Numerical simulation of mineral microelement licking block press forming

For improving the quality of mineral microelement licking brick, the press forming process of mineral microelement licking brick was simulated with finite element analysis software MSC.Marc2007. The flow behavior of granular materials and dense laws in the process of pressing was analyzed. Based on the simulation result, the reasons for quality defects were found and the size of the green body was forecasted. Distribution of compacted density of mineral microelement licking block was non-uniform in the process of pressing forming and the maximum density was in the outer edge of the top of the green body. As the compressive pressure increases, the compacted density gradually rises and turns even gradually, the optimum compressive pressure was 100 MPa. The simulation results consistent with experimental results well, so it can provide theory reference for practical production.
