The basic principle of the destoner is to effectively separate heavier-than-product debris, such as glass, stones and metal from a large amount of light product.Forsberg Destoners are constructed of heavy gauge steel and driven by a unique eccentric drive which is counterbalanced for years of trouble-free operation.
The Forsberg Destoners have the same basic function as a separator with the only difference being the destoner has two fractions - light & heavy, and the gravity separator has multiple fractions.
The basic principle involves flowing dry material over an inclined, vibrating, screen covered deck. The steady air flow holds the material in stratified flotation. The lighter material stays in the upper strata as it flows down the inclined vibrating deck with screen. The heavier material, such as stones, coarse sand, glass, metal, etc., travels up the inclined vibrating deck and out.
Destoners are placed in many different locations in a cleaning system, both before and after cleaners and gravity separators. Destoning is not only used as a means of eliminating contaminants to improve the purity of the product, but is also essential to remove stones to eliminate excessive wear on all types of grinding mills, flaking machines, etc.
Air is then dispersed through the deck and product where the separation begins. The steady air flow holds the lighter product in stratification as it advances down the inclination of the vibrating deck. The heavier material such as stones, glass and metal, travel uphill and out. The product is then directed toward the discharge end of the deck where the finished product is collected and often needs no further refinement. Forsberg destoners are known for their remarkably fast and thorough separation of heavy foreign material removal. Right now they are working throughout the world on spices, chemicals, coffee, peanuts, cereals, beans, wheat, minerals, and numerous other products.
