasive media according to the metal part or job for blasting. That media is loaded into the hopper by the perforated sheet and wire mesh. The hopper is connected to a pressure pot through a flange and rubber sheet.
Then abrasive media like Copper Slag, Aluminum Oxide, and Cut Wire Shot goes into the pressure pot. And the second step is to start the air compressor. After turning on the compressor we open the ball valve that passes the compressed air into the air Filter-Regulator(FR) Then compressed air goes into the solenoid valve and it stops the air that is connected to the footrest switch and when we press the footrest switch solenoid valve releases the air and the air goes into the mixing tube and pressure pot through NRV.
After that, the mushroom valve lifts up from high-pressure air and then creates pressure in the pressure pot. Then the abrasive goes into the mixing tube and is thrown into the blasting hose and blasting nozzle by high pressure. After doing all steps properly blasting is started in the cabinet through the blasting nozzle. We also turn on the dust collector as soon as the blasting starts so that the fine dust goes into the industrial dust collector. The dust collector is fitted with a blower that is connected to an electric motor that collects the fine dust from the cabinet and collects it in the fabric bag. On the outside of the dust collector, we provide a shaking handle that shakes the fabric bag so that all the dust gets collected in the dust tray.
As a leading Sand Blasting Machine and Shot Blasting Machine Manufacturer in India, we design and build durable and high-performance blasting machines, cabinets, Blast rooms, and their equipment. Firstly we prepare the structure of the pressure blasting cabinet according to the customer's requirement. We use high-quality MS sheets for making cabinets, doors and dust collectors and all of them range in size from 1.5mm to 3mm. We take a rectangular mild steel sheet which is cut by a laser cut machine according to the structure of the cabinet and dust collector.
Then with a bending machine, those cut parts are bent and joined by ARC welding. Inside the cabinet, we put a 2.5mm thick rubber sheet, which protects the cabinet from damage during blasting. After joining all the bent sheets by welding, we do their grinding and polishing and then paint. After that, we make a pressure pot that is 6mm thick. We make a pressure pot in 3 steps first we make a d-sent then we make a pressure tank and finally hopper.
To increase the strength of the pressure pot, we weld these parts both inside and outside. Inside the pressure pot, we put two GI nipples, the first GI nipple which is 3/4 inch in diameter connected horizontally through the socket, and the second GI nipple which is 1/2 inch in diameter is connected to the horizontal nipple by a reducer elbow. After that, we install a mushroom ball on the vertical GI nipple. We make a mushroom ball from alloy and aluminum.
We connect an air hose to the air compressor, then through a connector, we connect it to a ball valve and then to the FR so that the moisture that is with the air is separated. After that, we install a 220v solenoid valve and connect it to a footrest switch or selector switch. After the solenoid valve, we put an NRV (Non-Return Valve) so that the media from the pressure pot does not come back to the air compressor. At the bottom of the pressure pot, we put a mixing tube in which the abrasive media and compressed air mix, and further blasting start with the blasting nozzle through the blasting hose. Before delivering the blasting machine, we check it properly and we sell only the best quality machines to our customers. We are well-known for making a Shot Blasting Machine at the best and most affordable price.
