Abstract: In a method for manufacturing fibril cellulose, cellulose based fibre raw material is processed mechanically in a refining gap for separating fibrils. The fibres to be refined are subjected to the action of a surface roughness Ra provided by grits elevated from a refining surface delimiting the refining gap, said surface roughness being lower than 3 ?m, advantageously lower than 2 ?m. The refining surface is formed by spraying grits and binder onto a substrate.

Abstract: A jaw crusher has a substantially fixed jaw and an opposed movable jaw. A pair of opposed side walls extend from either side of the jaws to define a crushing zone. Each side wall includes one or a plurality of side liners configured to protect the side walls. A security or capture projection extends from the side wall to one side and adjacent to each side liner and prevents the side liner from falling downward from the crushing zone in the event of dislodgement from its mounting position during use.

Abstract: The invention broadly relates to methods of fragmenting seed by use of mechanical devices such as crushing pins or other crushing devices with a preconditioned hard seed. Methods of preconditioning the seeds to soften the seed for more effective fragmentation which are adapted to enhance extracted DNA yields and/or DNA quality are shown. Extracted DNA yield from alkali-soaked seeds can be significantly increased by adding an osmoticum to a seed-softening alkali soaking solution used for pretreatment of the seeds prior to crushing them. The osmoticum inhibits and reduces liquid uptake by the seeds, but the seeds are weakened enough to be crushed with steel beads, without requiring the use of crushing pins or other crushing devices.

Abstract: The present invention relates to a crushing system with two rotating disk sections which allows applying high pressures without the problem of raw material rejection and with a reduced number of crushing cycles, thus shortening the crushing time. Pressure is gradually distributed between the two similar rotating disk sections which are arranged face to face and connected to non-aligned shafts, such that the lower sides of the disk sections remain always joined. The disk section mounting assembly is independent and has different features, forming a fixed part and a movable part for adjusting the vegetable mass being compacted. This crushing system has structural features that allow different uses (in isolation, in tandem or in combination), and the serial combination thereof in appropriate industrial infrastructures or in harvesters of standing crops, such as sugar cane.

The frame has an opening forming an access way to the shear member slide bearing. The main blade and the counter blade cooperate to chop the scrap material when the shear member is moved from a first position to a second position. The shear member slide bearing is removable from inside the frame through the opening without removal of the shear member from the frame.

Abstract: There is described a crushing plant and a method for controlling the same. The crushing plant includes a crusher (1) and a feeding arrangement (3), and is driven by a diesel engine (13). A load value related to the diesel engine is retrieved e.g. by means of a J1939 interface. If the retrieved value exceeds a predetermined threshold value, the control loop of the feeding arrangement (3) is altered. Thereby it can be avoided that the diesel engine (13) stalls, such that continuous operation of the crushing plant may be ensured.

Abstract: The present invention regulates the delivery of feedstock to the fragmentation zone in a gravity-fed comminuting machine and reduces the ejection of feed materials by means of a rotating cylinder located at an offset position above the rotor. Rotationally mounted on an axis parallel to and above, but offset from, the axis of the rotor, this cylinder serves primarily as a striking surface, or anvil. The continual rotation of the anvil, in the opposite rotational direction as the rotor and with much slower rotational speed, assists in agitating the feed material, alleviating the problems of feed chute obstructions and feed aggregation. The cylinder forces the feed materials into contact with the rotor teeth through continuous rotation and provides a novel tooth design to improve efficacy and reduce wear.

An apparatus is provided for applying pressure to the wall for moving the wall in the first direction. At least one pressure sensor associated with the apparatus for applying the pressure is provided. When a predetermined pressure level is reached, the wall ceases moving in the first direction and begins moving in the second direction.
