Dynamic dosing system
Dosing
At the heart of the system is a vibratory feeder working in combination with strain gauge weighing modules. Batch preparation is carried out with an accuracy of up to 100 g, while weight measurement is performed with an accuracy of up to 10 g. Depending on the type of material, batch size and available weighing time, even greater dosing precision can be achieved.
Each dispensed batch is weighed and verified every time. In the case of non-homogeneous raw materials, the prepared batch may fall outside the specified tolerance range. In such cases, it can either be automatically discharged into the reject container or corrected manually.
Depending on whether the ingredients can be mixed or need to be fed sequentially into the ladle, we use a belt conveyor. The conveyor structure has been designed in such a way that bulk materials do not adversely affect its operation.
Silos
The number of tanks and their capacity are selected according to raw material consumption and the expected frequency of refilling. Reaching the minimum level, indicating that the tank needs to be replenished, is signalled on the operator panel.
If the client does not have an overhead crane, we can equip the system with our own big bag loading solution. Direct dosing from big bags is also possible.
Available options
- communication with the analyser and dynamic batch selection,
- remote triggering of additive charging into the ladle by remote control, for example by a forklift operator,
- use of local extraction systems at transfer points,
- ATEX-compliant version,
- simultaneous supply of two ladles for two production lines,
- discharge of rejected material into separate containers.
Customer benefits
- fully automated dosing cycle,
- elimination of manual tasks related to weighing and charging additives into hot foundry ladles, thereby reducing health and safety risks,
- full control over the quantity of additives dispensed from each tank,
- automatic monitoring of every stage of the dosing cycle,
- no need for operator involvement in the hazardous area,
- reduction of the dosing cycle time to 4 minutes.
