Particle size, particle size distribution, and homogeneity influence numerous properties of powders and granules. Accordingly, laboratories place great emphasis on the careful preparation of raw materials and product samples. Grinding, pre-mixing, and particle size analysis are among the routine steps that precede many development and quality control tasks.
New raw materials, modified formulations, or adjusted process parameters are typically evaluated in the laboratory before being introduced into production. To ensure comparable results, materials must be prepared under defined conditions. Variations in particle size or uneven distribution of individual components can significantly affect the assessment of material and product properties.
FUCHS Maschinen AG, based in Granges-Paccot, Switzerland, develops and manufactures equipment for the processing of powders, granules, and other free-flowing bulk materials.
Its product range includes solutions for grinding, mixing, and particle size distribution analysis through sieving. The systems are used in laboratories, R&D departments, and quality assurance applications.
Defined Particle Sizes as a Basis for Testing
Many raw materials are supplied in varying particle or granule sizes. Prior to further testing, materials are therefore often reduced to a defined particle size.
For this purpose, the GRANOMAT JP grinding system can be used for a wide range of materials. The processed product then serves as the basis for mixing trials, particle size analyses, and additional laboratory investigations. Consistent starting conditions are particularly important in raw material evaluations, product development projects, and comparative studies.
Pre-Mixing for Development and Quality Control
Laboratories frequently process small material quantities. New formulations, raw material combinations, and product variants are typically evaluated on a laboratory scale before further development.
The MIXOMAT MINI was developed specifically for such applications. It is suitable for the preparation of pre-mixes and small laboratory batches.
In addition, the MIXOMAT A is used for mixing tasks in laboratories, development departments, and quality assurance. Powders and granules can be homogenized and prepared for further testing.
Particularly in comparative studies or formulation optimization projects, multiple blend variants are often evaluated under identical conditions. Achieving a uniform distribution of all components is therefore essential.
Determining Particle Size Distributions
Particle size distribution is one of the key parameters routinely measured for powders and granules. It is considered during raw material inspection, product development, and quality control processes.
With the SIFTOMAT MINI, FUCHS Maschinen AG offers a compact sieving system for laboratory and testing applications. The system is used both for determining particle size distributions and for separating different particle fractions.
The resulting data supports the comparison of raw materials, intermediate products, and finished products and complements other laboratory analyses.
From Material Preparation to Quality Control
The preparation of powders and granules is a routine task in laboratories across the pharmaceutical, food, and chemical industries. Grinding, mixing, and particle size analysis provide the basis for reproducible testing procedures and reliable results.
With the GRANOMAT JP, MIXOMAT MINI, MIXOMAT A, and SIFTOMAT MINI, FUCHS Maschinen AG offers equipment covering the key stages of sample preparation—from material conditioning and pre-mixing to particle size distribution analysis.
