AI Technical Summary
Existing grain grinding equipment uses a single grinding method, resulting in a mixture of coarse and fine lumps, uneven powder particle size, and reduced product quality.
The system employs a dual crushing system, including a screening box and a crushing box. The motor drives the rotating rod to drive the cam to vibrate the screen for screening, and the screw conveyor assembly uses a screw conveyor to send the grains of unqualified particle size back to the crushing box for secondary crushing. At the same time, a servo motor drives an anti-blocking component to prevent the feed inlet from getting blocked.
It improves the efficiency and particle size uniformity of grain grinding, prevents clogging, and enhances product quality and the practicality of the equipment.
