Description

Technical Field

[0001] The utility model relates to the technical field of gypsum powder production, in particular to a grinding mechanism for gypsum powder production. Background Art

[0002] Gypsum is a monoclinic mineral and a hydrate whose main chemical component is calcium sulfate (CaSO4). Gypsum is a widely used industrial and building material. It can be used as a cement retarder, gypsum building products, model making, medical food additives, sulfuric acid production, paper filler, paint filler, etc. The microporous structure and heat dehydration properties of gypsum and its products give them excellent sound insulation, heat insulation and fire resistance. The production of gypsum powder requires multiple processes such as crushing and grinding the gypsum.

[0003] Please refer to the gypsum powder grinding device with announcement number CN218945265U. The patent states that "most gypsum powder production devices in the prior art perform multiple steps separately, which is very inconvenient. They cannot be directly screened after grinding the gypsum. The back-and-forth transportation process easily causes waste of raw materials and has poor practical effect." The crusher provided in the patent can crush large gypsum blocks. The gypsum blocks crushed into small pieces are further crushed by a crushing roller device. After the crushing is completed, they enter the grinding device. The ground gypsum powder falls on the screen. The activity of the screen can realize the classification of the gypsum powder after grinding, thereby integrating multiple steps together.

[0004] However, although the above patent can realize the crushing, grinding and screening of gypsum, the above patent does not provide a structure to protect the edge of the screen. Since the screen is relatively fragile, the edge of the screen is easily damaged by friction with the inner wall of the grinding chamber during the up and down movement, which easily increases the gap between the screen and the inner wall of the grinding chamber, causing gypsum powder that does not meet the production conditions to leak out from the gap between the screen and the inner wall of the grinding chamber, affecting the screening effect and reducing the practicality of the device. In view of this, the present application proposes a grinding mechanism for gypsum powder production. Utility Model Content

[0005] In response to the deficiencies in the prior art, the utility model provides a grinding mechanism for gypsum powder production, which is capable of utilizing a provided protective box to prevent the sieve plate from being damaged due to collisions, thereby enabling the sieve plate to maintain a good screening effect. After a period of use, the sealing plate can be opened and the gypsum that has not been screened out in the protective box can be collected and cleaned using a cleaning window, thereby facilitating the cleaning of large-particle gypsum powder and effectively improving the practicality of the device. It solves the problem that most gypsum powder production devices in the prior art perform multiple steps separately, which is very inconvenient, and cannot be directly screened after grinding the gypsum. The back-and-forth transportation process easily results in waste of raw materials and poor practical effect.
