NEXOPART Particle Analysis
NEXOPART is a new particle analysis brand, created by two well-known German companies: Haver & Boecker and Hosokawa Alpine. Together, they bring over 80 years of experience making test sieves, plus more than 60 years of expertise in air-jet sieving technology.
Traditional particle analysis has been a fixed part of Haver & Boecker for over 80 years. In the sector of Dynamic Image Analysis with the HAVER CPA, Haver & Boecker is one of the founders of this product category and now has over 20 years of production innovation and experience.
Sieve Analysis
Sieve analysis is a classic, reliable method to measure particle size. NEXOPART offers a wide range of test sieves and sieve shakers, built to international standards, to help you test almost any material — from powders and granules to minerals and food.
Standards
As measuring instruments, test sieves are subject to the high quality requirements defined in national and international standards. Haver & Boecker offers test sieves with wire mesh, which are in accordance with all common standards: DIN ISO 3310-1, ISO 3310-1, ASTM E11, BS ISO 3310-1. Test sieves with perforated plates in accordance with DIN ISO 3310-2, ISO 3310-2, BS ISO 3310-2. Test sieves with electroformed sieve foil in accordance with DIN ISO 3310-3, ASTM E 161 and ISO 3310-3.
Sieving methods
Haver test sieves are suitable for all common sieving methods: horizontal sieving, three-dimensional sieving, dry and wet sieving, air jet sieving and manual sieving. Haver & Boecker offers a multitude of test sieve shakers and systems for a wide variety of applications and systems, which can be precisely matched to suit special requirements.
Sample division
Sample division is necessary in order to obtain a representative test quantity. The classic method of sample division involves dividing the entire amount of material by quartering the original quantity. In order to simplify the process, Haver & Boecker offers different types of sample splitters as well as rotary sample dividers to obtain particularly precise test quantities.
Analysis
Once the representative material samples are available and the appropriate test sieves have been determined, the analysis can be carried out with a sieve shaker. Haver & Boecker test sieve shakers generate a three-dimensional sieving motion for fast and optimally reproducible sieving results. The material to be sieved is accelerated vertically out of the mesh and at the same time distributed over the surface of the sieve in a circular motion. The amplitude is regulated automatically and remains constant, irrespective of the quantity and the installation location.
Evaluation
The HAVER CSA software enables PC-aided evaluation of standard sieve analyses. Analyses can thus be evaluated easily and precisely within a short amount time. Data is generated quickly and easily using a HAVER scanning system for the test sieves. The results, graphical representations and documentation materials can be documented for quality assurance purposes and incorporated in statistics and reports.
Cleaning
Clean test sieves are prerequisite for flawless and reproducible sieving results. Near-mesh particles, which are trapped in the sieve mesh, can be removed by tapping the sieve. Ultrasonic cleaning devices ensure thorough, gentle and energy-saving sieve cleaning. Cleaning with brushes or bristles is not recommended.
