Further, this production system also comprises the ball mill pulverized respectively hard coal and rhombohedral iron ore and the platform scale of weighing to clay/kaolin, heavy metal sewage sludge, hard coal powder and rhombohedral iron ore powder.
Further, the discharging order number of described ball mill is 100-150 order.
Further, described platform scale is small-sized weighbridge.
Further, described first stirrer is single-shaft stirring machine.
Further, described second stirrer is biaxial rneader.
Further, described wheel roller is two running roller mills.
Further, described tablets press is pair roller type Squeezinggranulator.
Compared with the various methods of existing improvement heavy metal sewage sludge, the utility model has following beneficial effect: this production system passes through stirrer, wheel roller and tablets press are by heavy metal sewage sludge and the fully broken mixing of other raw material, dispersion and fining also extruding is made into haydite raw material, so that be fired into haydite grog and as roadbed material, aggregate, light cinder brick stopping composition and for raw material required during manufacture of cement, efficiently utilize heavy metal sewage sludge, except poison is thorough, reliably, technique is simple, eat mud amount large, heavy metal contaminants can be administered simultaneously, low production cost, reduce taking land resources in environment protection process, Least-cost.
