High-Density Briquetters

Compact Machines for Extreme Density and High-Springback Materials

Logemann’s high-density 2-ram briquetters are purpose-built for materials that resist conventional baling—fine, springy, or difficult scrap streams that demand extreme compression in a compact footprint.

Unlike large-hopper balers designed for volume, these systems utilize a small loading area and staged, high-force compression to produce dense, stable briquettes from materials such as CNC turnings, slitter scrap, tire-derived steel, and fines. The result is a machine optimized for density, containment, and downstream metallurgical value, not bulk throughput.

Designed for High-Springback and Fine Materials

Many briquetters rely on mechanical presses or limited hydraulic force and struggle with springback, inconsistent material, and fines containment. Logemann’s 21-BDS Series is a true two-compression hydraulic baler, combining sequential ram compression, integrated pre-shear for material conditioning, and controlled briquette geometry.

This platform excels where traditional balers fail. Typical materials include:

CNC turnings and milling chips

Aluminum, copper, and brass fines

Slitter scrap and punch scrap

Tire-recycling steel wire

High-springback sheet and trim

Extreme Density in a Compact Footprint

Despite its size, the 21-BDS Series delivers exceptional density performance.

This architecture enables densities typically unattainable in compact machines—while maintaining a footprint suitable for CNC cells, slitting lines, and specialty recycling operations.

Controlled briquette lengths from 3″ to 24″ match downstream handling and furnace charging needs. Cycle times of approximately 60 seconds per briquette provide steady, predictable output without sacrificing compression quality.

Density Matters — Why This Machine Changes the Value Equation

At the foundry, density directly affects yield. Low-density scrap introduces excess air, surface area, and oxidation potential during charging and melting. As density increases, oxidation losses decrease and metal recovery improves along the density-yield curve.

For high-value brass and copper scrap: higher briquette density reduces exposed surface area, lower air entrapment improves melt efficiency, and improved charge behavior increases recovered metal per ton. Achieving up to 50% higher density translates directly into higher foundry yield and higher scrap value, not just better handling. This is the core of Logemann’s Density Matters approach.

Two-stage Compression with Integrated Shear

The 21-BDS design incorporates a first compression ram with reversible shear knives to cut and condition material before final compaction, a second high-force compression ram to achieve final density, and bottom-drop briquette discharge for efficient, repeatable production. This sequence allows the machine to process materials that would otherwise stall, bridge, or spring back in single-stage systems.

High-Density Briquetters

Fines, turnings, high-springback — density drives yield

Small footprint. Maximum density. Measurable yield.

The 21-BDS Series proves that achieving meaningful density—and real foundry value—does not require a massive machine, only the right compression strategy. Density matters. And in this application, it pays.
