Belt conveyor slippage can occur for a variety of reasons, here are some possible causes:

Inappropriate belt tightness: If the belt is too loose or too tight, it will cause slipping. If it is too loose, the belt will not be in close contact with the conveyor drum and lacks sufficient friction; if it is too tight, it will increase friction, but it will also easily cause excessive wear.

Poor drum sliding: If grease, dirt or other substances appear on the surface of the conveyor drum, it will affect the friction with the belt and cause slipping.

Belt aging and wear: Belts that have been used for a long time or are exposed to harsh environments will gradually age, wear, and lose friction.

Overload: If the material carried by the conveyor exceeds its design carrying capacity, the friction between the belt and the drum will increase, causing slipping.

Ambient temperature is too high: A high temperature environment will soften the belt, reduce friction, and make it easy to slip.

Humid environment: If the conveyor runs in a humid or watery environment, moisture may adhere to the belt and drum, reducing friction and causing slippage.

In order to solve the problem of belt conveyor slippage, the following measures can be taken:

1. Adjust the tightness of the belt so that it is in close contact with the drum but not excessively tight.

2. Clean the surface of the drum regularly to ensure that there is no grease, dirt or other substances attached. Regularly inspect and replace worn belts.

3. Avoid overload operation and use the conveyor reasonably according to the designed carrying capacity.

4. In high-temperature environments, consider taking cooling measures, such as increasing ventilation or using cooling equipment.

5. In a humid environment, try to prevent moisture from entering the conveyor, or use waterproof measures, such as installing a cover or waterproof coating.

Please note that solving the slipping problem may require analysis and adjustments based on specific circumstances. If the problem cannot be solved, it is recommended to consult a professional for further inspection and maintenance.

In order to promptly detect whether the belt conveyor is slipping and take corresponding control measures, we can choose relevant sensors for real-time monitoring, such as the belt slip detector, which is a device used to monitor whether the belt conveyor is slipping. It can determine whether slipping occurs by detecting parameters such as belt speed, tension or friction, and promptly issues an alarm or takes corresponding control measures.

Belt slip detectors usually include the following main components:

Sensor: The sensor is used to sense the operating status of the belt and obtain data on relevant parameters. Common sensors include speed sensors, tension sensors, friction sensors, etc.

Controller: The controller receives the data collected by the sensor and analyzes and judges based on the set threshold or algorithm to determine whether slippage occurs. If slippage is detected, the controller will trigger corresponding alarms or automatic shutdown and other control actions.

Display: The display is used to display the current operating status and alarm information. The operator can understand the working status of the conveyor through the display.

Alarm device: The alarm device can be an audible alarm, a fiber optic display, an alarm light, etc., which is used to send out an alarm signal when slippage occurs to remind the operator to take appropriate measures.

The installation and use of the belt slip detector should be carried out according to the specific equipment and the instructions provided by the manufacturer. Different detection parameters and thresholds can be selected as needed to achieve real-time monitoring and early warning of the slipping status of the belt conveyor. In this way, problems can be discovered in time and measures can be taken to avoid damage to the equipment and impact on production due to slipping.
