Where machines are brought to life

Assembly in the Rundhalle (“Round Hall”)

"One must have the future in one’s mind and the past in the files."

> Charles Talleyrand, french statesman, 1754-1838

The "Rundhalle" is not just Binder+Co’s production centre but also a highlight of industrial architecture:
  • Built in 1960
  • 50 m diameter
  • 15 m high
  • Crane carrying capacity up to 10 t
  • Approximately 100 halls of this shape built worldwide following Binder+Co’s design
The roof, a conical shell suspended roof, is made from only 6 mm thick sheet steel and attached by means of membrane stress. The roof’s load is dissipated laterally through a concrete ring on the substructure which permits it to be much more slender in design. The "Rundhalle’s" major advantage was the savings made in cost and weight for the substructure; the disadvantage, mainly for production, is its round shape.

Nowadays, mechanical production, assembly and trial runs of the machines, particularly BIVITEC and DRYON, take place in the Rundhalle.

BIVITEC is an example of the success story created by Binder+Co’s innovative strength and expertise. The screening machine was developed in the 80s to screen damp coal. Screening works poorly on conventional machines because the screen openings become blocked.

As a result, Binder+Co developed a special screening machine with dynamically excited screen panels. The problematic screening material is thrown out of the screen openings at high speed to enable efficient screening. BIVITEC was the crucial development which led to Binder+Co becoming the global market leader in the separation of difficult-to-screen materials.

Facts about BIVITEC:
  • Over 1400 BIVITEC screening machines already sold
  • More than 420 million tons of bulk materials are processed with BIVITEC worldwide each year
  • Areas of application: from construction raw materials, coal and ores to compost and shredded products
  • It takes between 8 and 11 weeks to produce a BIVITEC screening machine


DRYON is the particularly gentle and efficient fluidized-bed dryer developed by Binder+Co. The dryer’s vibration and the hot air flow create a fluidized bed.

This fluidized bed ensures that the material, such as sand, salt and plastic granules, is dried gently and carefully. DRYON can also be equipped with a cooling zone to cool the material down again.

Facts about DRYON:

  • More than 400 DRYON dryers and coolers sold
  • DRYON made of stainless steel for the foodstuff and chemical industries
  • Areas of application: Construction raw materials, foodstuffs and animal feeds, coal, plastics, salts, chemical products, recycling materials
  • It takes between 12 and 15 weeks to produce a DRYON
