    Abstract: A partially releasable disc for processing recycling materials in general. More specifically a disc that is sufficiently flexible to function in heavy machinery without excessive wear while maintaining sufficient stiffness to avoid excessive fluctuations, wobbling, or other undesired excess deflection in the disc. An outer flexible portion may be wrapped around a less flexible core. A disc may comprise a plurality of outer impacting elements configured for engaging materials to be classified and propelling the materials in a conveying direction when a core is rotated. For ease of replacement, when the flexible portion is worn or damaged, the flexible portion may be removed without necessarily removing the inner core, saving labor and equipment expense when maintain a screen, such as the separation screens used for sorting recycled materials.

  • Patent number: 8708878
    Abstract: Conventional art has a structure consisting of a roll axis incorporating a structure of fine pores, and a roll unit provided around the outer circumference of a roll axis, wherein internal pressure of the roll axis is dispersed to the roll unit to make a fluid (gas-liquid) suction action, thus reducing the pressure loss and obtaining even distribution of the fluid (gas-liquid). As such, instead of a tubular roll axis, the structure of a roll axis is made fin-shaped or groove-shaped to maximize the action surface area that works on the inner pressure of the roll axis of the roll unit. However, other problems such as inefficiency of the fluid (gas-liquid) suction action and lack of mechanical strength of the roll axis remains.

  • Patent number: 6792859
    Abstract: A rotating drum in which, when the rotating drum is rotated at high speed, there is no offset between divisional drum parts, there is little imbalance, and a moment of inertia for rotation is small. A drum main body is divided into four drum parts whose cross-sectional configurations orthogonal to an axis are fan-shaped. Female projecting portions and male projecting portions are formed at a pitch dimension having a predetermined fit-together tolerance. Thus, the drum parts can be assembled together with a certain amount of leeway at a time of assembly. After the four drum parts have been assembled together, wires are press-fit in from an end surface side of the drum main body so as to tightly fasten the drum parts. Because the assembled drum main body defines configurations of the drum parts to have point symmetry, imbalance can be made small.
