STB Engineering was founded in Stroud in 1969, pioneering the development of Dense Phase pneumatic conveying technology, silo manufacture and powder handling systems. The company established itself as the UK’s leading Bulk Materials Handling and Pneumatic Conveying Specialists. Our early Dense Phase systems found favour with the likes of the Milk Marketing Board and the Polymer industries, where the need to transport high volumes of powders over long distances with minimal degradation was paramount. In addition, this type of conveying was more hygienic and was found to require far less maintenance than mechanical conveying techniques. Many of the early systems installed are still in operation today, performing to their original specification after 30 years’ continuous service. At the time, cohesive powders had not been successfully conveyed using the Dense Phase method and in the early ‘70’s, STB became one of the first companies to market Pulse Phase conveying technology. This refinement of Dense Phase conveying made it possible to transfer cohesive products down a pipeline at low velocity by using an air knife to ‘cut’ the material into plugs. More recently, there has been a trend towards vacuum systems and this has proven especially popular in the field of plastics and PVC extrusion. Today, the STB Vacuum Line Feed System feeds more major PVC extrusion plants in the UK and Ireland than any other type of system, bearing testament to its proven performance and reliability. STB has also acquired complementary expertise in batching and weighing systems in the food, pharmaceutical, plastics, chemical and mineral industries. STB is the UK market leader in the supply of mixing plants to the polymer industry. In 2015 STB Engineering Ltd became official supply partners for Hennlich Engineering and Arcomet7 S.L. Hennlich Engineering specialise in dust control.
