AI Technical Summary
Existing technologies are inadequate for efficiently processing construction and factory waste, particularly bituminous waterproofing membranes, due to the presence of non-recoverable components like hard solid particles, which are not effectively treated by colloidal mills or continuous filters, leading to clogging, incomplete treatment, and high operating costs.
A refiner device with a cylindrical drum and enclosure that allows independent control of rotational and axial movements, combined with heating, to efficiently process thermoplastic composite materials, including bituminous products, by shearing and stretching solid particles and fibers to microscopic sizes.
The refiner effectively processes macroscopic hard particles and fibers, reducing them to dimensions << 100 µm, minimizing wear and maintenance costs, and ensuring complete treatment of polymers and fillers, enhancing the reuse of bituminous materials.
