Abstract

The invention discloses a pellet crumbler which comprises a fast roller and a slow roller, wherein the slow roller and the fast roller rotate oppositely. The pellet crumbler is characterized in that the slow roller and the fast roller are respectively provided with a belt wheel, transmission between the slow roller and the fast roller is achieved through a belt, the belt twines the outer side of one belt wheel positively and twines the outer side of the other belt wheel reversely, the belt is provided with a tension mechanism, and the diameter of the belt wheel of the fast roller is smaller than that of the belt wheel of the slow roller. Through the pellet crumbler, the adjustment range of a gap between the fast roller and the slow roller is large, gap adjustment is accurate and controllable, transmission is reliable, the frequency of replacement of the rollers is reduced, the maintaining cost is low, and operation is convenient and fast.

Description

technical field [0001] The invention relates to a feed processing equipment, in particular to a granular feed grinder. Background technique [0002] The existing granulator uses a motor to drive the fast roller to rotate through a belt drive, and the fast roller drives the slow roller to rotate through a pair of gears, so that the fast and slow rollers rotate in opposite directions to achieve the purpose of crushing the material; the position of the slow roller relative to the fast roller is adjustable , through the gap adjustment to meet the purpose of crushing particles of different particle sizes, the gap between the fast roller and the slow roller is adjusted by adjusting the positions of the two ends of the slow roller respectively, and the size and uniformity of the gap adjustment are determined by visual inspection. [0003] The existing granulator has the following defects: [0004] 1. When the gap between the crushing rollers is adjusted, the center distance of the...

Problems solved by technology

[0004] 1. When the gap between the crushing rollers is adjusted, the center distance of the meshing gears changes accordingly, and the gear pair is in an abnormal meshing state for a long time, and even disengages during operation, which is very easy to damage the gears;

[0005] 2. Due to the limitation of the minimum center distance of the gear pair, when the rollers are worn for a period of time, the gap between the rollers increases, but the center distance cannot be reduced. In order to ensure the crushing effect, new rollers can only be replaced frequently, resulting in great waste
