Industrial sand blasting room are a productive method to prepare large components while providing a safe environment for the operators and co-workers. Blast rooms are large blasting systems for handling work pieces too large or complex for even the largest blast cabinet. An operator, outfitted in appropriate PPE (personnel protection equipment), is inside the blast room maneuvering around and blasting the work piece.
Blast rooms can be designed to fit the application, part size, production rates, types of abrasives to be used, and the workflow of the finished parts.
Main compositions of sandblasting room
Sand blasting chamber
Abrasive recycling system(floor recyle system, elevator, separator, bucket elevator, abrasive storage hopper)
Lighting system
Dust Collector
Steel grating
Material handling system
Electric control system
Part 1: Sandblasting Chamber
Consists of the entire physical structure and closing the entire abrasive blast operations. And it’s typically made of structural steel and steel cladding or sandwich panel steel, to protect the steel walls and ceiling and to assist with sound dampening pliable lining resistant to abrasive blasting, such as rubber or polyurethane is used for lining the entire interior surface of the blast chamber, key elements to consider for any blast chamber design include doors, lighting, ventilation, and work handling to drive the ventilation of a blast chamber, we require a dust collector.
Get the right size
Make sure the blast room is the right size, Make sure you give your parts and your operator plenty of room. For example, if the parts you need to blast are very tall, consider adding some additional height to the cabin so you won’t constantly be blasting into your light fixtures or the unprotected ceiling surface. Also, if the part you want to blast takes up the majority of the cabin, give your operator extra width and length to safely work around the part without standing in a stream of blasting media bouncing back towards him
Part 2: Blast Pot( also referred to as a blasting pot, pressure pot, pressure vessel, media blaster or portable blaster)
a.Portable Pressure Pot Sandblaster is powered with compressed air, the abrasive media is accelerated to 50-60m / s impact to the workpieces’ surface, it is a non-contact, less non-polluting method of surface treatment.
b.Portable Pressure Pot Sandblaster
c.The system is installed with 1-2 pcs peach-style pressure tank and designed to increase steel grit fluidity.
d.The upper part is connected with a pneumatic butterfly-style valve and a storage bin. The pneumatic valve is closed during the blasting operation and opened to input shots at the end of the blasting.
e.The pipeline is equipped with a manual air on-off valve, oil-water separator, pressure regulator, pneumatic diaphragm valve, gas storage tank, riot device, exhaust muffler and sand valve etc.
f.2 or more tungsten carbide blasting guns, with a long sandblasting hose connected to each gun.
Part 3: Abrasive recycling system
The next consideration in the design of abrasive blast rooms, is the anticipated production demand on the operation. High volume production abrasive blast operations with multiple blasting work shifts per day will require a full reclaim floor design and a specialized material handling system. Lower volume operations can use one of our partial reclaim systems.
Semi-automatic recovery
Sweep-In Reclaim System
Single screw reclaim system
U type reclaim system
H type reclaim system
Fully automatic recovery
The full floor reclaim design requires that the material handling of the work piece be intricately designed into the configuration of the room. The full floor reclaim system involves multiple screw assemblies covered by a grating. The full floor reclaim design can be used with any room configuration. This abrasive blast reclaim system is well suited for pass-thru and/or high production requirements.
Part 4: Dust Collector
The media reclamation system does not move enough air to effectively remove airborne particulate from the enclosure. So, an operator using a typical reclaim unit won’t be able to see what he’s blasting unless the blast room also has a second system designed to filter the air inside the room.
The most popular dust abatement systems use cartridge type filters. The filters are much longer lasting and can be set up to automatically self-clean using compressed air. These abatement systems usually have a large waste bin located under the filters, and the collected dust and debris falls from the filters into the bin during cleaning, so they may also be considered dust containment systems. The collected dust and debris is usually removed manually by the operator, but upgraded models exist which include a pump that transfers the dust and debris out of the collection area.
Part 5: Programmable Logic Controller
All process parameters of work pieces blasting can be configured and saved in PLC control unit, in the result that repeat input, repeat pushing different buttons are completely unnecessary. This means, much shorter time of parameter configuration, much less working hours of operator and high efficiency.
Part 6: Personal Protective Equipment(PPE)
Professional quality safety gear can actually help operators be more productive, so it pays for itself fairly quickly. It usually includes protective wear, a helmet and respirator, and a good air filter system. Although it looks cumbersome, once an operator adapts to using this type of gear he is almost always working faster because he doesn’t have as many safety concerns and he can see what he is doing while working near the surface he is cleaning. This is especially true when dealing with detail work that requires a close-up view.
Not only can safety gear increase throughput, it helps reduce liability and prevent injuries to your employees. Safety gear is a win/win for your shop and employees and it’s an option we strongly recommend.
