What is Rotap sieve shaker?
This Shaker reproduces both circular and tapping motion, Produces Circular (280-320 RPM approx) and tapping (140-160 RPM approx) motion with a uniform mechanical action which ensures accurate and dependable test results. This shaker is heavy in construction and no special foundation is required.
What is a 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 is the sieve analysis test?
A sieve analysis or gradation test determines the distribution of aggregate particles by size within a given sample. This information can then be used to determine compliance with design and production requirements.
How long do I run my sieve shaker for?
Select an initial test time, usually 3-5 minutes, and run a sieve analysis. Record the amount of sample retained (or passed, if that is the result typically recorded) on each sieve. Using the same sieves and sample, run the test again incrementally longer, usually adding 1-5 minutes to the initial test time.
What is the disadvantage of the sieve shaker method?
Disadvantages. It is practically impossible to measure sprays or emulsions and cohesive and agglomerated materials such as clays. Standard sieves range from 38 μm to 4.75 mm (0.187 in.). The method is usually labor intensive.

What is D10 in sieve analysis?
D10 is called as effective particle size. This means that 10% percent of the particles are finer and 90% of the particles are coarser than D10. This is the size at 10% finer by weight. Similarly, D60 is the particle size at which 60% of the particles are finer and 40% of the particles are coarser than D60 size.
What is the aperture size of sieve number 10?

What are the disadvantages of sieving?
The sieves may suffer damage, they are difficult to clean and dry, it is difficult to filter suspensions through sieves of smaller mesh, fat globules may plug the mesh, and processing the results requires much time and labour.
