Destoner
Description
Destoners have the same basic function as the densimetric table, with the only difference being that the stone separator has two fractions (light and heavy) and the densimetric table 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 screens. The heavier material, such as stones, coarse sand, glass, metal, etc., travels up the inclined vibrating deck.
New Horizon destoners are placed in different configurations of grain processing systems, before and after cleaning machines and gravity tables.
