Limbă:

The microprocessor-controlled measuring and control unit of this model ensures a constant vibration height, allowing for 100% reproducibility of results even among different AS 200 control shakers. One particular characteristic makes this RETSCH product stand out from others: Instead of the vibration height, it is possible to set the sieve acceleration which is independent of the power frequency. Together with the possibility of calibration, this ensures comparable and reproducible sieving results worldwide. Thus, all requirements for the test materials monitoring according to DIN EN ISO 9001 are met.

All sieving parameters – vibration height, time, and interval – are set, displayed and monitored digitally which makes operation of the AS 200 control very convenient and quick. Up to 99 standard operating procedures (SOPs) may be stored for routine analyses.

Through the integrated interface the instrument can be connected to a PC and controlled with the evaluation software EasySieve®. This program enables the user to carry out the whole sieving process and its subsequent documentation with convenience, accuracy and conforming to standards.

Maşină de sitat vibratoare AS 200 control Sitare umedă

Există numeroase aplicații pentru care sitarea umedă este cea mai bună soluție, ca de exemplu atunci când materialul se află intr-o suspensie sau atunci când proba este foarte fină (< 45 μm) și tinde să se aglomereze. Toate mașinile de sitat vibrante RETSCH pot fi folosite pentru sitare umedă. Pentru aceasta sunt disponibile accesorii speciale ca, dispozitive de prindere și colectoare. Prin montarea unor inele de ventilare între site, pernele de aer se pot extinde fără a pierde lichid sau probă.

Software de Evaluare EasySieve / EasySieve CFR

EasySieve, the software for particle size analyses, exceeds manual evaluation in many aspects. The software is able to automatically control the necessary measurement and weighing procedures – from the registration of the weight of the sieve up to the evaluation of the data. It is simple and convenient to use and is also available in an FDA 21 CFR Part 11-conform version.

Efficient Separation of Stones from up to 9 Soil Samples with the AS 200 control

In soil analysis, sieving with the AS 200 control prevents distortion of analytical results, reliably separates rocks from soil samples, and simultaneously minimizes equipment damage. Users achieve time-saving and precise analytical results, while maximizing the service life of their devices.

Unbeatable Together: The AS 200 control in combination with the BB 50 jaw crusher is the proven solution for processing large agglomerates from soil samples and can handle up to nine samples in one batch.

After

A 120 g soil sample with agglomerates up to 15 mm in diameter was processed using a 200 x 25 mm sieve with 2 mm round holes.

Application at Cologne Cathedral – Optimal Protection for Historical Stone Surfaces

The Cologne Cathedral workshop has relied on the AS 200 control for many years to precisely determine particle size distribution in mortar. Various particle fractions can be accurately separated and combined. The goal is to develop mortar with optimal structure and color that almost perfectly replicates the original stone. The use of the AS 200 control eliminates manual sorting, making mortar production more reproducible and efficient.

The result: mortar with the physical properties to fill cracks and simultaneously prevent water penetration.

Highest Food Quality with the AS 200 control

At Lebensgarten GmbH, the quality of organic cereal flakes is ensured through precise incoming goods inspections. Sieving analysis separates the flakes into different particle size fractions. Special importance is given to the dust fraction of the product with a particle size < 500 μm. This can impair the sealing of packaging on the one hand and negatively affect the consistency of crunchy products on the other.

The patented electromagnetic drive and the three-dimensional throwing motion of the AS 200 control ensure even distribution and optimal separation. Thanks to flexibly adjustable parameters such as amplitude and hole size, various types of flakes can be precisely sieved – ideal for checking raw material quality regarding dust and fine fractions and ensuring high quality in end products.
