大颗粒尿素在生产过程中,因尿素粒度、温度、粉尘以及贮存等因素的影响,易出现尿素产品结块现象,也造成尿素产品优级品率在80-95%之间波动,经3年多的生产总结和技术改造,在对结块的现象和原因深入分析,采取相应技术措施在设备结构和工艺指标两个方面进行技术改造和不断调整,取得了很大成果,尿素优级品率保持在98%以上。 Large particles of urea in the production process, due to the impact of urea size, temperature, dust and storage and other factors, prone to agglomeration of urea products, also contributed to the urea product excellent grade rate fluctuations between 80-95%, after 3 years More production summary and technological transformation, in-depth analysis of the phenomenon of caking and to take appropriate technical measures in the two aspects of equipment structure and process indicators for technological transformation and continuous adjustment, and achieved great results, urea, excellent grade rate Maintain above 98%.
