Abrasion Resistant Rotary Mixer

Kopp Glass, a world leading producer of precision molded borosilicate glass, relies on a rotary batch mixer from Munson Machinery to blend more than 300 glass compositions in unlimited colors. Kopp produces its glass in small batches, typically in the range of 100 to 1,000 pieces. The powdered ingredients are mixed, melted in a pot furnace, then molded by skilled craftsmen. The mixer is a vital part of Kopp's operation. A batch may contain anywhere from five to 15 ingredients that must be mixed thoroughly in order to guarantee product quality. Sand accounts for 60-75% of a formulation and the rest of the ingredients include borax, metal oxides and various other minerals.

Rotary Batch Mixer Blends Wood Powders for Plywood Adhesives

For pure blending in high volume, the Willamette Valley Company replaced a Ribbon Blender that agitates material, with a Rotary Batch Mixer that tumbles it. "Our glue customers are very particular when it comes to their ingredients, so consistent quality is important. The ribbon blender did not mix materials thoroughly enough," says Don Coleman, plant manager. "The material, which customers mix in vats in their own formulations, could clog filters and shut down lines if not properly blended."

The Munson Machinery Model 700-TH-140-MS at Willamette Valley blends uniformly in about four minutes, with throughput of 6000 lb (2721 kg) per batch. Capacity of the previous ribbon blender was one third of that amount, and was being outpaced by demand.
