Abrasive Blast Systems- Products

Blast Rooms

The core of any modern abrasive blast system is the blast room. Confining the blasting operation to a controlled, clean environment enables efficient abrasive recycling. Well designed blast rooms consist of an amply lit work area, an abrasive reclaim floor that begins the recycling process, an abrasive transport and separation system that removes trash while returning clean abrasive to the blast tank and a dust collector for keeping the environment clean and contaminant free.

Our common sense approach to designing a blast room begins with understanding the size of the items that will be blasted. The blast room should be large enough to accommodate the largest work piece and provide ample room for the blasters to work. Since blast room size is proportional to dust collector airflow capacity (and the cost of the dust collector), correctly sizing the room is a key factor in cost effective design.

The next consideration is the anticipated production demand on the operation. High volume production 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.

Production volume and work piece handling requirements dictate the room configuration selection. High volume rooms will benefit from a flow through design with overhead monorail or in floor material handlers. Light to medium volume operations can take advantage of more cost conservative in/out designs.

Our high standards for design, material selection and workmanship ensure all of our systems are built-to-last. All of our blast rooms include the following quality features:

• Reinforced structural steel abrasive storage hopper with easy access for cleaning and maintenance
• Highly selective rotary drum + air-wash abrasive separator
• Heavy Duty 9" diameter return augers with 3/8" thick flighting
• Gravity fed blast tank with stop-leak plates to prevent leakage during tank exhaust
• Ten gauge (minimum) steel plate on all abrasive collection assemblies, roof and wall panels

Reclaim Floor Designs

We offer a variety of reclaim floor designs and room configurations which allows us to design a blast room facility uniquely tailored to meet the economic and production concerns of our customers.

Single Screw Partial Reclaim System
A single screw partial reclaim system is the most economical floor design we offer. This is a basic reclaim system that is best suited for low to medium blasting production levels. This System can be expanded into an H-shaped or U-shaped of full floor reclaim system as production demands increase.

H-Shaped Partial Reclaim System
The H-shaped floor design is typically employed in a flow-thru room configuration where heavy work pieces or material handling devices can drive into the room and position the work piece on the steel covered concrete floor located between two longitudinal reclaim screws. The position of the screw assemblies allow the abrasive delivered from the blasting nozzle to strike the side walls and fall into the screws for reclamation. Approximately 60-90 percent of the blast media is recoverable during the blast operation in an H-shaped partial reclaim system. The abrasive media remaining on the floor is can be swept into the metered shed plate screw at the end of the shift.

U-Shaped Partial Reclaim System
The U-shaped floor design is utilized in an in-out room configuration where heavy work pieces and material handling devices can drive into the room and position the work piece on the steel covered concrete floor located between two longitudinal reclaim screws. The key difference between the U shaped reclaim floor and the H shaped reclaim floor is the position of the cross screw along the back wall of the blast room.

Full Floor Reclaim System
The full floor reclaim system uses multiple reclaim screw assemblies to create a high volume abrasive reclaim system that recycles 100% of the blast media during the blasting operation. Full floor reclaim design requires that the material handling of the work be intricately designed into the configuration of the room. Work piece material handling options include work car/track system, an overhead monorail crane, an overhead bridge crane, or heavy duty floor grating with support steel.

Dust Collectors

The dust collector is an essential component of an abrasive recycling system. It removes small particles contaminants from the abrasive media and cleans the air in the room for particle emission pollution compliance.

The cost of the dust collector is proportional to the cubic foot per minute (CFM) air movement capability of the system. The CFM of the system depends on the room size and the blast abrasive being used.

Our cartridge dust collectors meet the most stringent guidelines for particle emissions, provide cleaning efficiency of 99.999% and filter particles down to .5 micron.

The pulse jet cleaning system automatically cleans the filter elements while the collector is in operation, eliminating production down time for filter cleaning.

Optional Equipment

We offer a variety of optional blast room equipment further enabling flexibility in meeting your requirements for blasting.

Rubber Roll-Up Door
Pre-assembled powered rubber door constructed of 3-ply neoprene, ideal for tight work spaces. (See Image to Right)

Overhead Material Handling
Work piece transport and handling systems designed for high volume or special material handling needs. Monorail cranes and overhead bridge cranes with manual or tractor driven trolleys may be used in design.

Work Car Assembly
Manual or pneumatically driven work cars offered in a wide range of sizes and load capacities.

Magnetic Separator
Allows for a dual abrasive media operation by separating ferrous and non ferrous abrasives.

Side Entry Door Assembly
Material handling solution for tight work spaces or systems that require work flow directional change.

Paint Filter Bank Assembly
Combination blast and prime facility which includes filter housing, filter elements, fan, pressure differential gauge, exhaust stack and weather cap. A 10-gauge steel door protects the filters during the blasting operation.

Brush Steel Assembly
Provide an abrasive tight seal around chain from the overhead material handling hoist. Includes guide rails to center hoist chain and adjustment bolts for the brushes

Portable Equipment

We offer a self-contained abrasive reclaim system that includes an integral elevator, separator/classifier, dust collector controls and abrasive storage hopper. Rugged tubular steel frame construction enables easy transport to the work location. We also offer custom engineered portable units.

The P-RAM 50 is a self contained, weather tight, high production abrasive reclaim module with the ability to clean 160 cu. ft. of dry abrasive per hour.
