During operation, screw conveyor blade breakage is a serious incident that can disrupt production lines, increase repair costs, and affect business progress. So why do screw conveyor blades break? The causes and solutions in the article below will help you find solutions to improve operational efficiency. Especially if you want to invest effectively, Super One will be a reliable partner you should prioritize.

Common causes of screw conveyor blade breakage

Operating under overload conditions for extended periods.

This is the most common cause. When the amount of material fed exceeds the design capacity, the screw impeller is subjected to continuous high pressure, leading to deformation, cracking, and breakage.

To mitigate this problem, businesses need to control the feed flow and operate the system according to its specifications.

Materials with high abrasion resistance

Materials such as sand, crushed stone, cement, fly ash, or ore have strong abrasive properties. After prolonged use, the screw blades will gradually thin, reducing their load-bearing capacity and making them prone to breakage under heavy loads.

Choosing the right manufacturing material will significantly increase the lifespan of the screw.

Foreign object enters the system

Metal, bolts, large stones, or other hard objects can get stuck between the screw blades and the screw chute. As the shaft continues to rotate, the impact forces will cause the screw blades to bend or break.

Therefore, installing a screen or metal separator before the feeding system is essential.

The quality of workmanship is not guaranteed.

If the screw blades are not machined to standard, the welds are of poor quality, or the materials are substandard, the load-bearing capacity will be significantly reduced. After a period of operation, cracks are likely to appear in these areas, leading to blade breakage.

The screw shaft is off-center.

When the screw shaft is not properly aligned, the screw blades will rub against the conveyor trough during operation. This constant friction not only wears down the blades but also creates significant stress, making them prone to cracking.

Lack of regular maintenance

Failure to inspect the condition of the screw, bearings, bushings, or drive system means that minor damage goes undetected. Over time, these degraded parts will increase the load on the screw and cause problems.

How to fix a broken screw conveyor blade.

To ensure the system operates stably, businesses should implement the following solutions:

• Replace any broken or deformed screw blades immediately.
• Inspect all screw shafts and related components before resuming operation.
• Realign the screw shaft and screw chute for concentricity.
• Control the amount of material fed in to ensure it meets the design capacity.
• Install a foreign object detector or a metal detector.
• Perform regular maintenance and check for wear on the screw blades.
• Use screw blades machined from materials suitable for the working environment.

Understanding why screw conveyor blades break, their causes, and how to fix them will help prevent recurrence and extend the lifespan of the entire system.

Super One – The solution for durable and optimized screw conveyor blade machining for every system.

A high-quality screw conveyor blade not only ensures efficient material transport but also helps minimize problems such as warping, cracking, or wear during operation. Understanding this, Super One focuses on developing custom screw conveyor blade fabrication solutions to meet the stringent technical standards of various industries, including cement, mining, animal feed production, agricultural processing, food, and chemicals.

The value that Super One brings to customers.

Instead of offering mass-produced products, Super One always begins by understanding the customer’s actual needs: the type of material to be transported, system capacity, working conditions, and equipment lifespan requirements. Based on this information, the technical team will advise on the most suitable design, select the appropriate materials and screw impeller structure to ensure long-term efficiency.

Precision machining to order.

Each screw is manufactured based on the technical drawings or actual specifications of the system, facilitating quick installation, minimizing errors, and ensuring stable operation.

Quality control at every stage.

From cutting the blank, shaping the screw blades, welding, adjusting, to checking dimensions, every step is carried out according to a strict quality control process to ensure the product has high durability and stable operation.

Supporting businesses after handover.

In addition to supplying products, Super One also provides technical consulting, installation guidance, system wear assessment, and proposes replacement or upgrade options when necessary. They also answer questions about why screw conveyor blades break, the causes, and solutions, helping businesses minimize risks and optimize maintenance costs.
