WhatsApp: +86 18203695377Control of low speed mills. As PF flow to the furnace is not measured, generally feeder speed is used to estimate the PF flow. However, in ball and tube mills, storage capacity for the coal is large and hence, speed of the feeders does not provide a good indication of the coal flow transported by the primary air to the furnace [9]. The coal ...
