Higher rates permitted if justified based on raw water quality, degree of pretreatment, media type, and other factors. Filter media can be single, dual or multi. Single media bed is 24" to 30" deep, and made up of: Clean silica sand, or Clean, crushed anthracite coal.
Further, each coal type, depending on its properties, caused development of distinct methods of production, liquification and reclamation. In the early production of anthracite, coal removed from the mine was transported to coal breakers where it was crushed, cleaned, sized and washed.

Jul 27, 2016· Special Research Report SR-1 The research project on the crushing of anthracite was incorporated as a part of an over-all project on the grindability of anthracite. This phase of the over-all project was originally initiated because several members of the advisory committee and many anthracite engineers are vitally interested in economical methods of crushing the stove and nut sizes of ...
The four ranks are: Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high percentage of fixed carbon and a low percentage of volatile matter. Bituminous: Bituminous coal is a middle rank coal between subbituminous and anthracite. Bituminous coal usually has a high ...

In anthracite's heyday, huge coal breakers dotted the landscape and marked the numerous collieries in northeastern Pennsylvania. Described in 1906 as "enormous preying monsters," breakers crushed and separated anthracite into different sizes, processing it for market. Then, nearly 175,000 anthracite workers supported a million people.
