Laboratory Mills, Grinders and Crushers

For chemical and physical analytical methods such as AAS, NIR, ICP or XRF it is essential that the specimen is perfectly homogenized to an adequate degree of analytical fineness. A reliable and accurate analysis can only be guaranteed by reproducible sample preparation.

For these tasks RETSCH offers a comprehensive range of the most modern mills and crushers for coarse, fine and ultrafine size reduction of almost any material. The choice of grinding tools and accessories ensures that our instruments provide for contamination-free and reliable sample preparation prior to laboratory analysis.

Jaw Crushers

For efficient primary size reduction. The RETSCH Jaw Crusher range is used for the rapid, powerful crushing and pre-crushing of mediumhard, hard, brittle and tough materials. The variety of materials offered, their efficiency and safety make them ideal for sample preparation in laboratories and industrial plants.

Rotor Mills

Fine grinding with variable speed. The rotor mill series includes Ultra Centrifugal Mills, Rotor Beater Mills and Cross Beater Mills. Depending on the particular instrument they are suitable for the preliminary and fine size reduction of soft, fibrous and also hard materials.

Ultra Centrifugal Mill ZM 300 Cyclone Mill Twister

Cutting Mills

For pre-cutting and fine grinding. RETSCH cutting mills provide highly efficient primary size reduction of heterogeneous material mixes but are also suitable for grinding soft, medium-hard, elastic or fibrous samples. Cuttings mills offer a high level of operational safety and convenience. The wide selection of accessories allows for easy adaptation to different application requirements.

Mortar Grinder

The Mortar Grinder RM 200 can mix and homogenize powders, suspension and pastes, even for samples with high viscosity. The RM 200 is suitable for the proper and reproducible sample preparation to analytical fineness. The sample grinder 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.

Sieving

Particle size analysis according to DIN EN ISO 9000 ff. Particle size distribution influences the physical and chemical properties of solids. Therefore this criterion is of highest importance in the context of science and quality control.

Only if the size distribution remains constant, a steady product quality can be guaranteed, as the following examples show:

the strength of concrete depends on the particle size of the cement
the taste of chocolate is influenced by the fineness of the cocoa
the flow characteristics and solubility of washing powders depend on the fineness and particle shape of the basic materials

RETSCH sieve shakers, test sieves and evaluation software provide the key to easy, rapid, reproducible and, above all, accurate analyses.

Sieve Shakers

For particle size determination of bulk materials. RETSCH sieve shakers and sieving machines not only covers a wide measuring range. Thanks to different sieving motions and sieve sizes, the RETSCH sieve shaker range is suitable for almost any bulk material. Our sieve shakers and sieving machines produce exact and reproducible results and comply with the requirements for the test materials monitoring according to DIN EN ISO 9000 ff.

Test Sieves

Highest precision for accurate sieve analysis. The well-proven RETSCH test sieves consist of a solid stainless steel sieve frame of high stability for reliable sieving results. Paying close attention to mesh-specific requirements, the fabric of each test sieve is precisely joined into the frame and tautened. The individual laser engraving of each test sieve provides a clear labeling with full traceability.

White Paper - Different Sieving Methods for a Variety of Applications

The determination and knowledge of the particle size distribution is an essential part of the quality control process for industrial products. Easy handling, low investment cost and high accuracy make sieve analysis one of the most frequently used procedures for measuring the particle size. This white paper gives an overview of the different sieving techniques and describes the necessary steps to ensure reliable results.

White Paper - Cryogenic Preparation of Sample Materials

A solid sample material should always be sufficiently prepared by size reduction and homogenization before it is subjected to chemical or physical analysis. Care should be taken that the analysis sample fully represents the original material and that the sample preparation process is carried out reproducibly. Most sample materials can be reduced to the required analytical fineness at room temperature by choosing a mill with a suitable size reduction principle (impact, pressure, friction, shearing, cutting).

White Paper - How to Minimize Standard Deviations by Correct Sample Preparation

Modern analytical methods increase precision and push detection limits to make even the smallest traces of sample components detectable. Despite this development sample preparation, which is carried out prior to the actual analysis, is frequently neglected. Errors caused by lacking accuracy in sample preparation have a much bigger impact than errors made during analysis.

White Paper - Important Aspects of Sample Preparation of Biological Materials

Biological samples exist in all shapes and sizes: hard bones, tough and fibrous plants, tough and viscous sputum, soft muscles, tumor or liver tissue. Not to mention the millions of cells such as yeast, bacteria or algae, which have to be disrupted for applications such as DNA or RNA isolation or protein extraction. Retsch offers a range of mills and grinders for easy and reproducible pulverization of solid sample materials some of which are also suitable for cell disruption and homogenization of biological sample materials.

White Paper - Reproducible Sample Preparation for Reliable Food Analysis

Food occurs in a great variety of consistencies and is often inhomogeneous. Food testing labs require representative samples to produce meaningful and reproducible analysis results. Therefore, food samples must be homogenized and pulverized to the required analytical fineness, ideally with as little time and effort as possible.

White Paper - Ultrafine Grinding with Laboratory Ball Mills

How are nano particles produced? The “Bottom-Up” method synthesizes particles from atoms or molecules. The “Top-Down” method involves reducing the size of larger particles to nanoscale, for example with laboratory mills. Nano particles are produced by colloidal grinding which involves dispersion of the particles in liquid to neutralize the surface charges. Factors such as energy input and size reduction principle make ball mills the best choice for the production of nanoparticles.
