1)Fertilizer batching machine is a high-tech product integrating conveying, weighing and measuring and quantitative control.
2)It can continuously and uniformly carry out dynamic control, quantitative feeding and continuous measurement for lump, granular and powdery materials.
3) Complete the series of closed-loop control with microprocessor, actuator and sensor.
4) When the system is running, the materials conveyed are measured by the belt dosing scale, and the received weight and speed signals are processed by the computer calculator and transformed into the cumulative value and instantaneous flow rate, and the cumulative value and instantaneous flow rate signals are transmitted to the industrial control machine (upper computer) by the RS-485 port
5) 4 ~ 20mA analog current signal transmitted to the frequency converter regulator, and then by the frequency converter regulator to adjust the size of the silo outlet, when the flow rate increases, the size of the outlet closed, and vice versa, increase the size of the outlet, thus making the material flow and the stage of the cumulative value of flow and speed signals are processed and converted into the cumulative value and instantaneous flow.
6) Make the flow rate of the material and the cumulative amount of the stage are maintained in the set range, and then complete the measurement and dosing of the material.

Fertilizer batching machine is a crucial machinery in BB fertilizer production line.
1) The material enters into the lower feeding port from the silo, and falls into the belt automatically through the adjustable material flow gate, the belt is skirt belt, which can prevent the material from overflowing.
2) The circular belt rotates at a constant speed, the material passes through the weighing section of the scale body during the belt operation, the load cell measures the weight of the material required for dosage, and the speed of the dosage scale is controlled by variable frequency adjustment.
3) Through the frequency conversion adjustment of the fertilizer batching machine, the rotating speed of the batching scale is controlled, and the materials fall into the collecting belt at the collecting section at the end of the belt.
4) The scraper is provided under the belt at the discharge port to clean up the adherents of the belt and improve the dosing accuracy of the fertilizer batching machine.
Batching machine generally consists of four parts: scale body, feeding mechanism, unloading mechanism and electric control system.
1) Feeding mechanism
The feeding mechanism adopts several forms such as forklift feeding and screw feeding.
2) Unloading mechanism
The general unloading mechanism adopts cylinder arc door unloading, vibration unloading, screw unloading, rotary feeder unloading or direct use of pneumatic (electric) valve unloading and other forms.
3) Scale Body
Most of the scales are made of metal materials such as angle steel, channel steel, square tube, etc., and are finished by welding, grinding, plastic spraying or painting.
4) Electrical control system
The electrical system is mainly composed of weighing unit and control unit.
Fertilizer batching machine weighing unit using load cell + with controller + electrical components for control, the way the quality is stable, debugging is relatively complex, inexpensive, simple function.
In addition, some foreign and domestic large companies often use a control mode is: load cell + weight transmitter + PLC + touch screen (industrial computer). The quality of this method is excellent and very stable, simple debugging, easy operation, rich in functions but high cost, so the control method is the best choice for large and medium-sized users.
