The ball mill will typically be constructed with Aluminum Oxide media and ball mill lining for quartz applications. The most common Hosokawa air classifier used for Quartz is the Hosokawa Alpine Stratoplex (ASP) which is used for a cut point (top size) of 20 to 200 microns. For super-fine applications, the Hosokawa Alpine Turboplex (ATP) air classifier is used, 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 and interior Aluminum Oxide tiling for fine grinding and durability. Hosokawa has the experience and expertise to set up quality systems for these challenging applications. The Hosokawa Alpine AFG Fluidized Opposed Jet Mill is the mill of choice for very high-purity applications. The particle-to-particle impact avoids equipment wear, providing a high-purity product. In the Hosokawa Alpine AFG Jet Mill, the material is fed into the milling chamber to form a bed. Opposing nozzles create high-speed air streams (up to 1000 MPH), which fluidize the powder and cause the powder to impact against each other in the center of the chamber. The flowing air eventually rises the chamber. It flows into the rotating classifier wheel, allowing the particles that meet the particle size specification to flow through while forcing the larger particles to fall back into the fluidized bed and re-ground. Various pressures, nozzle sizes, and variable speed classifier wheels provide a wide range of particle sizes that can be achieved with the AFG Jet Mill.
