    Abstract: The mathematical model and simulation of coal pulverizer has been presented in the paper using first principle mass and heat balance equations based on physical insight. The coal mass flow is modelled based on the mass balance model. The pulverized coal temperature is modelled by considering the coal and the pulverized coal as a lumped thermal mass... Show More

    Abstract: This experimental research portrays the impact of strontium seen on hardness and impact strength of Al-1.0%mn-12%Si alloy. Strontium was added with respect to the amount of silicon present in the alloys (12% of Si; 0.02-0.03% of Sr) and 1.0% manganese which serves as a modifying agent). Higher amount of aluminum and silicon were dissolved and cast ... Show More
