Conveyor belt for wet materials

Conveyor belt for wet materials

Conveyor belt for wet materials is mainly used for pipeline conveying of wet or viscous materials, such as sludge, wet coal, mud, wet materials in food processing, etc. This type of pipeline belt needs to have the characteristics of waterproof, corrosion-resistant, wear-resistant and easy to clean to meet the special requirements of wet material conveying.

What is a conveyor belt for wet materials?

Conveyor belt for wet materials is a belt conveyor system that is water-resistant, corrosion-resistant, and has good structural closure. It is used for continuous conveying of materials with poor fluidity, high viscosity, easy to drip or easy to contaminate. This equipment is specially used for conveying systems of materials with high moisture content (such as wet mud, wet sand, sludge, wet grain, etc.). In industrial applications, it is often used in scenes such as sewage treatment, mine dehydration, food processing, and agricultural waste treatment. Compared with ordinary conveyor belts, they have undergone some special treatments in material and structure to deal with problems such as moisture and adhesion to ensure the effective conveying of materials.

What types of conveyor belt for wet materials are there?

Conveyor belt for wet materials is a special equipment used in industrial production to convey wet, sticky or liquid materials. It is widely used in chemical, food, mining, sewage treatment and other industries. The following are common types of conveyor belt for wet materials:

What is the working principle of the conveyor belt for wet materials?

The working principle of conveyor belt for wet materials is basically the same as that of ordinary belt conveyor. It drives the conveyor belt around the driving roller and the redirecting roller to move by friction, so as to realize the continuous conveying of materials. However, in view of the characteristics of wet materials, the wet material conveyor belt has made some optimizations in material and structure to better adapt to the wet and possible sticky environment.
The driving device such as the motor transmits power to the driving roller through the reducer
The rotation of the driving roller generates friction with the inner surface of the conveyor belt.
Under the action of friction, the conveyor belt starts to move and drives the wet materials above it to move forward together.

Challenges of conveyor belts for wet materials

In many industrial environments, conveyor belts are essential for efficiently moving materials. However, when operating in wet conditions, these conveyor belt systems can face a number of challenges that affect their performance and reliability.

Reduced traction: Wet conditions can cause a significant reduction in traction between the conveyor belt and the drive pulley, which can cause slippage, resulting in reduced productivity and increased wear on the conveyor belt and other components.

Corrosion: Exposure to wet conditions can accelerate corrosion of metal components on wet material conveyor belt systems, weakening the structure and shortening its service life.

Material buildup: Wet material can adhere to the conveyor belt, causing buildup and blockage. This not only reduces the capacity of the conveyor belt, but also increases the risk of damage to the conveyor belt for wet materials and increases downtime for cleanup.

Belt aging: Continued exposure to wet conditions can cause the conveyor belt material to age, resulting in cracks, tears, and other forms of damage, requiring more frequent replacement.

How to deal with problems faced by conveyor belts for wet materials?

Apply a non-slip coating: Applying a non-slip coating to the drive pulley and other contact surfaces can increase traction and reduce slippage in wet conditions.

Choose the right conveyor belt material: Choosing a conveyor belt material that is resistant to moisture and corrosion can significantly improve its performance in wet conditions. Or choose to include rubber belts with special coatings, or synthetic materials designed to resist moisture.

Install a belt cleaning system: Regularly cleaning the conveyor belt can help prevent material buildup and reduce the risk of belt damage, such as scrapers, brushes, and high-pressure water jets.

Improve drainage systems: This can be achieved by installing gutters, drain covers, or shields to protect the conveyor belt for wet materials from rain and other sources of moisture.

Practice preventive maintenance: Regularly inspect and maintain the conveyor system, including checking for signs of corrosion, belt wear, and material buildup, and promptly repairing and replacing them.
