Spiroflow is an innovative company, always on the forefront of technological developments to meet the continuously changing needs of our customers. The company provides complete bulk material handling solutions, end-of-line packaging, plant wide integration and much more. Here is a small sampling of our bulk material handling systems.
This custom application is a complete material handling system to mix bread crumbs and seasonings for chicken nuggets. The bulk bag discharger, fitted with a flexible screw conveyor, feeds premixed seasonings to a surge hopper. The surge hopper then feeds the seasonings to a loss-in-weight feeder that delivers the seasonings to a horizontal flexible screw conveyor.
A large hopper, filled from above, delivers bread crumbs to a loss-in-weight feeder that feeds another horizontal, slightly larger flexible screw conveyor. The smaller flexible screw conveyor delivers seasonings into the larger flexible screw conveyor creating an in-line continuous mixer. The mixed ingredients are conveyed to a hopper where an aero mechanical conveyor elevates the mixture vertically to a fourth flexible screw conveyor (not shown). This flexible screw conveyor delivers the mixture to a bulk bag filler or a packaging machine.
Spiroflow engineers designed this loss-in-weight chemical dosing system when approached by a leading manufacturer of batteries for military and medical applications.
The system mixes a proprietary recipe of carbon black, graphite, and two brands of EMD. Two bulk bag dischargers dispense EMD to a hopper. Two bag dump stations fitted with glove boxes, bag compactors, and flexible screw conveyors deliver carbon black and graphite to the same hopper. The hopper delivers the ingredients to a blender for mixing.
The mixture is then transported by an aero mechanical conveyor to a second mixer to confirm the loss-in-weight batch size. A horizontal flexible screw conveyor delivers the dry ingredients to another mixer where liquids are added.
This custom batching system was designed for a manufacturer of lithium ion batteries.
A proprietary recipe of graphite, carbon black, THV binder, and lithium ion phosphate is conveyed from three bag dump stations via three flexible screw conveyors to one of two hoppers. The hoppers feed two mixers. One bag dump station, which handles carbon black, is fitted with a glove box and a bag compactor to minimize dust.
An additional bag dump station, also fitted with a glove box, bag compactor, and flexible screw conveyor, feeds one of two mixers. The mixers combine the dry material with acetone to create a slurry required for the manufacturing process.
Three bulk bag fillers are needed for this custom PVC flour dust application for a large carpet manufacturer.
A filling source above, fitted with a rotary air lock, diverter valve, and slide gate, delivers PVC flour dust to a dual, gain-in-weight bulk bag filling system. The dual bagging station is designed for optimal bagging rates and operator productivity. While one bulk bag is being filled, an operator can remove the adjacent filled bulk bag and install a new empty bulk bag.
A third bulk bag filler is used to fill PVC flour dust collected from a plant wide dust collection system. The hopper, fitted with a flexible screw conveyor, is filled from an existing outdoor source not shown.
