In the world of material handling and processing, the Spiroflow Flexible Screw Conveyor (FSC) has long been a trusted solution for conveying challenging and non-free-flowing products. However, the standard agitator design used in the FSC has posed challenges when it comes to cleaning and maintenance.

Now, a breakthrough innovation has emerged—a newly designed Flexible Screw Conveyor Agitator that can be easily removed for cleaning in place. This article delves into the features, benefits, and significance of this game-changing agitator design.

The Need for Flexible Screw Conveyor Agitators

The Spiroflow FSC has been a workhorse in various industries, efficiently conveying a wide range of products. However, many materials encountered in processing are not free-flowing, leading to issues like bridging and material flow disruptions. To address this problem, agitators are essential in breaking up bridging materials and promoting consistent product flow within the conveyor.

Limitations of the Standard Agitator Design

For over two decades, Spiroflow’s standard agitator design served its purpose, but it came with certain limitations. The removal process required tool intervention, making it time-consuming and potentially hazardous for operators. This traditional approach led to production downtime and increased maintenance costs.

Introducing the New Flexible Screw Conveyor Agitator

The newly designed Flexible Screw Conveyor Agitator represents a significant advancement in material handling technology. The key highlight of this innovation is its easy disassembly feature, allowing operators to clean it safely without the need for tools. This enhanced accessibility is made possible through the integration of safety interlocks to protect all channels and the ability to leave the gearbox and motor in place during disassembly.

Benefits of the New Agitator Design

  1. Streamlined Cleaning Process: The new agitator design allows operators to quickly disassemble and reassemble the unit on-site, simplifying the cleaning process and reducing downtime. With no plugs and sockets required, the risk of misplacement or damage during reassembly is eliminated.
  2. Enhanced Safety: The incorporation of safety interlocks ensures that operators can handle the disassembly process without compromising their safety. This feature prevents accidental starts and disassembly while the equipment is still operational.
  3. Versatility: The flexible screw conveying agitator can be retrofitted to existing machines, providing a cost-effective solution to replace the current standard agitator unit. This versatility allows businesses to upgrade their systems without investing in entirely new equipment.
  4. Improved Material Flow: By breaking up bridging material at the flexible screw inlet, the agitator optimizes material flow within the equipment, leading to a smoother and more efficient conveying process.
  5. Time and Cost Savings: The easy removal and cleaning capability of the new agitator design significantly reduce maintenance costs and minimize production downtime. This leads to improved overall operational efficiency and increased productivity.
