Analytical shredding systems for QA work are a fundamental preliminary component in the production of substitute fuels.
With primary fuels and finite resources subject to continuous price increases, the significance of substitute fuels continues to rise unabated. For plant operators, this offers first-class potential and attractive prospects for the future.
Businesses that buy in their substitute fuel from external suppliers are faced with two key analytical requirements before putting it to use: pollutant analysis and calorific analysis. To ensure the proper handling of these analyses, a sophisticated sampling system is required.
The processing of waste materials plays an important role with regard to the achievement of the required quality criteria, in particular the shredding of substitute fuels.
Our shredders and automated complete systems guarantee you an optimal preparation of samples to evaluate the quality of your substitute fuels. We set new standards in the area of sampling and process reliability and are passionate about your tasks. Use the leading ERDWICH technology for your success in the substitute fuel market segment.
We offer you two different solutions. On the one hand, the shredder can be used as a stand-alone machine. Depending on the sample size, the compact models M400 for up to 30 liters and the M600 for up to 240 liters are provided. The feed to the system as well as the division after the shredding are done manually. On the other hand, comminution with subsequent division is possible. Here the original sample of around 200 l is manually removed from the furnace, transported to the system and crushed there. The sample division is then carried out.
Very recently the Heating Value Regulation in the German Waste Processing Business Act was abolished. This regulation had made it easier for industrial businesses such as Cement Manufacturers to additionally use refuse derived fuels (R.D.F.) such as old tires as fuels. A prerequisite for this was that the heating value of the waste materials was at least 11,000 kJ/kg. As a result of the change it is expected that annually some 80,000 tons of old tires, which otherwise would have served as R.D.F. will be recycled.
In addition, in future, the high quality of the waste materials used in cement works will be important. They will have to be tested in a laboratory. In order to provide representative sample probes of the R.D.F., it is advisable to employ an automated sample extraction system. This prepares the material for the laboratory analysis so that the product quality and heating value can be evaluated.
System criteria:
- Representative sampling from primary sample quantity, generally 200–250 litres
- Shredding of primary material from approx. 30 mm to the appropriate lab shredder particle size of approx. 5–8 mm
- Homogenisation of the primary sample, to enable the representative sampling of the 1-litre lab sample
- A high degree of process automation, to exclude human sources of error or manipulation
- Automated return of sample waste to the stove feeder system
- Reproducibility and documentation trail for the sampling process
