We supplied a Spiroflow Aero Mechanical Conveyor, which does the job admirably.
Installed at Excelso Coffee of Norcross, Georgia, in 1994, this Aero Mechanical Conveyor is used to convey flavored coffee from a ribbon blender to a storage hopper above a packing machine. The conveyor, operating intermittently eight hours /day, five days /week, ran for 14 years before requiring a replacement cable and disc assembly.
Keeling & Walker is the world’s largest producer of Tin Oxide which is abrasive and difficult to handle. When replacing a troublesome bucket elevator, they sought a conveyor man enough for the job. Trials at Spiroflow indicated that an Aero Mechanical Conveyor was ideal; verified since by the performance of the unit installed.
A manufacturer of construction industry products required a reliable replacement for an existing materials delivery system. Additives arrive in bulk bags, up to 1.8 tons, or 50 lb bags. Our solution included two Bulk Bag Dischargers and two Aero Mechanical Conveyors. One of the Dischargers has an integral Bag Dump Station.
A manufacturer of cement products needed to discharge 5 components from 3,000 bulk bags for delivery to either of two mixers. Spiroflow supplied five (5) loss-in-weight bulk bag unloaders with metering feeders to transfer constituents into a horizontal aero mechanical conveyor. This feeds a second vertical aero mechanical conveyor which lifts materials to the ‘wet’ or ‘dry’ mixer.
A Pork Pie manufacturer looked to Spiroflow to improve the loading of gelatin granules into two mixers. The Aero Mechanical Conveyor supplied has an integral feed hopper. The conveyor, feed hopper and control panel are all mounted on a mobile frame for movement between mixers and away from both for periodic washing.
Faced with growing demand, Everbuild, manufacturer of building sealants, adhesives & fillers, installed a new mixer alongside an existing machine. They then needed to load bulk materials & minor additives into both mixers. Spiroflow supplied a loss-in-weight bulk bag unloader to dispense accurate quantities. Minor additives, are loaded through an adjacent bag dump station.
Nynas’ original asphalt plant needed upgrading. The joints and bends of the pneumatic conveying system were wearing out. It also needed a sizeable filtration system which had environmental implications. Spiroflow Aero Mechanical Conveyors transferring materials from Bulk Bag Dischargers have proven to be an effective replacement and eliminated the environmental issues.
Robert McBride Ltd. manufactures private label household & personal care products. To improve efficiency & eliminate dust in their plant, they needed to eliminate manually loading 50 lb (25 kg) bags of chemicals used to manufacture their descaling gel. Spiroflow provided a bag dump station with a dust hood, a short flexible screw conveyor & an aero mechanical conveyor to do the job. The equipment meets all their needs including their required 6,600 lb/hr (2,994 kg/hr) material conveying rates.
This Ghana based producer of bitters needed to increase production by a factor of ten. They turned to Spiroflow who recommended an 'round the corner' Aero Mechanical Conveyor and a bag dump station. The AMC handles the significantly increased need to convey sugar both vertically and horizontally without loss of efficiency.
Unifi, developer and producer of REPREVE® recycled fiber, creates plastic flake from the millions of plastic water bottles used every day. Spiroflow helped them develop a line to fill & recirculate plastic flake into large mixing silos & also convey flake onto the next step in their manufacturing process. This system included a box dumper, two (2) bulk bag unloaders, five (5) flexible screw conveyors, four (4) aero mechanical conveyors, a hopper & a comprehensive custom control panel.
Although the materials listed are traditionally handled manually, in a modern pulp and paper plant they are normally handled in Bulk Bags (FIBCs). Due to the large quantities used, bulk bags are replacing 50 lb. bags. Spiroflow's material handling systems help pulp and paper companies reduce dust, reduce cost & increase operator safety.
Spiroflow has developed a bulk bag discharge system which provides a proven solution for handling titanium dioxide and other poor flowing, cohesive products, which tend to bridge in hoppers, cause smearing of conveyor tubes and generally create production nightmares for process engineers.
Aero mechanical and center-less screw conveyors are widely used for filling road tankers and can be mounted on mobile frames for ease of use. Spiroflow offers bulk bag (FIBC) or rigid bin discharge stations as an integral part of tanker and rail car loading systems. A high level probe in the discharge spout insures automatic conveyor shut-off once the tanker section is filled.
When conveying Dry Ice Expanded Tobacco (DIET) the main requirement is to maintain very low levels of product degradation. Tobacco companies also need a reliable and cost effective solution. Belt conveyors with multiple drop points can significantly increase degradation. With the correct conveying system in place, annual cost savings for reduced product degradation can amount to thousands of dollars.
Spiroflow worked with Access Security Products Ltd. to resolve a powder handling problem with a proprietary cement mixture used in their manufacturing process. The material is a fine powder, which arrives by container quite compacted, has very poor flow characteristics bridges easily, is very abrasive & readily absorbs moisture. Spiroflow installed a bulk bag unloader fitted with dual flexible screw conveyors. The flex screws deliver the cement powder to two (2) aero mechanical conveyors that fill an outdoor silo about 40 ft (12m) outside of the building.
North Carolina based Colony Gums provides the finest quality gums & stabilizers to the food, pharmaceutical & chemical industries. They turned to Spiroflow to increase their conveying capabilities. They now have two side by side powder handling systems that deliver a conveying rate of 20,000 lb/hr (9 tph), with improved productivity, additional safety features, a cleaner environment & reduced product waste.
For the ultimate in peace of mind, Spiroflow's AMC DART uses a load-cell system that checks that the tension is at the force determined for the diameter and length of the conveyor. It maintains it at that level by constantly adjusting the air supply to accommodate changing conditions. This is especially desirable where the product or the ambient air is subject to significant changes in temperature.
