Efficiency of Batch Preparation at Makeevka Coke Plant

Abstract

The operational efficiency of the batch-preparation shop is assessed, in terms of the uniformity of batch quality. The importance of batch uniformity in the production of blast-furnace coal of stable quality is confirmed. Analysis of individual stages of coal preparation permits the development of batch-uniformity coefficients that may be used in assessing the ability to produce batch of stable quality. In an industrial experiment, the mixing efficiency of coal concentrates is determined in dosing, crushing, and transportation of the final batch to the coke shop.
