RETSCH RM 200 Mortar Grinder

Precision Grinding with the Retsch RM 200 Mortar Grinder

The RETSCH Mortar Grinder RM 200 is the perfect solution for mixing and homogenizing powders, suspensions, and pastes, even those with high viscosity. With its high-performance drive and electronic control, this grinder replaces the need for cumbersome hand mortars.

One of the standout features of the RM 200 is its ability to cool and heat the grinding set, providing the necessary conditions for a wide range of sample preparations. Additionally, the grinding sets are easily exchangeable, allowing for optimum adaptation to tasks.

The grinder operates on the principle of pressure and friction, mixing, and triturating the sample. The scraper ensures that the entire sample is continuously subjected to the grinding and trituration process while being intensively mixed. The offset pestle automatically rotates when in contact with the rotating mortar and the sample. The adjustable spring pressure, combined with the weight of the pestle, provides the necessary grinding pressure.

Pulverizer and the Mortar Grinder RM 200 find applications in a variety of industries. It can be used for grinding ashes, cement clinker, chemical products, coal, cocoa nibs, drugs, food, homeopathic materials, nuts, oil seeds, pharmaceutical materials, plant materials, salts, silicates, slag, soils, spices, tiles, yeast cells, and more.

Pulverizers and Crushers

Some advantages of the product include its ability to perform dry, wet, and cryogenic grinding, ensuring reproducible results with adjustable pestle and scraper pressure. The closed, dust-tight grinding chamber with windows allows for easy monitoring of the process. The mortar and pestle can be easily exchanged without the need for tools, and the load control performance display further enhances ease of use. With a wide range of materials available for contamination-free grinding and three scraper materials to choose from (PU, beech wood, PTFE), the RM 200 offers versatility and adaptability. For high-performance grinding performance, consider the RETSCH ZM 300 Ultra Centrifugal Mill. For an affordable solution ideal for routine grinding applications, the RETSCH SM 100 Cutting Mill is also available.

Invest in the Mortar Grinder RM 200 for reliable, efficient, and precise sample preparation to analytical fineness or the Soil Grinder 220V. With its innovative features and user-friendly design, this grinder is an essential tool for any laboratory or research facility.

The Mortar Grinder RM 200 can mix and homogenize powders, suspension and pastes even with high viscosity. The RM 200 is suitable for the proper and reproducible sample preparation to analytical fineness.  It substitutes cumbersome hand mortars by a high performance drive with electronic control. The grinding set can be cooled and heated and is very easy to clean. Grinding sets of various material qualities are available which can be exchanged easily for optimum adaptation to various grinding tasks.

Function Principle

The RM 200 comminutes, mixes and triturates by pressure and friction. The function of the scraper is to feed the material into the area between the mortar and pestle. This forced feed ensures that the whole of the sample is continuously subjected to the grinding and trituration process and is also intensively mixed. The pestle is not located in the centre of the mortar but is offset; contact with the rotating mortar and the sample causes it to rotate automatically. The necessary grinding pressure is achieved by the weight of the pestle itself combined with the adjustable spring pressure acting on its axis.
