Commercial trials have shown that for the coals currently supplied to the works the optimum degree of charge crushing is 76-77 percent below 3 mm. This increases the coke-oven output and leaves the coke quality at its former level. The use of stamped sieves instead of barred gratings in hammer crushers handling gas coals brings about a substantial improvement in their performance. The commercial adoption of a rational crushing scheme based on crushing each coal in the blend only to the degree necessary leads to a reduced crushing load and optimizes the size analysis of the charge for high bulk density without lowering coke quality. Two crushers have been shut down, reducing the over-all motor rating by 1050 kW. By introducing this rational coal-preparation scheme and optimizing the size analysis of the charge, savings of 790,000 roubles/year are being made at the Krivoi Rog Works.
