Embodiment 1

[0023] A device for adjusting the gradation of gypsum powder particles, the device includes a rotary kiln 1, a first reamer 3, a shaker 4, a ball mill 5, a dust collector 6, a second reamer 7 and a storage tank 8, the rotary kiln One end of 1 is provided with an unloader 2, and the unloader 2 is sequentially connected with the first reamer 3, shaker 4, and ball mill 5; according to the needs of the production site and the actual production process, the unloader 2, the first reamer 3. The shaker 4 and the ball mill 5 can be directly connected, or connected sequentially through material conveying pipelines. The plaster of paris enters the first reamer 3 through the unloader 2 of the rotary kiln 1, and the plaster of paris material is pushed to the shaker 4 through the rotation of the first reamer 3, and the material is transported to the entrance of the ball mill 5 through the shaker 4. After the material enters the ball mill 5, the material is pulverized into a certain fineness...

Abstract

The embodiment of the invention provides a device for regulating particle size gradation of gypsum powder. The device comprises a rotary kiln, a first reamer, a shaking lifter, a ball mill, a dust collector, a second reamer and a storage tank; one end of the rotary kiln is provided with a discharger which is sequentially connected with the first reamer, the shaking lifter and the ball mill; the end of the rotary kiln is sequentially connected with the dust collector and the second reamer; the ball mill and the output end of the second reamer are connected to the storage tank; a variable-frequency reamer mechanism is adopted as the second reamer. According to the device, the particle size gradation of the manufactured gypsum powder can be artificially controlled as needed, the fineness range of the gypsum powder is greatly widened, the using property of the gypsum powder is improved, and therefore the particle size gradation requirements of the gypsum powder in different aspects are met.

Description

technical field [0001] The invention relates to a plaster of paris production device, in particular to a device for adjusting the gradation of gypsum powder particles. Background technique [0002] Gypsum powder is widely used in many application fields such as construction, building materials, molds and art models, chemical industry and agriculture, food processing and medical beauty, and is an important industrial raw material. Among them, gypsum used in the production of building materials includes natural gypsum and chemical gypsum. Natural gypsum includes natural dihydrate gypsum and natural anhydrous gypsum. Anhydrite, commonly used in industry is natural dihydrate gypsum. When the dihydrate gypsum is heated to a certain temperature, the gypsum loses part of its crystal water and becomes an opaque white powder, which is called plaster of paris. [0003] Gypsum can usually be processed into gypsum powder using pulverizer equipment. At present, the gypsum powder produ...
