[0002] Sand making machine is a kind of equipment used to crush large pieces of materials into sand particles. It is widely used in medium and fine crushing of various hard and brittle materials such as various rocks, abrasives, and refractory materials. After being accelerated by the rotor, the materials collide and break in the crushing chamber, and the large pieces of materials are broken into fine particles. The impact angle between the material and the peripheral guard plate in the crushing chamber directly affects its crushing efficiency. However, the traditional crusher has complex feed diameter and flow rate, and the peripheral guard plate is fixed and cannot be adjusted. It lacks the ability to perform adaptive crushing according to different feed conditions.

[0044] The motor 6-4 is fixedly connected to the discharge plate 6-2 via a connecting device 6-3.

[0045] The perimeter guard plate angle control strategy is as follows:

[0046] When the particle diameter is 40-50mm, the unloading flow rate is 200-220t / h, and the collision angle of the surrounding guard plate is 36-45°; when the particle diameter is 30-40mm, the unloading flow rate is 220-240t / h, and the collision angle of the surrounding guard plate is 27-36°; when the particle diameter is 20-30mm, the unloading flow rate is 240-260t / h, and the collision angle of the surrounding guard plate is 18-27°; when the particle diameter is 10-20mm, the unloading flow rate is 260-280t / h, and the collision angle of the surrounding guard plate is 9-18°; when the particle diameter is 0-10mm, the unloading flow rate is 280-300t / h, and the collision angle of the surrounding guard plate is 0-9°.

[0047] During operation, the camera 5 first identifies the material diameter and the material discharge flow rate, and the motor 6-4 drives the rotating plate 6-1 to rotate and start discharging. Then, according to the peripheral guard plate angle control strategy, the collision angle between the material and the peripheral guard plate 8-2 is changed by rotating the cylinder 8-4-1. Subsequently, the camera 5 identifies the discharge flow rate, and according to the peripheral guard plate angle control strategy, the motor 6-4 drives the rotating plate 6-1 to rotate, and adjusts the relative openings of the discharge port 6-2-1 and the disc 6-1-1 so that the discharge flow rate meets the peripheral guard plate angle control strategy. Finally, the motor 6-4 drives the rotating plate 6-1 to rotate, and the upper and lower discharge ports 6-2-1 are concentric with the disc 6-1-1, and the discharge is stopped.

It avoids the low crushing rate caused by insufficient crushing when the incoming material diameter and flow rate are large, thereby realizing efficient crushing of the sand making machine. At the same time, it improves the intelligence level of the equipment and avoids repeated crushing caused by low material crushing rate. It reduces manual operation and equipment operation times, and reduces equipment operation and maintenance costs.
