Characteristics of Rubber Belt

 

 

There are a number of characteristics which are the basic factors in differentiating one type of belt from another. For example, if the traction on a conveying system is an issue, it is better to select a deep slotted v-belt. Similarly, sizes play a key role in determining belt configuration. The belt must be wide enough and strong enough to handle heavy load. There are uniquely shaped belts for specialty uses like food processing. Some belts have raised stoppers or blockaded sections which are used to easily sort and package the food. Choosing the proper belt is an important part of using these systems, depending on various uses.

How to Maintain Rubber Belt
 

Regular cleaning and debris removal

Regularly cleaning rubber conveyor belts is crucial to prevent material buildup, which can cause tracking issues and reduce efficiency. A routine cleaning schedule using appropriate cleaning agents helps maintain proper traction and reduces the risk of premature wear.

 

 

Routine inspection for wear and damage

Scheduled inspections allow early detection of wear, tear, and potential damage to the rubber conveyor belts. Promptly addressing issues such as fraying edges, punctures, or worn-out sections helps prevent larger problems and ensures continuous efficient operation.

Proper belt tensioning

Maintaining the correct tension in rubber conveyor belts is essential for optimal performance. Over-tensioning can strain the belt and components, while under-tensioning can lead to slippage. Regularly checking and adjusting belt tension ensures efficient material movement without unnecessary stress on the system.

 

 

Timely repairs and component replacement

Addressing issues promptly with necessary repairs and component replacements is vital. This prevents minor problems from escalating into major breakdowns and maintains the overall efficiency of the material handling system, reducing downtime and associated costs.

How to Choose Rubber Belt

 

 

Assess The Application
Before making any decisions, thoroughly evaluate the application for which the conveyor belt will be used. Consider factors such as load capacity, operating conditions (temperature, moisture, etc.), abrasion resistance, and the type of materials being transported. Understanding these requirements will help you identify the right belt composition and design.

 

Consider Belt Construction
Rubber conveyor belts come in various constructions, including fabric, steel cord, and solid woven belts. Each construction offers different benefits, such as flexibility, strength, and durability. Analyze the specific demands of your application and select the construction that best suits your needs.

 

Evaluate Belt Cover Compounds
The cover compound of a rubber conveyor belt plays a crucial role in its performance. It protects the carcass from wear, impact, and other external factors. Different cover compounds offer varying levels of resistance to oil, chemicals, heat, and flame. Consider the environment in which the belt will operate and choose a cover compound that provides optimal protection.

 

Determine Belt Width And Speed
Proper belt width and speed are essential for efficient material handling. Calculate the required belt width based on the size and quantity of materials being transported. Additionally, take into account the speed at which the belt needs to operate to ensure smooth material flow without any bottlenecks.

 

Pay Attention To Belt Joining Methods
The joining method used to connect the ends of a conveyor belt significantly impacts its performance and longevity. Common joining methods include mechanical fasteners, vulcanization, and cold bonding. Assess the application's requirements, maintenance needs, and overall durability to select the most suitable joining method.

 

Regular Maintenance And Monitoring

Tips for operating a Rubber Belt in extreme cold weather
 

Keep The Belt Moving
If the conveyor system has been designed to meet the needs of the operations, then a good quality rubber belt can typically withstand -30 to -40°c temperatures. However, rubber belts that are made to be fire or oil-resistant aren’t usually able to withstand extremely cold temperatures. In the cold, the rubber begins to lose its elasticity and will eventually become so rigid that it can crack. Friction helps keep the rubber flexible, while a belt that has been left static for a long period of time is more prone to breaking. When a freezing cold snap comes, keep the belt moving as much as possible and avoid frequent shutdowns and start-ups.

 
 

Use Antifreeze And De-icer
Antifreeze prevents ice from forming while a de-icer breaks down ice and snow that has already accumulated. We recommend applying antifreeze to the belt, idlers, and pulleys. However, keep in mind that some operations should not use antifreeze if it poses a risk of contaminating the material.

 
 

Modify An Existing Belt
The need to modify an existing belt is rare if the belt has been engineered for specific operations. However, if a belt has not been designed to meet the conditions of the worksite and issues continue with the belt in extreme weather, then a modification is typically recommended. Simple modifications such as switching to a larger diameter head pulley or going with ceramic lagging can eliminate slippage while protecting the entire system in extreme cold weather conditions.

 
Rubber Belt Joint Method
 

All the conveyor belts must be annular for use, so the quality of the conveyor belt joint directly affects the conveyor belt's service life and the conveyor line's smooth operation. The standard methods of general conveyor belt joints are mechanical joints, cold bonding joints, hot sulfur joints, etc.

Mechanical splice

Generally, it refers to the use of belt buckle joints. This joint method is convenient and economical, but the efficiency of the joint is low and easy to damage, which has a particular impact on the service life of the conveyor belt products. In the pvc and pvg, products are below grade 8. Connecting with a buckle corresponds to 28% -45% of the conveyor belt's strength.

Cold adhesive head

That is, you can use cold adhesive to make the joint. This joint method is higher than the mechanical joint, more economical, and should have a better combined effect. Still, from practice, because the process conditions are more challenging to master, the adhesive's quality significantly impacts the joint; it is enormous and unstable. A cold adhesive bond is equivalent to 40% -55% of the strength of the conveyor belt itself.

Heat-sulfur joints

The practice has proved to be the ideal joint method. It can ensure high joint efficiency but is also very stable. The joint life is long and easy to master. However, there are disadvantages, such as process trouble, high cost, long joint time, etc. Binding with mechanical thermal sulfide is equivalent to 60% -80% of the strength of the conveyor belt itself.
