BLOOMS: A Semi-finished product, usually in square (at times in rectangular) section of cross sectional size exceeding 5"x5" (125mm X 125mm). In some of the modern mills, the term bloom is used to cover such products of cross sectional size exceeding 8"x8". These are inputs for producing Heavy sections and Sheet piling section normally by hot rolling.

The advantages of Rolling process are as follows. By rolling, uniform dimensions of the components can be obtained. It uses the same tool in the sense, the same rollers are responsible for the production of various components. Close tolerance is possible for the components in the rolling. high-speed production takes place in the rolling.
20. 13.1.Fineness Fineness is an indicator of the quality of the pulverizer action. Specifically, fineness is a measurement of the percentage of a coal sample that passes through a set of test sieves usually designated at 50, 100, and 200 mesh A 70% coal sample passing through a 200 mesh screen indicates optimum mill performance. …
