Granularity homogenization method of refractory aggregate of various size fractions

Abstract

Aiming at function and utilization requirements of refractory aggregate in indefinite-form refractory products and definite-form products after refractory aggregate of various size fractions achieves premixing and granularity homogenization, the invention provides a granularity homogenization method of the refractory aggregate of various size fractions. The granularity homogenization method of the refractory aggregate of various size fractions includes the following steps of adding broken refractory aggregate (15mm-14mm, 14mm-13mm, 13mm-12mm, 12mm-11mm, 11mm-10mm, 10mm-9mm, 9mm-8mm, 8mm-7mm, 7mm-6mm, 6mm-5mm, 5mm-4mm, 4mm-3mm, 3mm-2mm, 2mm-1mm, 1mm-0.5mm, 0.5mm-0mm) to a weighting type distribution bin, adding the refractory aggregate to a moving trolley through a feeding machine according to a certain proportion, enabling the refractory aggregate to enter a mixing machine through the moving trolley to be blended and premixed, and measuring and packaging the refractory aggregate through delivery equipment, wherein deironing and superstrong negative pressure dust absorption treatment are conducted on the premixed refractory aggregate in the process of delivery, and the content of iron and other impurities in the refractory aggregate is further reduced. Therefore, stability of each indicator of the premixed refractory granularity-homogenized aggregate is guaranteed.

Description

technical field [0001] The invention relates to a method for homogenizing the particle size of refractory aggregates of various particle sizes, in particular to a preparation method of refractory aggregate premixed ingredients of various particle sizes with low iron and low impurities. Background technique [0002] At present, domestic unshaped refractory products and shaped refractory products, the preparation of refractory aggregates in the production process is usually: use crushing and screening to obtain several particle size ranges for production (15 ~ 10mm, 10 ~ 8mm, 8 ~ 5mm, 5 ~ 3mm, 3 ~ 1mm, 1 ~ 0mm) refractory aggregates, without premixing ingredients, directly participate in the batching and mixing of downstream finished product production. The refractory aggregate produced by this preparation process has a wide range of particle sizes, and raw material suppliers use different crushing equipment to obtain refractory aggregates with different particle size distribu...
