In the wake of the developments in processing methods, the technology of ancillary equipment is also making advances. The key drivers of the developments are cost savings from increasing the energy efficiency of dryers and greater precision in dosing equipment.

Closing a Gap

In the field of material handling, we continue to find a broad spectrum of products to feed, mix, and meter granulates and powders. Precision hardware and connectivity within systems show the way to more efficient material handling processes.

The vacuum needed for conveying bulk material can be generated with side channel blowers, but it is much more energy-efficient to use vacuum pumps. These can slash the power consumption needed for vacuum generation by up to 70 %.

Pneumatic conveying of a raw material from the silo to the processing line does not sound like a very spectacular task. But in everyday routine, problems often occur. The manufacturer AZO is pinning its hopes on software that uses artificial intelligence to find the optimum operating point.

With the help of the coupling station, fast material changes become normal practice, material sources such as dryers, roller containers or external silos can be used by several consumers, and RFID monitoring ensures a faultless production process.

RFID antennas and tags on every coupling make sure that correct connections are established in every case between material feeding pipelines and processing machines

PET flakes can now be processed without pre-drying into pellets using Coperion ZSK twin screw extruders and reprocessed back into bottles again with the quality of virgin material.

Coperion ZSK twin screw extruders provide very good devolatilization with short residence times in the process section as well as very high dispersion, contributing significantly to high end product quality

When the Silo and the Hopper Talk to One Another

Pultrusion is a highly attractive solution for synthetic resin processing. It is regarded as the standard technology for the automated production of lightweight but highly resilient profiles and molded parts made of GRP and CFRP. The provision of a high-quality resin matrix for the continuous impregnation of fiber reinforcements is a decisive process stage here. The dosing, mixing and application systems from Tartler are specially  matched to this process step.

One of the first processing stages of pultrusion: introduction of the fiber reinforcement into an impregnation tank or profile mold filled with liquid synthetic resin.

The Art of Processing Resin

By using a vacuum, powder or granular materials can be transported without any problems. Depending on the application, different vacuum pumps for pneumatic suction conveying can be considered. The decisive factors here include the length of the conveying distance, the type of conveying and the required differential pressures.

Economical Conveying of Bulk Goods

In a Vacuum

Scholz Dosiertechnik presents its new Flex series. The specialists from Großostheim are thus expanding the market standard with paddles that can be adapted to the product to be dosed.

Since the 1990s, feeders with a paddled PU hopper have proved successful at metering most non-free-flowing powders. With its new Flex model series, Scholz Dosiertechnik is now extending the market standard with highly versatile paddles that can be adjusted to the product for metering. Not only the inclination of the paddles, but also their distance from the PU hopper can be adjusted in several steps. Even differently shaped paddles are feasible. The feeders come equipped as standard with a separate paddle-drive motor for precision adjustment of the paddle frequency. The Flex models cover typical feeding needs ranging from very small amounts of additives to fillers in the high liter range. The feeders fit in perfectly with Scholz’s modular concept: placed on a digital platform scale, the Flex feeder acting in combination with the plug-and-play control unit can optionally serve as a continuous gravimetric or batch-feeder system to suit the metering task at hand.
