Signs Your Pulley Needs Replacing Or Refurbishing

Click here to get more.


A highly loaded piece of rotating equipment such as a conveyor pulley will no doubt experience some level of deterioration over time. 

Engineered conveyor pulleys will eventually start to show signs of wear and will either need to be refurbished or replaced with a new one. Usually, a failing pulley will show a few symptoms that can alert the maintenance team there is an issue and potentially avoid a pulley failure.

Pulley failures can have catastrophic consequences and take extended periods of downtime to repair, so understanding the warning signs is key.

Here we explore some of the most common signs your pulley needs replacing or refurbishing.

Visibly worn pulleys

The first action maintenance teams can take is checking if the pulley passes the eye test. Over time, the pulley and its various components will eventually start to show visible signs of wear, especially those pulleys in harsh environments.

Things to check for include:

  • Visible damage to the end plate, bearing housing, shaft and lagging
  • Material build up on conveyor pulleys (tail pulley/drive pulley/stacker bend pulley)
  • Excessive or uneven wear and deterioration of the lagging
  • Noticeable deflection or noise coming from the pulley
  • Visible cracks on the shaft, especially near a drive coupling or any changes in shaft diameter
  • Damage to locking assembly bolts

Regularly walking the conveyor system to check for damage is good practice for maintenance teams.

Out of square pulleys 

When a pulley is not mounted level and square to the centre line of the conveyor belt it can cause issues such as poor belt tracking and premature pulley or bearing failure and must be resolved. This happens due to various reasons including:

  • Misalignment of take up trolley or guide rollers missing
  • Take up trolley misalignment or obstruction
  • Worn or damaged pulley lagging
  • Worn guide liners

Things to look for:

  • Worn and damaged pulley lagging
  • Missing guide rollers on trolley
  • Visual inspection of the skew on the trolley
  • Take-up trolley doesn&#;t move freely or sticks in spots
  • Worn guide liners on take up pulley
  • Vibration, noise, or heat in the bearing area
  • Build-up of material in lagging

Damaged bearings

Another warning sign that a pulley that needs replacing or refurbishing is a damaged bearing. This can be quite serious and can lead to a range of issues.
Early detection can allow the maintenance team to replace at risk bearings during scheduled downtime and avoid a catastrophic failure.

Damaged bearings often show the following symptoms:

  • Changes in vibration, noise, or heat in the bearing area
  • Contamination in the bearing area
  • Corrosion
  • Uneven resistance
  • Changed lubrication conditions

Pulley lagging issues

Often the most visible signs of deterioration can be found on the pulley lagging. Pulley lagging plays a key role in protecting the pulley and assists in transferring energy from the pulley to the belt.

General wear and tear can occur on the lagging and when left unchecked can cause major issues for the conveyor.

Things to look for:

  • Signs of excessive belt travel and a history of tracking issues
  • Worn out lagging or bulging could mean the lagging has lost adhesion to the shell
  • Rocks caught in lagging
  • Splitting of the shell

10 Things to Consider Before Buying Belt Conveyors

Belt conveyors are a crucial component in many industries, facilitating the efficient movement of materials within a facility.

Choosing the right belt conveyors solutions ensures smooth operations and maximizes productivity.

Before purchasing, factors including capacity, material handling requirements, environmental factors, and safety aspects should be thoroughly evaluated.

What is a Conveyor Belt?

A conveyor belt is an endless loop of material powered by motors and revolves around two or more pulleys. It moves resources and things swiftly and effectively from one location to another.

You will get efficient and thoughtful service from 成钢.

Belt Conveyors are widely utilised in the industrial, distribution, and transportation sectors to move heavy products, food, and parcels. They are adaptable and may be set up to accommodate various requirements, including curves, dips, and inclines.

Conveyor belts aid in process automation, decrease manual labour, and increase productivity across a range of sectors.

Benefits of Belt Conveyor

  • Smooth Material Movement
  • Handles Different Materials
  • Saves Money
  • Saves Space
  • Keeps People Safe

10 Things to Consider Before Buying Belt Conveyor

I. Capacity and Speed Requirements

Before buying a belt conveyors it&#;s crucial to determine the required capacity and speed. This involves assessing the volume of material that needs to be conveyed per hour or day and the speed at which it should move. Consideration should also be given to future growth and scalability, ensuring that the conveyor can accommodate increased production demands

II. Material Handling Needs

Different materials require different conveyor belt solutions. For example, food-grade belts are necessary for conveying food products, while heavy-duty belts are needed for conveying bulk materials such as ores or aggregates. The nature of the materials, such as their size, shape, and weight, should also be considered when choosing a conveyor belt.

III. Conveyor Length and Layout

The layout of your facility and the conveyor path will determine the required conveyor length and configuration. Factors such as bends, inclines, or declines in the conveyor path should be considered to ensure that the conveyor can effectively move materials from one point to another within the facility.

IV. Eco-friendly Factors

The operating environment can greatly impact a conveyor belt&#;s longevity and performance. When selecting a conveyor belt, variables like temperature, humidity, and dust concentrations should be taken into account. It is crucial to choose a belt that is resistant to the environmental factors it will be exposed to.

V. Maintenance and Durability

Selecting a sturdy conveyor belt with low maintenance needs will help cut down on maintenance expenses and downtime. Premium materials, easily replaceable parts, and sturdy construction are traits to look for. When choosing a conveyor belt, take into account the ease of maintenance and the availability of replacing the components.

VI. Belt Conveyors Material

Choosing the appropriate belt conveyors material for your conveyor is essential to guarantee maximum performance and endurance.

Abrasive resistance is crucial because it keeps the belt from wearing out too soon, especially in industries that handle sharp or abrasive materials. Another important consideration is chemical resistance, as prolonged contact with some chemicals can weaken the belt&#;s material. Select a belt material that can tolerate the kinds of pollutants in your surroundings.

Tolerance for severe temperatures is also essential since they can cause the belt material to expand, compress, or become brittle, resulting in an early failure.

VII. Safety Features

Safety should be a top priority when choosing a belt conveyors. Ensure the belt conveyors has safety features such as emergency stop buttons, guards, and safety sensors to protect operators and prevent accidents. Consider safety standards and regulations applicable to your industry to ensure compliance.

VIII. Energy Efficiency

Conveyor belts with low energy consumption can save operational expenses and their influence on the environment. Look for features that can reduce energy use, such as efficient motor systems and variable-speed drives. Consider the long-term financial benefits that energy-efficient conveyor belt systems may provide.

IX. Cost and Budget

When weighing your alternatives for belt conveyors, consider both the upfront cost and ongoing operational expenses. Although it might be alluring to choose the least expensive option up front, it&#;s crucial to consider the conveyor&#;s lifetime total cost of ownership (TCO) and return on investment (ROI).

X. Supplier Reputation and Support

Choose a best supplier with a proven track record in providing conveyor belt solutions. Consider factors such as the supplier&#;s experience, customer support, warranty, and after-sales service. A reliable supplier can provide valuable guidance and support throughout the purchasing process and the conveyor&#;s lifespan.

Conclusion

Choosing the right conveyor belt solutions involves carefully considering factors such as capacity, material handling needs, environmental conditions, safety features, and supplier reputation.

By taking all these key factors into account, you can select a conveyor belt that meets your specific requirements and contributes to the efficiency and productivity of your operations.
