DEVELOPMENT OF A MATHEMATICAL MODEL FOR SIMULATION OF COAL CRUSHING

INTRODUCTION At steel plants, for production of coke in the coke ovens the coal received from coal mines is crushed to a desired degree of fineness. Size distribution of the coal charged to the coke ovens has a significant effect on the quality of the coke produced as both the oversize and undersize particles are detrimental to coke quality. Thus, control of the coal crushing operation is a task of considerable
