Abstract:
The present disclosure relates to a material reducing machine convertible between a grinding configuration and a chipping configuration. The material reducing machine includes a rotary component that is rotatable about an axis of rotation, the rotary component defining a grinding configuration boundary that extends at least partially around the axis of rotation. The material reducing machine also includes a plurality of hammers secured to the rotary component, the hammers including end portions that project outwardly beyond the grinding configuration boundary of the rotary component. Furthermore, the material reducing machine includes a boundary enlarging structure that mounts over the rotary component, the boundary enlarging structure defining a chipping configuration boundary that extends at least partially around the axis of rotation when the boundary enlarging structure is mounted over the rotary component, the chipping configuration boundary being positioned outside the grinding configuration boundary. The boundary enlarging structure is not mounted over the rotary component when the material reducing machine is in the grinding configuration and the boundary enlarging structure is mounted over the rotary component when the material reducing machine is in the chipping configuration.

Abstract:
The device according to the invention relates to an autogenous rotor that rotates about an axis of rotation, which rotor is provided with at leas one guide member for accelerating material, which guide member is associated with a chamber member where an autogenous bed of material builds up, with the aid of which guide member material is guided into a spiral path in the direction of said chamber member where said accelerated material impinges o said autogenous bed at a predetermined impingement location, after which said material moves from said impingement location along said autogenous bed in the direction of said tip, under the influence of centrigugal force, where said material is propelled outwards from said rotor.
Abstract:
A synchrocrusher for making a material collide in which the rotor is designed with a symmetric configuration; that is, the rotor contains equal numbers of respectively forward and backward directed guide members and co-rotating impact members which are arrranged, as associated (synchronized) pairs, in each direction of rotation; which pairs are circumferentially disposed uniformly at equal angular distances around the axis of rotation with the forward and backward directed configurations mirror imaged (symmetrically) to each other. By combining or joining together pairs of respective forward and backward directed guide and co-rotating impact members, in respective guide and impact combinations and guide and impacts units, a supersymmetry configuration is achieved, which is very effective and allows for many interesting synchrorotor configurations.
Abstract:
The invention relates to a treatment line and to methods and devices for destroying workpieces that are shaped like circular blanks. Such blanks are, for example, circulated as coins and they have to be obliterated reliably, verifiably and at low costs partially in large amounts once they are removed from circulation. To this end, the invention provides a device for treating workpieces that are shaped like circular blanks and devices for derolling and unwrapping said blanks. In this combination, these devices facilitate an obliteration of workpieces that are shaped like circular blanks without almost any human intervention. The invention also relates to preferred configurations of these devices.
Abstract:
Glass fibre is in the form of rigid monofilament fibres, at least 30 % of the monofilament fibres having a diameter greater than about 30 mu m and/or at least 50 % of the monofilament fibres having an aspect ratio of less than 30. The monofilament fibres generally have lengths in the range 0.1 to 6.5 mm. Such rigid monofilament glass fibres may be produced from longer lengths of glass fibre by a novel size reduction technique that involves feeding glass fibre to apparatus comprising a rotating shaft rigidly carrying external protruberances lacking sharp edges, with an associated screen, that processes the fibre into short lengths of individual monofilament fibres, creating minimal fines. The feed material glass fibre may be from any suitable source. One economically attractive and highly suitable source is downchute waste residue resulting from glass fibre production. At present this material is treated as waste which is difficult and costly to dispose of. By converting this waste residue to short lengths of monofilament fibre, what would otherwise be difficult to handle waste material is converted into an easily manageable form that has many uses, e.g. in plastics composites, polymeric concretes and cements and in coating materials.
