Description

Double-roller for feeding Technical Field The utility model belongs to the field of crushing equipment, and particularly relates to a pair of rollers for feeding. Background The pair roller is widely applied due to the simple structure and low running cost. When the double-roll machine is used, after materials enter the feeding device in the double-roll machine from the hopper, the materials are clamped between the two roll rings, and the materials are crushed to fall from the gap between the roll rings along with the rotation of the roll rings, so that the granularity of sand is related to the gap between the two roll rings. However, the existing feeding device of the roller pair machine consists of an upper frame and baffle plates arranged on two inner sides of the upper frame, wherein the baffle plates are fixed on the upper frame, only a small gap exists between the baffle plates and a roller ring, and the working length of the roller pair machine is approximately equal to the length of the roller ring of the roller pair machine. Because the baffle is close to the edge of the roller ring, the hopper stretches into the feeding device, materials fall down from the hopper, the two ends of the roller ring cannot be participated in the work, uneven wear of the roller ring is caused, after a period of work, the two ends of the roller ring protrude, the materials are broken unevenly, the protruding parts are abutted to each other, the adjustment of the distance between the two roller rings is limited, the roller ring cannot reach the wear limit and is forced to be replaced, and the problem that full utilization cannot be achieved is solved. For this purpose, a pair of rollers for feeding is proposed to solve the above drawbacks. Disclosure of utility model The utility model aims to solve the technical problem of overcoming the defects of the prior art and providing a pair roller for feeding.
