针对某企业使用着色剂产品后产品颗粒强度大幅度下降、养分含量下降、水分含量上升现象进行分析,发现着色剂用量增大是主要因素。通过调整产品生产原料、半成品质量,提高干燥尾气温度,改变筛分返料筛孔径,提高返料比,增加产品大颗粒比例等辅助方法,使产品指标达到要求。 For a company using colorant products, the product particle intensity decreased significantly, nutrient content decreased, the water content increased phenomenon was analyzed and found that the increase in colorant dosage is the main factor. By adjusting the production of raw materials, semi-finished products, improve the quality of the dry exhaust temperature, sieve sieve back to change the sieve aperture, increase the ratio of return to increase the proportion of large particles of products and other auxiliary methods to meet the requirements of product targets.
