Apr 10, 2019 The washing process are as below: 1. Coal blending. Coal blending is to set up a coal hopper with a certain capacity near the wellhead to accept the coal that is raised to ground, to ensure the continuously produced. 2. Coal screening. In coal washing plants, screening operations are widely used in raw coal preparation and washing.

Ultrafine Coal Cleaning Recent studies have found that spirals such as the SX7 can provide an effective gravity-based separation performance for -100 mesh coal. Required volumetric flow rate is around 15 gpm/start and feed solids content should be nearly 15% by weight. Currently, two U.S. coal preparation plants use spirals in this application.
