This stuff is boiler slag, which is a recycled product from coal burning plants. When coal is "fired" at over 2500 degrees it melts and produces a by-product called slag. When the slag is cooled through a process called vitrification, it crystallizes, forming sharp, angular granules in a variety of sizes. We reclaim this slag and put it ...

Coal size is further reduced through a sizer. Screening is used to separate different sizes of crushed coal. In this process, coarse and fine coal is separated to accommodate specific markets and industrial usage. Screened coal is ideal for burning in horizontal kilns. Coarser coal is required by customers who burn coal in grate-fired applications.

The design objectives for intermediate coal screening are similar to those for coarser coal, except that the sieve openings must be made significantly smaller. To achieve this, the materials used to define the screen openings (bars, wires, or perforated plate) must also be made smaller, thinner, and more fragile in order to maintain an adequate ...

mixing bins where the various types of coal are stored. The coal is transferred from the mixing bins to the coal crusher where it is pulverized to a preselected size between 0.15 and 3.2 mm (0.006 and 0.13 in.). The desired size depends on the response of the coal to coking reactions and the ultimate coke strength that is required.
