What is analytical sieve shaker?
The analytical sieve shakers of the series AS 200 are used in research & development, quality control of raw materials, interim and finished products as well as in production monitoring. Sharp fractions are obtained even after short sieving times.
What is the practical significance of Rotap sieve shaker?
Using a sieve shaker decreases the time it takes to perform a sieve analysis. This allows you to not only perform and analyze results faster, but also allows you to complete more tests each day. Sieving by hand requires more time and more diligence in your process to ensure accurate results.
What is Rotap sieve shaker?
Ro-Tap Sieve Shakers is a sieving machine that is widely accepted in standardized particle sizing test methods. These shakers have a horizontal, circular motion with a vertical tapping action to assure accurate and consistent particle analysis testing results.
What is size separation?
Size separation is a unit operation that involves the separation of a mixture of various size particles into two or more portions by means of screening surfaces. Size separation is also known as sieving, sifting, screening.
Is sieve A analysis?
A sieve analysis is an analytical technique used to determine the particle size distribution of a granular material with macroscopic granular sizes. The sieve analysis technique involves several layers of sieves with different grades of sieve opening sizes.
What is mechanical shaker?
The uses of a mechanical sieve shaker include determining the range of particle sizes within a sample. Depending on the model of shaker, wet and dry samples can be analyzed using touch screen controls and software applications.
What is oversize and undersize particles?
0 The material that passes through a given screen/screening surface is called the undersize or minus (-) material while the material that remains on the screen/screening surface is called the oversize or plus (+) material. A single screen can make a single separation of the material charged into two fractions.
What is the function of the shaker?
A shaker is a piece of laboratory equipment used to mix, blend, or agitate substances in a tube or flask by shaking them. It is mainly used in the fields of chemistry and biology. A shaker contains an oscillating board that is used to place the flasks, beakers, or test tubes.
How does a Rotap work?
Basically, the machine holds a stack of sieves and then shakes the stack so that the material falls down through all the sieves and gets stuck at each different size opening. The machine was created to get consistent, repeatable results that are more reproducible than hand sieving.
What is Rotap?
A RO-TAP is a particle analysis machine that is used in all kinds of industries to test and separate particles. An oscillating motion is used to shake particles down through a series of different test sieves in a stack.
What are the standard sieve sizes?
Particle Size Conversion
| Sieve Designation | Nominal Sieve Opening | |
|---|---|---|
| Standard | Mesh | Inches |
| 6.35mm | 1/4 in. | 0.250 |
| 5.66mm | No. 3 1/2 | 0.223 |
| 4.76mm | No. 4 | 0.187 |
When to use an analytical sieve shaker as 200?
The analytical sieve shakers of the series AS 200 are used in research & development, quality control of raw materials, interim and finished products as well as in production monitoring. The controllable electromagnetic drive offers an optimal adaption for every product. Sharp fractions are obtained even after short sieving times.
What kind of sieve shaker does Retsch use?
The AS 200 basic sieve shaker is the economical alternative of the series with familiar RETSCH quality and reliability. It features digital setting and display of performance and time.
What are the benefits of using Retsch test sieves?
In addition to the requirements laid down by the standard, RETSCH test sieves offer significant benefits: The unique manufacturing process of RETSCH test sieves with a one-piece stainless steel sieve frame guarantees unrivaled stability and consistency for your sieving application.
When to use chain rings in a sieve shaker?
Chain rings, brushes, cubes, balls (e.g. for reducing agglomerations when sieving particles < 100 μm and keeping the mesh free). We provide IQ/OQ documentation for the „control“ sieve shakers to support IQ/OQ certification by our customers. Meaningful results can only be obtained if the sample represents the original material.
