Abstract:In this paper，the composition and working principle of the single shaft horizontal screw extruder was firstly introduced. Then the screw shaft， filter screen， vacuum device， and discharging device were analyzed and designed. Finally， the rotation speed， production capacity， and pulping concentration were calculated and analyzed. The experimental results indicated that the pulp concentration after extruder treatment could reach 49%， and the production capacity of the equipment could reach 128 t/d. The results showed that the production efficiency of the extruder was increased by improving the design of the single shaft horizontal screw extruder with the pulp concentration increased， and the cost of the pulp transportation process was reduced.
