Since 1972 Colortronic has supplied into the extrusion processing field, gathering many years of know-how.
1989 saw a great advancement in this field with Colortronic introducing the loss-in-weight and batch gravimetric dosing units into the market.
2005 saw a complete overhaul of the equipment, which included not just the most technically advanced systems on the market, but easy to use touch screens, C2 live report software, extrusion control for both loss-in-weight and batch gravimetric systems and a vast range of host interfaces for remote control and monitoring of the complete blending and extrusion line.
2007 has seen the introduction of new mobile Dry-Flex dryers, recycling systems and the SER (smart, easy and reliable) range to build its customer base for smaller and stand alone systems.
New Small Dryer Line
Colortronic has introduced a new small mobile dryer line – Dry-Flex S.
The new Dry-FlexS range is based on the new ‘EFR’ design concept.
‘EFR’ (easy to use, functional and reliable) was the concept used for this new line, achieving a reliable, technically sound unit at low prices without non functional items which do not benefit the customer.
The units achieve dewpoints of -40ºC and are very energy efficient and compact. Together with the low price, this allows us to extend the stand alone product line to customers who understand the technical advantages and quality but who previously were unable to invest the additional monies required.
New Crystallisers for PET and PLA
Colortronic has launched a new modular range of crystalliser with energy, final moisture and time savings.
This new technology is based on over 20 years of know how and intensive evaluation of existing units on the market and their draw-backs.
Our new KT design offers the customer technical advantages such as minimum hydrolytic decomposition, reduced energy consumption, easy access to the hoppers, optimised air flow and heat input to keep the process stable. A vast amount of energy is saved due to a heat exchanger and air flow controlled automatically, based on the process feed back.
In some tests, our new KT system used a third of the energy compared to IRD systems and did not have the draw-back IRD infra red heaters can experience due to dust particles melting, effecting the performance, or the possible high maintenance cost of the IRD units.
Impact Disc Pulveriser PU 650

A new pulveriser with a vertical rotor axis
For the first time, Herbold Meckesheim GmbH presents a vertical constellation of the rotor axis. In comparison to conventional machines, the load on the bearings is considerably reduced.
The patented new design of the grinding discs has a positive influence on the dwell time and the final granular size. Consequently, with whirl sintering applications a 98% smaller 500 mm powder can be obtained, making a screening of oversize material almost unnecessary.
This will save investment costs on the peripheral equipment. In addition to this, the machine itself as well as the complete line is much more compact due to the omission of the screening machine and can be better adapted, especially if little space is available.
The PU650 construction size with a 650 mm rotor diameter will fill the gap between diameters 500 and 800 mm and is characterised by a very favourable price performance ratio.
The machine is used for the production of powders from rigid PVC waste in applications with tubes, profiles and plates, for the production of fine powders from polyolefines, for the production or whirl sintering and press plates as well as compounding applications.
Film Recycling

Better drying of wet film flakes with the Herbold Meckesheim Plastcompactor
A new solution has been found for drying recycled film flakes from washing, separation and drying plants for post-consumer film – the Herbold Plastcompactor.
Conventional dryers with centrifuges and electrical heaters are increasingly becoming bottle necks for such plants.
Due to the higher percentage of LLDPE stretch film and thinner film thickness being used (especially when recycling agricultural film) a more efficient drying is required.
One can only cope with a larger surface and the formation of capillaries of LLDPE stretch film if one manages to find new solutions.
The Herbold Plastcompactor with its preceding pressure screw provides an additional dewatering step due to its kneading effect. Considerably less energy is needed to evacuate the humidity than would be possible with thermal and centrifugal procedures.
If a high throughput is required, a plastcompactor is combined with a centrifugal dryer. Throughputs from 300 to 1,000 kg per hour can be obtained with three different plastcompactor sizes with disc diameters from 300 to 700; according to the throughput the installed drive capacity is 45 to 200 kW.
