PALLMANN Plast-Agglomerator principle of operation

The worldwide proven system for the continuous production of free flowing granules from thermoplastics of all kinds. The Plast-Agglomerator, type PFV is available in six different sizes with throughput capacities from 20 to 4000kg/h. Principle of operation: The feed material is fed into the agglomerating chamber by means of a dosing screw. Frictional heat and high pressure, produced between the agglomerating vane and the die, agglomerate the material and press it through the special hole size of the die. The processing temperature is right below the melting point of the corresponding plastic material. The retention time in the agglomerating chamber is only a fraction of a second. Material penetrating the die is cut by rotating knives and conveyed by the cooling air of a fan into the hot-melt granulator where the material is cut to equalsized granules. The hole size of the selected screen installed in the hot-melt granulator determines the size of the granules.
