Definitions

  • the present invention is a solution for a machine frame for two-roll roller presses for receiving the radial grinding forces.
  • Roller presses are machines for comminution with usually two rolls, which are arranged in a machine frame. For the comminution, the particles are drawn into a nip, pressed together by the high pressure exerted by the rollers and crush each other. Roller presses are also referred to as roller mills or presses and are used in cement production and mining.
  • the machine frame must absorb the high radial forces as well as the occurring axial forces. In this case, torsions in the machine frame are to be avoided, as these lead to a malposition of the rolls and thus in an inhomogeneous pressure distribution with concomitant deterioration of the crushing result.
  • the rollers are guided with their bearings and held in position in the axial direction, while allowing a misalignment and the possibility of horizontal movement of the rollers or their storage in the frame.
  • the Losrolle has a much greater freedom of movement than the fixed role due to a support by hydraulic cylinders
  • the machine frames of the two-roll roller presses are designed as a system of at least four individual frames.
  • This includes at least two radial frames and at least one axial frame.
  • the terms axial frames and radial frames mean that the axial frames absorb the axial forces of the rollers and the radial frames absorb the radial forces of the rollers. Consequently, the radial frames are aligned at 90 ° to the axis of rotation of the rolls and the axial frames in the direction of the axes of rotation of the rolls.
  • the single frame are rectangular, so a flat structure with four carrier-like frame elements. In the assembled state, the planes formed by the single frame are connected at right angles to each other across each other and thus form a cuboid.
  • the single frames have long sides and short sides, the longitudinal sides are arranged horizontally in the assembled state and the short sides vertically.
  • the longitudinal sides are referred to as straps, based on the installation as upper and lower straps.
  • the DE 10 2010 015 374 A1 to provide U-shaped side frames which are closed by vertical frame sections. These frame sections close the U-shape and are removable for disassembly of the rollers.
  • the forces generated in the roller system must be transferred to the frame.
  • the DE 10 2010 015 374 A1 proposes not to connect the frame sections firmly with the legs of the U-shaped side frame. This is intended to enable the frame sections to transfer the forces occurring to the machine frame via hammerhead-shaped closure elements provided for this purpose.
  • a disadvantage of the said construction is that the frame sections must absorb large forces.
  • connections between the end piece and the tension belt consist of several shear bolt screw connections. These connections require a complex component production, which will not be solved after completion of the roller press.
  • the vertical frame end pieces also called vertical beams, consist of two parallel, vertically arranged, spar-like side parts, which are connected to each other at the upper end by the rotational axis of a rotary joint.
  • the swivel joint is preferably fastened by means of an axis of rotation with slide bearing and locknuts.
  • the axis of rotation carries a suspension joint between the two spar-like side parts.
  • the suspension joint has centrally a ball (lower link ball).
  • a lower link with a lower link hook (lower link quick coupler) is attached to the axial frame.
  • the handlebar geometry provides the partial conversion of the vertical weight force into a horizontal force component.
  • the lower link catch hook attached to the axial frame, a complementary to the lower link ball recess on. In this recess, engages, while maintaining the degrees of freedom of movement, the lower link ball on the suspension joint of the vertical beams.
  • the lower end of the vertical frame end pieces is inserted into cavities formed of the lower axial frame, a closure member and the lower straps.
  • the side parts at its lower end preferably on the side facing away from the pivot side, preferably insertion surfaces.
  • These plug-in surfaces facilitate the insertion of the side parts in the cavities. They are preferably conically shaped and have in a preferred development sliding coatings (eg. Teflon) on.
  • the vertical bars stuck in the lower part with their corresponding formations in adjustable plug-in surfaces for example, formed of comb-shaped arranged on an axis disc pairs that prevent rotation of the vertical bars around the vertical. This improves the reliability against tilting the spars from the horizontal planes.
  • the Holminnen vom remain so in operation parallel to the radial force plane (longitudinal direction of the straps)
  • the lower and upper straps are preferably designed as parallel running over double belts, which are connected at the head ends with special hammerhead-like welded structures - the head joints.
  • the straps pass between the two parallel side panels of the vertical frame sections.
  • the vertical beams are supported in the direction of the radial force (radial force acts offset by 90 ° to the roller axes) on the welded head joints of the double straps.
  • the straps connected by means of the preferably welded head connections have an elastic damping element.
  • the damping element of the double straps is biased by the amount (path) resulting from the elongation resulting from the operating force.
  • the biased by a defined path elastic support of the straps in operation at nominal force is almost relieved, i. relaxed.
  • the box-shaped frame elements of the belt system are preferably designed as parallel components, between which run the straps. Due to the screwed head parts with the required adjustment gap, the box frame is closed around the double straps, into which the vertical frame sections (vertical bars) are inserted. By the screwed head parts at the two ends of the associated box frame, preferably made of steel profiles, the elastic damping elements of the belt system are biased. When radial forces occur, the vertical beams pick them up and forward them to the double belts via the welded head connections. These are stretched, whereby the expansion movement of the straps is absorbed in the elastic damping elements.
  • the elastic damping elements are biased by the amount, which results arithmetically from the operation at nominal force for the long straps. As a result, the elastic damping elements are almost relieved in the operating condition.
  • the bias of the elastic damping elements in the direction of the radial force is created by a defined setting gap between the box frame and top plate by tightening the mounting screws of the top plates is zero. This adjustment gap can be adjusted by adding or removing spacer plates.
