Usually, the common (pre-grinding) aquafeed extrusion process flow is as Fig 1. 2.1 Raw material receiving and cleaning. The designed capacity for raw material intake in an aquafeed mill shall be 2~3 times of its production capacity. For materials of different properties, special cleaning operation should be carried out where it is received.
5 Grinding Considerations for Improving Surface Finish
If the goal is to improve the current surface finish from 20 microinch Ra to 17 microinch Ra, then simply increasing the wheel speed and/or reducing the feed rate slightly might be sufficient. However, if a finer surface finish is required, then these five factors should be addressed. 1. Grinding Operational Parameters.
