Description

Technical Field

[0001] The utility model relates to a new type of corn crusher, belonging to the technical field of crushers. Background Art

[0002] A corn crusher is a mechanical device used to crush and pulverize corn or corn-related materials, and it is widely used in fields such as agriculture, feed processing, biomass energy production, and chemical industry. The working principle of the corn crusher is to extrude and shear the corn through two pairs of relatively rotating rollers. After the corn enters the crushing area from the feed inlet, it is gradually crushed into smaller particles or powders under the action of the counter-rollers. Factors such as the rotational speed of the counter-rollers, the gap between them, and the feeding speed of the corn will all affect the crushing effect.

[0003] However, the feeding mechanism of the existing corn crusher cannot operate independently, and the feeding amount cannot be controlled. When the front-end equipment feeds too fast, it will cause the crushing rollers to bear too much load, resulting in equipment failures such as motor overload and damage to transmission components. It may also cause uneven particle sizes and imbalanced component ratios of the crushed materials, affecting product quality; moreover, the two crushing rollers of the existing corn crusher rotate synchronously relative to each other, and the crushing effect of the materials is not good.
