Publication number: 20080251619Abstract: The invention relates to a shredder comprising a hopper in which industrial waste is deposited. The base of the hopper is equipped with a waste-shredding rotor, while one of the longitudinal edge thereof, which are parallel to the axis of the hopper outlet, is equipped with a longitudinal row of fixed blades which are distributed uniformly along said edge. According to the invention, spaces are provided between the aforementioned blades to enable the passage of moving blades which are mounted to the rotor by means of supports. In addition, half of the fixed blades are disposed at a greater height than the other half, using an alternating arrangement, such that the moving blades act first on one half of the blades and immediately thereafter on the other half, thereby producing a scissors-type effect which facilitates cutting and extends the useful life of such blades.Type: ApplicationFiled: April 29, 2004Publication date: October 16, 2008Inventors: Adolfo Lopez Aguayo, Avelino Encina Canal
