The subject matter of the invention relates to apparatus for cooling or drying coarse-grained bulk material, comprising a plurality of trays mounted one above the other for rotation about a common axis, each tray being divided into a plurality of segments adapted to be tilted about a tilt axis extending in a radial direction of said common axis, means supporting said segments in the plane of the respective tray and permitting said segments to be tilted only within a determined angular range of rotation, and means for forcibly tilting each segment within said angular range. In prior art constructions, different means for forcibly tilting each segment in the said angular range have been required, depending on the time required by the feed material to pass through the cooling apparatus and on the number of trays employed in the cooling apparatus. Moreover, the hitherto known means for forcibly tilting the tray segments do not operate satisfactorily if the rotational speed of the trays in the cooling apparatus is increased. The apparatus according to the invention provides a solution to these problems by the use of an adjustable tilt lever.
Apparatus for cooling or drying of coarse-grained bulk material, comprising a plurality of substantially planar trays mounted one above another for rotation in one direction about a common axis, each tray being divided into a plurality of segments adapted to be tilted about a tilt axis extending in a radial direction of said common axis, means supporting said segments along a path in the plane of the respective tray and permitting said segments to be tilted only within an angular range of said rotation, said means including in association with each tray a tilt lever mounted for pivoting movement about a stationary tilt axis for tilting any one segment within said angular range, said tilt lever having a first lever arm projecting into the path of said segment support means, and a second lever arm adapted on pivoting said first lever arm to engage a respective segment for forcibly tilting it about its tilt axis, characterized in that said first lever arm (25, 24) of said tilt lever (20) is adjustable in the direction of rotation of said trays (10) relative to said second lever arm (23, 39).
