Belt Feeders for Metering Silica Flour

Application Notes & Case Studies /

Given the small powder-like particle size of silica flour, it can be extremely dusty if it enters the atmosphere and could cause health issues if inhaled. The KWS belt feeders are totally enclosed using heavy-duty gauge steel and dust and weather tight. The enclosed design also aids in minimizing housekeeping concerns. The material flow from the storage silo must be contained to provide accurate metering of the silica sand to the finishing mills. The flow is controlled using an adjustable sliding strike-off plate fabricated from abrasion resistant steel. The strike-off plate prevents the material from free-flowing down the belt and controls the material depth on the belt. When combined with the KWS hammer style roller slide gates mounted between the storage tanks and belt feeders’ inlets, high metering accuracy is achieved.

Exterior Coatings Producer Blends Abrasives With No Shaft Seal Wear

Application Notes & Case Studies /

When blending the coatings, ingredients are added to the 100 cu ft (2.8 cu m) ribbon blender in several steps. First, liquid acrylic polymer and water are metered by a pumping system. While the blender is running, 50 lb (23 kg) bags of pigments and fillers, together with various pre-weighed chemicals, are manually dumped into the blender. Next, pre-weighed aggregates are added from self-dumping hoppers using a forklift. Typically, the blend contains about 25% liquids and 75% solids.

Complete Bagging & Packaging Line for Cold Patch Asphalt

Application Notes & Case Studies /

B Metcalf Paving has recently purchased an automated system for bagging and palletizing cold patch asphalt. The Incline Auger Packer gross weigh scale and TRP3000 Palletizer make operation simple and efficient.

With a single man operation the gross weigh scale will fill up to 3 bags per minute and with two operators the scale can fill up to 6 bags per minute, handling various bag types and sizes. Each bag is sealed, knocked down, and flattened before being sent to the TRP3000 palletizer to be picked and placed on the selected pallet stacking location.

Biaxially-Oriented Film Production

Application Notes & Case Studies /

There is a clear trend in specialty film production to multilayer film types, where more and more co-rotating twin screw extruders are utilized. This enables film manufacturers to simultaneously feed a large variety of additives directly into the extruding process, increasing flexibility and reducing production costs. This is very beneficial in the production of multi-layer high barrier films, balanced shrink films, etc.
