CONIDUR® perforated sheets have a special shape of openings. In contrast with common round or oval holes, the CONIDUR® openings look rather triangular to semi-elliptical with an oblique, strongly conical perforation in the direction of the flow.
Thanks to cold hardening, the wear resistance of CONIDUR® perforated sheets is very good and can be even further improved by an additional surface treatment.
CONIDUR® perforated sheets can be used for processing dry, wet and even very wet loose material of nearly any chemical and physical nature.
Since CONIDUR® is a highly unique product, a consultation with our specialist is always necessary.
1) fine hole sheets, flattened/grinded
2) slotted hole sheets, flattened/grinded
The difference between those two types is in the shape of the openings. The fine hole sheets have rather triangular to semi-elliptical openings. The slotted hole sheets, in contrast, show oblong perforation giving a bigger open space than fine hole sheets.
