[0002] Grinding mills are widely used in the grinding and processing of mineral materials in metallurgy, building materials, chemical industry, mining and other fields. Based on the fineness of the material being ground and the fineness of the output material, grinding mills can be classified into six types: pendulum grinding mills, high-pressure suspension roller grinding mills, high-pressure micro-powder grinding mills, straight-through centrifugal grinding mills, high-pressure trapezoidal grinding mills, and three-ring medium-speed grinding mills. However, existing grinding mills still have certain shortcomings in use, such as…

[0003] After grinding, existing grinding mills usually need to transfer the material to a screening machine for screening, which is quite troublesome. Most of them do not have a screening structure, and the larger materials screened out need to be sent back to the grinding mill for grinding. Most of them cannot be recycled. Utility Model Content

Furthermore, by activating the electric actuator, an arc-shaped plate is moved away from one side of the discharge chute, allowing the material on the screen plate to slide into a bucket elevator and be fed into the mill body for further grinding, thus enabling the grinding mill to circulate and grind the material. The specific details are as follows:

[0016] 1. By starting the vibrating motor to drive the screen plate to resonate, the spring is squeezed to rebound, and the ground material is screened. Then, the electric push rod is started to rotate the rectangular frame, tilting the screen plate back and forth, so that the ground material vibrates back and forth on the screen plate, thereby allowing the grinding mill to screen the material.

[0017] 2. By starting the electric actuator, the arc plate is moved away from one side of the discharge chute, and the larger material remaining on the screen plate slides into the bucket elevator. The bucket elevator pours the material into the machine body, where it is ground again, and the grinding mill circulates and grinds the material. Attached Figure Description
