Machine for processing materials that are liquid, or in the course of processing,Can be converted to liquid state is particularly suitable for processing Plastic or viscous Liquid Polymers

摘要

A multi-stage rotary processor particularly useful as a pump for viscous materials. The multi-stage rotary processor includes a rotatable element having a surface carrying at least one primary processing channel connected to at least one further processing channel and a stationary element providing a complementary coaxial surface arranged with the channels to form enclosed primary and further processing passages. The stationary element also has associated with it an inlet for at least the primary processing passage, outlets for the passages and members extending into each channel for blocking material fed to the processing passages so that liquid material in contact with the rotating channel walls can be dragged forward in each channel. In the primary processing passage the dragged forward material is transferred to the further processing passage for discharge at a uniform pressure and rate.
