Weigh Feeder

In modern industrial processing, precision is the difference between profit and waste. Our weigh feeder is a high-performance dynamic metering system designed for the continuous weighing and controlled feeding of bulk materials, including powders, granules, and lumpy solids. Whether you are managing nitrogen-phosphorus-potassium (NPK) ratios in a fertilizer plant or raw meal in a cement facility, this belt weigh feeder ensures consistent mass flow with a dynamic measurement error of $\le 0.2\%$.

Description

As a leading weigh belt feeder manufacturer, we engineer our systems to solve the industry's toughest challenges: material clumping, belt tracking issues, and sensor interference. By integrating imported high-sensitivity load cells with intelligent automated controls, our feeders provide the reliability required for 24/7 continuous production environments.

Applications & Use

Our weigh belt feeder systems are the preferred choice for industries requiring rigorous automated control:

Fertilizer Production: Precise dosing of Urea, DAP, MAP, and Potash in NPK blending lines.
Chemical & Metallurgy: Continuous feeding of phosphate rock powder, additives, and ores.
Cement & Construction: Accurate batching of fly ash, clinker, and dry mortar components.
Alternative Designs: We also offer screw weigh feeder configurations for specialized fine powder applications where dust containment is the primary concern.

Key Benefits



Strict NPK Ratio Control

Achieve a dynamic metering error of $\le 0.2\%$, ensuring your fertilizer nutrients meet regulatory standards and customer expectations every time.



Minimized Maintenance Downtime

Our unique anti-drift belt technology ensures the belt stays centered even under heavy loads, preventing edge wear and unexpected mechanical failure.



Superior Signal Stability

Equipped with imported high-precision sensors (USA-made), our feeders offer exceptional anti-interference capabilities in harsh electromagnetic or dusty environments.



Lower Total Cost of Ownership (TCO)

We utilize standardized component manufacturing. All wear parts are globally compatible, significantly reducing your procurement costs and spare parts lead times.

How It Works

The weigh feeder operates on a real-time feedback loop. Material from the hopper feeds onto the belt, where load cells measure weight per meter and a sensor tracks belt speed. The controller calculates the actual flow rate, compares it to the target, and adjusts motor speed via VFD to maintain the set dosing rate.
