Abstract

Flow functions and time consolidation effect of CEM Ⅱ/A-LL 32.5R Portland limestone were analyzed based on Jenike theory and powder flow tester (PFT). Wall friction tests were carried out using five kinds of materials of 304/2B stainless steel, Tivar plastic, mild steel, rubber and PTFE tape. The results show that the flowability of materials becomes weak by time consolidation effect. The cement wall friction angle is the smallest taking 304/2B stainless steel as wall materials. According to diagrams of flow factor and overall flow hopper half angle function, the maximum half hopper angles of conical hopper and wedge hopper made by mild steel wall materials are respectively 5 and 15°,and the minimum open size that is outlet diameter and exit slit width are 0.112 and 0.057 m respectively.
