On Stand No: 912 at the RWM Exhibition, S+S Inspection will be showing the new Varisort Compact optical colour sorter that solves the problems of feeding granular and pellet material by replacing the conventional feed chute or conveyor with a free-fall system that increase productivity and net yield by eliminating unreliable material separation.
Using specifically matched vibratory feeders to deliver the material for sorting to a high-speed conveyor ensures homogeneous distribution across the full width of the belt. On leaving the conveyor, the material falls in a parabolic curve past the high-speed cameras that trigger fast air valves to deflect identified particles into a separate output chute with the bulk of the material falling onto the output conveyor. This system eliminates problems associated with feed chutes and variable friction and minimises the proportion of good material lost during separation.
Compared with chute/conveyor systems, the Varisort Compact free fall system is very compact and easy to clean. The high-resolution CCD cameras and sophisticated image processing software provide optimal detection and analysis at very high throughput rates of up to half a million particles per second. Depending on the application, a very large number of air-valves capable of switching at up to 500 cycles per second can be fitted to ensure precise and reliable material separation even at high reject rates.
