    A method and apparatus for blending particulate materials in which a plurality of blending chambers receive, by a series of instalments, pre-mixed ingredients so as to ensure that each blending chamber contains an average sampie. The blending chambers are then discharged in sequence to provide an output as a series of sub-batches which each comprise the predetermined proportions of ingredients.

    The invention relates to a mixing technique and may find application in the processes of continuous compounding rubber and other elastomers or plastics.
    The purpose of the invention is to increase the mixing efficiency due to a decrease in the UT effect of segregation.
    Fig. 1 schematically shows a device for mixing powdered materials, a partial section; FIG. 2 is a schematic depiction of the valve body mechanism in the open State; FIG. 3 is the same in the closed state; FIG. 4 is a schematic depiction of the lower valve mechanism.
    ; Device for squeezing contains a means for the supply of ingredients, made in the form of a nutrient gutter I, mounted on the drive mechanism of a-ifie 2, driven by the ijiTBOM of the vertical shaft 3 from the motor (not shown). Under the chute is placed aaOor mixing chambers 4, made in the form of pipes made of flexible material | (rubber, plastics). The pipes are open at the top and installed vertically with the help of three rings 1; 5 5 of the disks; Number of pipes 48. On the top disk 5 there is a conical key 8, in which the branch pipe 9 is installed. The inserts are inserted. Each lower co | 1ts pipe 10 is equipped with a discharge
    By means (Fig. 4) in the form of a clamp of the 1st valves 11 with levers 12, Between the levers, the coupling link 13 is placed, the unloading means is driven in |; the action with the help of the rollers 14, the interacting - cam mechanism, and the shape of a movable ring 15. In the ring there is a hole 16 and which rolls down the roller 14.
    The mixing device is provided with an additional discharge means 17 installed in the middle part of the mixing chambers. It is also made (Figures 2 and 3) in the form of clamping valves 18 with levers 19 and a clutch link 20. The cam mechanism 21 is in the form of a ring rotating under the action of a pneumatic actuator (not shown). The fixed rollers 22 interact with a slope 23 of the ring raising or lowering it. The unloading means has rollers 24,

    modulating with cam mechanism.
    The mixing chambers are enclosed in a cylindrical casing 25 to prevent dust from being carried out from the pipes and equipped with a conical dust cap, the lower part of which is attached to an annular disk 5, hermetically protecting the inner surface of the apparatus from dust. The annular disks 5-7 form a frame for accommodating pipes. The frame is installed with the possibility of rotation around the vertical axis. The frame is rotated by means of a mechanism 26 including a pneumatic piston and a mechanism comprising a pawl 27, which is engaged in engagement with the teeth of the ratchet mechanism 28.
    The housing has a base 29 with an outlet channel 30. For ease of design and to ensure compactness, as well as to facilitate the manufacture of simple pipe clamping valves, it is desirable to install them so that they have an elongated shape in horizontal section and that the large axis of the section is radial.
    The device works as follows.
    At the beginning of operation, the apparatus is in such a position that all the valves 11 are closed and all the yutanas 18 are open. The mixtures of rubber and compounding ingredients are prepared in portions of 100 kg each and five of these 100 kg portions are introduced into the mixing chambers by means of nutrient trough 1 with its continuous rotation at a speed of 15 rpm. A feed of 100 kg to the blender is carried out for about one minute. During this time, the chute performs approximately 15 circular rotations around the axis and each tube will receive 15 portions of mixed ingredients from each 100-kilogram portion. The row of valves 18 is then closed in such a way that the pipes are divided into upper and lower parts, with the lower parts already filled and ready for discharge, while the upper parts are empty and ready to receive an additional five 100-kilogram portions of equipment mixing. After toh oh how the lower parts of the tubes are “completely filled.
    the equipment is ready, start unloading into the mixer (continuous kneader). To this end, the frame rotates with the action of the mechanism 26 with a constant rotation, the supply of each pipe alternately to the outlet channel 30.
    - Simultaneously with the unloading of the lower sections of the pipes, the upper sections are loaded, when the lower parts of all the pipes are empty, the lower valves are closed. Valves 18 are then actuated to discharge the contents of the tops of the tubes to the respective lower portions so that the mixing operation can continue almost without interruption. The valves 18 then close and the upper parts begin to fill again.
    The operation of the lower valve mechanism is realized in this way.
    By turning the pipes when the TO pipe is set above. the outlet channel 30, its valve 11 is opened by means of a roller 14, which is lowered into the hole 16 in the ring 15. As the frame rotates further, the tube moves, the associated rod 4 passes along the cam surface, closing the valves.
    When the upper valve mechanism is operating, the rotation of the ring 21 from the position shown in FIG. 2 in polo
