The Hollinger crushing plant is one of the largest and most uptodate plants in Canada. Of steel and concrete construction throughout, high headroom is provided so that, with the exception of a single lift through shuttle conveyors to Nos. 2 and 3 screens, there is gravity flow to all machines (see Fig. 10).
In coal preparation, screening machines serve two purposes: sizing and media recovery. Oftentimes, the initial screening is performed by a scalping screen located outside the plant. This prevents the screens inside the plant from becoming overloaded. The deslime screens make the next cut and most prep plants size to minus 1 mm.
Coal Sizer is a professional coal crushing equipment, mainly used for crushing raw coal, coal gangue, coal coke and other materials.
