Key Features of a Stripper

The discharge device is an essential piece of equipment in industries that handle powders, granules, or sticky materials. Its primary function is to facilitate the mechanical extraction of stored materials while minimizing the risk of blockages caused by the formation of agglomerates, bridges, or arches inside the silo. By maintaining the flowability of the products, the device directly contributes to the continuity and stability of operations—key factors for quality and productivity.

There are several methods for ensuring a steady flow. Mechanical shearing is one of the primary techniques: rotating blades or paddles break up material bridges and ensure a constant flow toward the discharge screws or feeders. Targeted vibrations are another effective approach, agitating the material to reduce its cohesion and prevent stagnant areas. Finally, compressed air injection is often used to prevent caking and the formation of arches. These methods can be combined depending on the nature of the products and the silo configuration.

The de-caking machine stands out for its great versatility. It is designed to process a wide variety of materials: flour, sugar, salt, plaster, carbonate, silica, plastics, activated carbon, quicklime or slaked lime, and many other powdered or granular products. The typical design includes a rotating shaft equipped with sturdy steel blades, sized to withstand mechanical stress while ensuring uniform flow.

Modern machines, such as our de-stoner and extractor model, also incorporate modular solutions to adapt to different volumes and the specific needs of production lines. The ability to adjust the rotation speed, vibration intensity, or compressed air flow rate provides essential flexibility for improving operational sequences.

The Unloader-Extractor: A Complete Solution for Your Silos and Hoppers

Effective management of bulk materials is essential to the smooth operation of many industrial facilities. Fine, sticky, or low-flow materials can cause blockages and slow down production. We have developed the de-clogger-extractor to address these challenges.

Our discharge unit operates using two complementary systems to ensure optimal flow. A mechanical agitator installed in the cone of the silo or hopper breaks up buildup and facilitates material movement, while an extraction screw ensures a stable and consistent flow to upstream transfer or metering systems. Modular and adaptable, it can be installed on silos, hoppers, or big-bag discharge stations of various sizes to accommodate your production rates and volumes.

In addition, integration with other Transitube equipment—such as conveyors, feeders, and mixing systems—provides comprehensive control over material flow and ensures optimal process consistency. Manufacturers thus benefit from improved product traceability, simplified operations, and a significant reduction in material loss.

Integrated industrial equipment

At TIM Transitube, we offer comprehensive, ready-to-use solutions designed to manage every stage of the process, from storage to machine feeding. Based on Transitube technology (a proven flexible mechanical conveyor), these systems ensure leak-free material transfer, precise metering, and controlled feeding of downstream equipment. Integrated into demanding production lines, they help reduce downtime, stabilize supply, and optimize the use of raw materials.

Flexible screw conveying is at the heart of our material-handling solutions. This conveyor consists of a helical screw driven by a gearmotor that moves products through a flexible, sealed tube. The system transports materials over adjustable distances—including vertical or curved paths—while preventing dust generation and overheating, a key advantage for sensitive or hygroscopic products.

Dosing and Weighing: Precision in Formulation

For many industrial applications, particularly in plastics processing, the quality of the finished product depends on the precision with which each component is dosed prior to processing. We offer volumetric and gravimetric dosing devices capable of meeting this requirement.

Volumetric systems measure and dispense materials (virgin, recycled, or ground products) with a high degree of consistency, generally achieving an accuracy of approximately ±2%, depending on the configuration. These systems can process a single feedstock or multiple components simultaneously, and their adjustable settings allow the dosing to be tailored to different production needs.

Gravimetric weighing systems use weight measurement to ensure maximum accuracy in batch formulation. These systems are often integrated with automated control devices that manage up to nine components and control the entire process via a programmable logic controller. Some configurations meet ATEX requirements and can process batches of up to one metric ton per operation.

It is important to note that our solutions go beyond simple transfer or dosing and ensure the direct feeding of numerous downstream pieces of equipment. Production lines benefit from a constant supply, whether they involve mixers, bagging machines, injection molding machines, extruders, blow molding lines, or micronizers.

Coordination among the various modules (de-slagging, Transitube, feeders, augers, etc.) ensures precise control of material supply and enhances the consistency of operations. This setup reduces the need for manual intervention, which guarantees a consistent supply and improves productivity.

TIM: Expertise in the Plastics Industry

For more than sixty years, Transitube has established itself as a leading player in bulk material handling, thanks to its innovative technologies. Founded in 1961, the group experienced significant industrial growth with the development of the flexible spiral, a mechanical feeder capable of moving powders, granules, and fragile materials without the risk of compaction or overheating. This innovation has optimized material transfer processes across a variety of sectors, including food processing, chemicals, pharmaceuticals, construction materials, and plastics manufacturing.

The Transitube operates using a flexible screw that rotates inside a flexible tube. This system generates a helical motion that conveys materials smoothly, preserves their quality, minimizes dust formation, and ensures quiet operation. Its modular design allows for the creation of complex conveyance paths, including vertical or curved sections, without requiring major modifications to the industrial layout. This flexibility facilitates integration into existing or new facilities, offering manufacturers a reliable and high-performance solution for the efficient transfer of bulk materials.

TIM Transitube, a specialized unit of the Transitube Group, has developed recognized expertise in the field of plastics processing since 1971. We have focused on applications related to plastics processing, covering the preparation, transfer, metering, and feeding of raw materials to production machinery, including extruders, blow molding machines, presses, mixers, and rotomolding lines.

Thanks to our in-depth understanding of the specific challenges in this sector—such as variations in density, hygroscopicity, thermal sensitivity, and a tendency to clog—we have been able to design solutions that are not only robust but also perfectly tailored to the needs of manufacturers.

Building on our years of experience and numerous successful projects, we have expanded our business far beyond the domestic market, becoming a global partner for companies seeking to integrate high-performance Transitube systems.

This certification offers several operational advantages: it minimizes the risk of accidents caused by dust ignition or explosions. It ensures that facilities strictly comply with current standards in sensitive industries and provides the long-term reliability that is essential for production lines operating continuously.

To help manufacturers effectively implement our de-burring machine into their processes, we offer a structured, three-step approach:

• Audit and Consulting

Before any system is put into service, the technical teams conduct a thorough analysis of the site. The study examines the capacity of silos and hoppers, the nature of the materials being handled (powders, granules, sticky or abrasive materials), the required flow rates, and any process-specific constraints. The audit enables us to accurately size the equipment, identify critical points in the material flow, and define an optimized solution that fully meets production needs.

• Installation and Commissioning

Once the parameters have been set, installing the discharge device is very straightforward, even on existing silos or hoppers. The components are put in place and then calibrated to ensure optimal material flow based on the site’s specific characteristics.

Our experts also handle the technical integration with existing systems: dosing units, conveyors, control systems, ATEX-compliant solutions, and more. This step ensures that all components operate consistently, safely, and efficiently from the moment they are commissioned.

• Training and Support

To ensure the sustainable and optimal operation of the equipment, we offer a comprehensive operator training program covering daily use, fine-tuning, and best practices for material handling. A preventive and corrective maintenance service is also available to anticipate wear and tear, avoid unplanned downtime, and maintain original performance levels. Finally, we provide ongoing technical support, available to quickly address any questions or adjustment needs.

Many manufacturers have seen tangible benefits after adopting our de-clogger. By ensuring a steady flow of bulk materials—even those that are difficult to handle or slightly damp—the equipment eliminates interruptions caused by blockages and stabilizes the flow to downstream machines.

In addition, the unloader helps maximize the value of recycled materials and reduce waste, thereby optimizing resource use and operational costs. Its reliability minimizes the need for human intervention and ensures the safety of facilities, even in demanding industrial environments.
