环模制粒模、辊挤压过程影响因素分析

Analysis of Influencing Factors of Ring Die Pelletizing Die and Roll Extrusion Process

环模制粒装备是饲料加工装备使用最广泛、最重要的设备,环模制粒装备中的模、辊直接接触物料,十分容易磨损,为探究磨损机理,根据物料在挤压过程中的状态分为供料区、变形压紧区和挤压成型区,并对挤压过程进行受力分析,计算出成功攫取公式,并通过ABAQUS/Explicit对模、辊辊轧过程进行有限元分析,得到不同摩擦系数和模、辊间隙情况下压辊受力情况,为环模制粒设备设计提供了参考。

Ring die pelletizing equipment is the most widely used feed processing equipment, the most important equipment, ring die pelletizing equipment in the die, roll direct contact with the material, very easy to wear, in order to explore the wear mechanism, according to the state of the material in the extrusion process is divided into the feed zone, deformation compression zone and extrusion molding zone,and the extrusion process of force analysis, calculated by the success of the seizure of the formula, and through ABAQUS/Explicit finite element analysis of the die, roll roll rolling process, and through the ABAQUS/Explicit finite element analysis of the process. Explicit finite element analysis of the die, roll roll rolling process, to get different friction coefficients and die, roll gap situation under the pressure roller force, for ring die granulation equipment design provides a reference.
