Identifying Powder Handling Applications Solution

1. Identifying Powder Handling Applications Solution

2. Screw Conveyors & Feeders Screw Conveyors have been made to offer a variety of solutions for conveying or feeding of powdery or granular materials. They are suitable for applications in which any contamination of the material handled has to be strictly avoided and where absolute cleanliness and perfect resistance to corrosion are required. In particular, Stainless Steel Tubular Screw Conveyors are used in environmental technology, in flour and animal feed milling, in food processing and packaging, in plastics and chemicals, as well as in the pharmaceutical industry.

3. Technical Features For Food & Pharmaceutical Screws The spiral of the screw is welded on both sides and the weld structure is provided with a connecting radius of 3mm.• Both ends of the screw conveyors should be such as to minimize the presence of areas of product residue.• Seals and gaskets are compatible with food requirements.• Screw conveyor couplings are outside the areas in which the product is in contact with them to avoid residual risk.• It Is preferable to install a direct drive transmission instead of belt or chain transmission to avoid risk of

5. Rotary Valves Description  Drop-Through Rotary Valves with square inlet or with a circular inlet consist of a tubular cast iron or stainless steel casing, a horizontally mounted rotor with a certain number of V-shaped cross section compartments, a drive unit and a casing cover opposite the drive end. Function Rotary Valves have been developed for maximum versatility in application. They are suitable for controlled discharging and feeding of powdery or granular materials from silos, hoppers, pneumatic conveying systems, bag filter houses, or cyclones.

8. Butterfly Valves Butterfly Valves are used in all types of powder and granular material processing plants where interception of gravity/pneumatically fed dry materials is required. Butterfly valves can be fitted beneath hoppers, bins, silos, screw or other conveyors, or to intercept pneumatic conveying ducts. Sizes available: from Ø 100 mm to 500mmBody: aluminium alloyDisc Seal: Elastomer (NBR)Disc: SINT®, St. Steel or Cast IronFDA approved on certain models

9. Slide Valves Characteristics Low Profile VIB Slides Valves are used where flow of a dry powder or granular material caused by gravity or conveying has to be intercepted. Low Profile VIB Slide Valves may be fitted beneath hopper, bin or silo outlets, on inlet and outlet spouts of mechanical conveyors, as well as above the inlet of telescopic loading spouts. Sizes available: □150 mm (6”) ~ 400mm (16”)Body: aluminium alloyInternal liner: SINT ® polymerBlade: Mild or 304St. SteelRoller bearing: standard or stainless steelFDA approved on certain models

10. Bin Activators The Bin Activator is the ultimate machine, specifically designed to meet the requirements of the food industry. With its hygienic finishing design, the EC 1935/2004-certified BAF is suitable for a variety of applications in food processing. It excels in applications with a requirement for minimum residual of material and zero contamination. Throughput = 5 ~ 320 m3/h (3 ~ 190 cfm)Range: Ø 400 mm (16 in) ~ 3,000 mm (10 ft)Outlet Range: Ø 114 mm (4 in) ~ 406 mm (1.3 ft)Material: 304L / 316L stainless steelHygienic Design

11. 1 Tonne FIBC Bag Unloader & Fillers The FIBC Unloader is a modular system for discharging Flexible Intermediate Bulk Containers (Big Bags). The four loops of the FIBC are attached to the hooks of the detached cross bar that has previously been laid on top of the FIBC. The cross bar with the attached FIBC is then picked up by a forklift truck and introduced into the frame of the SBB Discharger. Once the FIBC has settled on the rubber seal of the discharge hopper the outlet closing rope of the FIBC can be pulled open through the inspection hatch of the discharge hopper.

12. FIBC Filling Stations consist of a steel frame and a bag filling unit including an inflatable seal that impedes dust leakage during the filling process. FIBC Filling Stations enable efficient filling of bulk bags. The empty FIBC is attached to the four tensioners in the upper corners of the frame. Then the bag inlet is pulled over the loading spout of the station. The filling procedure starts as soon as the seal around the bag inlet is inflated. Once the FIBC is filled up it will be lifted by a forklift truck and transferred to its further destination once the FIBC has been removed from the steel frame.

13. Lump Breaker The Lump Breaker consists of a square cross section casing with upper and lower flange, two horizontal rotating shafts equipped with chopping knives, a grid to hold back lumps, four end bearing assemblies with integrated adjustable shaft sealing unit, an appropriately sized drive unit complete with power transmission. The DLP Lump Breaker is the ideal device for breaking up material lumps which have formed during material handling or processing but are soft enough to be broken up (friable). The quick rotation of the special chopping knives through a fixed grid carries out the job. The presence of two rotor shafts results in high throughput rates.

14. 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.

15. Main Specifications For Dust Collectors For Food & Pharmaceutical Applications Production Process Traceability according to EC 1935/2004• Food-grade raw materials, approved and certified• Hygienic design• Zero DUST deposit – NO DEAD SPACES• Captive locking system• Sand blasting surface finishing• Stainless steel body AISI304L and 316L• Suitable for explosive environments, ATEX zone 22 / 21 external and 20 internal

16. Silo Over Pressure and Over Filling Safety System  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.
