Once the juice arrived in the boiling house‚ it was contained in clarifying vats and lime was added. It was then boiled in cast iron "coppers" of diminishing size. The furiously hot liquid would be skimmed and ladled into the next smaller copper until it reached just the right consistency and was diverted to a wooden trough leading to wooden flats where it was allowed to cool. The slaves who mastered the boiling stage of the refining process were some of the most highly valued workers on a plantation

Answer: Ammouniam Vandrate had a chemical change but it turned out to be a transition metal‚ no other metal. The sulfates had more transition atoms going through the chemical‚ more than an original transition atom normally. Doing this showed me also that iron nitrate is an transition metal as well‚ same with the cobalt‚ copper‚ and zinc nitrate. (5 points) Score 3. Were there any metallic compounds that did not react with either the acid or the base? Write the type of metal‚ based on your examination

Objective The purpose of the Jominy test in this experiment is to determine the hardenability of three types of steels‚ namely EN 8‚ EN 16 and EN 24. Introduction This report will try to illustrate how the hardenability of these types of steels vary and why. This will be done by using the Jominy end quench test on each of the test pieces and then testing the hardness of the particular steel from the quenched end‚ to the end of the test piece. Taking these different points will enable me to find

temprature can be controlled to dry material with moisture of 12%-15% ready for grinding‚ while that for ball mill can only be 3%-4%. 4). Less consumption of metal parts. As there is no direct contact between different metal parts‚ metal consumption and iron content of final product will be reduced a lot‚ which will be good for final product quality. 5). Less noise and dust. Noise can be reduced by 20-25 db comparing with ball mill and dust will be reduced greatly thanks to it’s subpressure design.
