Loss-in-weight metering feeding is a commonly used feeding method in double-stage granulators, which has several advantages over traditional dosing methods:

1. Accurate Measurement: Loss-in-weight metering feeding allows for accurate measurement of raw materials through the principles of gravity and weighing. It uses load cells or weighing instruments to measure the weight of the raw material to accurately determine the amount of material to be fed at any one time. Loss-in-weight dosing allows for more precise control of raw material inputs than rationing and ensures that each batch of pellets has the same recipe and composition.

2. Real-time adjustment: Loss-in-weight metering and feeding systems are usually equipped with controllers and feedback mechanisms that allow real-time adjustments to be made according to the actual feeding situation. By constantly monitoring and comparing the difference between the actual feed quantity and the set target value, the system can automatically adjust the feeding speed and time to achieve accurate metering and control. This real-time adjustment feature ensures that each batch of pellets has consistent quality and composition.

3. Easy to Operate: Loss-in-weight metering and feeding systems typically feature user-friendly interfaces and operator control panels for easy setup and monitoring by the operator. Operators can adjust feeding parameters such as target weight, feeding time and speed as needed to meet different production requirements. In addition, loss-in-weight dosing systems can record and store feed data for subsequent quality control and traceability.

4. Efficient and Reliable: Loss-in-weight weighing metering and feeding system can realize high-speed and continuous feeding process to improve production efficiency and capacity. At the same time, it has high reliability and stability, and can maintain consistent metering accuracy and performance over long periods of operation. This high efficiency and reliability makes loss-in-weight weighing metering and feeding widely used in mass production and continuous production scenarios.

In summary, the loss-in-weight metering feeding system in a two-stage granulator has the advantages of accurate metering, real-time adjustment, easy operation, high efficiency and reliability. It can provide accurate metering of raw materials, ensure consistent quality and composition of granules in each batch, and improve production efficiency and quality control.
