There may be many reasons for the belt conveyor stall alarm. The following are some possible reasons:

· Belt slack or breakage: Belt slack can lead to reduced transmission efficiency and eventually stalling. A broken belt will completely interrupt the transmission and cause shutdown.

Belt slippage: If there is insufficient friction between the belt and the drive pulley or drum, or there is external material covering or lubricant, the belt will slip, causing stalling.

· Transmission system failure: Failure of key components such as gears and chains in the transmission system, such as broken teeth and chain detachment, may cause stalling.

· Motor failure: Motor failure, such as power failure, overload or short circuit, may cause the motor to fail to operate normally, thereby triggering a stall alarm of the belt conveyor.

· Sensor failure: The sensor installed on the belt conveyor is faulty or damaged, which may cause the sensor to be unable to accurately monitor the movement status of the belt or drive wheel, resulting in false alarms or failure to provide timely alarms.

· Other factors: such as material accumulation, blockage, excessive workload, unbalanced load, etc. may cause the belt conveyor to stall and alarm.

When a belt conveyor stall alarm occurs, the cause needs to be promptly investigated and corresponding measures taken to ensure the safety and normal operation of the work process. The specific reasons require detailed inspection and analysis based on the actual situation.

How Belt Stall Monitors Work

The belt stall monitor is a device used to monitor the speed and status of the belt drive system to ensure the safety and stability of the working process. The basic principle of the belt stall monitor is to monitor the running speed of the belt in real time through a sensor or encoder installed on the belt. If the belt speed is detected to be lower than the set threshold or an abnormal situation occurs, the monitor will send out an alarm signal or trigger a shutdown device to stop the operation of the conveyor or other related equipment.

Belt stall monitor functions and features include:

· Real-time monitoring: Able to monitor the running speed and status of the belt, detect and alarm in time.

· Stall detection: It can detect the stall situation of the belt. If the belt speed is lower than the set threshold, the monitor can detect it in time and take corresponding measures.

· Alarm function: When the belt speed is abnormal or stalls, the monitor can send out a sound or light signal to alert the operator.

· Shutdown device: The monitor can also be connected to the shutdown device of related equipment. When the belt stall is detected, the shutdown device can be triggered in time to ensure the safety of operators and equipment.

· Durable and reliable: The monitor is durable and reliable, and can continue to work and maintain sensitivity under various environmental conditions.

Generally speaking, the belt stall monitor can provide timely speed monitoring and alarm functions to ensure the safety and stability of the working process. The specific monitor model and performance characteristics need to be selected based on actual usage needs and equipment requirements.
