According to the needs of some special occasions of belt conveyors, there is an external electric drum with the deceleration device inside the drum body and the motor outside the drum body, which is between the separated drive and the electric drum drive.
Compared with the separate drive device, the electric drum has many advantages such as compact structure, high transmission efficiency, low noise, long service life, smooth operation, reliable operation, good sealing, small space occupation, easy installation, etc., and is suitable for various applications. Work in harsh environmental conditions. Including wet, muddy, dusty working environment. It can replace the widely used motor-reducer type external drive device to form a belt conveyor, which can transport bulk materials such as coal, ore, sand, cement, flour, etc., as well as complete items such as sacks and equipment.

READ MOREHow to achieve centralized control of Electric Pulley Drive?
1. Control system design
PLC controller: Using a programmable logic controller (PLC) as a central control unit, multiple electric rollers can be programmed and controlled to ensure that they run synchronously according to the predetermined logic and time.
Human-machine interface (HMI): The HMI provides a user-friendly operation interface, allowing operators to easily monitor and control the operating status, set parameters and alarms of the electric roller.
2. Communication protocol
Fieldbus: Using fieldbus protocols such as Profibus, CANopen or Modbus, real-time data transmission between different devices can be achieved to ensure efficient communication of the control system.
Wireless communication: In some cases, wireless networks (such as Wi-Fi or Bluetooth) are used to achieve remote control and monitoring to improve the flexibility of the system.
3. Sensors and feedback
Position sensors: Install sensors to monitor the operating status of the electric roller, such as position, speed and load, to ensure that the system can be adjusted in real time.
Feedback control: Monitor the gap between the actual operating status and the set target through the feedback mechanism, and dynamically adjust the operating parameters of the electric roller.
4. Centralized control cabinet
Control cabinet layout: Integrate all electrical components, including PLC, relays, inverters and terminal blocks, in the control cabinet for easy maintenance and management.
Overload protection and safety devices: Set up overload protectors and emergency stop devices in the control cabinet to ensure the safety of the equipment.
5. Remote monitoring
Cloud platform: Use IoT technology to upload the data of the electric roller to the cloud platform to achieve remote monitoring and data analysis.
Alarm system: Set up alarm functions to promptly notify operators of equipment abnormalities or failures for quick response.
6. Practical application examples
In industries such as mining or metallurgy, centralized control systems can monitor the status of electric rollers through PLC and HMI in conjunction with field sensors. Operators can view the operation of all electric rollers through the central control room and make necessary adjustments to ensure efficient operation of the production line.
