Automatic feeder dedicated inverter

Automatic feeder dedicated inverter

Product Introduction

The belt feeder is at the front end of mining machinery such as Raymond mill and crusher. The feeding speed and feeding amount of the belt feeder play a key role in the operation of the equipment. The traditional belt feeder uses a speed regulating motor to manually control the feeding speed and amount. The feeding speed does not change much, which is intermittent feeding. This not only requires a dedicated person to be on duty for the feeder, but also causes uneven feeding. Too much feeding will cause the Raymond mill to be blocked, and too little feeding will result in low output. In response to the situation of this equipment, our company has specially developed a dedicated frequency converter for the feeder. It only needs to detect the motor current of the Raymond mill with a mutual inductor and send it to the frequency converter to achieve unmanned operation and uniform feeding, which greatly reduces costs and improves efficiency.

Function Introduction:

1. Power range: 0.75KW~400KW .

2. Speed sensorless current vector control.

3. High starting torque, open loop vector control can output 150% rated torque at 0.5Hz .

4. Simple control: A current transformer is passed through the main motor line, and the detected current signal is connected to the inverter.

5. Automatic voltage regulation output ( AVR ): When the grid voltage changes, the output voltage can be kept constant.

6. Excellent braking performance: When quick stopping is required, suitable braking resistor can achieve quick stopping.

7. Protection function: Since there is a lot of dust in mining machinery such as Raymond mill, the inverter has made special protection measures for such bad environments to ensure the normal operation of the inverter.

8. Parameter backup and restore: After the user sets the parameters, they can be backed up and restored with one click.

Application areas:

Applications of mining machinery such as Raymond mill and crusher.
