The CONIDUR® perforated sheets from HEIN, LEHMANN are characterized by a special conical perforation that deviates from the conventional round shape and has a triangular to semi-elliptical shape. This conical opening, which is angled in the throughput direction, enables lower throughput resistance, reduces blockages and increases throughput, making it indispensable for a wide range of industrial applications.
These fine-perforated and slotted perforated sheets can be individually adapted to specific customer requirements and are available in a variety of designs that differ in terms of material quality, initial sheet thickness, perforation and surface finish.
Through work hardening and post-treatment of the surface, they exhibit increased wear resistance, which increases their durability and efficiency in industrial processes.
The areas of application for CONIDUR® perforated plates are diverse and extend across the chemical industry, the food industry, the pharmaceutical industry and process engineering. They play an important role in the inflow plates of fluidized bed and fluidized bed reactors, in centrifuges, mills, cheese dairies and starch centrifuges. They ensure uniform air distribution in the fluidized bed, blockage-free openings in the centrifuge and increased comminution performance in milling technology, which ultimately improves the quality of your industrial processes.
