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.
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
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.
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).
is achieved by a special manufacturing process, which also increases
the strength and wear resistant capability to provide long life
Greater open areas are available when using CONIDUR® slotted
hole screens as often required in a centrifuge screen.
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.
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.
