Abstract

1,052,426. Agglomerating synthetic plastics. CHEMISCHE WERKE HULS A.G. Oct. 4, 1963 [Oct. 5, 1962], No. 39122/63. Heading B1C. In a method of continuously agglomerating pulverulent synetheic plastics in a high-speed mixer M1 in which power consumption P (plotted against time t in Fig. 1) of the mixer motor A1 drops to a minimum in a heating-up period A before becoming constant for a period B, the time taken from the beginning of agglomeration is the instant at which P becomes constant, and agglomeration is terminated within the period B according to the desired particle size of the agglomerate, which is then discharged into a cooling mixer M2 (Fig. 3, not shown) and a fresh charge of plastics is introduced into the mixer M1, the power consumption of the motor A1 being monitored by a device L. The mixer M1 is heated during agglomeration and cooled during discharge of the product by steam or water respectively passing through a jacket H1. Agglomeration is preferably performed under reduced pressure maintained through a pipe 5, and a pipe 6 leads to atmosphere. Agglomerate is stored in a bin B provided with a maximum level indicator St for stopping the operational cycle when there is no room for further charge.
