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.
