Design and Experiment of Moving Sieve Jig Sieve Plate Hole Shape

In view of the questions such as existing rectangle hole sieve plate small opening rate,poor permeability,the material easy to plug mesh,and so on,by adopting the combination of theoretical research and experimental analysis method,the sieve plate penetrating mechanism and the formation reason of screening material were analyzed and the rectangular hole opening rate of sieve plate was theoretically calculated.In order to increase the opening rate,by optimizing design of circular arc form wavy hole sieve plate,the theoretical opening rate relative to the straight bar type rectangular hole sieve plate was increased 10.2%,the industrial comparison tests which show that circular arc form wavy hole sieve plate which is of Large opening rate has good permeability,which effectively reduces the Screening material number and ash content.The structure of circular arc form wavy hole sieve plate provides basic referrence for moving sieve jig sieve plate design.
