Sintering plants

In sintering plants, lumpy iron ore sinter for use in blast furnaces is produced from fine-grained raw material.

These plants process ore dust, concentrates, aggregates and undersize particles that accumulate at the blast furnace when the lumpy burden components are sifted. Recyclable materials from the entire plant production chain are also incorporated. The dusty exhaust air flows that are produced during these materials management processes are filtered in what are known as secondary dedusting systems.

Using coke breeze (which is produced during the process of sifting lumps of coke at the blast furnace) as a fuel, iron ore sinter is created on the sintering belt (chain grate) after firing as part of an induced draught process. The exhaust gas that is generated in the process is fed to an exhaust gas cleaning plant.

When the sinter is discharged, it is broken up and cooled in coolers. In turn, this produces exhaust air containing dust and waste heat.

Outstanding cleaning performance combined with an excellent degree of separation

The Scheuch IMPULS filter is a high-capacity filtering separator that delivers outstanding cleaning performance combined with an excellent degree of separation. It is used for the dry separation of solid matter, primarily in the extraction of contaminants from machinery and the workplace, as a process filter in material recycling, or for conveyed material separation purposes.

The patented IMPULS cleaning system

Thanks to the specially shaped twin nozzles on the jet pipe, the pulsed free jet pulls along an envelope of clean gas from the primary compressed air as it makes its way to the injector. The two gas flows are mixed in the injector by means of pulse exchange an, at the same time, experienceing significant increase in pressure. This ensures highly efficient cleaning throughout the bag length and filter bags require cleaning less frequently.

Proven in practice for decades, the IMPULS cleaning system has become a byword for low operating costs:

  • Low compressed air consumption
  • Long service life demonstrated by filter media
  • Very little maintenance or servicing required




Radial Fan


The right plant concept for the perfect fan specification

A plant's ability to demonstrate a high level of safety and reliability is essentially dictated by its key components. The radial fan is one of the components at the heart of every extraction, dedusting, exhaust and flue gas purification, and pneumatic conveying system. It helps to meet customer requirements with a level of quality that guarantees fault-free operation and excellent performance between maintenance intervals.Drive designs:

  • Direct via engine shaft
  • Via belt
  • Via coupling up to 1,000 kW

There are also three different types of impeller:

  • Impeller for transporting clean gases
  • Impeller for transporting gases and shavings with high dust concentrations
  • Impeller for transporting fibrous material

Radial fans with direct drive up to 132 kW

Despite offering higher performance, this enhanced range incurs costs that are lower by around a third as compared to fans with a coupling drive – it also takes up less space. Even when combined with a frequency converter, it represents a less expensive alternative to fans with belt drives. The range has been designed and calculated in line with the latest findings in the field of fluid mechanics:

  • Drive power up to 132 kW
  • Volume flow rate up to 100,000 m³/h
  • Pressure increase up to 20,000 Pa
  • Conveying temperature up to 250°C
  • Impeller diameter up to 1400 mm
