Shale ceramsite production and preparation method

Abstract

The invention relates to the technical field of shale ceramsite preparation, in particular to a shale ceramsite production and preparation method, which comprises a support seat, a conveying mechanism, a screening mechanism, a grinding mechanism and a dust falling mechanism. According to the invention, crushed shale particles are screened in a mode that a conveying mechanism and a screening mechanism are combined, so that the shale particles with the size meeting the size of shale ceramsite are screened out in a conveying process while the shale particles are synchronously screened in the conveying process, so that the problem that the working process is increased due to two steps of conveying and screening is avoided; and shale particles with the diameter smaller than 5 mm do not need to be conveyed after being sorted out, and the shale particles with the diameter smaller than 5 mm are directly ground into powder with the diameter smaller than 0.074 mm through a grinding mechanism to be output, so that the problem that the environment is dirty and messy due to flying dust raising in the re-conveying process of the shale particles with the diameter smaller than 5 mm is solved.

Description

technical field [0001] The invention relates to the technical field of shale ceramsite preparation, in particular to a production and preparation method of shale ceramsite. Background technique [0002] Shale ceramsite is made of purple sand shale as the main raw material. Compared with clay ceramsite, shale ceramsite has higher strength, stronger earthquake resistance and high temperature resistance, and is more suitable for building materials. Shale ceramsite Most of the shale pellets are produced by crushing, screening, calcining, cooling, screening and a series of processes from large shale raw materials. [0003] At present, when the crushed shale particles are screened, the shale ceramsite with a particle size of 5-20mm is conveyed after being screened by the screening cylinder, and then transported to the drying box for drying and screening. The shale particles with a diameter of less than 5mm are transported to the grinding mechanism for grinding until the ground sh...

Problems solved by technology

[0003] At present, when the crushed shale particles are screened, the shale ceramsite with a particle size of 5-20mm is conveyed after being screened by the screening cylinder, and then transported to the drying box for drying and screening. The shale particles with a diameter of less than 5mm are transported to the grinding mechanism for grinding until the ground shale is screened out from the aperture with a diameter of 0.074mm. The shale particles need to be divided into two steps of transportation and screening, which increases the production process and time of shale ceramsite, and the screened shale particles with a diameter of less than 5mm are sent to the grinding mechanism due to the shale particles There are small powdery shale particles, so that the flying dust is raised during transportation and the working environment is dirty
