Coal grinding to obtain water-coal fuel - globecore

First, we ground “dry” the coal of 10–15 mm fraction using AVS-150 vortex layer device for two minutes. Coal grinding was checked by means of testing sieves. 96% of coal passed through a 316 µm sieve. Next, the sifted sample was run through a 160 µm sieve with a 60% result obtained. And 10% of the sample was run through a 50 µm sieve.
