Abstract
The invention relates to a roller sleeve of a roller press for uniformly wear-resisting cast-in hard alloy studs, which is characterized in that the wear resistance of the studs is matched with the wear loss of different parts of the roller surface of the roller sleeve, namely: the wear resistance of the hard alloy stud is in direct proportion to the matching principle of the wear loss, and two or more hard alloy studs with the wear resistance are cast on two or more parts with the approximately equal wear loss on the roll surface of the roll sleeve according to the matching principle that the wear resistance of the hard alloy studs is in direct proportion to the wear loss to realize the basic balance of the roll surface wear.

Technical Field

Background
The roller surface of the roller sleeve of the roller press for the existing cast-in hard alloy stud is abraded in a saddle shape, namely: the abrasion of the middle part of the roller surface is larger than that of the two ends, and the middle part of the roller surface is concave to be hyperbolic or parabolic, so that the powder breaking efficiency of the roller press is reduced; the main reason is that the wear of the material on the roll surface of the roll sleeve is non-uniform wear, and the wear resistance of the roll surface is uniform, so the necessary result is saddle-shaped wear.
The invention relates to a roller shell of a roller press for uniformly wear-resisting cast-in hard alloy studs, which is characterized in that the wear resistance of the studs is matched with the wear loss of different parts of the roller surface of the roller shell, namely: the wear resistance of the hard alloy stud is in direct proportion to the matching principle of the wear loss, and two or more hard alloy studs with the wear resistance are cast on two or more wear loss parts on the roll surface of the roll sleeve according to the matching principle of the wear resistance of the hard alloy stud in direct proportion to the wear loss to realize the basic balance of the roll surface wear.
Disclosure of Invention
