Feed Mixer Auger Parameter Optimization Study

The paper study dairy feed mixing equipment,analysis the vertical TMR feed mixer and the material mixing theory,designed the virtual prototype model of the mixer, also has a materials analysis of kinematics simulation , produced a vertical experimental prototype TMR feed mixer, and a pilot studies to determine the mixer speed and mixing time on the material impact of mixed law of uniformity.This study, the major findings are:1. Designed and manufactured vertical TMR feed mixer experimental prototype, the prototype of the key components - conical auger,using spiral blade two additional leaves 0.25 so the composition of materials. Basic parameters as follows: at the bottom of spiral blade diameter 770mm, auger at the top of spiral bevel angle 60°, stirred at the bottom of two long pitch helical blades 212mm, diameter at the bottom of spiral blades 180mm, blade pitch sweep material 424mm.2. Analysis of the principle of the mixer structure and material composition of the mixed mechanism of experimental prototype to determine the critical speed range of 32 ~ 76 turn / min.3. Using solidworks software designed the virtual prototype mixer,with cosmosmotion carried out the single material in different pitch, speed and location of materials kinematics simulation of materials, analysis the pitch, speed and the location of the materials to impact law materials kinematics.4. The test used orthogonal combination of the second rotation trial, and test results drawn up from an analysis of various indicators of the impact of factors on the response to the impact of the law,determined the best auger combination of speed and stirring time are: speed 80 turn/min, stirring time 6min.
