METHOD OF MECHANICAL COMMINUTION OF RUBBER AND A DEVICE FOR ITS REALIZATION Russian patent published in 2004 - IPC

FIELD: heat engineering.

SUBSTANCE: the invention is dealt with the field of recuperation and reprocessing of rubber, namely with the systems of comminution of the worn out tire casings. The method of comminution of rubber provides, that a rotating tire casing is subjected to action of an needle-cutter. A speed of rubber cutting exceeds the speed of distribution in it of a wave front from a single mechanical pulse. The device for mechanical comminution of rubber consists of a worn tire casing and a needle-cutter holding unit, and the needle-cutter is made in the form of a drum, on the surface which and perpendicularly to it there are bundles of a steel wire cable, that are fixed in grooves on the lateral surfaces of replaceable rods in the form of U-shaped sections. The step of the bundles along the drum axis is equal to two diameters of the wire cable the step of rods makes 60-80 mm on the surfaces of the drum, and overlapping of one bundle by other makes 1/3 of diameter of the wire cable. The invention allows to produce homogeneous physical-chemical properties of a thinly dispersible powder of rubber at minimum costs.

EFFECT: the invention allows to produce homogeneous physical-chemical properties of a thinly dispersible powder of rubber at minimum costs.
