<p>It is described a die of pelletizing press, it is formed by circular steel plate (1), in which are formed axially arranged channels (2) with a circular diameter, consisting of a conical slope (21), to which is connected a cylindrical section (22). The top angle alfa of the conical slope (21) of a channel (2) has size alfa = 25 ° to 30 ° and the length of the cylindrical section (22) of the channel (2) is 3-times to 4-times greater than the diameter of the bore of the cylindrical section (22) of the channel (2).</p> |
