摘要

a jaw crusher, a mineral material processing unit and a method for processing mineral material. the jaw crusher (100) comprises a fixed jaw and a movable jaw for forming a crushing chamber (3) between them which is open at the top, the fixed jaw comprising a first wear part (1) mounted thereon and the movable jaw comprising a chin (4) and a second wear part (2) mounted thereto, the chin (4) being rotatably mounted to a first eccentric shaft (8). the chin (4) is further rotatably mounted to the second eccentric shaft (9) configured to guide the movable jaw stroke to create a movement pattern with a substantially linear crushing stroke, with the eccentricity of the second eccentric shaft (9) is larger than that of the first eccentric axis.
