Coal Preparation

Coal Preparation
Material can be delivered either by truck or railcar. Solid feedstock is prepared to the desired specifications and stored in nitrogen-purged bunkers. The following equipment is available for feedstock preparation:

  • Williams coal and rock crusher
    • Capacity: 4 tons/hr coal or rock to ¼ in.
  • Mikro pulverizer
    • Capacity: 1 ton/hr to 200 or 325 mesh
    • Other bar screen sizes can be purchased
  • Kason classifier
    • Capacity: 4 to 5 tons/hr
    • Screen sizes include 1, 3/4, 1/2, 1/4, and 1/16 in. and 4, 6, 10, 20, 30, 40, 50, 60, 100, 150, 200, and 325 mesh

A steam dryer is available to dry feedstocks before they enter the carbonizer or transport reactor development unit. The objective of drying the feed material is to reduce or eliminate the net production of wastewater, reduce the heat load of the feed, or reduce feed problems that are inherent with excess surface moisture.
