摘要
硫酸钾粉料粒度较细,国内利用挤压来实现造粒的很少。挤压过程简单,但控制范围还需要探索,试验利用公司的造粒项目试机,对挤压造粒的工艺控制范围做了探讨。探讨范围包括粉料粒度、水分、挤压机运行参数,找到最佳生产条件。
The granularity of potassium sulfate powder is relatively fine,and there is very little granulation by extrusion in China. The extrusion process is simple,but the control scope needs to be explored. This experiment used the company's granulation project to test the process control scope of extrusion granulation. The scope of discussion included powder granularity,water,running parameters of extruder,and finding out the best production conditions.
