Abstract:
A waste comminuting device includes a comminuting housing (1), a rotor (2) provided with a plurality of protruding peripheral knives, stationary counterblades supported by the comminuting housing, the minimal distance separating each knife from each associated counterblade, during the passage of the knife opposite the counterblade, being equal to an operating clearance, called the cutting size. For each knife (3, 4, 5, 6) and for at least one direction of rotation of the rotor, at least two non-aligned counterblades (7 and 11, 8 and 12, 9 and 13, 10 and 14) associated with the knife are adapted so that the distance separating the leading edge (45) of the knife and the leading edge (48, 56) of a counterblade at the moment when the leading edge of the knife opposes the leading edge of the counterblade, is different from one counterblade (7-10) to another (11-14).
Abstract:
The present invention relates to a material processing apparatus. The apparatus includes a frame including a pair of laterally opposed parallel sides and a base, and at least a first pair of substantially cylindrical material processing rolling assemblies, wherein each pair of rolling assemblies are driven by a hydraulic drive motor assembly, such that using the hydraulic drive motors, the rolling assemblies can be driven at a variable friction ratio.
Abstract:
Methods and apparatus to make rubber crumb particles, are disclosed. An example method comprises rotating a pair of rigid rolls disposed closely adjacent one another via self-aligning bearings that support the rigid rolls with a preset gap therebetween, feeding material between the rigid rolls, and maintaining the preset gap to exceed the elastic limit of the material.
Abstract:
Crushing finely the chipped rubber such as that of waste tire is done by further small number of crushers, and the capture rate of the target size of the rubber particles is improved.With a crusher which finely crushes the chipped rubber (G) such as that of waste tire, the chipped rubber (G) is supplied to a crusher (10a) structured by a rotating roll (12) having relatively rough groove pitch and pluralities of fixed blades (14) each of which has pluralities of grooves forming crushing edges, thus conducting crushing. The rubber particles (G) discharged from the crusher (10a) are again supplied to the crusher (10a) to repeat the crushing to conduct rough-finishing operation. Then, thus roughly-finished rubber particles (G) are treated by similar crushing operation using a rotating roll (10b) having relatively small groove pitch to conduct finish treatment. The finely-crushed rubber particles are classified using a sieve (16) to specified size ranges.
Abstract:
A tire size reduction/wire separation system comprising a drive shaft; a plurality of rotors mounted on the drive shaft, each rotor having axial slots with a rotatable knife removably secured within each slot; and an independent housing supporting the drive shaft and rotors. The independent housing has a central region with stationary knives. The roots and crests of the stationary knives are matingly oriented and respect to the roots and crests of the rotatable knives. The independent housing also has lateral regions including an annual wear ring vertically secured to the axial ends of the rotors. Each lateral region also includes a wear liner with a circular opening with a diameter greater than the exterior diameter of the wear rings.
Abstract:
A process and apparatus for comminuting rubber particles. In this process and apparatus rubber particles at a temperature below the glass transition temperature are introduced into a comminuting device concurrent with the introduction of an inert gas coolant at a temperature below about −75° F. The rubber particles are comminuted in the comminuting device at a rate proportional to the average particle size of the introduced rubber particles to an average size within the range of crumb or powder rubber particles.
Abstract:
FIELD: techniques for processing different materials, mainly elastomers, possibly in the different manufacturing processes. SUBSTANCE: method comprises steps of acting upon material by means of moving cutting tools for creating in working zone ultrasonic-frequency oscillations of material; setting power of drive units at working and processing materials no less than 100-300 kW; selecting revolution number of tool in range 3000-12000rev/min; selecting quantity of cutting edges of tool according to relation ωn, is less than 800, where ω is equal to the angular velocity of tool, n is equal to the quantity of cutting edges of tool; setting attach angles of tool in range 85-95 degrees; removing separate particles of material embedded to cutting portion of tool my means of fluid flow containing gas and (or) liquid; feeding fluid flow by excess pressure material is fed to tool or vise versa in mode of reciprocation motion or start-stop motion. EFFECT: enhanced efficiency of method, increased disposition degree and uniformity of ready product structures.
Abstract:
A method and apparatus for breaking down pieces of material into smaller pieces and for separating out different substances making up the material, one of the substances being a fibrous textile and another being metal, comprising the steps of subjecting the pieces to a series of dismemberments to produce progressively smaller pieces falling within a predetermined size range; separating the smaller pieces into a plurality of fractions, each fraction including pieces within a predetermined size range; and subjecting each fraction to a flow of air calibrated to cause separation of the fibrous textile material from the pieces.
