Product Description

Single Screw Reciprocating Extruders

The reciprocating single screw extruder is a continuously operating single screw machine, but its unique operating principle and its special kneading type screw and barrel design differentiates it from traditional single screw extruders. The screw of traditional single screw extruder machine has a continuous spiral .With this machine the spiral of screw is divided (broken) in three equal gaps per revolution , resulting in the kneading flight . Three rows of kneading pins are fitted in barrel and liners at 120 deg apart. This (pins) act as a kneading and cleaning (screw flights) media.

This resulting very easy cleaning of screw. The specially designed gear box with special mechanism generates reciprocating and rotary motion (oscillating) for screw. Also main barrel of machine is kept split for easy cleaning, and change over of replaceable items. The easy clamp system ensures decrease in change over time. The operating principle depends only on the movement of kneading flights relative to the kneading pins. The mechanically synchronized mechanism executes radial and axial movement to the screw. The relative motion between kneading flights and pins produces shearing gap in which the product is subjected to shearing with reorientation. And because of that:-

  • Homogeneous mixing of product in very short of processing screw is possible.
  • Smooth processing conditions due to balanced shearing and electronically temperature control system.
  • The machine barrel is having three different thermal zones, controlled by water circulation.

One can start the plant by pre-heating the machine to temperature of 10 to 15 deg C above the melting point of the resin to be processed. As soon as the plasticized melt emerges from the die, the heat control is switched over to the direct cooling (chilled) water supply to the temperature zones for production i.e. removal of excess heat. As a result some of energy introduced by mechanical dispersive mixing is removed, i.e. the melt temperature is kept low.

This in turn accelerates dispersive mixing and ensures smooth running of plant to produce quality product from it.
