我公司2 500t/d生产线采用粉煤灰作为铝质校正原料,其配置一台悬挂式螺旋秤,主要由稳流螺旋给料机、计量螺旋给料机、拉力传感器以及电控系统等部件组成。该设备自2006年10月投入运行以来,一直受计量不稳定、大幅度的波动所困扰,无法正常配料使用。1改造原因因螺旋筒中连续通过的物料实际上并非恒速流动,而是随阻力系数和压力的影响而变化。当给料量
The 2 500t / d production line of our company uses fly ash as the raw material of aluminum correction. It is equipped with a hanging screw scale which is mainly composed of steady flow screw feeder, metering screw feeder, tension sensor and electric control system. . Since the device was put into operation in October 2006, it has been plagued by unstable and fluctuating metrology and can not be used normally. 1 reasons for the transformation due to continuous spiral screw material is not actually flow at constant speed, but with the drag coefficient and the impact of pressure changes. When feeding amount
