The cutter holder with the blades rotates along with the main shaft simultaneously in the operation process of the screw conveyor, and rotationally cuts long-drum-shaped or double-drum-shaped materials into materials of about 80 meshes, and then the materials are sent to the air supply pipeline. Therefore, the risk of blockage of the air supply pipeline is reduced, and the anti-blockage effect is achieved.
Further, the vibrating screening device is a GFBD-A swing screen of high-grade mechanical products of GmbH in Xinxiang city.
Further, the crushing system is a GFJ300 efficient crusher of Kunshan Qianwei powder equipment Limited.
Since the technical scheme is used, the beneficial effects of the utility model are that:
1. the utility model discloses replace the rubbing crusher by the conical body that has the blade and smash, the conical body is installed on the main shaft and is located screw conveyor barrel exit simultaneously, provides kinetic energy by the screw conveyor motor, has reduced the energy consumption.
2. The utility model discloses avoid being the bulky material pile of long drum form or twin drum form in the wind send the pipeline, block up the pipeline, reduced the maintenance cost, improved the productivity effect.
3. The utility model discloses smash the material with the conical body that has the blade, kibbling material size is suitable, has effectively improved the product yield, has also avoided the pollution to the environment moreover.
In a word, the utility model overcomes the defect among the prior art, can effectually prevent that pregelatinized starch from blockking up the problem of pipeline to still have the advantage that the energy consumption is low, product quality is stable, product yield is high.
