旋风磨研磨效率优化设计

为了解决旋风磨研磨效率低的问题，通过数值计算和Fluent模型分析，研究其研磨机理，发现旋风磨的风道结构设计不合理，从而导致旋风磨研磨的样品容易在风道堆积甚至发生阻塞。重新设计了风道，风道进气口段与研磨腔体的圆心共线，在风道中间位置设计1个135 °的拐角，此结构使腔体内气流速度从88.7 m/s提升到107．O m/s，而且消除了风道内不良湍流，显著地提高了旋风磨的研磨效率。

Grinding Efficiency Optimization Design for Cyclone Mill

Research on grinding mechanism through numerical analysis and Fluent analysis, the unreasonable structure ofair duct is the reason for cyclone mill lower grinding efficiency. This structure can make sample easily accumulate in theair duct and even occurs obstruction. This paper redesigned the structure of air duct. Air duct inlet section and thecenter of the circle of grinding chamber were the same line. and in the middle of air duct there was a 1350 corner. Thisstructure made the air flow velocity increase from 88. 7 m/s t0 107. 0 m/s. and eliminated undesirable turbulent wind inthe air duct, significantly improved the grinding efficiency of cyclone mill.
