Sand Blasting Cabinet
The Sand blasting cabinet is a closed-loop machine that allows the operator to blast the component and reuse the abrasive. Sandblasting cabinet usually consists of four components to perform surface preparation operation:
- The containment (cabinet)
- Abrasive blasting system
- An abrasive recycling system
- And the recovery system.
In the sand blasting cabinet operator placing his arms in gloves which are attached to gloves holes and blasting the component from outside of the cabinet. A vision glass is used for viewing the component and turning the blast on and off using a foot pedal or treadle.
Types of Sand Blasting Cabinet
- Pressure Blasting Cabinet
- Suction Blasting Cabinet
- Wet Blasting Cabinet
Pressure Blasting Cabinet
A pressure blasting cabinet is used where more pressure is required for the blasting process. In the pressure blasting cabinet (sand blasting cabinet) to increase the pressure of abrasive for blasting a pressure pot is used in the bottom of the cabinet.
Suction Blasting Cabinet
A suction blasting cabinet is used when more pressure is not required for blasting. The suction blasting cabinet uses compressed air to create a vacuum in a chamber. In the suction blasting cabinet, negative pressure creates in the nozzle which is used with the compressed air to directs the abrasive through a blast nozzle.
The abrasive mixture travels through a nozzle that directs the particles toward the surface or workpiece. In the suction blasting cabinet, different nozzles are used these are in a variety of shapes, sizes, and materials.
Wet Blasting Cabinet
A Wet blasting cabinet is typically used when the heat produced by friction in dry blasting would damage the component on which blasting to be done. Wet blasting cabinet is using a system that injects the abrasive + water slurry into a compressed air stream. Wet blasting cabinet is mostly used in oil and grease removed from components, and good finish develops on stainless steel.
