摘　　要：针对粒径极小的物料在配料过程中对配比精确度的较高要求,以20世纪90年代初出现的失重式连续配料系统为基础,通过检测合成产品中物料的组分,并与设定的物料配比值进行比较,运用控制器改变其中某种物料流速的设定值而形成串级反馈,构成一种以产品质量为中心的新型失重式连续称重配料系统,解决了超细粉体物料配料速度和精度的矛盾。Aimed at the requested measurement precision in blending process of the loose powder and based on the weight-loss continuous blending system in the 1990′, this paper puts forward a new weight-loss continuous blending system with product quality as a centre, which checks the material compositions of sintetics and compares it with predetermined material mixture ratio. The ratio-cascade feedback control in this system is built up to change velocity of some material flow by using the controller. This method solves the contradictions between burden velocity and precision of superfine powder.
