Not all blasting operations are suitable for open areas. Because abrasive blast material carries a risk of area contamination and standard blast cabinet size restraints limit blasting capabilities for larger objects, blast rooms are sometimes utilized as an alternative. These rooms allow for the blasting of very large or uniquely shaped objects — rail cars, for example, are far too large to be blasted in anything other than a custom engineered blast room.
DeLong Equipment offers a range of custom engineered blast rooms and facilities, available either pre-assembled or disassembled. The rooms use wheel blast technology to create a high-pressure stream of abrasive material to smooth, roughen, or clean surfaces depending on the needs of the finished product.
There are several components necessary to contain blasting processes inside a small room and to prevent contamination of the surrounding area:
• Containment — The physical structure of the room itself, a containment system is designed to remain sealed to prevent blasting material from escaping the room. Blast rooms are available in various standard forms, but our team can also design custom engineered room to meet your precise needs or space constraints.
• Blasting System — Blasting systems come in different forms and are capable of using various blasting media. Wheel blasting is the standard blasting method in all blast rooms; the system can be altered to meet an operator’s specific requirements depending on the needs of a particular project. Some systems can be ported into or out of the rooms to accommodate varying jobs.
• Dust Collection — Dust collection systems involve the flow of air through filters in the room, which remove dust from the blasting operation. These systems reduce the amount of particulate matter escaping the blast room, which creates a safer environment for the operator conducting the blasting operation.
• Material Recycling — Most rooms have a means of recycling used blasting media. The recycling method could be as simple as manually sweeping or shovelling the material to return it to the blast pot; alternatively, it could be as complex as utilizing an automated mechanical or pneumatic system installed in the floor of a blast room to fully reclaim all of the used blast material.
Many other options are available to ensure that blast rooms meet the needs of your operation.
For some projects, rooms may require additional machinery, such as overhead cranes to transport the blasting system or the work piece. Wall-mounted units capable of moving on three axes can allow the operator to reach any part of the piece with the blasting media. Sound-dampening material can also be installed to reduce noise levels. Regardless of how complex your requirements are, DeLong can custom engineer a blast room to meet them.
Blast rooms are an important component for businesses conducting blasting operations; by accommodating larger items in addition to carefully containing dust and waste, the rooms provide you with a cleaner, safer operation overall.
