    The drying and cooling of bulk materials are effected in a vibratory channel (1), divided into a plurality of compartments by partitioning walls (2). The walls (2) provide heating or cooling surfaces and are comprised of conduit assemblies. These walls delimit channels which narrow in the flow direction. At about midway of the vibratory channel (1), a filter section (7) is arranged so that the finished product is subjected only to a limited heat treatment.

    The invention relates to a drying technique.
    A known apparatus for drying bulk materials comprising a housing with a channel for conveying bulk materials and partitions provided with heat exchanging surfaces l.
    Closest to the invention is a drying or cooling installation for bulk materials, predominantly lime and coal, comprising a housing with a vibrating tray serving to transport bulk materials from the loading unit to the discharge chamber and divided by partitions located in the direction of material transport in cross section to the compartment , and the partitions are provided with heat exchange surfaces for the passage of the heating or cooling medium 2.
    However, the known installations are not high enough heat and mass transfer.
    The aim of the invention is to intensify heat and mass transfer by mixing bulk material.
    This goal is achieved by the fact that in a drying or cooling installation for bulk materials, mainly lime or coal, holding the body with a vibrating tray, used to transport bulk materials from the loading unit to the unloading and divided by partitions in the direction of material transportation in cross section, into compartments, the partitions being provided with heat exchanging surfaces for the passage of a heating or cooling medium, the partitions are made in the form of fin screens the protuberances and recesses of vertically forming longitudinal channels unchanged Conf iguratsii in the conveying direction, wherein the bulge and recesses on adjacent screens offset relative to each other.
    In addition, the compartments between the partitions are made of variable cross-section, decreasing in the transport direction the material from the loading unit to the unloading, and the bottom of the tray in each compartment has a section for screening fine material in the form of a grid located in the middle between the loading and unloading units.
    FIG. 1 shows a vibrating tray, the section in FIG. 2 - installation with two partitions, cut; in fig. 3 - fin screens; in fig. 4 - installation with five partitions, top view.
    The installation includes a housing 1, a vibration tray 2, partitions 3 with convexes 4 and depressions 5, grids 6, loading 7 and unloading 8 nodes, inlets 9 and outlet 10 of the heat carrier.
    Drying or cooling installation for bulk materials works as follows.
    The dried material enters the body 1 through the loading unit 7 and is dried in a suspended state by the coolant flowing through the pipe 9 for supplying the coolant. During the drying process, the bulk material rises in a vertical direction with the flow of heat carrier and due to the operation of the vibrating tray 2.
    The material hits the convexity 4 and the recess 5 of the partitions 3 and bounces off them in the direction of the middle of the compartments formed by the partitions 3. In this case, intensive mixing of the material being dried occurs, and at the same time the cooling or heating effect is equalized so that the discharge unit 8 provides uniform temperature of the bulk material. Instead of fin screens, other structures can be used, such as heat transfer plates, through which condensable or evaporating water flows. grevayuscha or cooling medium.
    During drying during transportation of the material being dried, the finely divided material is sifted through the grids 6 located in the middle between the loading 7 and the unloading 8 nodes into compartments formed by partitions 3.
    The compartments formed by the partitions 3 narrow in the direction of transport, as a result of which a greater density of the bulk material is achieved near the discharge unit. The exhaust coolant is discharged through the nozzle, 10 of the heat carrier discharge, and the dried Material enters the discharge unit 8.
    The invention makes it possible to significantly intensify heat and mass transfer by mixing bulk material.
