Granulator with water cooling and twin screw extruder
Laboratory granulation line with water cooling
Granulator, twin-screw extruder RES-2PN 2x20mm or RES-2PN 2x20mm and a cooling bath is a technically advanced tool for creating new plastic granules.
Twin-screw extruders RES-2PN 2x20mm or RES-2PN 2x20mm have excellent performance parameters and high functionality. They can be equipped with side dosing systems and Movacolor's advanced gravimetric or volumetric dosing systems. The dispensers can dispense powders, granules, liquids. Zamak Mercator additionally offers high-pressure liquid dispensers based on gear pumps. The stand is designed to test materials that can be cut without the use of cooling water directly at the extruder head.
The key device that has a decisive influence on the possibilities of conducting research is a laboratory twin-engine extruder. In the basic version, the stand is offered with a twin-screw extruder from the Vertex II series, model RES-2PM 2x24mm, and optionally with an extruder from the Vertex II series, model RES-2PM 2x20mm. These extruders have unparalleled possibilities in terms of offered parameters, equipment and configuration possibilities. The offered extruders can be made in versions for processing plastics, food and in an acid-resistant version applicable in pharmacy or for testing ceramic materials. The modular design of the devices included in the test stand allows you to change the configuration of the devices during use. The extruders can be equipped with dosing systems for powders, granules, liquids and other devices from the Zamak Mercator offer. The software of the extruders and the granulator can be adapted to the customer's expectations.
To sum up, the Zamak Mercator laboratory twin-screw extruders in combination with a granulator and a cooling bath for the extruded filament together form a perfect tool for creating new plastic mixtures, conducting reactive extrusion, creating dye carriers, filling plastics with mineral or metallic powders.
The laboratory granulator is designed for cutting plastic strands with a diameter of 2-4 mm, previously extruded on any laboratory extruder, into equal granules. The range of cutting lengths is wide, allowing to obtain granules and even flakes. It is an indispensable peripheral device in research lines. Its mobility and versatility allow it to work with various extruders.
The granulating system consists of a replaceable cutting knife driven by a 2.2 kW motor, feeding rolls and string guides. The rotational speed of the rotary knife can be fully adjusted. The line insertion system into the cutting zone is led outside the housing, which protects the operator from access to rotating parts. The feeding of the cutting lines is carried out by a separate drive with a power of 0.55 kW, which ensures the transport of the lines in a large range of linear speeds.
The control system allows you to adjust the linear speed of the cut lines and adjust the rotational speed of the knife. Thanks to the independent regulation of the rotational speed of the knife and the speed of feeding the lines, it is possible to obtain the required length of granules in a large range of the linear speed of the fed lines. The processor controlling the granulator enables independent control of the rotational speed of the blade and the linear speed of the cut filament, or it is possible to set the length of the cut granules for a fixed linear speed and the processor will select the rotational speed of the cutting knife itself. Changing the linear velocity will not affect the length of the pellets.
The granulator can work as an independent device or it can be connected to a unified control system in the entire laboratory line and thus setting and reading of operating parameters can be done from the extruder panel.
