From the extensive range of dryers, Wittmann Battenfeld México will exhibit two Drymax dry air dryer models, a Drymax primus and a Drymax basic, plus a complete drying system consisting of a Drymax 300 battery dryer connected with two Silmax drying hoppers, each with 600 l capacity. The dry air dryers from the Drymax series are equipped with two desiccant cartridges and deliver continuous process air of constant dry air quality. The insulated Silmax drying hoppers come with the automatic, intelligent SmartFlow air distribution system as standard, which ensures a demand-based flow rate of dried air through the plastic granulate. To accommodate low material throughput rates, a compressed air dryer from the Card series will also be on display.
Wittmann’s portfolio of temperature controllers will be represented by models from both the Tempro plus and the Tempro basic series. The appliances from the Tempro plus series offer a high level of user friendliness as well as an extensive range of standard equipment. Their combination with digital flow rate devices, such as the WFC or the Flowcon plus, provides an intelligent temperature and flow control system for monitoring or automatic regulation of the flow rates.
The presentation of material loaders will include a Feedmax basic, a Feedmax plus and a Feedmax Clean for central materials handling systems, as well as a Feedmax S3 Net stand-alone loader for short-distance conveyance. The Feedmax Clean loader with dedusting function was specially developed to meet the increasingly stringent demands of circular economy and the resulting increase in plastic granulates with dust content. The Feedmax Clean has reached an extremely high level for the extraction of dust and particulate matter from regrinds.
Dosing technology will be represented by the Gravimax 34 gravimetric appliance. The gravimetric blenders from Wittmann are easy to operate, with outstanding features such as high-precision material valves, detachable stainless steel hoppers with corner windows, a removable weighing container and a highly efficient spiral mixer. High-precision dosing results down to single grams are secured by real-time weighing (RTLS). These can be retrieved for documentation via an OPC UA interface.
A selection from the wide range of Wittmann granulators will also be shown at the Plastimagen, including an S-Max 2 plus, an S-Max 3 screenless granulator, as well as the G-Max 23 and G-Max 33 cutting mill models. The granulators from the S-Max series are slowly rotating grinders used for in-line recycling of sprue from hard and brittle engineering plastics. The appliances from the G-Max series are compact beside-the-press granulators laid out for grinding soft to medium hard engineering plastics.
In the field of central material supply, Wittmann Battenfeld México will present at the Plastimagen different types of central materials handling systems in addition to the drying system. The E-Max 2 is a cost-friendly solution for controlling medium-d conveyance systems with up to 22 conveying stations. The M8 network control, preferably used for running entire systems, comes with a modular design and supervises the system from the material infeed station by way of access control, provides information about the status of the drying system and secures correct material feeding to every machine via an RFID-controlled Codemax coupling station.
