A TEC Rocket Mill

A TEC Rocket Mill

The Rocket Mill is A TEC’s innovation for alternative fuel preparation which combines drying, grinding and homogenising in one step. Permanent control of the mill power guarantees optimum and secure utilization. The input material usually only requires one pre-shredding step followed by a sieving step, which is sorting out the organic,and a magnetic separation.

Interchangeable perforated screens will adapt the size of the final product to the optimum for the customer´s pyro-process. Due to the grinding technology, a drying effect of approx. 10 % is given. Additional drying with process waste gas is possible to achieve a higher drying rate. The ultra-fines are dedusted and also dosed to the kiln system.


  • Size reduction from 250 mm to 15 mm in one grinding step
  • Drying effect of 10% during operation
  • Improvement of ignition properties due to a change of physical properties (higher specific surface)
  • Separation from heavy items, FE- and non-FE materials
  • Easy to operate
  • Easy maintenance
  • No knifes
  • Reduction of conventional fuel costs
  • No further grinding step necessary
  • Separation of FE and non-FE materials can be fed back to the recycling process
  • Different output fuel particle sizes for main burner and calciner possible


  • Significant reduction of wear, manpower and electricity costs
  • Reduction of CO2 emissions
  • Requires only two fuel preparation steps
  • Separated FE and non-FE materials can be fed back to the recycling process
  • Reduction of coal consumption


Types of Products:


  • A TEC Rocket Mill RM 2.00 single

 The A TEC Rocket Mill RM 2.00 single has the dimensions of a 20-foot sea freight container and is installed in a frame. This can be completely closed if required and shipped like a shipping container. The mill is equipped with a chamber and is mainly used in case of intended relocation, as well as at lower tonnages. Furthermore, the plant is equipped with a feeder adapted to the mill for the feed material and a separate dedusting.


  • A TEC Rocket Mill RM 2.50 double
The A TEC Rocket Mill RM 2.50 double is equipped with two chambers and is used for the substitute fuel production of high tonnages. The two crushing chambers can be filled separately and ensure a high availability of the machine.
