Sieve Systems

An array of ultrasonic and standard sieve systems for “cutting” powders according to the sieve sizes shown:

We use a variety of different sieve procedures at MPP to isolate different particle size fractions.  This includes:  Hand sieves, Ultrasonic sieves, multi-frequency technology and centrifugal classification.

Ultrasonic Sieve Deblinding

Ultrasonic sieves to prevent blinding and blocking of mesh and maintain consistent flow rates

Russell Finex’s innovative ultrasonic sieve deblinding system has revolutionised the way difficult powders are screened on sieve meshes, increasing capacities and allowing accurate separation down to 20µm. Known as the patented Vibrasonic^® Deblinding System (VDS), the system consists of a generator and a probe and applies an ultrasonic frequency directly to the mesh screen, effectively making the mesh wires friction free and eliminating blinding and blocking of the mesh apertures.

MPP also uses a revolutionary vibrating sieve shaker technology. It consistently outperforms other mesh screen brands in its ability to significantly increase capacity and efficiency (over 99{d3983698f6bbfcfc9ce20a58bcd34d9e7e79e593f810ce5bf49abd797b6c13c4} purity of particle size) for problematic materials that are wet, sticky, abrasive or fine.

The vibrating sieves utilise patented protected multi-frequency technology that converts single-frequency oscillations into multi-frequency movement. As a result, the acceleration that is transmitted to the mesh screen reaches 500G as opposed to the 5G delivered by traditional screeners. The advantages that this equipment provides over traditional single-frequency machines includes:

• significant increase of screening capacity and efficiency (up to 99{d3983698f6bbfcfc9ce20a58bcd34d9e7e79e593f810ce5bf49abd797b6c13c4} particle size purity) for previously impossible or difficult to screen materials (eg; sticky, wet, fine or abrasive materials);
• significant reduction/eradication of waste;
• reduction of energy consumption;
• creation of new revenue streams;
• increase of screen mesh screen lifetime, and more.
