CONIDUR® fine hole plates and slotted screens



	With perforated hole sizes from 20 micron CONIDUR® fine hole screens can provide great increases in milling filtration and separation throughput due to their specific hole shape particularly when compared against laser cut screens.

Conidur® fine hole plate

The ability to produce screen cylinders down to 50mm and in some cases to 20mm and combined with wedge wire provides a suitable filter medium for oil extraction, paint and chocolate manufacturing as well as use in the pharmaceutical industry.

Conidur® Slotted hole screen

With perforated hole sizes from 20 micron CONIDUR® fine hole screens can provide large increases in milling filtration and separation throughput due to their specific hole shape particularly when compared against laser cut screens.

One of the most significant features of CONIDUR® fine hole screens contributing to increased product throughput in milling, filtration and separation applications, is the triangular to hemi-ellipsoidal specific hole shape, which differs from cylindrical round holes due to its conical shape. This feature allows product to exit the aperture faster due to the limited resistance and thus reduce product binding.

In fact CONIDUR® fine hole screens used in a comparison tests in the USA on a hammer mill screen application produced a 70% greater product throughput when compared against laser cut screens.

In addition to increased product throughput CONIDUR® fine hole screens can also extend screen life due to the option of screen material thickness being up to 6 times greater than the conical hole diameter, which can be as small as 20 micron (0.02mm).

This is achieved by a special manufacturing process, which also increases the strength and wear resistant capability to provide long life screens.

Greater open areas are available when using CONIDUR® slotted hole screens as often required in a centrifuge screen.

Typical applications involve flour milling screens, filter leaves and plates, centrifuge screens, all of which can be supplied in a wide variety of materials, including – carbon and stainless steel, Titanium, Hastelloy, Inconel etc.
