As one of the four major fodder machinery, sawdust pellet mill is very important for the fodder production. For sawdust pellet mills at home, they have problems like unreasonable structure, lower working efficiency or higher energy consumption. Due to these defects, suppliers of sawdust pellet mill at home are hard to explore the foreign markets.
Based on the reality, FTM Heavy Machinery makes the systematic study for optimizing the mechanism and performance of saw dust pellet machine. Here comes the important conclusions. By analyzing the distribution of material layer in granulation chamber, we can find that the thickness change of material layer in feeding area can directly influence the working efficiency, energy consumption and service life of saw dust pellet machine.
Through the above relationship, we deduce the theoretical formula, which can account the best thickness of materials in feeding area. By analyzing the pressure on die holes, we establish the mathematical model and reach the conclusion that extrusion force on die holes can change in exponential form along with changes of Poisson's ratio, friction coefficient and draw ratio.
By analyzing the simplified pressure model of die hole, we make the finite element force-stucture analysis. As results show that, greater the chamfer of feeding mouth, smaller the pressure on die hole. Since raw materials are much easier to be suppressed, service life of ring die is correspondingly prolonged. These findings are important, since they can make the sawdust pellet mill more and more excellent. Click website to see price!
