Pressure Blast Systems
Pressure Blast Systems deliver abrasives at higher velocities than suction systems. A pressure system maximizes production rates. In many applications, pressure cabinets will turn out work four times faster than units employing suction systems. In addition, they make more efficient use of air and provide the more precise control of abrasive flow required in both tough and fragile jobs. For really demanding tasks, like removing tight mill scale and finishing hard-to-reach surfaces, a pressure system is normally the only practical choice. Pressure cabinets are available in a variety of sizes, with or without reclaimers, and with dust bag or cartridge collectors. These systems are available in many custom layouts also. (see also Blast Cabinet Facts for choosing blast equipment.)
Suction Blast Systems
Suction Blast Systems cost less than pressure systems, have fewer moving parts and are more compact than pressure cabinets. Furthermore, they can blast continuously without the need to stop for media refills and they simplify the use of multiple nozzles. Although production rates are not as high, the finishes are usually comparable with those produced by a pressure system. Where initial costs and maintenance are primary concerns, suction is a good choice. Suction systems come in a variety of sizes and configurations. When recoverable media is being used, a reclaimer is advisable because it will normally pay for itself quickly in terms of reduced media waste. Also, when production exceeds two hours per day, a dust collector is preferable to a dust bag because of its greater cleanliness and efficiency. (see also Helpful hints for choosing blast equipment.)
Wet Blast Machinery
Our Wet Blast machinery uses a sealless slurry pump to agitate the abrasive and water in a slurry mixture. The slurry mixture is then pumped to the abrasive blast gun where the air pressure accelerates the mixture to the desired pressure rating. The cabinet exhaust blower and filter maintains a negative cabinet pressure and prevents abrasive from escaping the system. During operation, the fresh water window rinse assembly maintains operator visibility through the view window. The cabinet lighting is located outside the blast cabinet, and light enters through a light window located on top of the unit. This machinery is available in many different sizes and configurations depending on your production needs.
Barrel Blasters are generally designed to be used in conjunction with suction systems because they can be run continuously, or for long periods. If you are processing many parts and you want to reduce labor costs in your finishing operation, look at barrel blasters. With certain types of parts, no other finishing method can compare to these heavy-duty production machines in terms of speed and quality results. All you do is load parts in the unit, set the timer, and the barrel blaster does the rest. As parts are rotated through an abrasive blast stream, they are cleaned, finished and peened evenly and automatically. Special features include either a barrel, basket, or multiple barrel design, multiple guns, barrel controls, sizes, and custom system configuration.
Most large, repetitive blasting jobs can be handled effectively with a standard or customized Automated Machine. However, when an application is specialized, or blast equipment must be integrated with other automated links in the production process, a custom-engineered system is the only approach. We are able to analyze your specific application requirement and develop practical, efficient equipment solutions. Finishing Equipment Company, Inc., has the expertise to automate almost any industrial blast-finishing process.
Pneumatic Recovery Systems
Using low-cost, one-time abrasives in industrial blasting operations is often unnecessarily expensive. Because "economical" materials such as sand or slag break down so quickly, it is impractical to reuse them. As a result, costs for replacement abrasive, as well as the labor required to handle and dispose of it, can put a drain on your profits. With a Pneumatic Recovery System, you can now tap the cost-saving advantages of more durable media for only a modest investment. Consisting of a pressure blaster, a loading hopper, a tunable reclaimer and a dust collector, the system permits you to utilize higher quality material such as aluminum oxide, chilled iron, or steel which can be reused anywhere between 6 to 200 times.
Airless Systems work on the principle that abrasive is fed by gravity into the center of the wheel, and then fed through a regulator and distributor which controls the amount fed to the blades. The abrasive is accelerated along the flat blades of the rotating wheel where it is discharged at high velocity, both radially and tangentially, to the wheel rotation. The systems are generally simple, but as with "simple" concepts, many years of research and practical development were necessary to achieve optimum results. The installations are usually powered by electricity, and incorporate wheel impellers, blast chamber, and clean-off chamber, a dust collector and reclaimer. Airless systems can be designed in many configurations depending on your individual needs.
Standard pressure, suction, wet, or airless systems can be modified to meet your special or unique production requirements. If cabinet design, turntable configurations, gun placements, or other custom designs are needed, we have the capability to engineer a system for you. Give us an opportunity to review your special needs and present you with a custom designed system. You will be surprised at how many basic modifications can enhance and improve your production.
Blast Rooms come in many styles and sizes depending on your requirements. There are six basic components to a blast room. (1) Enclosure: Should be sized accordingly to handle the largest parts you would like to process, and be designed with a man-door and double swing doors on one or both ends depending on how your production flows. (2) Dust Collector: Should be sized to allow you ample cross draft velocity, and be permissible through your local AQMD. (3) Floor: The heart of any blast room is the floor. The least expensive system (with regards to system set-up) is a basic "sweep-and-shovel" system, which uses man-power to move blasted abrasive back to the pressure vessel. "Partial recovery" through "full recovery" floors are available either in vibratory, screw, wiper blade, or pneumatic designs. (4) Blast Equipment: Should be sized by keeping in mind the size nozzle you will be using, and the amount of compressed air you have available. (5) Air Wash Media Separator: Should be considered when using more expensive abrasive and when you would like the ability to clean and reuse your abrasive a number of times. (6) Compressed Air: Should be sized for the largest nozzle you want to use. Remember, the larger the compressor, the larger the nozzle, thus, the more abrasive you can deliver to your work.
Portable Blast Equipment
Portable Blast systems are available in both Economy and High Production Models. The Economy Models offer the ability to blast in a "pressure type" system in a non-production environment. The High Production Models are designed for use on a continuous basis. Blast pots are available in 100 lb. capacity up to 1050 lb. capacity. For the really big jobs, over-the-road units with multiple blast outlets and capacities of either 5 or 7 tons are available. For non-confined blasting, or blasting without proper protection to you and the environment, you should check with your local municipality, and or, governing bodies.
Abrasive Blast Nozzles are available for all makes and styles of both stationary and portable equipment. Nozzles are available in many styles and sizes incorporating the latest technology in design. Nozzle liners are available in the following materials: Ceramic, Tungsten Carbide, Silicon Carbide, and Boron Carbide.
Hose, Tank, and Nozzle couplings are available in aluminum, brass, steel, or plastic construction. We inventory couplings to fit 1/2" I.D. hose through 1-1/2" I.D. hose.
Abrasive Blast Hose
Abrasive Blast Hose is available in 2 ply (1/2" I.D.) or 4 ply (3/4" I.D. and larger) construction. Our hose is made to withstand the hazards encountered in blasting. The inner tube resists abrasion, and the flexible outer cover is easy to handle, yet stands up to external abuse. Our hose incorporates specially compounded carbon black that dissipates electricity directly to the ground for the life of the hose. When specifying blast hose, the I.D. should be approximately 3 to 5 times the size of the nozzle orifice to assure efficient operation and prolong hose life.
