FIELD: disintegrators and crushing devices.
SUBSTANCE: invention relates to crushing equipment in mining and other industries for crushing large lump and medium-lump rocks. Rock is loaded into crushing chamber of a jaw crusher for crushing. Lumps of rock are broken by their clamping between jaws of cyclic moving jaw working stroke to produce in crushing chamber volume a mass of pieces of commercial fractions. Through slot between jaws, rock is unloaded during non-working stroke of jaw. Strikers are mounted in jaw. At moment of pressing rock pieces on strikers, drive of strikers is activated. Strikers act on rock pieces pressing on them in a point cyclically-impact manner. When said pressure is removed, drive of strikers is switched off and movement of strikers stops.
EFFECT: higher efficiency of crushing.
