Endecotts and the Advantages of Sieving

Perhaps the biggest advantage of test sieving is that it is a quick and reliable method of particle analysis, equally suited to accurate scientific research work or routine analysis under industrial conditions. Tests can be performed at almost any location.

No complicated apparatus is demanded. A nest of sieves and a simple laboratory balance will suffice in most cases. In fact, rapid size checks can often be made on-site at a particular plant with the aid of a rough pair of scales.

The technique of test sieving is simple. No specialised knowledge or skill is needed; care and diligence are the main requirements. Process operators can easily be trained to carry out sieve tests.

When the size distribution of a sample has been determined by test sieving, the material becomes separated into several fractions. This is another important attribute. These fractions are not contaminated, nor have their chemical or physical properties been altered. They are, therefore, available for further inspection or independent analysis if required.

The above testing procedure of sieving by hand can be tedious and the accuracy of the method may also depend on the operator who performs the test. With machine sieving most of the burden is removed from the operator, and once the optimum conditions have been determined, reproducible results are rapidly obtained.

For example, the nest of sieves may be shaken for a certain predetermined time e.g. 5 mins and amplitude e.g. 1.5 mm. This ensures that results from different labs can be compared with a large degree of accuracy.

Whether you are looking for test sieves or sieve shakers, Endecotts offer the world’s finest equipment.
