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

EconoblastTM 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.

EconoblastTM 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. EconoblastTM 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. EconoblastTM 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.

USES:  Wheel/Stone manufacture, Pressure Blasting Cabinet/Room (surface preparation  for bonding, removing hard coating, power turbines, hardened metal, scale removal, glass/stone/ceramic etching, investment castings, light deburring, matte finish, and for high production rates), Water-Jet, Lapping, Mass Finishing, other finishing operations.

** Values are for abrasive with density of sand @ 100 lbs. per cubic foot. 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 light around bit.

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

 

See our other available abrasive media on ebay:

Aluminum Oxide, Silicon Carbide and White Aluminum Oxide in three different package sizes: 4 lbs., 25 lbs., and 50 lbs. Our 50 lbs. package is shipped in two 25-pound boxes and the others come in a single box.

We are able to size to meet any standard, and can do custom sizing to make grit sizes: 16, 20, 24, 30, 36, 46, 54, 60, 80, 100, 120, 150, 180, 220, 240, and 240F

These grit sizes conform to the American National Standards Institute (ANSI) B74.12-2001 Table 2 Allowable Limits for the Sizing of Aluminum Oxide and Silicon Carbide Abrasive Grain for Grinding Wheel Manufacture and General Polishing Purposes.

 

For every ton of Econoblast sold – 1 to 2+ tons of "Red Mud" Sludge are prevented from being generated!

 

For Your Information (FYI)

White, pink, ruby, and ceramic aluminum oxides, known as specialty aluminum oxide abrasives, are produced via the "Bayer Process". This process, also used to make aluminum metal, requires the use of caustic soda (lye), which generates a dangerous sludge byproduct, with a pH between 9 to 13, called "Red Mud". For every ton of high purity alumina produced, 1 to 2+ tons of red mud are generated. The US EPA estimates over 3,000,000,000 tons of red mud are being stored around the world, and around 120 million tons are added each year. In October 2010 one of the storage sites collapsed, releasing a 3-to-7-foot wave of this toxic waste. Ten people died, many had severe chemical burns, and the ecological effects continue to this day. (Our recycling process does not require use of any chemicals, and only requires a fraction of the energy. By using our recycled aluminum oxide, you are reducing the use of our primary resources, and the generation of toxic “Red Mud”.)
