Abstract：In order to determine the low separation limit of non-pressure three-product dense medium cyclone,test the low separation limit of three-product dense medium cyclone of a coking coal preparation plant by the way of clean coal sieve analysis and accumulated ash, clean coal sieve analysis and distribution curve determination. Compare the advantages and disadvantages, application scope of the three ways.The results show that the low separation limit determined by the three ways all are equal or greater than 0.5 mm.The way of clean coal sieve analysis needs small workload,a short period of time,but it has poor objectivity.The way of clean coal sieve analysis and accumulated ash is greatly influenced by coal slime size composition.The way of the distribution curve determination can determine the low separation limit objectively,which is less influenced by some facts while it needs heavy workload. So the way of clean coal sieve analysis and clean coal sieve analysis and accumulated ash apply to evaluation of equipment performance monthly or quarterly in coal preparation plant,while the way of the distribution curve applies to study of gravity concentration equipment performance and determination of process before new equipment investment in research design department.
