Function of classifier in coal mill.With adequate mill grinding capacity a vertical mill equipped with a static classifier is capable of producing a coal fineness up to 995 or higher 50 mesh and 80 or higher 200 mesh while one equipped with a dynamic classifier produces coal fineness levels of.

mill types. The classifier designed to maintain a limited class of particle sizes and to provide a well-distributed air-coal flow for delivery to the burners [2]. The classification efficiency can be defined as the ratio of the mass of the ground coal entering the coal classifier to that exiting the classifier to the coal burners. CoalJan 23, 2018· Fig. 7 shows the results obtained by retrofitting dynamic classifiers to existing plant. Tranfer of product to the burners. Pulverised coal that passes through the classifier is carried to the burners by the primary air flow. Along the way it is mixed with secondary air to achieve the required coal/air ratio.

pulverize the coal by impact and attrition. The pulverized coal is then conveyed by air to centrifugal classifiers. Properly sized pulverized coal exits the classifier into coal piping for transport to the furnace. Oversized pro- duct is, however, separated and returned to the mill for further grinding.Typical coal capacities up to 200 tph treating -1.4 mm + 0.250 mm feed. Typical hematite ore capacities up to 250 tph treating -0.300 mm + 0.075 mm feed Key aspects High-capacity, compact design accommodates any plant layout. Advancements in channel spacing and width, along with the ability to operate using minimal power and water, mean that

There have been very few conversions of UK coal mills from static to dynamic classifiers. But test experience with a dynamic classifier at Powergen's Ratcliffe-on-Soar power station has demonstrated significant fineness gain, especially at the coarse end of the particle size distribution curve, and minimal effect on mill coal throughput and operability, with greatly reduced in vibration levels.The classifier with the non-swirling inlet demonstrated a larger cut size than that with the swirling inlet when the impeller was stationary (~ 0 r⋅min-1). As the impeller rotational speed increased, the cut size of the cases with non-swirling and swirling inlets both decreased, and the one …
