Raw material mixing and grinding device for ceramic dry granulation

Abstract

A raw material mixing and grinding device for ceramic dry granulation comprises a mixing box, a first stirring shaft, a second stirring shaft, and a driving device; the first stirring shaft and the second stirring shaft both penetrate the mixing box, the parts of the first stirring shaft and the second stirring shaft in the mixing box are both provided with blades at intervals; the output terminal of the driving device is connected to the first stirring shaft, the second stirring shaft is connected to the first stirring shaft through a transmission device; and the mixing box is provided with a material outlet. The raw materials are sheared and grinded by two oppositely-arranged rollers, and the blades, which are arranged on the stirring shafts at intervals, can grind the raw materials. Furthermore, the provided raw material mixing and grinding device can guarantee the mixing effect by avoiding the adherence of sticky raw materials; thus the sticky raw materials and poor materials can be fully mixed, the re-conglomeration after grinding is avoided, the mud can be further grinded into fine powder in the post steps of baking and grinding, and the fine powder can be applied to the final dry powder wetting and granulating technology.

Description

technical field [0001] The invention relates to the technical field of dry granulation equipment, in particular to a raw material mixing and crushing device for ceramic dry granulation. Background technique [0002] At present, in the field of raw material preparation of architectural ceramics, especially ceramic wall and floor tiles, wet ball milling and spray drying methods are all used. This method is mainly to add a certain proportion of water to the raw materials entering the factory, and grind them in a ball mill to prepare a slurry with a certain fineness, and then evaporate the water in the slurry through a spray drying tower, so as to meet the production requirements. Uniform size granular powder. The traditional wet process needs to add water first and then remove water, so that the raw material first changes from dry to wet, and then from wet to dry. This process consumes a lot of heat energy, and at the same time increases the emission of carbon dioxide, which ...
