The principle and advantages of plastic washing machines

Plastic washing machines primarily rely on a rotating shaft inside the machine to mount a reamer (which can be plate-shaped or steel rod). The reamer's rotation strongly agitates the material, generating friction between the reamer and the material, and between the material pieces themselves, thus achieving a cleaning effect. Some machines have threaded steel bars welded parallel to the outer cylinder's generatrix to enhance friction. These washing machines operate at relatively low speeds, typically 300-600 rpm. They are further divided into continuous and intermittent types. Intermittent washing machines (such as common washing drums) are an earlier type and are still in use.

Intermittent operation, continuing until clean, makes it easy to control product quality. However, because it uses continuous, large-volume water injection for cleaning, water consumption is high, production efficiency is relatively low, and labor intensity is high. It is suitable for use in production lines.
