Abstract:
The method and assembly accommodate parallel processing of a plurality of materials such as catalysts simultaneously through use of interactive modules for sizing of material particles to predetermined substantially identical size, for collecting a substantially identical dose of each material, for feeding the dose of each material into a reactor vessel, and for maintaining integrity of the modules, or units thereof, intact during interaction between structures so no particulate material is lost during necessary processing for ultimate efficacy testing in a least compromised manner.
Abstract:
The invention provides a crusher which can produce uniform finely pulverised material without having to increase the speed of the rotor, and which has a good rate of productivity. The crusher comprises crushing vanes 3 having extensions 35 formed protruding radially from the outer surface of the rotor 1 and extending below a raw material drop point A of a dead-bed 4, and an annular wall 5 similarly positioned below the raw material drop point A of the dead-bed 4, on an inner rim of a lower plate 22 of the crushing chamber 2, and pulverizing is effected by the material 7 which rebounds and falls from the dead-bed 4, striking the extensions 35 of the crushing vanes 3.

A method and a device in which food waste is conveyed to a storage tank from an inlet using a difference in air pressure between the inlet and the storage tank.
Abstract:
The present invention is directed to a tire comminution apparatus that is of simple construction and that can be operated without excessive maintenance. According to the present invention, a vehicle tire of any size or composition can be comminuted with essentially the same comminution apparatus. The comminution apparatus includes a freely moving lance with a nozzle for transforming a liquid into a high velocity liquid jet. The lance is positioned and controlled such that the liquid jet impacts the tire thereby separating it into its component parts. The comminution apparatus may be computer controlled.
Abstract:
In a rotary mineral crusher a method of either localising the wear on a weir tip (1) in the crusher and/or focusing the output of the rotor (7) into its interaction chamber and/or reducing mineral erosion of the exterior of the rotor (7) by mineral piece particles energised by the output from the rotor (7). The rotary mineral crusher is of a kind having a rotor (7) into which the mineral pieces to be reduced in size, that is crushed, are fed from above and least substantially axially over the axis of rotation of the rotor (7) to thereafter migrate on an acceleration locus or loci of migration there retained bed or retained beds of mineral pieces from the rotor (7) substantially radially of the rotor (7) into the surrounding interaction chamber capable of retaining the lining of the mineral material. The method comprises or includes retaining the, or each, rotor (7) retained bed of mineral pieces with weir-like means defining a sacrificial edge or weir tip (1) over at least substantially the traverse extend of a migration locus at each edge. The sacrificial edge is of the form which allows an enhanced flow of mineral pieces over a preferred region of the sacrificial edge without reliance for such enhanced outflow (2), on a symmetric “V” or “U” or scallop. The means to retain the lining of mineral pieces of the surrounding interaction chamber is also configured so as to provide a preference for interaction of mineral pieces in a zone of the surrounding chamber adequately lined with such mineral pieces. Optionally, there is also provided shielding means (5, 6) to at least substantially confine the mineral pieces of the interaction zone from the rotor (7), save over the enhanced outflow (2) focus, and thereof at least towards the retained lining of the mineral pieces of the interaction chamber.
Abstract:
A shredder including a frame, a housing with a housing opening mounted to the frame, and a cutting blade mounted within the housing for use in shredding associated lawn debris is provided. The shredder also includes an engine mounted to the frame for use in driving the cutting blade and a hopper assembly for use in directing the associated lawn debris into the housing opening and to the cutting blade. The hopper assembly includes a chute having a first end pivotably connected to the housing and having a chute opening for receiving the associated lawn debris. The chute opening communicates with the housing opening. The chute can be positioned into first and second positions with respect to the housing. The hopper assembly also includes a flap for automatically covering at least a portion of the chute opening when the chute is placed in the first position and for automatically uncovering the opening when the chute is placed in the second position. A flap bail pivotably connected to the chute is used to hold the flap against an inner surface of the chute thereby uncovering the chute opening. The flap bail is adjusted as the chute is adjusted by an adjustment mechanism. The adjustment mechanism includes a control rod having a first end and a second end that is pivotably connected to the housing. The adjustment mechanism also includes an arm bracket having a first end fixedly connected to the first end of the flap bail and a second end pivotably connected to the first end of the control rod.
Abstract:
A synchrocrusher for making a material collide in which the rotor is designed with a symmetric configuration. The rotor contains equal numbers of respectively forward and backward directed guide members and co-rotating impact members which are arranged, as synchronized pairs, in each direction of rotation. The pairs are circumferentially disposed uniformly at equal angural distances around the axis of rotation with the forward and backward directed configurations mirror imaged 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 allows for many interesting synchrorotor configurations.
Abstract:
The invention relates to improvements to rock crushers, and in particular rotary impact rock crushers. The crushing chamber may be angled to achieve the desired rock product. Also disclosed is an anvil for use in crusher whereby the anvil position adjustable. The invention enables the operator to dial up a particular rock product specification by adjusting the angle of the crushing chamber and/or the position of the anvil. The adjustments may be made without ceasing the operation of the machine. Improved control over fracture mechanisms within the crushing chamber and as a consequence the rock product, are achievable with the present invention.
Abstract:
A tearing mill for comminuting fruits is equipped with a rotatably supported plate having tearing elements And with a stuffing device with a feed screw for delivering the fruits to the plate. A gap of adjustable width exists between the stuffing device and the plate. By means of an independent control of the gap and the rotational speed of the feed screw and plate, a mash structure of the comminuted fruits is achieved which is well adapted to the type of fruits and to subsequent processing of the mash.
Abstract:
The invention relates to a method and an apparatus for performing the method by means of which accumulations of a bunkered powdery or granular bulk material which are compacted in a silo or in the conical section (15) of a container (10) are comminuted for the discharge. A swivelling member (25) is arranged above the outlet opening (18′) in the conical section (15), and on the inner wall (16′) of the conical section (15) and on said swivelling member at least one, but preferably a plurality of elongated extraction elements (14) are arranged which are oriented in the direction of the conical wall (16) of the conical section (15) and are in engagement with the compacted accumulation of the filled bulk material in such a way that during a swivelling movement of the swivelling member (25) which is oriented about the vertical axis (Y) of the container the accumulation is comminuted for the discharge as a result of a frictional, scratching or excavating action. The swivelling member (25) is preferably swivellably driven back and forth about the vertical axis (Y) by a drive unit (70).
