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： A milling roll of a roll mill may have a roll main body and an edge element that is attached to an end region of a roll end of the milling roll and extends in a radial direction beyond a surface of the roll main body. The edge element comprises a base flange and a spacer element that is attached thereto. Wear protection elements can be attached to the spacer element. Furthermore, a roll mill may have a first milling roll and a second milling roll that are arranged opposite one another and can be driven in opposite directions. A milling gap is disposed between the milling rolls, and an edge element on one of the milling rolls may extend over the milling gap and at least partially cover an end side of the opposite milling roll.

摘要： A roller press machine capable of applying an electric field includes a base, a frame, press rollers, a distance adjusting device, a speed adjusting device, a voltage applying device, a feeding baffle, and a discharging device. The press roller has a roller surface made of conductive material, and an electric field is created when a charge is applied to the press roller. In the roller press, an alternating or direct current electric field is applied between the press rollers to create an electrochemical action, such that particles or a solution in a system is induced to undergo a physical or chemical change, thereby enhancing interaction therebetween, and accordingly increasing grinding and dispersion efficiency of a solid-liquid dispersion system.

摘要： The invention relates to a test arrangement for testing breakage and mechanical properties of rock particles. Test arrangement comprises a support (1, 2) and two counter-rotatable crushing rolls (3, 3′) supported on the support (1, 2) and a drive arrangement (M1, M2) for rotating the crushing rolls (3, 3′). Crushing rolls (3, 3) are facing each other and defining therebetween an input gap (G) for the rock particles, said rolls being arranged to crush rock particles (RP) to smaller daughter particles (DP). Test arrangement comprises a force measurement arrangement (7, 7) for determining the compressive strength of rock particles (RP). Force measurement arrangement (7, 7′) being coupled to a processor (PR) comprised by the test arrangement. The processor (PR) being arranged to calculate the breakage force applied to each rock particle (RP) over time. The test arrangement (TA) further comprises an energy measurement arrangement (5, 5′) for measuring information relating to energy applied to each rock particle (RP), said energy measurement arrangement (5, 5′) being coupled to said processor (PR), said processor (PR) being arranged to calculate energy applied to each rock particle (PR).

摘要： The present invention relates to a machine frame for a roll crusher that has two side walls and two end walls, where the mentioned end walls accommodate the storage of the rolls. The end walls are split horizontally in the area of the mounting of the rollers, and vertically between the mountings of the upper part. One advantage is that to remove a roller, removal of the respective upper end wall is sufficient. In a preferred embodiment of the invention, the adjacent upper parts of the end walls do not touch. An advantage of this is that tilting of the end wall upper parts among each other or in contact with the side walls is prevented during removal. Furthermore, the gap resulting from the distance between the front wall upper parts in the preferred embodiment would be sealed, with the advantage that no material and dust can exit.

摘要： A double roll crusher is provided for mined oil sands feed, even in the winter season. Each roll has a driveline driven by a high efficiency motor controlled by a variable frequency drive (VFD). Through removal of the prior, yet ubiquitous fluid coupling and related failure-prone components, a shorter, streamlined, lower inertia driveline results. The VFDs and a system controller adapt to the processing of difficult oil sand feed, anticipating high current events, adjusting roll speed on-the-fly, adjusting feeder rate or both to minimizing the high cost of process interruptions. Maximum startup torque and on-the-fly modification of roll and feeder speeds is provided to manage feed, environment and process variations and in instances of a stall, immediate recovery therefrom for reduced downtime, reduced wear and increased efficiency.
