What do our Glass Pulverizers do?


The Andela Glass Pulverizer¬† is an inexpensive machine that turns large volumes of waste glass into “sand” and “gravel” with no sharp edges. Feed in mixed, broken, unsorted glass, and take out round-edged aggregate. The patented Andela flexible impactors will selectively reduce the glass into 3/8″ aggregate but leave metal, plastics, and most paper in a larger form. Metal, plastic, and most paper is removed without hand sorting. Capacities are available from a small, hand fed model, up to 20 tons per hour. The Andela Pulverizer may be purchased alone for size reduction of uniform frangible material. The Andela Pulverizer may be usedin other non-glass applications for size reduction and material liberation.

Output Sized Glass

Our system also produces a distinctly different product: a rounded glass particle, 3/8″ in size or finer. If material other than glass (plastic, metal caps, or covers) goes through the pulverizer, these materials will keep their larger form and thus be easily separated from the glass-sand with the trommel separator. One or two screen sizes can be used with the trommel to produce one aggregate mix (3/8″ minus) or two different sized aggregates (1/8″ minus and 1/8″-3/8″).


Each system usually consists of a metering surge hopper, glass pulverizer, two conveyors, and a trommel separator. Each system is designed to the customers’ needs and specifications. Central to the system is the patented pulverizer. It uses a flexible impact system that pulverizes glass into usable aggregate the consistency of fine sand to gravel. The flexible impact system eliminates the grinding process typical of other machines. (reduces wear and maintenance) and produces a distinctly different aggregate, which is safe and easy to handle.
