Grinding characteristics of coal and petroleum coke/coal blends
ABSTRACT. Petroleum coke (PC) blend with coal is an attractive feedstock for combustion process. The present work investigates the grinding Important Note: If you chose to use different types of coal (having different rank) simultaneously or use coal and Petcoke, remember to grind them separately as per Coal Grinding Cement Plant Optimization

petcoke Cement industry news from Global Cement
Pfeiffer. A MPS 3070 BK type mill has been selected for grinding petroleum coke and coal. The throughput rate for pure petcoke grinding will be 40t/hr with a product fineness of 2% R 90µm. The mill will be equipped with an SLS 2900 BK type classifier. Due to the high abrasiveness of Indian coal, the mill and classifier will be designed with acoals. Pet coke is relatively finer compared to coal. Typically, 20 30 % of coal is above 50 mm in size. Hardgrove Grindability Index (HGI) of pet coke varies 40–55. The specific power consumption for grinding is higher for pet coke, as compared to coal since pet coke has to be ground to a finer level (3).Clinker Manufacturing Using Pet Coke as Alternative Fuel and

Petcoke Use in India’s Iron and Steel Industry CEEW
The iron and steel industry uses petcoke as a feedstock blending with coking coal during the coke making process. The industry only uses low-sulphur (<2.5 per cent) imported petcoke with a blending limit of 15 per cent as the presence of sulphur is detrimental to steel quality. Increase in the sulphur content would require additionalpetroleum coke has nowadays become cheaper than coal mining and coal coke production. Beyond that, the world's resources of high-quality atthracite coal are rapidly decreasing, while oil refinery plants have got a stable raw material base for petcoke production in necessary amount.
