Heating-and-melting unit is served with one operator.
Heating-and-melting unit is intended for preparation of the molding mixture consisting of the following raw materials - wastes of polymers, such as polyethylene of high and low pressure, polypropylene, ABS plastic; quartz sand; dye. Preparation of mixture involves uniform mixing of the components, melting (plasticization) of the polymeric binder being exposed to heating to produce uniform plastic composition suitable for further molding.
Principle of operation.Heating-and-melting unit is controlled by the control cabinet. The screw is rotated by means of drive unit. Prepared uniformly pre-mixed mixture of the polymeric components is supplied in the preheated working chamber of the heating-and-melting unit through the receiving hopper and pushed by the screw deeply into the working chamber. The screw rotates and provides stirring of the composite mixture and its motion within the working chamber with passing through three heating zones. Within the first heating zone the mixture is heated and dried (residual moisture is removed), within the second (medium) zone the polymers are plasticized and thereby a homogeneous composite mixture is obtained, within the third zone the mixture temperature is maintained and therefore its consistency required for its subsequent molding. Ready mixture is moved by the screw to the outlet located in the output (front) housing flange. This opening is closed with gate valve, which is opened by moving the handle upwards. To lock in the closed position press on the handle downward until it stops.
