[0033] In actual operation, the operator first pours large PTFE particles into the wetting hopper 1 and sprays water onto them to ensure that water adheres to the surface of the large PTFE particles. Driven by the first lifting component, the water-coated PTFE particles rise with the first spiral disc 6. During this process, excess water flows out through the drain hole 12 on the first guide pipe 3. Due to the design of the water guide pipe 13, the excess water does not slide off the outer wall of the first guide pipe 3 but is guided by the water guide pipe 13 to drip towards the return water hopper 14. Then, the moistened PTFE particles leave from the outlet of the first guide pipe 3 and fall into the discharge hopper 14 under the guidance of the discharge pipe 11. In the mixing hopper 19, during the falling process, the operator can simultaneously pour other powdered ingredients into it. This causes the powdered ingredients to adhere to the outside of the moist large PTFE raw material and be lifted by the second lifting component. During this process, excess powdered ingredients can fall down through the holes 26 on the second spiral disc 24. Finally, the large PTFE raw material with powdered ingredients attached can be recovered and then melted. This process alleviates the problem of small-diameter or powdery materials settling at the bottom of the large PTFE raw material and other materials, ensuring that the final melted material maintains a uniform texture distribution without the need for further stirring.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
