Abstract
The invention relates to a method and a device for grinding hot, wet raw material.The invention is particularly suitable for the cement industry and the grinding and simultaneous drying of cement clinker, slag and aggregates. In order to achieve a throughput increase and energy saving, as well as an improvement in the product quality, particularly with mixed cements, there is a simultaneous grinding and drying through a controlled supply of a cooling gas in the upper mill part with a relatively high hot gas inlet temperature in the lower mill part. The cooling gas supplies ensures a predetermined gas-product temperature downstream of the classifier and replaces or significantly reduces the disadvantageous cooling water injection.
