Dosing Technology

To dose dry ice pellets from their transportation boxes into special isolation containers, JOEST delivered a system solution to the global specialist ASCO Carbon Dioxide this year. Realistic tests at the JOEST Test Center gave insight to the handling of dry ice at extremely low temperatures – at standard pressure -78°C – and the effects it has on the equipment. This data was analyzed by product specialists at JOEST and implemented in the details of the engineering design. The client’s demand was to dose the dry ice pellets with high precision, but without destroying them. A big challenge was the large difference in temperature between the product and the environment. Varying transportation boxes on the feed end, adjustable batch sizes and intermediate storage of the box volume were additional features demanded for the system solution.

In June this year, JOEST delivered a customized solution for casted pan dosing to a German client. This specially designed alloy plant features a remarkable dosing precision for aggregates. The client’s demand was to achieve the best precision possible when dosing the two components manganese-iron and silicon-iron. The two hoppers are loaded with the aggregates by the client. Dosing feeders then feed the two container wagons. The wagons are pre-dosed to roughly 20 kg to speed up the actual dosing process. The downstream feeder, which can pivot by 90°, then feeds the material directly into the pouring stream. Depending on the aggregate, the system is designed to dose between 5 and 10 kg and each scale reaches a precision of up to 50 grams.

For a client building a phosphatizing plant as a general contractor for a German automotive company, JOEST designed, manufactured and delivered a large system solution this year, to feed and refill the plant. The project started in 2019 but was temporarily set on hold due to the Covid-Pandemic. It was later picked up again and went into production this year. The task was to dose forging parts into baskets provided by the client, based on the demanded formula. The parts are supplied in two different steel containers. The filled baskets are fed into the phosphatizing bath. After the phosphatizing process, the containers are removed and emptied.
