2. Silo Logic Silo-Logic Ltd are able to offer a Turnkey Solution to all your powder handling applications. We are able to offer solutions to your materials handling, conveying and dust extraction problems. By using our vast experience of screw conveyors, industrial vibrator motors, dust filters, FIBC bag unloaders, 25kg bag emptying machines, loading bellows, silo safety systems, rotary valves, slide valves, butterfly valves and feeder systems, to name but a few, we can offer the solution to your question.

3. Dust Filtration and Dust Venting Dust Collectors have been specifically developed for many different industrial plants, including animal feed, pharmaceutical, food,building materials and water to name but a few. They are equipped with a round stainless steel body with large and no-dust deposit access door for filter element removal. The casing contains vertically mounted round bag-type filter elements with antistatic filter media. To keep the filter media clean an air jet cleaning system is integrated in the top cover.

4. Our round dust collectors are available in 4 different diameters:The casing is manufactured from 304 SS in the standard version, optionally 316L certified EN 10204/3 3.1.All parts in contact with food-grade has been certified.Configurations:• Integrated suction fan• Flanged connection for centralized suction system• Silo venting version• Positive or negative pressure conveying systems• ATEX zone 22 and Zone 21

10. Silo Over Pressure and Over Filling Safety System  The powder transfer process The majority of tankers delivering to sites are non-tipping, belly tankers on-board compressors both pressurise the air in the tanker up to 2 bar and also provide air to fluidise and transport the powder by dense phase pneumatic conveying into the silo. The setting of the various air control valves is the responsibility of the tanker driver and this becomes very critical as each tanker compartment empties of powder. As soon as there is minimal powder in the silo feed pipe, there is in effect, an open connection between the tanker, at 30 psi, and the silo, at atmospheric pressure. In this situation, the air speed in the feed line can suddenly escalate. An experienced tanker driver will try to regulate the airflow as the last of the powder empties from the tanker but, if the driver has not started to reduce the tanker pressure before the end of the powder discharge, then over-pressurisation of the silo can occur within seconds of the feed pipe being empty.

11. Silo System Components Control panel IP65, fitted with door interlocked isolatorPressure relief valve - the pressure relief valve (VCP) will to respond to silo over-pressurisation exceeding 500mm water gauge. When activated the fill pipe shut-off valve will close after 5 secondsHigh level alarm with rotation sensor, paddle type, when activated the fill pipe shut-off valve will close after 10 seconds (adjustable), if rotation stops a warning will be displayed on control panel.Ultimate high level alarm (optional), paddle type, when activated the fill pipe shut-off valve will close immediately.

12. Over pressurisation gauge, transducer displaying actual silo pressure at the tanker filling point, when 1st set point is activated alarm sounds (300mm/water gauge), when 2nd set point is activated alarm sounds and close the shut off valve after 5 seconds (450mm/water gauge)Silo filling pipe automatic shut-off valve, butterfly valve (normally closed), option for pinch valve (normally open), option for pinch valve (normally closed)Filter pressure gauge, indicates the presents of compressed air at the filter (if applicable)Audible alarm, mounted on control panelVisual alarm, flashing beacon mounted on control panelSilo fill pipe connection, mounted on the silo fill pipe with micro switchWe are also able to supply an ATEX Food Compliant Silo Safety System.

13. Loading Bellows Loading Bellows are used for efficient, dust-controlled loading of dry, dusty bulk solids into tankers. The spouts are provided with inner tapered cones to contain the flow of material and an outer double bellows to provide for dust removal. At the lower end of the Loading Bellows, a SINT engineering polymer-coated cone with special sealing properties is provided for connection to the tanker.

14. Operating Principle First the Loading Bellows is lowered from stand-by position towards the inlet spout of the tanker. As soon as the bellows outlet cone settles on the inlet spout of the tanker, the slack cable switch mounted outside the transmission box stops lowering of the bellows. The limit switch inside the transmission box stops both full extension and contraction of the bellows. Material loading is started by opening the silo outlet valve.

15. During filling of the tanker, the polymer coating of the outlet cone acts as a perfect dust seal. At the same time the filter fan continuously sucks dust through the external bellows into the integrated filter cartridges in the upper section of the unit exhausting excess air. A slack cable switch activates further extension of the bellows as the tanker lowers under the increasing material weight. A level monitoring device installed in the centre of the outlet cone signals maximum material level in the tanker compartment and orders immediate closing of the silo outlet valve. Contraction of the bellows back to the stand-by position, starts after a delay of approximately ten seconds, in order to allow the filter to evacuate the remaining dust. Once the bellows is fully contracted, the cable limit switch inside the transmission box stops operation. The preset after shut-down cleaning cycle now provides for additional pulse-jet cleaning of the filter cartridges for another ten minutes.

16. Advantages Built-in dust filter reducing dust emission during loading operationFlexible chute in Neoprene covered by Hypalon® makes the bellows weather-proof, highly abrasion and temperature-resistant and durableReverse cone with inside level control indicates when tanker is full, gradually raises loading bellows improving material distribution inside the tankerTwo lifting cables outside the material flow raise and lower the loading bellows without any cable wear due to material friction and obstruction to material flow
