Service, Support & Optional Extras

All Crown Gravity Separators are robustly constructed from mild steel with a lightweight efficient aluminium deck framework which is easily changed for different products. The deck includes a stone trap and adjustable heavy and light product outlet gates.

Our decks can be supplied in various sizes of woven mild steel as well as with linen covers for fine seeds.

Two heavy product hoppers, one light product hopper and an air inlet filter are included. The machines are available in right or left hand construction for ease of installation and to enable doubling up when required.

Crown offers a comprehensive spare parts backup service; from small serviceable items such as belts, bearings & bushes, right up to major items which are manufactured in house on a turnaround time basis.
