Products:Particle Sizing The classic process of sieving as a particle size analysis method has been significantly improved during the last few years through technical advancements. Today, FRITSCH sieve shakers are small, high tech instruments. With program selection, evaluation software, power network adaptation and, in some cases, automatic amplitude control, they offer maximum precision and ease of use.
VIBRATORY SIEVE SHAKER, ANALYSETTE 3, PRO
Typical fields of application: The vibratory Sieve Shakers analysette 3 PRO and SPARTAN are the ideal instruments for determining quantitative particle size analysis by the well-known tried and trusted method of sieving. Particle size distribution of all kinds solids samples and suspensions can be measured by dry and wet sieving. The sieving process can be carried out with woven analytical sieves or micro precision sieves. The modular system of the analysette 3 allows for easy conversion to vibratory micro mill pulverisette 0 for milling and homogenizing small amounts of sample material. Method of operation: The analysette 3 is a "shaking sieve" system in the classic sense, with an electromagnetic drive in the base which vibrates the sieves vertically. The material to be sieved is propelled upwards periodically from the woven sieve cloth, as it returns to the mesh of the sieve it is forced through the apertures to the collecting pan located on the base. The regulated vertical action produces optimum material sizes for sieving and ensures an even distribution of the material over the entire sieve mesh. As there are no centrifugal effects, all forces act directly in the separating process of the sieves, almost regardless of the level acceleration. Features of performance:
The Vibratory Sieve Shaker analysette 3 is delivered without clamping lid, test sieves and sieve pan (which are available in different types and must be ordered as accessories), inc. control and evaluation programme AUTOSIEVE for WINDOWS™ standard version for test purposes limited for 180 days. The sieve tensioning system Torque Master which enables an automatic, reproducible tensioning of the sieve stack on the sieve shaker is also as an accessory available.

HEAVY DUTY SIEVE SHAKER, ANALYSETTE 18
Typical fields of application: The analysette 18 is primarily used for particle size analysis and grading of coarse-grained materials. The maximum feed quantity of 25 kg for sieving material and sieve stack means it can also be used in pilot plant production or in test series for larger quantities. Method of operation: The "analysette 18" is a vibratory sieving machine that has been specially designed for processing large quantities of material which requires sieving. It essentially avoids the disadvantages of lighter sieving machines in which the sample and sieve weights can sometimes bias the sieve results. Two unbalanced motors installed in phase opposition under exactly defined angles create optimum vibration of the test sieves mounted on the sieve plate. Both motors are precision braked at the end of the sieving time. This design means that the sieved materials are accelerated vertically as well as horizontally, causing the material to change direction continuously, thus producing shorter sieving times and sharper separation results. Features of performance:
The Heavy Duty Sieve Shaker analysette 18 is delivered without test sieves and sieve pan, incusive ttensioningand sieve cover, inc. control and evaluation programme AUTOSIEVE for WINDOWS™ standard version for test purposes for 180 days. The extended version must be ordered separately. When sieving fine-grained materials, the use of vulkollan cubes can be beneficial.
