A Study of Coal Washing Spirals Coal Preparation Vol 12

Process design of the Phola coal preparation plant by G.M. Cresswell* Synopsis The 2 360 t/h two module Phola coal preparation plant represents a new era of large plant in the Witbank coalfield designed to extend its life to 2020 and beyond. The plant uses the optimum processing model for Witbank coals, receiving a feed coal size of -50 mm, wet pure coal is 1.2 to 1.7 and for impure coal is 1.7-4.9. In present work, an attempt has been made to study the different characteristics of coal washing by Float-and-Sink test. A design of a washing plant has been made with the help of data collected from this test. The data collected simply shows the washing characteristics of washing of coal from
