Bucket Elevator Belts 101: An Inside Look at Belt Manufacturing

Bucket elevators are conveyor systems designed to vertically transport bulk materials. They consist of a series of buckets attached to a belt or chain that circulates around drive and idler pulleys or sprockets.

The main purpose of bucket elevators is to efficiently lift bulk materials vertically with minimal product degradation. They are commonly used to transport granular, free-flowing materials like grains, seeds, pellets, powders, etc.

Some common industries that utilize bucket elevators include:

  • Agriculture – for moving grain, soybeans, seeds, etc.
  • Food processing – for moving flour, sugar, coffee beans, etc.
  • Mining – for moving ores, minerals, aggregates etc.
  • Chemicals – for moving powders, pellets and granules.

The main components of a bucket elevator system are:

  • Buckets – to contain the material being lifted. Usually made of steel or plastic.
  • Belt/Chain – circulates the buckets and transfers drive power. Often rubber or plastic belts.
  • Casing – encloses the belt and buckets to contain dust and debris.
  • Drive unit – provides power to turn the belt/chain. Typically an electric motor & gearbox.
  • Take-up device – provides proper tensioning of the belt/chain.
  • Head section – guides the material into the buckets at the bottom.
  • Discharge chute – guides the material out of the buckets at the top.
  • Bearings – allow the pulleys to turn freely.
  • Access doors – allow inspection and maintenance access.

Bucket elevators provide an efficient way to lift bulk materials vertically with minimal product breakage. Their simple design and ease of maintenance makes them a staple across many industries.

Bucket Elevator Belts

Bucket elevator belts are a critical component that makes these conveyor systems work efficiently to move bulk materials vertically. Choosing the right belt is important to maximize uptime and throughput. There are several key factors to consider when selecting a bucket elevator belt:


Bucket elevator belts are typically constructed using various rubber compounds or PVC. Rubber belts are more durable and have better abrasion resistance. Common materials include natural rubber, styrene butadiene rubber (SBR), and neoprene. PVC belts are lighter and more affordable, but cannot handle as much load or wear as well as rubber.

Rubber belts are preferred for heavy-duty bucket elevators moving abrasive materials like grain, while PVC works for lighter loads. The belt’s carcass or reinforcement is also important. Options include nylon, polyester, steel cable, steel mesh, etc. This impacts strength and dimensional stability.

Key Properties

Tensile strength, elongation, and adhesion are vital properties in a bucket elevator belt. Belts must have high tensile strength to carry heavy loads without stretching or breaking. Elongation allows for some flexibility to grip buckets and absorb impacts. Proper adhesion ensures the belt cover remains bonded to the carcass.

Temperature resistance is another consideration for environments that may experience heat. Oil or flame resistance may also be required. The belt surface needs good abrasion and cut resistance. Having the right traction is also important to properly run on pulleys.

Belt Types

Common bucket elevator belt types include:

  • Multiply Belts: Multiple layers of rubber and fabric provide high strength for heavy loads.
  • Solid Woven Belts: One-piece homogeneous construction without joints. Excellent for abrasive materials.
  • Steel Cable Belts: With steel cable reinforcement for extra durability and bucket control.
  • PVC Belts: Lightweight and economical but lower performance than rubber belts.
  • Endless Belts: Made continuous without splices for uninterrupted operation.

Multiply and solid woven rubber belts offer the best performance, but have higher cost. PVC and steel cable belts provide more budget-friendly options. It’s important to match the belt to the specific application and load requirements. Consulting a qualified belt supplier is recommended to ensure optimal selection.

Choosing the Right Bucket Elevator Belt

When selecting a bucket elevator belt, it’s important to consider several factors to ensure you choose the optimal belt for your specific application and operating conditions. The belt is a critical component that greatly impacts the performance and longevity of the entire bucket elevator system.

Key Factors to Consider

  • Belt Strength – The belt must have sufficient strength for the capacity and torque requirements of your elevator. Consider the belt’s tensile strength, adhesion between plies, and resistance to flex fatigue. Stronger belts with multiple plies are required for heavy loads.
  • Belt Type – Common options include PVC, rubber, urethane, silicone, and stainless steel. PVC is economical but has limited chemical resistance. Rubber offers high abrasion resistance. Urethane has excellent wear life. Silicone withstands high temperatures. Stainless steel is very strong but expensive.
  • Operating Conditions – Factors like temperature, exposure to oil or chemicals, and cleanliness of the material being conveyed determine what belt type will perform best. Consider abrasion and corrosion resistance needed.
  • Bucket Spacing – Make sure the belt has the right flexibility and troughability to properly match your bucket spacing and elevator configuration.
  • Compliance – Choose belts that meet safety codes and standards for your industry and application.

Importance of Proper Sizing

  • Accurate sizing of the belt length, width, and thickness is crucial. Undersized belts will stretch, deform, and wear out more quickly.
  • Oversized belts run less efficiently and can experience tracking problems. Consult your supplier’s engineering recommendations.
  • Leave sufficient clearance between buckets and casing to prevent jamming but minimize slack.

Maintenance Matters

  • Regular inspection and proactive maintenance extends the usable life of your belt.
  • Check for signs of wear, damage, or looseness. Clean off any material buildup.
  • Proper storage and handling prevents unnecessary belt damage when not in use.
  • Replacement before failure prevents unexpected downtime and safety issues.

Choosing the optimal bucket elevator belt and following good maintenance practices ensures reliable conveying with lower operating costs over the long run. Consult a qualified belt supplier to match a belt to your specific application.

Bucket Elevator Belt Suppliers

Bucket elevators are used in a wide range of industries to efficiently move bulk materials vertically. The bucket elevator belt is a critical component that greatly impacts performance and longevity. When selecting a new or replacement belt, partnering with the right supplier is key. Here’s an overview of major suppliers in the market and what to look for when choosing one:

The elevator belt supply market is dominated by several large, multinational corporations like Continental, Ammeraal Beltech, and Intralox. These established players offer a wide selection of belts and materials. They leverage economies of scale to keep costs down. However, their belts are mass-produced to fit common elevator designs. For non-standard elevators or specialty applications, a smaller, niche supplier may be a better option.

Specialized bucket elevator suppliers focus entirely on engineering belts for unique requirements. They work closely with customers to custom-design belts based on specific material properties, elevator dimensions, capacity needs, and operating conditions. This customization results in a belt that maximizes elevator performance and reliability. Niche suppliers also offer superior customer service, technical support, and industry expertise.

When evaluating suppliers, here are key factors to consider:

  • Technical capabilities – Do they have engineering expertise? Can they design custom belts? What materials and coatings do they offer?
  • Manufacturing quality – Where are their belts produced? What quality control procedures do they follow?
  • Industry experience – How long have they been in business? Do they specialize in bucket elevators?
  • Customer service – Will they provide support during selection, after sales, and for troubleshooting?
  • Cost – Get quotes from multiple suppliers. Weigh value against price.

While large corporations can meet common needs, partnering with a niche supplier offers advantages like custom engineering, specialized knowledge, and attentive customer service. For unique bucket elevator applications, a specialized belt supplier is often the best fit.

Working with a Belt Supplier

Choosing the right bucket elevator belt supplier is crucial for ensuring you get high-quality products tailored to your specific application. The supplier you select should provide expertise and support beyond just supplying elevator belts. Here are some tips on working with a belt supplier:
