Ceramic raw material suspension granulation device

Abstract

The invention provides a ceramic raw material suspension granulation device comprising a feeding device and a granulation suspension tower; the upper part of the granulation suspension tower is a cylinder, the lower part of the granulation suspension tower is of a cone structure, and an air guide groove is positioned at the junction of the cylinder and the cone of the granulation suspension tower;pressure air which is evenly distributed along the circumference of the cylinder and generated by an external high-pressure suspension fan passes through the air guide groove to generate upward suspension force, under the action of the suspension force, micro-particles are continuously aggregated, adsorbed and gradually pelletized to be increased to form particle powder, and when the weight of the particles is larger than the airflow suspension force, the particle powder meeting the technological requirement flows out of a discharging port. When the granulation device is used for preparing the powder, the defects of high energy consumption and high cost of a wet powder process for preparing the powder can be overcome, and the technical problems of unreasonable particle distribution, poorflowability and overlarge particle volume weight of powder prepared by a conventional dry process technology are solved.

Description

technical field [0001] The invention relates to ceramic raw material suspension granulation equipment, which belongs to the field of raw material processing equipment in the ceramic industry. Background technique [0002] At present, when the ceramic industry prepares powder particles, one is the wet powder making process, that is, firstly put the raw material into the ball mill and add 32-35% water to finely grind it into a slurry, and pump the prepared slurry into the spray dryer. Use hot air to dry the mud to 6-8% moisture to make pressed granule powder. The particle size of the powder is distributed in the range of 18-100 mesh sieve. The particle content in this range reaches 90%, and the bulk density is about 0.90g / cm 3 , The powder produced has regular particles, good fluidity, and appropriate bulk density, which is convenient for subsequent molding needs. Its disadvantages are: due to the evaporation of a large amount of water, a large amount of heat needs to be con...
