Abstract
Description
Technical Field
[0001] This utility model relates to the field of gypsum powder screening and grading technology, specifically a vibrating building gypsum powder fine screening and grading device. Background Technology
[0002] The vigorous development of new wall materials has become a major trend in my country's building materials industry. Building gypsum is one of the important raw materials for producing wall materials. Paper-faced gypsum board is now widely used. On the one hand, it conforms to the trend of developing new wall panels, and on the other hand, it effectively solves the problem of secondary utilization of chemical phosphogypsum waste.
[0003] However, the imperfections in the crushing mechanism of existing screening and grading devices often result in impurities in the gypsum powder or uneven particle size of the crushed gypsum particles, affecting the quality of the final product.
[0004] To address the aforementioned deficiencies, Chinese Patent Publication No. CN214077151U discloses a high-strength, whitening, and environmentally friendly gypsum powder base material grading and crushing device. This device includes a material container with a protective shell inside. A frame is mounted on top of the protective shell, and a first wheel is mounted on top of the frame. A belt is fitted between the first wheel and a first motor, which is fixed to the top of the protective shell. A support frame is located outside the frame, and a vibrating screen is mounted on top of the support frame. The vibrating screen is inclined, with its lower end opposite to the top of the frame. A jaw crusher is located inside the frame, and a hammer crusher is located at the bottom of the protective shell. This invention first performs screening to remove dirt, then jaw crushing, followed by hammer crushing to pulverize large particles. This allows for better grinding and pulverizing of the gypsum powder base material to meet qualified standards, providing higher-quality raw materials for gypsum product production.
[0005] The aforementioned device uses a hammer crusher to pulverize large-particle raw materials during operation, thereby facilitating the production of qualified gypsum powder base materials. However, the hammer crusher in the aforementioned device only pulverizes large-particle raw materials, and the gypsum raw materials are not pulverized thoroughly, resulting in the accumulation of gypsum raw materials inside the equipment. Therefore, in actual use, there will be situations where the gypsum raw materials are not pulverized thoroughly, leading to the accumulation of gypsum raw materials inside the equipment.
