Definitions

  • the invention relates to an agitator ball mill according to the preamble of Claim 1.
  • DE OS 39 18 092 shows one Agitator ball mill, which is flat and in which a disc-shaped Agitator is surrounded by a horizontally divided housing.
  • the separating element for holding back the grinding media is a flat sieve plate is arranged centrally and below the agitator. With this arrangement of the Separating element, the grinding media together with the regrind are very close to Sieve passed. Due to the suction flow through the sieve and conditionally the grinding force against the Sieve pressed and can clog or even destroy it.
  • the grinding media When flowing through the grinding zones in continuous operation, the The grinding media was dragged along by the grinding stock suspension. The amount of towing force depends on the size and density of the grinding media, on the flow rate and on the viscosity of the suspension. This becomes particularly critical State when throughput and solids concentration are high and when very small grinding media can be used.
  • the grinding media are then with the The regrind is transported to the separation zone and pressed there, which leads to blockages and Wear leads. The grinding media should therefore be before reaching the separation zone separated from the emerging regrind and through a recirculation opening be returned to the grinding zone.
  • the goal is of course a complete recirculation of the grinding media, so that none Separator is needed more.
  • the design the grinding zone and the grinding media return zone are of crucial importance. Ideally, you should ensure that the grinding media before branching of the emerging regrind already have the direction of movement in which they flow through the grinding zone after recirculation. This should not be the Grinding bodies are branched off from the ground material stream, but the ground material suspension from the grinding media flow, because grinding media are much more difficult redirect than the suspension. Because the recirculation of the grinding media taking advantage the centrifugal force should occur, it follows that the flow the grinding zone in this direction, i.e. radially. The invention starts from recognizing that the best separation effect is achieved when the separated one Grist suspension flows in the opposite direction to the grinding media, ie against the centrifugal force radially inwards to the separation zone.
  • the uniform circulation of the grinding media in the mill is affected by the influence gravity is hampered because the bed is in the areas below the mill accumulates.
  • This effect is particularly pronounced in the axis of rotation.
  • This also leads to the fact that the grinding media are heavily compressed when the mill is at a standstill and Restarting requires a significantly higher engine power than for grinding. It is therefore desirable to have a grinding chamber geometry that is as short as possible parallel to gravity.
  • the task is to develop a generic agitator ball mill with a grinding zone and an agitator, which the unhindered circulation of the Allow mill filling with largely exclusion of gravitational influences, enough space for the design of a grinding wheel return system for complete Offer grinding media separation and a cleaning and maintenance-friendly Enable construction.
  • the washer-shaped agitator which can be seen in the figures, is at the bottom of the vertical arranged drive shaft attached and studded with grinding pens.
  • the opposite of the agitator Walls of the housing are also equipped with pins and form together with the agitator two flat, cylindrical cylindrical grinding rooms.
  • the grinding rooms are located above and below the agitator and are through on their outer circumference connected a toroidal transition. This transition can be as further grinding room or be designed as a deflection room.
  • the separator is preferred a slotted sieve with a large cross-sectional area and is hollow inside executed drive shaft arranged coaxially. An inner deflection zone connects the two grinding rooms below the separator. Between the drive shaft and the agitator can be arranged with a grinding media conveyor the grinding media circulation can be influenced.
  • the millbase suspension is on the upper housing part in the area of the drive shaft supplied and when flowing through the annular gap between the shaft and the housing wall equally distributed.
  • the ground material then reaches the interior of the upper one Grinding room, where it homogenizes at still low peripheral speeds and is dispersed.
  • the upper grinding chamber is then in the radial direction flows outside, increasing the peripheral speed and the dwell time.
  • the regrind gets into the lower grinding chamber and flows radially from the outside to the inside. In the The crushing takes place outside the two grinding rooms.
  • To the interior The lower grinding room is followed by a calming zone, into which the entrained grinding media also arrive. In the inner deflection zone the ground material / grinding media mixture in a radially outward flow redirected.
  • a first partial stream of regrind branches off radially inwards and then upwards to Separation zone directed.
  • the separator only serves as a protective device against loss of grinding media under transient operating conditions, e.g. when starting and stopping the mill.
  • the separation zone is in normal operation then free of grinding media, which reduces the risk of wear and clogging reduced to a minimum.
  • the grinding media arrive together with another partial stream of the grinding stock without redirection to the upper grinding zone. Is after the branch of the first partial flow and in front of the interior of the upper grinding chamber, a regrind conveyor provided in the connection there, then by this facility the accelerated further partial flow with the grinding media.
  • a grinding media conveyor supports this mechanism and also reduces the risk of a short-circuit flow of the incoming millbase suspension to the separation zone.
  • the short axial grinding zone areas also cause the Distribute the grinding media evenly when the mill is switched off and hardly any Compression takes place under the influence of gravity. So the grinder can be raised without Torque can be started again, which is the necessary installed drive power significantly lowers.
  • the shape of the agitator and the grinding rooms also has that Advantage that internal surfaces perpendicular to the centrifugal force are minimized, whereby the risk of dead spaces for attachment formation is largely excluded becomes.
  • a rotating deflector wheel can also be installed with which the emerging mill base suspension according to the particle size is classified.
  • the deflector wheel is a complete unit with storage and drive inserted into the mill from below.
  • the deflector wheel either runs freely in the Cavity of the drive shaft of the agitator or is additionally from a close-fitting Surround housing.
  • the millbase suspension comes from the junction after the inner deflection zone into the deflector wheel. Sufficiently fine particles pass through with the liquid the wheel and are through the hollow drilled drive shaft of the classifier and a fines collector.
  • the rejected coarse material mixes with the grinding stock / grinding media flow and is returned to the grinding zone.
