In the business year 2013/2014, German agriculture used considerably more lime fertiliser than in all previous years. Clearly, more and more farmers...
The kiln hood of a rotary kiln in a cement plant connects the hot area of the kiln with the clinker cooler and is therefore always exposed to high thermal and process-related stresses. In recent decades, these loads have steadily increased in consequence of the use of alternative fuels and thereby induced higher process temperatures. For system builders, this means an enormous design effort, when rotary kilns are modernized.
For the production of plaster products natural gypsum, synthetic gypsum or a mixture of both are calcined. Depending on the production process two different modifications of the hemihydrate CaSO4 x ½ H2O are obtained. ...
Balances were used to determine the effect of the contents of CaCO3, MgCO3, water and inert matter in limestone, the air excess number, the kiln wall losses and the residual CO2 content on energy consumption and CO2 content in the flue gas.
The efficient implementation of accurate gravimetric dosing system for material feeding or blending in cement plants require both, a reliable mechanical platform and a robust, precise and ergonomic control system. ...
Materials used for co-processing typically consist of pre-processed liquids or solids in the form of chips, pellets of fluffy crumbs. However, the use of liquid and solid alternative fuels in cement kilns is bringing new danger. ...
CEMBUREAU, the European cement association, and ETRMA, the European Tyre & Rubber Manufacturers association, are calling upon the EU to review Annex II (Recovery operations) of the Waste Framework Directive (WFD) (2008/98/EC) by implementing improvements in scientific and technical progress in this area in order to support waste treatment options which combine both energy recovery and material recycling. ...
