The GK DE-STONER® Air Classifier for Wood creates distinct material separations based on chosen size and density. Divide heavier products from lighter ones in a dry environment for ecological friendliness, ready-to-use product, and maximum profits. The GK DE-STONER® Air Classifier is the perfect solution for efficient, high volume stratification.

The DE-STONER® Air Classifier combines vibratory action with air streams to effectively separate high volume production rates up to 10,000 cubic feet per hour (280 cubic meters per hour). The high velocity / low-pressure streams fluidize and classify material according to difference in terminal velocity of particles. Through this process, heavy items such as glass, metals, and stones are separated from lighter wood, mulch, or pellets fraction.

Bucket Elevator

Easily elevate your material in a small footprint with TUFFMAN bucket elevators. TUFFMAN bucket elevators are ideal for conveying many bulk materials such as sand, pellets, ash, shot, or powder. These bucket elevators feature a centrifugal discharge and can handle up to 175 tons per hour standard. The material transfer buckets are made of nylon material or ductile iron, capable of handling extreme temperatures.

Lost foam casting process

The lost foam casting process begins with a polystyrene foam pattern that is manipulated to form a mold. A refractory coating (or ceramic investment) is used to cover this foam pattern. This coating helps protect the smooth foam surface from the rough sand surface. After the coating is finished drying, the foam pattern is placed in a flask and is surrounded by un-bonded sand. A vibration table is then used to compact the sand, and the mold is then ready to be poured. Molten metal is poured into the polystyrene foam pattern which gets vaporized, leaving behind the metal. Finally, in the last part of the lost foam casting process, refractory coating is removed exposing the metal part.
