Permeable, Pleated Top Filter
Another innovation is Shick's pleated filter cover. The cover of the silo provides 540 sq. ft. of
surface area - more than enough to handle the dust collection requirements of a pneumatic conveying
system and a PD tanker filling operation. The pleated filter cover requires little maintenance.
Zoned Aeration Discharge
Reliable and efficient discharge of a bulk product is accomplished utilizing Shick's proprietary and
proven "zoned" aeration system. The top layer of the liner system is made of a heavy-duty polyester
belting that is sewn onto a bottom layer made of PVC coated fabric. Air passes through the top
layer providing fluidization of the bulk product. The liner has 12 zones which are individually
inflated or cycled to ensure uninterrupted flow to the discharge airlock and complete discharge
of the silo.
Interior Liner
Because most indoor silos consist of dozens of bolt-together panels, interior seams typically
require gaskets and caulking to prevent leaking. To eliminate this concern, Shick uses a flexible
liner (as part of the aeration liner system) that completely covers all interior surfaces of the bin.
The liner provides a clean, smooth surface and a moisture barrier for bulk storage.
Air Distribution Controller (ADC)
The ADC operates at the same time as the rotary valve. High volume, low pressure air is supplied through the
ADC at timed intervals. Each of the 12 zones is aerated intermittently with the zone at the center
discharge. The center zone action ensures a constant feed rate of the bulk material to
the discharge valve.
