摘　　要：针对霍尔辛赫选煤厂现有测量重介悬浮液的密度计在生产过程中存在密度波动大、跟踪不稳定、影响产品质量的现状进行分析。阐述了同位素密度计和压差式密度两者的工作原理和构造,结合具体的生产环境和洗选工艺要求提出了全新的解决方法,通过各项数据指标证明,新的解决方案中,重介悬浮液的密度波动仅为0.007 g/cm^(3),有效保证了重介系统洗选产品质量和指标。The present situation of density meter measuring heavy mediu m suspension is analyzed. Based on the working principle and construction of isotope densitometer and differential pressure density, a new solution is put forward, which is proved by various data indexes. The density fluctuation of heavy medium suspension is only 0.007 g/cm3, which effectively ensures the quality and index of heavy medium system washing products.
