About Schrage
Schrage Conveying Systems GmbH is an owner-managed family business from Friedeburg that has specialised in tubular chain conveyors and bulk material conveying systems for around 39 years. The product range includes the Classic line as a modular system in five sizes (Type 115, 135, 160, 200, 270), mobile and stationary bulk material loading, customised bulk material solutions as well as equipment for dosing, emptying, distributing and discharging such as BigBag and sack emptying stations, rotary valve feeders, loading units and flat slide gates. The systems convey bulk materials with grain sizes up to 100 mm, bulk densities up to over 5 t/m³ and throughputs up to 80 m³/h over conveying distances of up to 50 m horizontal and 30 m vertical. In the company's own technical centre, bulk material analyses, conveying trials, test runs, long-term tests and wear tests for material pairings are carried out. Manufacturing, machining, assembly and dispatch take place at the headquarters in Friedeburg; the systems are in use worldwide, including ATEX versions and an EAC declaration of conformity for the Eurasian Economic Union.

Technology & Processes
Tubular chain conveyors (modular system)
Five sizes (115–270) with 18 line guide variants LF1–LF18 for horizontal, vertical and diagonal conveying, dust-tight and gentle on the product.
ATEX versions
Tubular chain conveyors and flat slide gates as non-electrical equipment of equipment group II with ignition protection type h for explosion-hazardous areas.
Pneumatic conveying system
Alternative conveying technology for bulk material applications within the company's product range.
Bulk material handling systems
Emptying stations, rotary valve feeders, loading units, two-way diverters and flat slide gates for dosing, emptying, distributing and discharging.
Technical centre & bulk material analyses
Wear tests determine the suitable material pairing for scraper discs, conveyor chain and housing (pipes and pipe bends).
