Glass / Recycled Glass Powder
It takes a lot of minerals, energy, and water to make glass from raw materials. Fortunately, glass can be recycled endlessly without any loss in purity or quality. With the abundance of recycled glass, the demand for finely ground glass powder is rapidly increasing in the construction industry.
Recycled glass can be turned into countertops, flooring, tile landscaping stones and bricks. For added strength and lower costs, glass powder is being used in cement as an alternative to Portland cement or fly ash. It can also be used to make light-weight aggregates/bricks with chemical resistant properties.
Glass is one of the more difficult materials to process as it has a high hardness (Mohs hardness of ~5.5 to 7) and sharp edges upon fracture. Durable, field-proven, equipment and techniques are required for successful glass grinding, especially for ultra-fine milling requirements.
For high quality, ultra-fine, glass powder production, Hosokawa Micron Powder Systems offers the Alpine Super-Orion Ball Mill in circuit with an Air Classifier. For glass applications, the ball mill will typically be constructed with hardened, high chrome, steel media and ball mill lining. A second option would be Aluminum Oxide media and lining.
The most common Hosokawa Air Classifier used for glass is the Hosokawa Alpine Stratoplex (ASP) which is used for a cut point (top size) of 20 to 200 microns. The Hosokawa Alpine Turboplex (ATP) air classifier is used for super fine applications with a cut point (top size) of 5 to 50 microns, with single and multi-wheel options. Both classifiers are made with Aluminum Oxide classifier wheels, with an interior Aluminum Oxide tiling. This allows for fine grinding and durability.
