[0022] The following is a reference to the appendix. Figures 1-6 The preferred embodiments of this utility model are described below. Those skilled in the art should understand that these embodiments are merely for explaining the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.

[0023] This utility model proposes an automatic slag separation mechanism for a double-disc grinder. When using this device, the slag collection box is placed below the slag discharge plate. The motor 3 is started, and the motor 3 drives the corresponding pulley 5 to rotate. One pulley 5 drives another pulley 5 to rotate via a corresponding belt 4. A pair of pulleys 5 drives another corresponding pulley 5 to rotate via a corresponding shaft 10. Another pair of pulleys 5 drives another belt 4 to slide. The upper shaft 10 drives a pair of mounting rods 7 to rotate around the corresponding shaft 10. The pair of mounting rods 7 drive the scraper 9 and the extrusion roller 11 to slide in a circular trajectory. The scraper 9 and the extrusion roller 11 slide along the upper side of the arc-shaped filter plate 12. Simultaneously, the pair of mounting rods 7 drive a pair of corresponding gears 13 to slide along their corresponding meshing gear rings 6. The pair of gears 13 in the middle rotates while sliding. The rotating gear 13 drives another gear 13 on the outer ring to rotate. The pair of gears 13 on the outer ring drive the squeezing roller 11 to rotate, so that the squeezing roller 11 rotates while sliding in a circular trajectory. When the slurry is discharged from the grinding mill body 1, the slurry slides along the guide plate 8 into the arc-shaped filter plate 12. When the squeezing roller 11 rotates and slides along the arc-shaped filter plate 12, it squeezes the slurry, and quickly separates the slurry and slag. The slurry flows into the bottom of the collection box 2 and is discharged through the drain pipe. Then, the scraper 9 scrapes the slag squeezed on the arc-shaped filter plate 12 to the top of the slag discharge plate for discharge. The discharged slag falls into the slag collection box for recycling, so that the waste can be collected and treated in a centralized manner, which is beneficial to environmental protection and reduces the impact on the environment. This device is easy to install on one side of the double-disc grinding mill body 1 and does not take up too much space.

In addition, the terms "first", "second", "third" are for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0026] In addition, it also needs to be explained that, in the description of the utility model, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be broadly understood, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the communication between two elements inside.
