Abstract: The present invention is generally related to an apparatus having cutter elements for destroying articles such as paper sheets and a mechanism for advancing at least a top sheet from a stack of paper in a tray into the cutter elements for shredding. In one embodiment, the apparatus uses a rotatable feed roller to feed paper atop the stack to the cutter elements. The feed roller moves in an alternating manner between a lowered and raised position to engage and disengage the stack when advancing the paper therethrough. Alternatively, a rotatable cam may be used. In an embodiment, the apparatus uses a rotatable drum or rotatable belt with an internal vacuum to lift paper from the stack and feed into the shredder mechanism.

Abstract: A control mechanism for the feed of a brush chipper is disclosed. A lower feed stop bar, located under a feed table, pivots on a pivot axis located below and toward the brush chipper from the control bar of the lower feed stop bar. The center of gravity of the lower feed stop bar, then, tends to pivot the lower feed stop bar away from the feed disengage position. Hence, nuisance trips due to vibration, impact of brush on the table, etc., are reduced.

Abstract: An absorbent product manufacturing apparatus including a pulp feed mechanism (2) for feeding a pulp sheet along a lower surface of a pulp guide part (2411) and a pulp crushing mechanism (3) for crushing the pulp sheet from the pulp feed mechanism (2). The pulp crushing mechanism (3) crushes the pulp sheet with a first crushing cylinder (312) and a second crushing cylinder (322). The crushing cylinders are disposed so as to be inclined with respect to a direction of feeding the pulp sheet. This reduces the force necessary to draw the pulp sheet in the feeding direction and suppresses an increase in the movement speed of the pulp sheet in crushing a rear end portion of the pulp sheet. As a result, it is possible to increase the amount of crushed pulp to be generated in a unit time and to maintain uniformity in the quality thereof.

Abstract: Methods and systems for controlling a cement finishing mill, and operating the mill at an optimal point, are disclosed. To determine an optimal point of operation, values of mill power and sound are collected and compared to values predicted by a model to determine if the mill is choking. This choking determination is used in one of two processes to determine an optimal point of operation for the mill. In the first process, as long as the mill is not choking, the amount of fresh feed input to the mill is incrementally increased; when choking occurs, the amount of fresh feed is decreased until choking ceases. In the second process, the amount of fresh feed input to the mill is increased and decreased in an oscillating manner over time, to find the amount of feed that results in the mill approaching, but never reaching, a choking state.

Abstract: A wood chipper includes an engine and a cutting assembly. A rotatable feed wheel and a gap-bounding member define therebetween an adjustable gap through which feed material moves toward the cutting assembly. An electronic control unit (ECU) controls force applied to the feed wheel or gap-bounding member toward the feed material in response to an operational condition of the wood chipper. The ECU can maintain or vary the force in any desired manner. One option is to apply the force with a pulsating mechanism in a pulsating manner to enhance the feeding procedure. The pulsating mechanism is in communication with a sensor from which the ECU receives signals typically indicating an operational speed of the cutting assembly or the engine. An ECU logic circuit permits the pulsating force only if the operational speed exceeds a predetermined threshold.

Abstract: A wood chipper or grinder includes counter rotating upper and lower feed drums driven by a hydraulic motor at variable fluid pressure to produce variable torque to the feed drums. Wood debris fed to a gap between the rollers is advanced toward a grinder or chipper to reduce the material. A hydraulic feed control system operates off the variable hydraulic pressure associated with the motor and, in an automatic mode, exerts more or less downward clamping pressure on the upper feed drum with changes in pressure to the motor. The system sets an upper limit on the clamping pressure in the automatic mode which can be overridden manually if necessary to apply greater downward force than that achievable in the automatic mode. The upper feed drum can also be manually raised if necessary.

Abstract: Rope made of cellulose fibers, the polymeric chemical structure of which fibers has not been modified (referred to as “raw” cellulose fibers), are subjected to intense electron beam irradiation insufficient to degrade their chemical structure but sufficient to modify their physical structure so as to allow them to be comminuted into fragments having a length no more than 6.35 mm (0.25?), preferably less than 3.175 mm (0.125?), and preferably 50% by weight of the fibers have a length less than 70 ?m. Such fragments of fibers are found to be particularly susceptible to being micronized in a micronizer into elongated granular fragments smaller than about 20 ?m at an economical production rate in excess of 22.7 Kg/hr (50 lb/hr) which was not possible when the micronizer was fed with naturally occurring fibers.

Abstract: A method for reducing impact damage to a waste fragmentation machine is provided in various embodiments. In general, material that is potentially ungrindable, e.g., unacceptably dense, may be inadvertently allowed to enter into the grinding chamber within the machine where it encounters a high-speed rotor. The high-speed rotor comprises rotor teeth that impact the material to fragment or comminute it to an acceptable size. A vibration detector is placed in proximity with the rotor's bearing(s) and, after taking a daily baseline sample, monitors the fragmentation process. If the vibration level goes beyond an alert upper limit, the operator may be alerted via visual and/or audible annunciation that potentially ungrindable material may be in the grinding or fragmenting chamber. The operator may then examine the waste material and, if necessary, remove any potentially ungrindable material.

Abstract: A method is proposed for improving pulp quality at high production rates on conical disc refiners. It permits a reduction in refining intensity by enabling fibre residence time to increase by increasing consistency, while avoiding the problem of plate plugging normally associated with high discharge consistency. In practice, inlet consistency is increased by the in-feed dilution, flat zone dilution or both, but without allowing the discharge consistency to rise. Instead, the discharge consistency is controlled at a fixed optimum value by the addition of dilution water within the conical zone. The result is that residence time is increased, and refining intensity decreased, by raising the consistency in the inner region of the refining zone, while avoiding the plate plugging caused by excessive consistency in the outer region of the refining zone.
