Independently of the data all our Abrasive-blasting cabinets machine have in common that they are universal applicable in the working as well as the blasting materials application. To achieve the optimum blasting result.
A blast cabinet is essentially a closed loop system that allows the operator to blast the part and recycle the abrasive. It usually consists of four components; the cabinet, the abrasive blasting system, the abrasive recycling system and the dust collection. The operator blasts the parts from the outside of the cabinet by placing his arms in gloves attached to glove holes on the cabinet, viewing the part through a view window, turning the blast on and off using a foot pedal or treadle. Automated blast cabinets are also used to process large quantities of the same component and may incorporate multiple blast nozzles and a part conveyance system.
There are three systems typically used in a blast cabinet. Two, suction and pressure, are dry and one is wet:
Types Of Blasting Cabinets :
Suction/ Vacuum blasting cabinet
A suction blast system uses the compressed air to create vacuum in a chamber (known as the blast gun). The negative pressure pulls abrasive into the blast gun where the compressed air directs the abrasive through a blast nozzle. The abrasive mixture travels through a nozzle that directs the particles toward the surface or workpiece.
Nozzles come in a variety of shapes, sizes, and materials. Tungsten carbide sand blast Nozzle is the liner material most often used for mineral abrasives. Silicon carbide sand blast Nozzle and boron carbide sand blast Nozzle are more wear resistant and are often used with harder abrasives such as aluminium oxide, silicon oxide .
Pressure blasting cabinet
In a pressure blast system, the abrasive is stored in the pressure vessel then sealed. The vessel is pressurized to the same pressure as the blast hose attached to the bottom of the pressure vessel. The abrasive is metered into the blast hose and conveyed by the compressed gas through the blast nozzle.
Wet Blasting Cabinets
Wet blast cabinets use a system that injects the abrasive/liquid slurry into a compressed gas stream. Wet blasting is typically used when the heat produced by friction in dry blasting would damage the part.
Automatic Abrasive Blasting Cabinet Type Machine
- Rotary Indexing Blasting Machines :
The machine works on suction blasting principle as a suction blaster. Blast cabinet is fitted with a bearing mounted indexing turntable, with number of indexing positions. One indexing satellite stands outside the blast cabinet for job loading and unloading while other satellites stands inside the blast cabinet. (One in blasting operation and others are in queue) the indexing turntable is driven by a geared drive. It has indexing movement i.e. after 90 degree or specified rotation, the turntable stops in such a way that satellite having work piece, comes under the blasting area.
After the required finish is obtained, the indexing table rotates again by specified degree so that the next satellite having new job for blasting to come under the blasting area and blasted job comes to loading and unloading area
- Roll Etching Blasting Machines :
These machines provide required roughness /etching on rolls used in the rolling mills. The machine operates on the direct pressure principle of abrasive blasting & fully automatic in operation. The machine has blasting chamber, horizontal nozzle reciprocation arrangement, motorized work car, track extension with roll rotation arrangement, reclaimer unit and dust collector.
- Tyre Mould Cleaning Blasting Machine :
The machine consist of Blast Chamber with Turn Table & Abrasive Recovery Unit & Dust Collector 1 Nos. of Suction Blast Nozzle The machine is having Track mounted trolley with Rotary Turntable. The Turntable can move in and out from Blast Cabinet through Motorized Winching Arrangement. The Turntable is equipped with suitable Fixture for holding Tyre Mould on it.
- Geyser Tank/ Boiler / Cylinder ID Cleaning Sand Shot Blasting Machine :
Blast cabinet is fitted with a bearing mounted rotary turntable, dust Collector , blasting hopper and lance for internal blasting of Geyser or Boiler . Shot blast lances able to clean inside the static boiler by static angular nozzles.
