    An arrangement for feeding a fine-particle material to be separated to an electrostatic free-fall cutter is formed as a funnel with braking inserts and inclined walls whose edges limit a small elongated rectangular discharge slot, wherein a greater wall is inclined to an opposite vertical wall which has an inclined downwardly directed guiding member, and a wedge-shaped projection with an upper horizontal surface is located at the lower edge of the inclined wall and extends into the discharge slot.

    The invention relates to the separation of finely dispersed triboelectrically charged bulk material in electro-separators of free fall and can be used, for example, to separate the feces of salt.
    The purpose of the invention is to improve the quality of separation of fine material by increasing the degree of uniformity of the flow of bulk material entering the electric separator.
    Figure 1 schematically shows the proposed device; Figure 2 is the same as the embodiment.
    The device consists of side walls 1 and 2, made of electrically insulating material and forming a charging funnel. One of the side walls 2 is located vertically, the other I is obliquely relative to the opposite vertical wall 2. The side walls 1 and 2 in its lower part form a discharge slot 3 of a rectangular shape. Inside the side walls there is a braking element 4, which is made in the form of a bar and is placed on the lower edge of the inclined wall 1. The braking element 4 has a wedge-shaped cross section and a horizontally disposed upper plane.
    The lower edge of the vertical wall 2 extends beyond the lower edge of the inclined wall 1. The vertical wall 2 is provided with at least one inclined guide body 5.
    In the device shown in figure 1, the guide body 5 is completed

    plane. Thanks to this element 4, a movable layer M is formed, from which a constant flow is formed, falling out of slot 3 as a thin layer. A variant of the device containing an additional inclined C 1, additional HO, and HO 5 has a different design is possible. 2 hp f .py, 2 ill.
    in the form of a plane installed on the inner side of the vertical wall 2, the parallel discharge gap 3 in the middle of the height of the vertical 5 wall 2. The guide body 5 forms an acute angle with the lower part of the vertical wall 2, is installed to form a gap in the form of a slot with its free edge and an inclined wall 1.
    The device shown in Fig. 2 comprises an additional side wall 1 located on the opposite side of the vertical wall 5 2 relative to the main side inclined wall 1. At least on one of the inclined side walls 1 an additional guide body 6 is installed in the form of a plane with
    0 sloping down at the upper edge of this inclined Wall 1 from its inner side with the formation of a gap in the form of a gap between the free edge of the additional guide body 6 and the vertical wall 2. The vertical wall 2 is made with a slot 7 located below the slot. The main guide body 5 is located on the lower edge of the slot 7 and is made in
    horizontal view
    a plane 8 with lateral guide planes 9 which are placed on the free edges of a horizontally set plane 8 with an inclination
    5 down.
    The device works as follows.
    The material to be separated, Q supplied continuously in a free stream to the device (figure 1), falls
    31
    on the inclined guide body 5, which deflects it in the direction of the inner surface of the inclined wall 1, along which the material flows in the direction of the braking element 4. Due to the upper horizontal plane of the braking element 4 having a wedge-shaped cross section, the material to be separated is braked in its flow and is diverted in such a way that it. falls on the vertical wall 2 at a right angle to it, as a result of which a slightly higher braking element 4 forms a movable layer of the material to be separated, which also performs a significant inhibitory effect. From this layer, a stream of material to be separated is formed, constant in its width and flow rate, passing as a thin layer from the discharge gap 3 into an electrically static free fall separator, which is located under the device (not shown).
