Liberation characteristics of coal middlings comminuted by jaw crusher

Full densimetric analyses indicate that mineral liberation of the product crushed by the jaw crusher is better than that by the ball mill at each fraction. For sizes of −0.125 mm + 0.074 mm and −0.074 mm, yields of the product with ash content 11% comminuted by jaw crusher are nearly 20% higher than that by the ball mill.
