Charging system of ceramic non-slurry pelletizing

Abstract

The invention relates to a charging system of non-slurry pelletizing. The charging system comprises a stander, a storage compartment and a weighing compartment; the storage compartment and the weighing compartment are installed on the stander; the storage compartment is arranged above the weighing compartment; and the charging system also comprises a first control valve and a second control valve, and the first control valve and the second control valve are arranged on a communication pipeline between the storage compartment and the weighing compartment; a feeder is arranged between the first control valve and the second control valve. By adopting the first control valve, the feeder and the second control valve, accuracy in charging can be guaranteed, the parameter requirement of a pelletizing machine can be met, and the working efficiency and the product quality can be improved.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a feeding system for dry granulation of ceramics. Background technique [0002] At present, in the field of raw material preparation of architectural ceramics, especially ceramic wall and floor tiles, wet ball milling process is adopted, that is, a spray drying method is adopted. 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 material. 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 violates the...

Problems solved by technology

[0004] However, in the existing dry granulation feeding system, only a single valve is used to control the flow of the powder. In this case, due to the good fluidity of the powder, the single-valve control flow error is large; and the powder is very small and will be hidden in the Therefore, the existing feeding system cannot accurately control the feeding amount of powder; in the process of dry granulation, the control of feeding amount has a great influence on the quality and continuous operation of granulation, and the powder feeding Too much or too little, the granulation parameters must be reset, affecting work efficiency
