转速可调的半自磨机可为工艺和设备维护带来好处。对所使用的特定的磨矿设备 ,磨机转速变化对其实用性影响不大 ,或稍稍提高 ,或稍稍降低。开发了几种监测负载体积的方法 ,几种算法已用到磨机给料速率和磨机转速控制中。对实现磨机变速的各种方法的优点和措施进行了考查和比较 Semi-autogenous mill with adjustable speed can bring benefits to process and equipment maintenance. For the particular grinding equipment used, mill speed changes have little or no effect on their availability, either slightly or slightly. Several methods have been developed for monitoring load volume, and several algorithms have been used in mill feed rates and mill speed control. The advantages and measures of various methods to realize the mill speed change were examined and compared
