Latest Machinery designs and sets up intensified Chemical processing machine transformation lines using reactive extrusion techniques. The latest Machinery co-rotating twin-screw technology and the company’s long experience in product development ensure the efficiency of this highly flexible and scalable process.
The twin-screw extruder’s remarkable mixing capabilities make it possible to process reduced volumes of materials in each production cycle. Twin-screw extrusion ensures a maximum level of safety in the processing of chemicals and energy materials by radically reducing the risk of explosion and spontaneous combustion.
WHAT ARE THE CHARACTERISTICS OF A REACTIVE EXTRUSION TWIN-SCREW LINE?
Each reactive extrusion process used in the chemical transformation is custom-made with the participation of the industrialists involved.
The solid raw materials stored in silos or big bags are conveyed to a buffer hopper located above volumetric or weigh feeders by a pneumatic conveyor belt. The liquids are pumped by piston and/or membrane pumps and injected in the twin-screw extruder sleeve at the best location for the reactive extrusion process.
Reactions are carried out in homogeneous or heterogeneous phase in the twin-screw extruder, which becomes a continuous extruder-reactor, with exceptional mixing capabilities.
The sleeves of the atmospheric or vacuum degazing ports help remove moisture or residual monomers.
THE ADVANTAGES OF TWIN SCREW EXTRUSION FOR CHEMICAL TRANSFORMATION
- Acceleration of chemical kinetics according to reactions under the effect of temperature and pressure
- Intensified processing, thanks of to thorough mixing between chemical reagents allowing to reduce mixing time and generating energy savings through efficient heat exchange
- Containment of the reaction and the use of smaller quantities of products, leading to enhanced safety conditions for operators and reduced environmental risk
- Higher productivity compared to conventional batch processing
- Control of the reactions along the line, including pressure and temperature control
- Consistent quality thanks to continuous processing, facilitating reproducibility (recording and archiving of parameters
