Dosing systems and Loss-In-Weight feeders
We supply dosing systems for batch and continuous mixing lines, as well as equipment and systems for the handling and packaging of bulk materials. Our long experience in weighing, dosing and conveyor equipment projects enables us to find the most cost-effective solutions for your needs.
Continuous and batch process dosing systems
Continuous dosing systems are based on dosing belt feeders and Loss-In-Weight feeders. Dosing systems for batch processes are implemented with hopper scales and dosing equipment suitable for the raw materials to be processed. System automation typically includes electrification as well as control logic and user interface. In a single feed supply, all of these can be integrated into the weighing controller or the feeder can be connected via a field bus to the automation system.
The Loss-In-Weight feeder measures and controls
In a Loss-In-Weight feeder, material is typically fed into the process at a set mass flow rate (kg / h or t / h). Usually it consists of a hopper scale, on the bottom of which a dosing screw, a vibrating feeder or a rotary feeder is speed controlled. The Loss-In-Weight Controller measures the mass flow leaving the feeder and controls the feeder speed to reach the desired mass flow. The filling of the weighing hopper is performed automatically when the weight of the container drops below the lower limit. The hopper is intended to be filled as quickly as possible because the feed must be held at constant speed during filling. Depending on the material, even during filling, the mass flow can be adjusted according to various algorithms to minimize the control deviation and, at the same time, the change of mass flow at the end of filling.
Loss-In-Weight feeders for the process industry
We have supplied Loss-In-Weight feeders in a variety of sizes to several different industries. Our dosing systems and Loss-In-Weight equipment are most used by big companies in process industry, for example in the metallurgical, feed industry or, for example, plastics industries.
