Great Lakes Minerals LLC (GLM), an American owned company, is a producer of refined/sized Aluminum Oxide blast media and other alumina based industrial mineral products used as raw materials in the refractory and abrasive industries. GLM has the capability to crush, size, package and warehouse Brown Fused Aluminum Oxide blast media 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 blast media in the industry. All production processes are controlled via a state-of-the-art PLC system and every pallet of finished product is bar coded 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 blast media 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 blast media applications.
Aluminum Oxide blast media is used in the abrasive blasting process. The media is accelerated through a blasting nozzle by means of compressed air. Blasting can be applied to smaller parts within blast cabinets, or applied to larger components, such as airplane parts, within blast rooms. The two basic types of abrasives are cutting and non-cutting abrasive. The most used cutting abrasive type is aluminum oxide due to its great recycling rates and its ability to open surfaces and allow for the best possible adhesion of coatings after the surface has been prepared. Choosing the correct mesh size to use is important in order to obtain the desired surface results. Aluminum Oxide blast media is one of 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 blast media is it 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.
