Overview of Hein. Lehmann LIWELL® Separation Technology

The LIWELL® technology from Hein. Lehmann is known for its high-performance screening and separation systems that handle challenging materials requiring precise separation and screening. LIWELL® machines are designed with a dual-frequency screening process, which enhances separation efficiency and addresses issues like clogging and blinding—a valuable feature when dealing with sticky or wet materials common in bulk materials and recycling industries. The unique mechanics of LIWELL® systems reduce blockages by promoting self-cleaning, even when handling fine, wet, or adhesive materials.

Hein. Lehmann markets LIWELL® Separation Technology across a variety of industries, focusing on applications where high accuracy and throughput are essential. The primary market sectors include:

Mining and Quarrying
- Processing of minerals, ores, and stone materials
- Heavy-duty screening for coarse and fine aggregates
Construction and Demolition Waste
- Efficient separation of recyclable materials from construction and demolition waste
Recycling and Bulk Material Handling
- Screening and sorting of metals, wood, glass, and other recyclables
Industrial Processing
- Separation and screening for raw materials in industrial applications, such as chemicals and ceramics

Technical Specifications

1. Dual-Frequency Screening Technology

LIWELL®’s dual-frequency system operates by combining two oscillation frequencies in one screening process. This allows LIWELL® machines to manage challenging materials prone to clogging or blinding, significantly increasing separation efficiency. The oscillation frequencies keep materials in motion, effectively screening sticky or fine particles that may be present in aggregates, ores, or recycling materials.

2. Self-Cleaning Mechanism

The LIWELL® system is designed to self-clean, ensuring continuous operation even when processing wet or adhesive materials. This capability reduces maintenance requirements and operational downtime. The self-cleaning feature is highly advantageous in applications where machines must operate without frequent interruptions due to clogging or build-up.

3. Versatile Screening Media and Configurations

Hein. Lehmann offers customizable screening media for LIWELL® equipment, allowing end-users to adapt the machines to specific applications and material types. Screen configurations and media can be adjusted based on the desired particle size and throughput, making LIWELL® a flexible solution for diverse separation needs across different industries.

Strengths of Hein. Lehmann LIWELL® Separation Technology

1. High Throughput and Separation Efficiency

The LIWELL® separation technology is particularly noted for its high throughput capabilities and ability to handle large volumes of material while maintaining precise separation. This is essential in sectors like mining and recycling, where processing efficiency directly impacts productivity and operational costs.

2. Reduced Clogging and Blockages

Thanks to the dual-frequency oscillation and self-cleaning technology, LIWELL® screens effectively handle materials that would typically cause blockages. In the recycling and bulk material industries, where materials can vary in moisture and adhesiveness, this clogging resistance helps ensure continuous processing and minimizes downtime.

3. Versatile Applications Across Multiple Sectors

LIWELL® technology’s adaptability makes it suitable for use in a wide range of industries. With customizable configurations and screen media, the technology can process different materials, from coarse aggregates in mining to fine metals in recycling.

4. Durability and Low Maintenance Requirements

LIWELL® systems are constructed for durability, handling abrasive and heavy materials without requiring frequent repairs or part replacements. The self-cleaning feature also reduces maintenance needs, a benefit in high-demand operations where prolonged downtime can be costly.

Possible Weaknesses of Hein. Lehmann LIWELL® Separation Technology for Use to Process Organic Wastes

1. The Equipment May Not be Suitable for Organic Waste Processing

Hein. Lehmann does not market LIWELL® Separation Technology for organic waste processing, and this may indicate that the equipment’s design is unsuitable for handling organic material that requires gentle, contaminant-free separation. Unlike depackaging machines, LIWELL® systems do not provide features tailored for organic waste, such as non-shredding mechanisms to minimize microplastic contamination or high-purity organic output.
Absence of Depackaging Capabilities: As far as we can see, LIWELL® technology is not designed to handle packaging materials or to separate packaging from organic material, a core requirement for organic waste depackaging. Depackagers typically need non-shredding separation to prevent microplastic formation, which LIWELL® systems do not offer.

Conclusion

Hein. Lehmann LIWELL® Separation Technology is a specialized solution for industries requiring high-performance material screening and separation, such as mining, recycling, and construction. While Hein. Lehmann LIWELL® technology is versatile within specific industrial sectors, when we reviewed the website, as far as we could determine their products are not marketed for waste processing for materials that are predominantly organic.
