Batching System

The OFEC Automatic Batching System is a continuous batching solution designed specifically for organic fertilizer production lines, suitable for precisely mixing, batching, and feeding 2–8 different materials.

Product Overview

The system employs dynamic weighing technology to continuously measure material weight during belt conveying and automatically adjusts the feeding speed to ensure accurate and stable proportions of all raw materials.

Widely used in organic fertilizer and organic‑inorganic compound fertilizer production, it is a critical front‑end device for ensuring consistent product quality.

Equipment Components

The automatic batching system mainly consists of the following components:

● Belt scale body

● Load cells

● Speed sensors

● Frequency inverter

● Motor

● Reducer

● Control instruments / PLC control system

● Belt conveyor

● Hopper and feeding device

Working Principle

The automatic batching system operates on the principle of dynamic continuous weighing. During operation, load cells continuously detect the instantaneous weight of material on the belt, while speed sensors simultaneously measure the belt linear velocity. Both signals are processed by the control system, which then outputs a control signal to adjust the frequency inverter, thereby changing the motor speed and belt speed. This ensures that the actual feed rate continuously tracks the set value, achieving precise quantitative feeding.

The conveying capacity and accuracy of the batching system are closely related to material characteristics, belt speed, and other factors. When selecting equipment, parameters such as material name, particle size (mm), bulk density (t/m³), target flow rate (t/h), and site temperature should be taken into consideration.
