FIELD: disintegrators and devices for crushing.
SUBSTANCE: invention can be used in mining, metallurgical and other industries, in particular, in gold ore crushing. Ore crushing line contains mill 1 of self or SAG first grinding step with trommel screen 2 and discharge devices for above trommel screen product 3 and under trommel screen product 4, drum-roll mill 5 for the second grinding stage, ball mill 6 for the third grinding stage and set of cyclones 7. Distinction of ore grinding line versions consists in varying classification schemes and movement directions of products from the mills of different stages of grinding.
EFFECT: variable hardware-technological schemes of ore grinding line ensure higher efficiency, lower power consumption, as well as reduction of capital and operating costs.
