Large grain concave for wide body (67” wide) Lexion machines. Centre inserts have a ‘V’ to assist in material flow. The front half of each concave consists of a channel structure weldment that will provide strength and durability. Each concave accepts bolts in “boxes” that are reversible (excluding the centre insert) and replaceable. All concave frames are heavy-duty with more robust bars and thicker ‘ribs’ to maintain structural integrity.
