READ MOREBatching scales are designed for feeding various bulk materials, dynamically weighing, accumulating, and controlling flow rates during the feeding process. They are widely used for weighing and feeding various bulk materials in industries such as metallurgy, building materials, chemicals, and food. Weighing capacity ranges from 50 kg to 1200 tons per hour, belt widths from 300 mm to 2000 mm, and lengths from 1 meter to several dozen meters. Available in open, semi-enclosed, and fully enclosed configurations, they are suitable for diverse sites and meet diverse user requirements.
Structural Principle:
The belt feeder receives material passing on the belt. The load cell under the weighing frame measures the weight of the material on the belt. A digital speed sensor mounted on the tail drum or rotating device continuously measures the feed speed. The pulse output from the speed sensor is proportional to the belt speed. The speed signal, along with the weight signal, is fed into the ZJ-820 belt feeder controller, which generates and displays the accumulated and instantaneous flow rates. The feed controller compares this flow rate with the set flow rate. The controller's output signal controls the speed of the frequency converter to achieve quantitative feeding. Various relevant parameters can be set by the host PC, and the system can be automatically controlled through communication with a PLC.
Technical Advantages:
1. The cross-spring of the metering sensor is sealed and spray-coated for improved corrosion resistance.
2. Stable performance and strong anti-interference capabilities, with a 48-hour drift of ≤0.5%.
3. Low system control error, with material metering error ≤1%.
4. A material cleaning device is added to the scale to keep the belt clean and improve metering accuracy.
5. Power outage protection ensures that all data is preserved even during power outages.
