WhatsApp: +86 18838072829WEBDec 15, 2021 · To create large mass clean coal composites, bulk jigging was done. The process of cleaning the coal can be sped up by eliminating some of the detail in the washing process (, finding a 'cut point' in the jig column). First, a trial is carried out by jigging 15 kg of raw coal and removing 12–18 slices from the jig column.
WhatsApp: +86 18838072829WEBFeb 3, 2018 · Since the jig feed always covers a range of particle sizes, the E p value may vary within the particle sizes. The relationship between sizes and separating efficiency has been reported by Sanders from the detailed testing of a Baum jig treating 750 mm raw coal. The increase in cut density for the smaller size was clearly demonstrated.
