Influence of preheating on grindability of coal ...

01/09/1992  If grindability could be increased by preheating the coal with waste heat, energy costs could be reduced. The objective of this work was to determine how grindability was affected by preheating. The method was to use population balance grinding models to interpret results of grinding coal before and after a heat treatment. Simulation of locked cycle tests gave a 40% increase in grindability. Approximately 40% grinding energy saving can be expected. By using waste heat for coal ...

Preheater In Cement Plant - Cement Plant Machinery Supplier

Our cyclone preheating system mainly consists of a feeding system, preheater, pushing device, hydraulic system, precalciner, and frame. According to the number of cyclones, the preheater can be divided into different stages, generally 2-6 stages. The higher the stage, the more efficient the preheater is. While each stage increases the pressure drop across which the kiln fan must work.
