Ceramic raw material suspension granulating equipment

Abstract

The invention provides ceramic raw material suspension granulating equipment. The ceramic raw material suspension granulating equipment comprises a feeding device and a granulating suspension tower, wherein the upper part of the granulating suspension tower is of a cylinder structure, and the lower part of the granulating suspension tower is of a cone structure; an air guide groove is positioned at the boundary of the cylinder and the cone of the granulating suspension tower, and is uniformly distributed along the circumference of the cylinder; the pressure air is produced by an external high-pressure suspension fan, and the upward suspension force is produced by the air guide groove; under the action of the suspension force, the microparticles are gradually agglomerated, adsorbed, gradually balled and increased, so as to form a particulate powder; when the weight of the particle is greater than the suspension force of air flow, the particulate powder reaching the technology requirement can flow out of a material outlet. When the powder is prepared by the ceramic raw material suspension granulating equipment, the defect of high energy consumption and high cost by the existing wet powder technology for powder preparation can be overcome; the technical problems of unreasonable distribution of the powder particles, poor fluidity, and too large capacity weight of particle in the existing dry type 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...
