In the extrusion stage, an extruder is generally used to convey the uniformly mixed PVC powder and quartz sand to a shaping mold. The structure of the extruder currently used is: comprising the following steps: the machine frame is provided with a screw barrel, an extrusion screw is rotatably arranged in the screw barrel, a feeding flow channel is formed between the extrusion screw and the screw barrel, the extrusion screw comprises an extrusion screw feeding section, an extrusion screw fusing section, an extrusion screw conveying section and an extrusion screw compressing section which are sequentially arranged along the axial direction, a feeding port communicated with the feeding flow channel is arranged at the feeding end of the screw barrel, a converging core is butted at the discharging end of the screw barrel, and a converging channel communicated with the feeding flow channel is axially communicated in the converging core. The above-mentioned extruder has the disadvantages: because the hardness of quartz sand is high, the screw barrel, the screw rod and the converging core are extremely easy to be worn by the quartz sand in the material extrusion process, so that the service lives of the screw barrel, the screw rod and the converging core are short, the screw barrel, the screw rod and the converging core are required to be frequently replaced in the production process, and the production and use cost of enterprises is greatly increased.
