Abstract: The present invention relates to a roller crusher having two generally parallel rotatable rollers separated by a gap, and a feeding arrangement for feeding material to the rollers. The roller crusher includes a base frame and a first and a second roller frame section, each of the first and second roller frames sections being pivotably connected to the base frame and arranged for carrying one of the rollers in bearings arranged at opposed ends of each roller. The roller crusher also includes at least one balancing cylinder extending between one of the roller frame sections and the base frame such that when the at least one balancing cylinder is activated, the interconnected roller frame sections will pivot relative to the base frame, thus adjusting the position of the rollers relative to the base frame.

Abstract: The present invention relates to a roller grinder comprising two rollers, each mounted on a separate shaft, a fixation means, a guide member, and a first and a second end member. A center of the guide member is rotatably attached to the fixation means in a position, which in a horizontal direction is located centrally between said rollers. Each end of the guide member is attached to a first end of the first and second end members, respectively, by means of a joint, such that both the guide member and the first and second end members can rotate around the joint, and the first and second end members, respectively, are rotatably attached at a second end to a respective one of the shafts.

Abstract: The present invention relates to a roller crusher having two generally parallel rotatable rollers separated by a gap, and a feeding arrangement for feeding material to the rollers. The roller crusher further comprising a base frame and a first and a second roller frame section, each of the first and second roller frames sections being pivotably connected to the base frame and arranged for carrying one of the rollers in bearings arranged at opposed ends of each roller. The roller crusher also comprises at least one balancing cylinder extending between one of the roller frame sections and the base frame such that when the at least one balancing cylinder is activated, the interconnected roller frame sections will pivot relative to the base frame, thus adjusting the position of the rollers relative to the base frame.

Abstract: The roller mill according to the invention substantially comprises a rotatable grinding table, at least one grinding roller which is retained rotatably on a pivot lever and which is in rolling engagement with the grinding table, with the pivot lever being arranged for pivoting about a pivot lever axis, and a drive train associated with the grinding roller in order to drive the grinding roller with a fixed motor.

Abstract: An improved two roll sugarcane crushing mill has two roll mill modules in tandem, each has a pair of main crushing rolls having a bottom roll and a top roll. The bottom and top rolls are rotatingly mounted in a pair of main frames and a pair of top beams at the two ends respectively. One end of each of the top beams is pivotally attached near an upper end of the main frames towards a feed side for swinging the top beams along with the top roll. At least one feeder roller is provided with a scraper-cum-deflector with a juice drainer in the close proximity of the main crushing rolls. The feeder rollers are mounted on an auxiliary frame which is mounted on the main frame to adjust the loading the feeder roller in a desired position.

Abstract: A chip destructuring and fissuring machine for destructuring wood chips or the like. The chip destructuring machine includes a support frame and two swing assemblies that provide parallel side-by-side squeeze rollers are swing-mounted on the frame to swing the rollers toward about a swing axis and away from one another between active and inactive positions. A drive motor having a drive shaft with a rotational axis aligned with the swing axis is mounted to the support frame, and drive assemblies couple the drive shaft to the rollers for rotating the rollers in opposite directions at the same rotational speed. Co-acting stops are mounted on the swing assemblies and are positioned to define a spacing between the rollers when they are in the active position for squeezing and destructuring of the chips. A biasing mechanism yieldingly urges the rollers toward one another into the active position.

Abstract: The invention proposes a novel automatic product feed in which an analog signal is formed and at least one other digital signal which is adjustable independently of the analog signal is generated and used for the automatic product feed for supervising the product feed functions by a mechanical probe (8) in the product flow. In this way, all previously known controlling and regulating functions can be realized with a minimum of electronics or at the highest level of computer control as a function of the product feed or for optimizing the grinding conditions, possibly with externally initiated digital signals for various stage adjustments and with the use of very simple automatic component means. The invention further proposes a corresponding method for grinding with a milling roller mill (1).

Abstract: A mill for grinding farinaceous seeds into flour comprises a pair of counterrotating cylinders to which seeds to be ground are fed from a hopper with the aid of a transport roller driven by a variable-speed motor. A sensor inside the hopper measures, e.g. capacitively, the level of a supply of seeds present therein and controls the speed of that motor to vary the feed rate substantially in proportion to the measured level. When the sensor detects a drop of that level below a minimum threshold, it stops the transport roller and causes the cylinders to be separated from each other.

Abstract: A solid waste comminution machine having two pair of cutting wheels, one above the other. The upper pair is mounted on opposed lever arms which are movable relative to the lower wheel pair such that the upper wheel pair can exert leverage on solid waste between wheel members forcing the solid waste material to be worked by the lower wheel pair. The upper wheel pair has peripheral edges adapted for ripping solid waste material between the two wheels, while the lower wheel pair has smooth, hardened, peripheral edges adapted for shearing material forced against the lower wheel pair. The lever arms are pivoted about shafts supporting the lower wheel pair and the inward ends of the lever arms are connected at a joint so that motion of the lever arms can be synchronized.

Abstract: Disclosed is a hay conditioner of basically typical construction in which the improvement lies in adjustable stop means for use in setting and varying the clearance between the upper and lower conditioning rolls. There is provided at each side of the machine a means including a lever arm disposed below a support for the upper roll and pivoted at one end on the adjacent side of the machine frame, the other end being connected to a screw-threaded adjustment link effective to elevate the lever for engagement with the upper roll support and thus to selectively limit downward movement of the upper roll under action of the usual biasing means. Thus, the upper roll is free to move upwardly in response to crops passing between the rolls, but its downward movement is limited to the stopped position selected by the adjustment link. The link extends upwardly to a free end that is easily accessible to receive a force-applying tool.
