RETSCH DM 200 Disc Mill

RETSCH DM 200 Disc Mill — Accurate, Fast, and Consistent Sample Grinding

The RETSCH DM 200 Disc Mill is a robust grinding solution built for laboratories, pilot plants, and continuous quality control environments. Its sturdy construction delivers precise, reproducible grinding results in just minutes, even under demanding conditions. 

This disc mill is ideal for both coarse and fine grinding of brittle to medium-hard materials. It is widely used in testing facilities that handle minerals, construction materials, environmental samples, and more. 

How It Works

The DM 200 operates on a proven disc milling mechanism. Feed material enters through a filling hopper into a sealed, dust-proof grinding chamber. From there, it is guided between two vertical grinding discs — one fixed and one rotating. 

Pressure and friction between the discs generate comminution forces. Centrifugal action moves the material outward, where preliminary crushing and fine grinding occur. The final ground sample exits through an adjustable gap, which can be set anywhere from 0.1 to 5 mm during operation. 

Versatile Material Applications

The RETSCH DM 200 efficiently processes a wide range of materials, including:

minerals, ores, quartz, cement clinker, coal, slag, gypsum, glass, dried soil samples, construction waste, fibrous materials, grains like corn and wheat, and sintered ceramics. 

This versatility makes it essential for sample preparation in analytical workflows, where repeatable particle size distribution influences the accuracy of downstream testing.

Key Advantages

The DM 200 disc mill offers practical features that improve lab workflows:

• Strong crushing and grinding performance
• Reproducible results through precise gap adjustment
• Hinged grinding chamber for easy cleaning and access
• Long-lasting reversible grinding discs
• Connector for dust extraction systems 

For laboratories requiring additional or complementary grinding solutions, certifiedmtp.com also features products like the RETSCH ZM 300 Ultra Centrifugal Mill for high-speed size reduction of soft to medium-hard materials. 

Complementary Grinding Options

If your application involves cutting, shearing, or size reduction before milling, the RETSCH SM 200 Cutting Mill provides a powerful solution for processing soft, medium-hard, or fibrous samples. 

For other disc milling applications or alternative grinding mechanisms, consider the RETSCH RS 200 Vibratory Disc Mill, which is tailored for high-throughput analytical sample preparation with vibratory action. 

Safe Operation and Maintenance

Operator safety is central to the DM 200’s design. The enclosed chamber reduces dust exposure, while easy access components simplify cleaning and service. Always follow manufacturer guidelines and standard laboratory safety practices when operating or adjusting mill settings.

Regular inspection and replacement of wear parts like grinding discs help maintain consistent performance. Keeping spare parts on hand minimizes downtime and supports continuous operation.

Reliable Choice for Precise Grinding

With its durable build, adjustable parameters, and broad material compatibility, the RETSCH Disc Mill DM 200 delivers reliable, repeatable grinding results for demanding laboratory and pilot plant environments.
