摘要： A roller mill (1) including a housing (2) having a milling-material inlet (3), at least one milling-material outlet (4), and at least two cambered rollers (5, 5′) which are each arranged in the housing (2) so as to be rotatable about a roller axis (6). At least one roller (5) is assigned a scraper (7). The scraper (7) has a blade (8) for scraping milling material from a roller surface (9) with a scraper edge (10) which extends over an entire length (L) of the blade (8), and comprises a holder (11) with a receiving region (12). The holder is arranged in the housing (2) so as to be tiltable about an axis (13) parallel to the roller axis. An elastic bearing (14) is arranged between the blade (8) and the receiving region (12).

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： The invention relates to a process for producing superabsorbent polymer particles, comprising polymerization of a monomer solution, drying the resulting polymer gel and grinding the dried polymer gel with a roll mill, wherein the rolls of the roll mill are cleaned by reducing the feed rate to the roll mill, and if the deflection and/or the power consumption increases above a setpoint, operating the roll mill with reduced feed, and increasing the feed rate to the roll mill.

摘要： A fiber powder having a 50% particle diameter (d50) of 6 to 60 μm, characterized in that the fiber powder has a maximum particle diameter (d100) of 1,000 μm or less. It is preferred that a value ((d10·d90)/d100) obtained by dividing by the maximum particle diameter (d100) a value which is obtained by multiplying a 10% particle diameter (d10) by a 90% particle diameter (d90) is 0.3 to 5.0, that the fiber powder has an extractable component content of 0.2 to 3.0% by weight based on the fiber weight, and that the fiber powder has a water content of 0.2 to 50% by weight. Further, it is preferred that the fiber powder is an organic material, or comprises a thermoplastic resin, and that the thermoplastic resin is a polyester resin or a polyamide resin.

摘要： A distribution metering device (I) for a roller mill which includes a housing (2) with at least one grinding stock inlet (3), at least one grinding stock outlet (4), and a feed roll (5) which is arranged in the housing (2) for metering grinding stock into a grinding gap of the roller mill through the grinding stock outlet (4). The feed roll is rotatable about a feed roll axis (SA). A conveyor shaft (6) is arranged in the housing (2) for distributing grinding stock along the feed roll (5). The conveyor shaft is rotatable about a conveyor shaft axis (FA). The conveyor shaft axis (FA) is substantially parallel to the feed roll axis (SA), and a first fill state sensor (7) is arranged in the housing (2) for ascertaining a first grinding stock fill state of the housing (2).

摘要： System and method for controlling the startup sequence of a roller crusher is disclosed. The roller crusher includes two generally parallel rollers that are separated by a gap where the rollers rotate in an opposite direction. During startup, the gap between the rollers is greater than the gap during normal production and a feeding arrangement is run at a speed that is lower than a normal production feed rate. The rollers are rotated at a predetermined speed that is less than the speed during normal production. Other parameters of the system are set such that material is fed over the entire length of the rollers and the no crushing force is exerted during the startup. The method and system of the present disclosure reduces the amount of stress on the rolls, frame and hydraulic system of the roller crusher.
