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 Custom Processing Services offers the Alpine AFG fluidized bed jet mill system. For super fine glass applications, with a cut point (top size) of 5 to 50 microns the jet mill will typically be wear protected with an aluminum oxide classifier wheel and outlet. This construction allows for fine grinding and durability.
Hosokawa Custom Processing Services has the experience and expertise to provide quality processing for this challenging application.
