Variable frequency drive control for easy adjustments of deck eccentric speed
Gauges for side tilt, feed rate, airflow, and deck eccentric speed
How do Oliver Manufacturing destoners work?
Our seed destoner machines can separate and remove stones, glass, metals, and other small amounts of unwanted materials using a fluidized bed of air and a vibrating deck that has been tilted – the same principles that apply to gravity separation. Products get fed into the deck and are then fluidized by bursts of pressured air that is blown up from underneath the bed. Lighter particles are blown up higher than heavier particles, and the downward tilt and vibrating motion of the deck allow them to flow to the bottom of the deck. Heavier particles – the stones, glass, metal, and other contaminants – are moved up.
Airflow is the separating medium in the stratification process. With the fans off, particles rest together on the screen deck. When properly regulated air is introduced, heavier particles settle against the deck while lighter particles rise. Excess airflow can over-lift and blend the material, reducing separation accuracy.
