Vibratory Screens McLanahan

Vibratory Screens. Screening is an important part of processing and is used to separate material according to its size. Material is typically fed to a single-, double- or triple-deck screen to make the required sizes. Screens can be considered the cashbox of the operation, because while crushers make the gradation, screens make the specification.

Coal Preparation Plants Colorado.gov

These plants normally practiced hand picking for the lump and egg sizes (more than three inches) and washed the coarser coal (three inches by one quarter of an inch). The fine coal (less than one quarter of an inch) was usually shipped raw. The reject from such a plant was unlikely to exceed ten percent of the run-of-mine (ROM) coal.
