Experimental Study on the Performance of the Hydrocyclone with Adjustable Underflow Outlet
摘要
Abstract
The mineral processing conditions are often complex,so it has to stop the machine and change the outlet manually for a traditional hydrocyclone with fixed underflow outlet.Such operation affects the total system inevitably.In order to solve the prob-lem,a kind of adjustable underflow outlet characterized by a conical regulating structure has been proposed.The advantage is that it can be regulated on line.The comparison experiments of a 50mm hydrocyclone with the fixed and adjustable underflow outlet have been carried out for analyzing their different separation performance.The underflow density,handling capacity,classification efficiency and separation accuracy have been analyzed thoroughly.Results show that,the separation performance of the hydrocy-clone with adjustable underflow outlet can be improved.Compared with the traditional hydrocyclone,the handling capacity increa-ses by 2.2% ~6.4%;the underflow density decreases by 26.3% ~29.74%;the classification efficiency increases by 7% ~24.57%;and the sharpness index increases by 19.5%.The hydrocyclone with adjustable underflow outlet is suitable for classifi-cation operations under the pressure of 0.1 ~0.14MPa.关键词
