2. 工作原理

旋转干燥机的工作过程可分为以下几个阶段：

1. 物料进料

• 湿物料从滚筒高端进入，由于滚筒倾斜（通常1°~5°），物料在重力作用下缓慢向低端移�?span class="ds-markdown-cite" style="vertical-align: middle; font-variant-numeric: tabular-nums; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; box-sizing: border-box; cursor: pointer; background: rgb(229, 229, 229); border-radius: 9px; flex-shrink: 0; justify-content: center; align-items: center; height: 18px; margin-left: 4px; padding: 0px 6px; font-size: 12px; display: inline-flex; position: relative; top: -2px;">1、�/p>
