Positive-pressure pneumatic conveying system

Safe and re­li­able trans­port of ma­te­r­ial Pneu­matic sys­tems are ex­tremely safe and re­li­able and – be­cause they con­tain hardly any me­chan­i­cal or mov­ing parts – are vir­tu­ally main­te­nance-free and non-wear­ing. There are gen­er­ally two ba­sic de­signs: the low-pres­sure or low-den­sity con­vey­ing sys­tem, which uses a ra­dial fan as the com­pres­sor, and the high-pres­sure or high-den­sity con­vey­ing sys­tem, which uses a ro­tary pis­ton blower. High-pres­sure sys­tems are ideal for use with con­vey­ing quan­ti­ties of 1 to 100 t/​h, con­vey­ing sys­tems of up to 1500 m in length, and nom­i­nal widths be­tween 88 and 500 mm. HIGH-PRESSURE CONVEYOR SYSTEMS For longer conveying paths and higher quantities of material The longer the material conveying path and the higher the quantity of material that needs to be transported, the more criteria speak for the use of high-pressure conveyor systems. The key components of this design are a rotary blower that combines high levels of efficiency with low energy costs, and airlocks such as massive rotary valves (Scheuch type zss) or particularly massive cutting rotary valves (Scheuch type zsm), both in welded design. Even with large quantities of material, the injectors ensure that only a small amount of energy is expended for the drive power. Thick-walled steel pipes and bends with wear protection ensure long service lives. High-pressure systems are ideal for use with conveying quantities of 1 to 100 t/h, conveying systems of up to 1,500 m in length, and nominal widths between 88 and 500 mm.
