Blast Room

A blast room is a completely enclosed, engineered facility designed for industrial sandblasting and surface preparation of large components. It delivers a controlled environment in which abrasive blasting machine operations are conducted safely, efficiently, & with minimal environmental impact.

Unlike standard cabinets, a blast room allows operators to work inside the enclosure, creating it excellent for heavy structures, fabricated assemblies, tanks, pipelines, and large machinery.

Built for demanding industries such as manufacturing, EPC projects, shipbuilding, and infrastructure, our blast room systems deliver consistent surface grade while optimizing productivity & compliance.

Blast rooms deliver operators with a safe, efficient, clean, and environmentally agreeable working environment during surface treatment or blasting of other machines. It provides protection for operators against harmful sand blasting dust collectors. Abrasive media could be recycled and reused, utilizing the blast room during surface preparation. This is one of the safest & most efficacious methods.

Why Choose an Industrial Blast Room?

• Controlled & Dust-Free Environment: A blast room integrates a high-efficiency dust collection system that captures airborne particles, ensuring clean air, regulatory compliance, and operator safety.

• Superior Surface Preparation: Using high-velocity abrasive media, the blast room releases rust, scale, coatings, or contaminants, preparing surfaces for painting, coating, or welding.

• Media Recycling & Cost Efficiency: Advanced recovery systems allow abrasive media to be collected, cleansed, and reused, significantly reducing functional costs.

• Scalable for Large Components: Blast rooms are engineered for oversized or complex workpieces that cannot fit into standard blasting cabinets.

How a Blast Room Works

A blast room is a completely integrated system designed to deliver high-performance surface preparation through abrasive blasting, media retrieval, and dust control. Engineered for continued procedure, it assures maximum productivity, tiniest waste, and consistent surface quality for extensive industrial elements.

A blast room operates as a closed-loop industrial system designed for continuous surface preparation, abrasive rescue, & air filtration. Below is a step-by-step explanation with process visuals to clearly understand how it works.

Working Principle of a Blast Room

A blast room operates on a closed-loop process, where abrasive media is continuously utilized, recovered, cleansed, and reused. This ensures cost efficiency and environmental compliance while maintaining excellent blasting performance.

Step-by-Step Blast Room Process

Abrasive Blasting

The process begins with abrasive blasting, where compressed air propels abrasive media (such as garnet, steel grit, or sand) through a high-performance sand blasting nozzle onto the work surface.

• Releases rust, scale, paint, and contaminants
• Creates a uniform surface profile for coating adhesion
• Assures consistent and high-quality surface preparation

Surface Cleaning & Preparation

As the abrasive impacts the surface, it instantly eliminates unwanted layers and impurities.

• Produces a clean, roughened surface
• Improves coating bonding strength
• Enhances durability and corrosion resistance

Abrasive Collection System

After impact, the abrasive media utilized falls to the blast room floor and is assembled through an integrated recovery system.

• Floor-based collection (manual or automatic)
• Screw conveyors or vacuum recovery systems
• Eliminates manual handling and material loss

Media Separation & Cleaning

Collected abrasive is transferred to a separator unit, where it is cleaned and classified.

• Removes dust, fines, and broken particles
• Retains only reusable, high-quality abrasive
• Ensures consistent blasting efficiency

Abrasive Recycling

Cleaned abrasive is stored & recirculated back into the blasting system.

• Deflates abrasive consumption
• Lowers operational costs
• Boosts continuous blasting operations

Dust Collection & Air Filtration

A high-efficiency dust collector system captures airborne particles generated during blasting.

• Maintains clear visibility inside the blast room
• Protects operators and equipment
• Ensures compliance with environmental standards

Components of the Blast Room

A blast room is built by combining different parts. The main parts of the blast room include:

• Dust collector (reverse pulse jet pleating)
• Bucket elevator and media separator
• Portable sand blasting machine P7 (750 R)
• Metal blast room system
• Metal door & Light
• Rubber coating
• Cart and track
• Carry protection

Metallic Blast Room System

The metallic blast room system is also known as the blast room "chamber". It is made from an MS sheet that delivers the necessary strength and rigidity to the chamber. The size of the chamber relies on the applications to be carried out within the chamber. The proper design & layout of the structure is done prior to the construction of a chamber. Various panels are prepared with MS channel support for more useful support and rigidity. The entire blasting or surface preparation process takes place inside the chamber.

Rubber Coating

During surface preparation or sand blasting machine, an assortment of abrasive media is utilized. These abrasive media are released into the air during blasting and could cause damage to the blast room and the operator. Rubber liners have been installed on the blast room walls to protect both the blast room walls and the operator. This rubber lining covers every wall in the blast room with a thickness of up to 3mm. Here, strips made by MS are provided with each rubber sheet.

Metallic door

In a blast room, a door is made of sheet metal. The blast room doors are equipped with vision lenses so certain the operator can get a proper view to observe the blasting operation inside the blast room. These metal doors have louvers so air can pass through them. In the absence of these grids, a vacuum would be created within the blast chamber that could damage it.

Dust Collector

In the blast room, surface preparation or shot blasting produces an extensive amount of dust particles that must be separated. These dust mites are very harmful to operators and can cause numerous illnesses when exposed to them. To remove these dust particles from the blast room, a dust collector system is installed so that unwanted dust could be removed. Various types of dust collectors can be utilized for this purpose.

The main parts of the dust collector are:

• Blower
• Dust collector system
• Dust removal system

The blower is used to move the dusty air to the dust collector, from where they can be separated. Above the blast room, a blower is installed through which all dust particles released after blasting are brought into the dust collector for removal. The dust collector system includes the function of a pleated bag. Dust particles entering the dust collector are trapped in the pleated bag. Blasting is done under high pressure to remove dust from these pleated bags.

In a dust removal system, all dust particles are removed from the dust collector. A sudden shock generated by high-pressure air in a pleated bag causes an expansion wave. Folding the bag breaks up the powder cake on top of the pleated bag. And all the dust particles are collected in a tank from which they are separated.

Reverse Pulse Jet Pleated Bag Dust Collector

Reverse Pulse Jet Pleated Dust Collectors use pleated bags to remove dust particles from where they are separated from the blast room. All the dust particles from the blast room enter the dust collector. They get stuck in the pleated bag of the reverse pulse jet dust collector. When assembled, they provide a completely dust and pollution-free working environment. It consists of six folded filters, each of which is connected to a solenoid valve. The solenoid has a sequential timing controller that controls the operation of the solenoid valve. The solenoid valve works on the pneumatic principle. Power wires are connected to the solenoid valve, and when air enters one end of the solenoid, a timer is set for 10 seconds, after which air from the cylinder enters the dust collector and is stored in an SS tank. from where it is removed.

In reverse pulse jet pleated bag dust collector, the dust particles trapped in the pleated bag are exposed to high pressure due to blasting. This high pressure generates a sudden jolt that causes the ripples in the pleated bag to expand. As a result, the powder cake breaks down and accumulates in a tank. It should be ensured that the wave generated by the compressed air travels throughout the pleated bag in order to prevent the dust cake from being properly vented, so that all dust particles can be removed.

Reverse Pulse Jet Pleated Bag Dust Collector Features:

• Easy to operate and handle.
• Easy to remove pleated bags
• The installation process is simple.
• Requires low air consumption.
• High filtering efficiency

Reverse Pulse Jet Pleated Bag Dust Collector Application

• Shot Blasting / Shot Blasting Machine

• Quarters of a Pint
• Metallic Paint Booth
• Metals and Minerals

Bucket Elevator and Media Separator

When the blasting operation is carried out in the blasting room, residual dust particles and abrasive media may be suspended in the air, or some of them may fall to the ground. They need to be separated from the blast room. This dust collector is used to remove them. A bucket elevator is used to transfer these particles from the blast room to the dust collector. Bucket elevators help to lift these dust particles with the help of conveyor belts. With the help of a conveyor belt, the dust particles and abrasive media are reduced by gravity and then passed to the media separator through the action of the motor. From the bucket elevator, the abrasive media and dust particles are transferred to the media separator.

Media separation helps to separate the abrasive media from the heavy dust particles. After separating the abrasive media from the dust particles, the media separator transfers the abrasive media to the P7 (750R) portable sand blasting machine. In this way, the medium can be reused in a portable sandblasting machine for other processes to be performed on the machine.

Blast Room P7 (750 R)

In a blast room system, a portable blast machine is positioned outside the blast chamber to facilitate blasting using manual blast hoses. It must have a tungsten carbide jet nozzle. A portable sandblasting machine is easy to move from place to place as it has wheels with which it can be easily transported to any job site. It is used to remove dust and rust from the metal surface and provides a smooth surface finish. The selection of abrasives on the portable sandblasting machine should be made according to the application.

For example, if the abrasive medium particle is harder than the metal surface, it may damage the surface and scratch it; Therefore, soft abrasive media should be used for this type of surface. The compressed air, together with the abrasive medium from the compressor, is expelled at high pressure and speed through a jet hose over the metal surface, and all contaminants are removed.

The P7 (750 R) is a remote-controlled portable sand blasting machine. Therefore, the machine can be operated by remote control easily. The machine is provided with a remote control valve at the end of the nozzle by means of which ON / OFF operations can be performed easily and automatically. A dead handle is placed on the remote control system. When the deadman handle is activated, the blasting operation is performed, and when the deadman handle is released, the blasting operation is stopped. The blast hose of the portable blast machine enters through the door into the blast room chamber.

Illumination

In a blast room system, when the blasting operation takes place, residual dust particles and abrasive media are released into the air, giving the operator inadequate visibility. Lighting has been provided in the blast chamber to provide adequate operator visibility. Wire mesh protected against light lies in the blast room. The intensity of the light inside the blast room should be between 300 and 400 LUX for better vision.

Control Panel

On a control panel, the phase indicator indicates the phase, and the push button is used for on/off operation. The ammeter and voltmeter are used to measure current and voltage. Emergency switches help to stop the entire system in an emergency with a single switch. A sequential timer is connected to control the solenoid valve on the dust collector.

A control panel of a blast room system contains all the operational controls. Like:

• Phase indicator (R / Y / B)
• Push button (R / G)
• Ammeter / Voltmeter
• emergency switch
• Double starter
• Sequential timer

Trolley and Track

In a blast room system, the workpiece, metal surface, or any job to be shot blasted is brought into the chamber with the help of a provided cart. The workpiece can be heavy and oversized. It will be difficult for the workers to bring them to the chamber. Proper rail and rail arrangements have been made to avoid any damage before and after the blast. Therefore, a carriage and rail system is used to move the workpiece before and after the blasting operation is carried out within the blast chamber to avoid any damage.

Safety Wears

Blasting safety wear an important role in any industry. To protect them from any physical damage, the operator must take adequate safety precautions. Every operator must wear safety clothing while performing any operation in any industry. In a blast room system, during any operation, a large amount of dust and abrasive media are released into the air, which can affect the operator in a harmful manner. Operators must be fully equipped with protective clothing prior to carrying out blasting or any other operation within the blast room.

They must have a sufficient amount of fresh, filtered, breathable air so that they can easily survive the working conditions. This will help them to achieve a comfortable working environment.

An appropriate set of safety clothing should include:

• Air-fed Abrasive Blast Helmet
• Sand blasting hose from the machine to the operator
• Helmet Air Conditioning
• Hand gloves
• Wellington
• Respirator
• Operator Protection Suite
