CO-ROTATING TWIN-SCREW EXTRUDERS WITH FUNCTIONAL MODULES AND SELF-CLEANING SCREWS
The planning of the process part of MARIS co-rotating twin-screw extruders concerns a group of functional modules composed of barrels and, at their inside, of transport and kneading elements at variable geometry, which are mounted on shafts for the motion/shear transmission. The concept of the functional modules originated from the necessity of achieving a perfect correspondence between the extruder hardware component and the process phases that can be identified with whatever compounding or reactive extrusion. The equipment capacity to meet with the process requirements can be found, first of all, in the technicians ability to precisely establish the physical or physic-chemical phenomena occurring inside the machine, both in qualitative and in quantitative terms.
More flexibility, more throughput, more competitiveness. To the above market requests Maris answers proposing a new TM extruder HS series, characterized by a D/d ratio 1,65, with a maximum screws speed of 1300 rpm. The torque has been increased of more than 20%, with respect to the HT series. This solution allows to use a bigger free volume, and an enhanced available torque, permitting a production increasing, either in case of high power request or when it is necessary to feed elevated percentage of fillers and/or additives.
Thanks to the most performing materials used to manufacture some of the elements composing the extruder, these machines can be applied in the more advanced compounding and reactive extrusion processes.
Maris co-rotating twin-screw extruders of VM series have been designed to increase the performances, for those processes which require, particularly, big quantities of soft fillers, mainly having low bulk density or long residential time (reactive processes) or efficacy removal of volatile components (solvents and monomers) present even in high percentages. Characterized by a ratio D/d of 1,78 and a maximum screws rotation speed of 1800 rpm, the specific torque value applied with respect to the cubed screws inter-axle, and the consequent advantages are:
AT THE CENTRE, THE CUSTOMER Ideas and objectives, men and technologies
The strength of a Company lies in its staff, who, with their ideas, skills and dedication combine to become the heart of the Company. Maris, fully aware of this, constantly relies on its staff to deal with every request of the customer, from the simplest to the most technological challenges.
Maris makes customer care its work philosophy, identifying their requirements and providing solutions, which will grant complete satisfaction in terms of results, with particular attention to innovation.
This is why Maris has always engaged in a wide variety of innovative technological challenges, such as reactive extrusion or the study of completely new processes, using all the experience and know-how acquired in more than 50 years in the demanding business of Plastics Compounding.
The objectives are reached thanks to Maris consolidated ability to operate as a team with the customer and all the participants on each specific project.
All the necessary resources, including the wide range of specific facilities at Maris, are involved and made available in order to find the most rational and high-performing solutions, both in the solely technical and technological procedures as well as where a synergistic efficiency is required.
The result is a whole range of ever more optimized productive processes, which allow our customers to respond efficiently to the requirements of a market which is becoming more demanding and sophisticated day by day.
