LOOSE MATERIAL DRYING AUTOMATIC CONTROL DEVICE

摘要

concentrating and reprocessing facilities; loose materials drying. SUBSTANCE: modelling of drying process in automatic control device is carried out by three channels (channel 1-fuel consumption - humidity of final product; channel 2 - consumption of initial materials - humidity of final product; channel 3 - vacuum in furnace - humidity of final product) and compensating member is introduced basing on consumption of initial material. Exponential filter smoothing out mismatch between real and modelled humidity of final product is introduced into control system to improve its stability. EFFECT: improved control of drying process. 1 dwg
