Aluminum Oxide (Blast Cabinet Abrasive)

Aluminum Oxide (Al2O3) is an excellent media for use in blast rooms or blast cabinets, where the grit is contained for re-use (up to 30 or more re-uses). Synthetic (man-made) Aluminum Oxide is a silica free inert compound, with a tough crystalline structure, and a uniform hardness of 9 on the MOHS scale (Diamond is 10). These properties combined with uniform particle sizing provide high-speed production with excellent visibility (very low dusting), and lower air requirements (60 to 80 psi recommended). Unlike most other blast media, which are natural or by-products, synthetic AO has uniform properties without random natural weaknesses, making it the most widely used abrasive in the world. When using aluminum oxide for blasting, it is strongly recommended to use tungsten or boron carbide nozzle.

Econoblast "E" - Aluminum Oxide (Blast Cabinet Abrasive)

Econoblast^TM Aluminum Oxide (recycled) -- Blend of precisely graded, high purity white, pink, ruby, and sintered aluminum oxide grains, which are normally much too expensive to be used for pressure blasting. Econoblast^TM is one of the fastest cutting abrasives, and is highly recyclable, reducing time, cost, and waste! Econoblast is uniformly sized for repeatable finishes and high visibility. Econoblast^TM is an Eco-Friendly synthetic aluminum oxide abrasive grain, produced by recycling vitrified bonded grinding wheels, otherwise destined for landfills. This abrasive has a proven 80+ year history as a seamless substitute, for many applications using virgin aluminum oxide.

Rule of Thumb 1 Horse Power (HP) compressor pump delivers about 4 CFM @ 100 psi

 

Air volume (CFM) and HP required to maintain specific pressure (psi) at nozzle while blasting @ 80°F, and Abrasive consumption (lbs./hour). Values vary with temperature and metering valve setting.

                    CFM - Cubic Feet per Minute (ft³/minute) Volume of Compressed Air

                    PSI - Pounds per Square Inch (lbs/in²) Air Pressure

** Do not copy without permission.

** Values are for abrasive with density of sand (100 lbs. / ft³)

** Values vary with temperature and metering valve setting.

 

·       On average: 1 Horse Power (HP) compressor pump delivers about 4 CFM @ 100 psi.

·       As nozzle bore increases, air pressure decreases exponentially (see write ups below).

·       Blast hose ID from blast pot to nozzle should be at least 3 times larger than nozzle bore.

·       Plumbing from compressor to blast pot should be at least 4 times the ID of nozzle bore, and as short as possible.

·       To check nozzle bore size, remove from holder and insert drill bits until you cannot see any light around drill bit

·       Nozzle entry throat must be same as blast hose ID to prevent excessive turbulence, and media waste.
