Definitions

  • This invention relates to a roller mill for cereals.
  • Roller mills for cereals comprising one or, more frequently, two pairs of counter-rotating grinding rollers, one of which is fixed relative to the machine shoulders and the other of which can be moved relative to the fixed roller and is provided with mechanical members for adjusting the parallelism between it and the fixed roller and for controlling its approach to and withdrawal from this latter.
  • the speed of rotation of the fixed roller is generally greater than that of the movable roller, the fixed roller wears more rapidly and has to be replaced more frequently.
  • the fixed roller to be positioned on the outside and the movable roller on the inside.
  • Both the fixed roller and the movable roller are gnerally provided with bearings supported by supports mounted on the machine shoulders.
  • the supports for the fixed roller are fixed to the machine shoulders, whereas the supports for the movable rollers are pivoted on pins which are eccentrically pivoted to said shoulders.
  • An object of the invention is to replace the grinding rollers in a considerably more simple, comfortable and rapid manner.
  • a further object of the invention is to effect this replacement without the need to use special equipment, but simply by using a truck slidable along the floor of the grinding hall.
  • Figure 1 is a schematic side view of a roller mill according to the invention of symmetrical type with the right half in operation and the left half undergoing grinding roller replacement;
  • Figure 2 is a detailed side view to an enlarged scale showing the supports for the grinding rollers and their adjustment linkage; and Figure 3 is a front view thereof of Figure 2.
  • the roller mill according to the invention is shown in its symmetrical form with two pairs of grinding rollers and comprises a structure formed from two cast iron shoulders 4 joined together by two front walls 6, plus an upper internal structure 2.
  • Each shoulder 4 forms with the structure 2 a horizontal slot 8, open towards the front edge of the shoulder, for passage of the journals 10 of the .two grinding rollers 12 and 14 of each pair.
  • each roller 12 In proximity to the shoulders 4 the two journals of each roller 12, 14 are supported by bearings 16 housed in corresponding open supports 18 closed by front covers 20..
  • Each front cover 20 is fixed to the relative support 18 by screws 22, and each support 18 is pivoted lowerly to the relative shoulder 4 on a pin 24, 24' projecting outwards therefrom, and is also provided with an upper appendix 26 through which a tie rod 28 passes to connect the supports 18 for the two rollers 12, 14 together when in the operating state.
  • the tie rod 28 which is fixed at its centre to the fixed structure of the roller mill, has its two threaded ends engaged by nuts 30, 30', of which the first 30 is directly in contact with the support 18 for the fixed roller 12, whereas the second 30' adheres to a series of cup springs 32 interposed between it and the appendix 26 of the support 18 for the movable roller 14.
  • the system connecting together the supports for the two roller 12 and 14 also comprises conventional swinging and centering members, which are not described as they are of known type.
  • each support 18 for ' the fixed roller is pivoted to the corresponding shoulder 4 there is pivoted the end of a fork lever 36, which is pivoted at its centre to a pin 38 fixed to the shoulder 4 and is pivoted at its other end to a pneumatic cylinder 40.
  • the rod 42 of the piston housed in the cylinder 40 is pivoted to the end of a further lever 44 fixed to the pin 24' which is eccentrically connected to the corresponding shoulder 4.
  • a bush 46 To the lever 44 there is pivoted a bush 46, to which threaded rod 48 is axially fixed but is free to rotate within said bush 46.
  • the threaded rod 48 is engaged in the bush 34 and is provided at its outer end with an operating handwheel 50.
  • the operation of the machine according to the invention is as follows: under normal operating conditions the two grinding rollers 12 and 14 are arranged parallel to each other at the required distance apart for the specific grinding to be undertaken, and are maintained elastically in that position by the opposing effect of the cup springs 32 and other springs 52 interposed between the rollers.
  • roller Having released the two rollers 12, 14 from their supports the roller can be rolled via their journals along the lower edge of the slots 8, until they reach a truck (not shown) which in the meantime has been positioned in front of the roller mill in prolongation of the lower edge of the slots.
  • rollers 12 and 14 can hence be removed from . the grinding hall without requiring any lifting equipment.
  • roller mill according to the invention is particularly advantageous, in that it enables the grinding rollers to be replaced in a very simple and rapid .manner, which inter alia does not require any special equipment for lifting the rollers.

Abstract

Moulin à cylindres pour céréales, possédant une structure dotée d'une paire de paliers (4) sur lesquels sont montés des supports (18) pour au moins une paire de cylindres broyeurs (12, 14) s'étendant parallèlement entre l'un des paliers et l'autre, et étant munis de tourillons (10) traversant lesdits paliers (4) par l'intermédiaire de fentes sensiblement horizontales (8). Les deux supports (18) des deux cylindres (12, 14) sont montés pivotants sur les paliers (4) de la machine au-dessous de l'axe de broyage, reliés l'un à l'autre au-dessus dudit axe lorsqu'ils sont en état de marche, et constitués d'au moins deux pièces démontables (18, 20) qui, une fois démontées, permettent auxdits supports de se replier entièrement vers le bas autour de l'axe selon lequel ils sont montés pivotants sur les paliers, les cylindres pouvant dès lors être remplacés, et les tourillons (10) des cylindres pouvant rouler le long du bord inférieur desdites fentes (8) afin de transférer lesdits cylindres vers l'extérieur du moulin à cylindres.
