Container Transfer Systems

An example of a container transfer system is used in the disposal of the waste. The required transport tasks are handled by means of roll-off containers over driven roller conveyors and transverse transfer tracks. In order for the production process to run smoothly, an empty replacement container is located on the transfer device and would automatically be exchanged for the full container if required – thus, only a small downtime.

Fortunately, even with space problems, the transfer system is suitable for both closed and open top containers. In addition, the filling position can be provided with a weighing device, which will ensure that the containers are not overcrowded.

Reciprocating / Wide Belt Conveyors

The reciprocating conveyor adapts to the speed of the wide belt material conveyor and returns the defined amount of material in accordance with the desired layer height during the return movement of the carriage. During the extension movement no material is relinquished, as the belt speed of the reciprocating conveyor = extension speed. This procedure is recommended to ensure a consistent feed.


  • Wide Belt Throughput up to 1,300 t/h
  • Belt width up to 5,500 mm
  • Reciprocating Throughput up to 1,300 t/h

Bottom Ash Discharger

IEM Bottom Ash Dischargers are designed for slag residues which fall into the Bottom Ash Discharger at the end of the grate. These residues are cooled down with the help of a water bath. The slag chute is immersed in the water bath of the Bottom Ash Discharger to achieve an air seal to the furnace. The grate through fall that accumulates under the combustion grate is collected by hoppers and fed to the Bottom Ash Discharger via chutes. Here, too, air sealing is achieved by immersion chutes. The Bottom Ash Discharger, including the inlet and discharge cross-section, is designed to ensure trouble-free discharge of coarse slag and metal particles.


  • Specifications: 0,3 – 6 m/min
  • Capacity: up to 100 t/h

IEM MEC Wonderbed


IEM Wonderbed-Filter is a new process technology for catalytic mercury oxidation.
It is recommended, to install the filter behind the dust filter, in order to avoid unnecessary blockages of the continuously circulating catalysator bed. Due to the narrow bed geometry, it can be directly integrated in the outlet zone of already existing electrostatic precipitators (retrofit option). A mobile demonstration plant can show you the suitability to your local process conditions. The filter geometry can be flexibly adapted by arranging several filter lines in parallel.


The IEM-Wonderbed is an EU research project, funded by: Federal Ministry for Economic Affairs and Energy based on a resolution of the German Bundestag.


Achievable mercury oxidation rates: up to >95 % possible
Exhaust gas volume flows: 2,000 – 2,000,000 m³/h
Pressure drop: 1-6 mbar

Lowering Rails

In rotating sinter coolers, sintered material is moved on a dolly in a closed circle. In continuous operation, the cars are driven over the lowering rails at the end of the cooling section and emptied. The highest accuracy and durability are required for this application. The complex geometries of the rails are produced in a multi-stage forming process.

Swing Chutes

For uniform filling of containers and other storage units, IEM swing chutes are available. Each IEM swing chute can be adapted to local conditions and operated manually, electrically, pneumatically or hydraulically.
