摘要： A roller crusher having two generally parallel rollers arranged to rotate in opposite directions, towards each other, and separated by a gap, where each roller has two ends. The roller crusher includes a flange attached to at least one of the ends of one of the rollers and a movement blocking arrangement structured and arranged to limit the gap between the rollers to a minimum gap of at least 45 mm. The roller crusher further includes at least one scraper positioned at an end of the roller with a flange. The scraper is positioned such that a minimum roller surface distance between each scraping surface of the at least one scraper and the outer surface of the roller is at least 70% of the minimum gap. A method for arrangement of a roller crusher is also provided.

摘要： A grinding roll including a roll body having a cylindrical outer surface extending axially between a pair of opposite ends, and a side groove formed at each end of the roll body. The side groove includes a support shoulder recessed from the outer surface and/or from surfaces of the opposite ends of the roll body. The grinding roll includes an edge ring including a plurality of spaced receiving cavities, and a plurality of wear members each being received and retained in at least one of the receiving cavities. The wear members are positioned along the edge ring to define an edge of the grinding roll, and the edge ring is received within each side groove. The wear members are arranged to provide a wear protecting surface which is angled in relation to the outer surface of the roll body to prevent excessive build-up of material on the grinding roll.

摘要： A miter saw has a base having a detent notch, a table rotatably connectable to the base, a pivoting assembly connected to the table, and a saw assembly supported by the pivoting assembly. The saw assembly has a blade movable downwardly for a cutting operation. A locking mechanism is disposed on the table. The locking mechanism is movable between an unlocked position and a locked position for selectively unlocking and locking the table for rotational movement relative to the base about the miter axis. The locking mechanism has a lock lever rotatably connected to the table. The lock lever has a handle for moving locking mechanism between the locked and unlocked positions. The saw also has a miter detent assembly for selectively engaging and disengaging the detent notch.

摘要： An infeed protection device for a rolling mill, comprising a housing and a plurality of parallel rotating rollers. A product infeed is formed by two of the rollers which rotate about rotational axes arranged parallel with one another and arranged at an adjustable roller space with respect to one another. The infeed protection device comprises a profile which is arranged parallel with the rollers forming the product infeed and extends over the length of the product infeed. In an infeed direction of the rotating rollers, the profile is upstream of the rollers forming the product infeed. At least one vertical through-opening is formed in the profile. A space is formed between the profile and the rollers. The infeed protection device further comprises a holder for fastening the infeed protection device to the housing of the rolling mill.

摘要： A grinding roll including a roll body having a cylindrical outer surface extending axially between a first end and a second end and a flange attached to at least one of the first and second ends. The flange includes an outer edge that extends radially past the cylindrical outer surface of the roll body. A first surface of the flange forms a perpendicular continuing surface with the cylindrical outer surface of the roll body. A second surface of the flange forms a continuation of one of the first and second ends of the roll body. The flange includes wear protection liner elements on the first surface. The first surface of the flange includes at least one lower part adjacent the cylindrical outer surface of the roll body and at least one upper part adjacent the outer edge of the flange. The lower part includes a first type of wear protection liner elements and the upper part includes a second type of wear protection liner elements. The average covering area of the second type of wear protection liner elements is larger than that of the first type of wear protection liner elements.

摘要： An apparatus for decompressing/pulverizing and fluffing up bales of compressed thermal insulation includes grinding wheel and a grinding die adjacent thereto thereby forming a gap therebetween. The grinding wheel is constructed with a plurality of plane members cut from flat steel material and stacked longitudinally about a rotatable shaft. The plane members each include a perimeter surface which together form the grinding wheel mantle surface and protrusions thereon. Coupling rods extend through aligned holes in the stacked plane members and retain the plane members in their stacked positions. The grinding die is constructed with a plurality of die plates cut from flat steel material and which are stacked longitudinally. The die plates each include an abutment surface which together form the grinding die surface and protrusions thereon. Coupling rods similarly extend through aligned holes in the stacked die plates and retain the die plates in their stacked positions.

摘要： Processes and systems for commercial scale milling of wheat are disclosed. Processes include multiple tempering steps of controlled duration and cubing of the wheat kernel between two tempering steps. The cubing between the tempering breaks the kernels, or stresses the kernels, in a manner that enables a high degree of separation of the bran and endosperm early in the flour production process. An embodiment includes tempering for a first period between hour and 2 hours, cubing in a roll crusher with longitudinal corrugations on one roll and circumferential corrugations on a second roll, removing fines from the cubed kernels, and further tempering of the cubed kernels for a period between hour and 2 hours.

摘要： Crop processing rolls for operative use in forage harvesters are formed from independent segments having a plurality of first grooves that are oriented in a parallel manner with second smaller grooves intersecting the ridges to form discrete teeth from the ridges. The ridges can be formed vertically, horizontally or in a spiraled pattern with the smaller second grooves oriented into a spiraled pattern to form the discrete teeth. Crop processing roll segments can be formed in this manner and assembled into full processing rolls with the spiraled second grooves being oriented in opposing directions from adjacent segments. The number of segments can vary from two to eight individual segments with the second grooves breaking ridges into discrete teeth on adjacent segments forming a chevron pattern at intersecting positions along the longitudinal length of the processing roll.
