Hilgefort manufactures the largest rotary kiln cylinder in the company’s history

17. February 2017
17. February 2017

Hilgefort already has an impressive international reputation for constructing rotary kilns. The company focussed on the particular challenges of such plants early on and has now manufactured and delivered countless rotary kilns around the world.

Manufacturing precision, proven experience in project management and transport, as well as the company’s outstanding qualifications (see Quality certificates) are all the best prerequisites of an increasing number of superlatives for requests and implemented projects.

Hilgefort GmbH is now producing a special-steel rotary kiln which will be used to manufacture fertilisers. The tripartite special-steel cylinder was the largest ever to be made in the company’s history thus far.

From the design through to production using “difficult” materials, the successfully completed project posed a number of challenges:

The outer shell is composed of a stainless chrome-nickel steel with wall thicknesses of up to 45 mm. The cylinder is separated into three lengths by means of flanged joints.

The baffles consist of 288 pieces of scoop plate in total, which in turn are screwed on to 576 supports (triangular brackets), both also made from stainless steel.

The races with a unit weight of 33 tons were then mounted and aligned on the race frames, which were pre-welded using the TIP/TIG process, to within two-tenths of a millimeter.

Shipping the components alone required the assistance of four additional mobile cranes in the factory building.
