BACKGROUND OF THE INVENTION. I. Field of the Invention . The present invention relates to a process for treatment of anthracite coal. More particularly it relates to magnetic separation of previously processed anthracite coal from klinker type ash or cinders, which is an industrial waste product of pre 1960, anthracite treatment centers or coal breakers.
An old engraving of a combined coal breaker and washer in the 1800s. It is from a Victorian mechanical engineering book of the 1880s. This is an early type of coal handling and preparation plant (CHPP, coal handling plant, prep plant, tipple or wash plant) where coal is readied for use.
Coal Preparation If the coal is delivered in form of lumps, the coal preparation may be carried out by 1.Breakers 2.Crushers 3.Sizers 4.Dryers 5.Magnetic Separators 3. Coal Transfer • After preparation coal is transferred to the dead storage by means of the following systems : • …
