Great Lakes Minerals LLC (GLM), an American owned company, is a producer of refined/sized Aluminum Oxide abrasives and other alumina based industrial mineral products used as raw materials in the automotive, aviation and manufacturing industries. GLM has the capability to crush, size, package and warehouse Brown Fused Aluminum Oxide and other industrial minerals.
Our state-of-the-art facility is centrally located in Wurtland, Kentucky, strategically positioned on the Ohio River and is one of the most efficient processors of Aluminum Oxide abrasives in the industry. All production processes are controlled via a state-of-the-art PLC system and every pallet of finished product is barcoded upon packaging which provides permanent QC traceability. The GLM facility also uses some of the most advanced dust collection technology available, resulting in much greater visibility within blast cabinets or blast rooms. Our difference in quality is immediately apparent to clients when compared to competitor products. Upon shipment, product certifications are automatically emailed to customers. GLM’s core management team are some of the most qualified and experienced professionals in the industry, most of which have been in place since inception over 20 years ago.
We produce abrasive grains specifically for Aluminum Oxide Abrasive applications – in sufficient quantities for the full range of grit sizes (6 – 240). Our fused aluminum oxide abrasive grains are made for maximum toughness and hardness to deliver superior performance in your Aluminum Oxide Abrasive applications.
Aluminum oxide abrasives are the best abrasives available in terms of cleaning potential, low dusting properties and reusability. It is an extremely aggressive media and, due to its’ composition of 95% pure aluminum oxide, it will not promote rust or ferric contamination on the surfaces it is being applied to. It is commonly used in blast cabinets, blast rooms and any production environment where spent abrasive can be reclaimed. The advantage of Aluminum Oxide abrasives are that they can be reused up to 7 times for most applications, unlike other blasting media options, such as garnet or coal slag which generally have a one or two time use.
There are different types of aluminum oxide abrasives, but the most used is brown fused aluminum oxide. On the Mohs mineral hardness scale Aluminum Oxide has a hardness of 9.0, which is harder than most other commonly used abrasive blasting medias used. This is why aluminum oxide is considered a cutting abrasive as opposed to a non-cutting abrasive which would have a much lower harness. Blasting abrasives with favorable recycling qualities, such as Brown Fused Aluminum Oxide abrasives, are recommended to be applied within blast rooms or blast cabinets as opposed to the use of portable blasting equipment, as the latter doesn’t allow for recycling.
