How to determine the operating speed of the mixer
Thread Content
The operating speed of the mixer should be kept at a distance from the critical speed; different experts have various opinions on this. For example, the \"Mechanical Design Handbook (5th Edition)\” states that when the operating speed is below the first-order critical speed, it should be set at N/Nk
The operating speed should preferably be less than 2/3 of the first-order critical speed. This ensures the safe and stable operation of mixing. Depending on the mixing equipment and operating conditions, the appropriate rotation speed may vary; it is necessary to determine this based on the actual circumstances. .
