In the UK, the majority of coal mills on existing power plants are fitted with static classifiers and improvements to these offer a limited means of improving the fineness of the ground product from the coal mills. A better solution is to exchange the static classifier for a dynamic (or "rotary") type.
sized material is not reentrained into the air and coal stream entering the classifier. PERFORMANCE Classifier technology in the Power Industry has improved significantly with the advent of rotating classifiers. Compared to mill operation with a statictype classifier, the SLS clas sifier offers a number of performance advantages.
Efficient classification is particulary important in power station applications; a steep product particle characteristic curve ensures that optimum combustion is achieved in the boiler while keeping emission rates at a low level. Loesche dynamic classifiers can be fitted to any type of coal mill.
