All About Weigh Belt Feeders

The weigh belt feeder has brought a perfect automation solution, replacing inaccurate and labor-intensive manual weighing methods. The weigh belt not only helps measure continuously but also controls material flow from the hydraulic lift table, ensuring the production process is seamless and stable. Join Naltako to explore a comprehensive view of this advanced equipment.

Structure of the weigh belt feeder

A complete weigh belt feeder system consists of many components coordinating smoothly to achieve the highest accuracy. The main parts include:

• Mechanical part: Includes a weighing frame made of sturdy steel, load-bearing conveyor belt, and roller system. These components create a solid platform for materials to move and be weighed.
• Sensor system: This is the “heart” of the system. It consists of force sensors (load cells) to measure the weight of material on the conveyor and speed sensors (encoders) to measure the velocity of the conveyor. Signals from these two sensors are crucial input data for calculation.
• Control system: Includes the weighing head (indicator) and controller (PLC, inverter). The weighing head will process signals from the load cell and encoder to calculate flow rate and total mass. The inverter will control the conveyor speed to maintain a stable flow rate according to settings.

Role of the dosing weigh belt

The role of the dosing weigh belt in industries is extremely important. It helps:

• Product quality control: Ensures every product produced has uniform mass, meeting set standards, especially in industries requiring high precision like food and pharmaceuticals.
• Production process optimization: Automates the weighing process, minimizing errors due to human factors, helping the production line operate continuously and efficiently.
• Cost saving: Minimizes material waste and labor costs, thereby optimizing profits for the business.

Operating principle of the weigh belt feeder

The operating principle of the weigh belt feeder is based on the basic formula: Flow rate (Q) = Mass (m) x Velocity (v).

• When material is fed onto the conveyor, the force sensor (load cell) measures the weight of the material on a specific conveyor section.
• Simultaneously, the speed sensor (encoder) measures the moving velocity of the conveyor.
• All these parameters are transmitted to the control indicator. The indicator processes the data and calculates the material flow rate running on the conveyor.
• Based on the preset flow rate, the controller automatically adjusts the conveyor speed through the inverter to maintain a stable flow, ensuring the dosing process is accurate.

Applications of the dosing belt

With outstanding advantages, the dosing belt is widely applied in many industries:

• Mining and construction material industry: Dosing coal, stone, cement, sand, gravel… helping control output and mix raw materials.
• Food industry, agriculture: Dosing cereals, grains, sugar, flour, animal feed… ensuring products have standard weight.
• Chemical and fertilizer industry: Accurately controlling the amount of chemicals and fertilizers to ensure mixing formulas and finished product quality.
• Energy sector: Dosing coal, limestone powder in thermal power plants.
