How to solve the quality problem of cement silo in cement clinker production line
Advanced homogenization and unloading equipment series for cement silos, highlighting innovation in material handling processes.

1、Project Overview

The cement silo for a clinker production line began operation in 2007. It features a reinforced concrete circular structure with a height of 61.81 m and an inner diameter of 22.5 m. The silo wall is 380 mm thick and reinforced with non-prestressed steel bars. The concrete strength is designed to be C30.

After the silo started operation, inspections found multiple vertical and circumferential cracks on its outer surface. These cracks appeared mainly between elevations +14.166 m and +50 m.Some cracks exceeded 0.2 mm in width, violating specifications. Inspectors also found hollow areas and peeling concrete on the silo wall. Consequently, the owner required technical reinforcement for the cement silo.

The yellow cement silo stands tall, featuring large loading ports and serving as a key storage unit in the cement production process.

2. Analysis of the cause of the accident

Upon discovering the cracks, the owner commissioned a testing agency to evaluate the silo wall's concrete strength, reinforcement, and cracks. The tests showed that the concrete strength generally met design requirements. However, the annular reinforcement from +14.166 m to +50.000 m mostly did not meet specifications. The crack widths between +23.5 m and +34.2 m also fell short of requirements.

The inspection revealed that vertical cracks resulted from stress and temperature effects on the wall. Circumferential cracks occurred due to insufficient reinforcement and poor joint connections. The team constructed the raw material homogenization silo using a slipform process. This method created tied and overlapped horizontal reinforcement joints. It did not use welded connections.The protective layer around the reinforcement was too thin. This weakened the bond between the reinforcement and the concrete.

3. Reinforcement treatment（Scheme selection）

We considered two solutions for reinforcing the raw material homogenization silo. One solution involves reinforcing the outer wall with concrete. The other solution applies external prestressing. Below is a comparison of both methods.

 

3.1.1 Use reinforced concrete to increase the cross-section of the cylinder wall

This method involves adding 200 mm of reinforced concrete to increase the cross-section of the cylinder wall from the foundation ring beam to +50 m. This solution would require reverse mold construction and take about six months to complete. Since the silo operates during this time, the long construction period is a drawback. Additionally, the new structure may not fully integrate with the existing steel bars, reducing material efficiency. The estimated cost for this method is around 2 million yuan, making it less favorable in terms of effectiveness and cost.

3.1.2 External prestressing reinforcement

Cracks mainly arise from inadequate circumferential reinforcement and temperature stress. We can place steel strands along the outer surface in the circumferential direction. Applying external prestressing will help the internal circumferential reinforcement and external strands work together.

Since the silo is currently in use, this method can effectively reinforce the structure and potentially close some cracks. The estimated cost for this project is about 1 million yuan.

 

Conclusion

Considering the reinforcement effectiveness, cost, and site conditions, we determined that the external prestressing method is the most reasonable and economical solution for this silo.

Belt Conveyors: Efficient Solutions for Material Handling

What is a Belt Conveyor?

A belt conveyor is a system designed to transport physical items such as materials, goods, and even people from one point to another. Unlike other conveying methods that use chains, spirals, or hydraulics, belt conveyors rely on a continuous belt to move items efficiently.

Components of  belt conveyors

A standard belt conveyor system has a head pulley, tail pulley, idler rollers, belt, and frame.

Head Pulley

The head pulley connects directly to the actuator and electric motor, driving the conveyor and generating the necessary pulling force. Located at the discharge end, it efficiently offloads materials. To enhance traction, the head pulley often features a rough jacket, known as a legging, covering its outer surface. Typically, the head pulley boasts the largest diameter among all pulleys in the system. While some systems may include multiple drive pulleys, you will usually identify the one at the discharge end as the head pulley.

Return or Tail Pulley

The return or tail pulleys are positioned at the loading ends of the belt conveyors.Often, it features a wing shape that facilitates cleaning by allowing material to fall away to the support members. In simple setups, the tail pulley mounts on guides, which adjust the belt’s tension. Conversely, in more complex systems, a separate roller known as the take-up roller manages this tension effectively.

Idler Roller

Idler rollers run along the length of the belt, providing crucial support for both the belt and its load. They play a vital role in preventing sagging, ensuring proper alignment, and helping to clean up carryback—material that tends to stick to the belt. Whether they perform all these functions or just one, idler rollers consistently deliver essential support for the belt’s operation.

Troughing Idlers

Troughing idlers feature three rollers arranged to form a “trough” shape for the belt. These idlers sit on the side that carries the load. Specifically, the center idler stays fixed, while the two end idlers can adjust to vary the angle and depth of the trough. As a result, this adjustment enhances the conveyor's efficiency in handling materials.

Benefits of Using Conveyor Belt Systems

Conveyor belt systems act as essential mechanical devices that provide numerous benefits. First, they offer affordability, making them a cost-effective choice for many businesses. Additionally, their ease of use simplifies operations, allowing employees to handle materials efficiently. Moreover, these systems demonstrate versatility by effectively managing a wide range of items, from small objects to large industrial products. Consequently, businesses can streamline their material handling processes and improve overall productivity.

Here are some key benefits:

  • Large transmission flow rate
  • Very low energy requirements
  • Low investment and service costs
  • Stable and trouble-free transportation of products
  • Easy operation
  • Reduced manpower and increased productivity
  • Continuous operation
  • By integrating a belt conveyor system, businesses can streamline operations and enhance efficiency in material handling.

enhancing-bulk-loader-with-self-locking-device-to-prevent-material-scattering-and-ensure-optimal-functionality

The Challenge of Material Scattering

During our on-site surveys, we found a significant issue: after loading, the telescopic sleeve often retracts and causes materials to scatter. This scattering leads to material loss, increases pollution, and poses safety risks.

 

Introducing the Self-Locking Device

To address this challenge, we developed a self-locking device. This innovation effectively prevents remaining materials from scattering when the discharge head cycles back after unloading.

 

Benefits of the Self-Locking Device

The self-locking device securely holds the remaining materials at the exit or loading area of the bulk loader. This stability reduces material loss and enhances overall functionality.

 

Conclusion

By incorporating the self-locking device, we significantly enhance the performance of the bottom-discharge bulk loader. This improvement not only protects materials but also creates a safer and cleaner working environment. For high-quality bulk handling solutions, consider partnering with Darko, where we are committed to providing innovative equipment and exceptional service to meet your operational needs.
