Pure Performance: PACO MA-G 10 Screening Machine


A few weeks ago, following numerous years of planning and development work, PACO shipped the first MA-G 10 screening machine built at their own mechanical engineering facility. For the first time ever, a screening machine is now available that can separate even heavily agglomerated bulk material particles or materials that tend to get trapped.

This is enabled by high acceleration values in conjunction with a uniquely high filter oscillation and PACO metal wire cloths and screen frames that have been specially developed to withstand the extreme physical load that they are under. Patents are pending for the PACO MA-G 10 screening machine.


There are certain materials that regularly test the limits of existing screening technology. This is particularly the case when the particles to be separated have a strong tendency to stick to each other – due to humidity or heavy oil, for example. Conventional screening machines generally have to admit defeat, and even ultrasonic screening technology is often powerless in such situations: the generated amplitude of the screen, in the region of 0.1 – 0.2mm, is simply not enough.

In addition, the currently attainable acceleration rates also prove to be insufficient. Screening machines that are considered to be state-of-the-art attain a maximum screening acceleration of 6.39g. This is, however, too low for the separation of heavy oil and sand mixtures or heavily agglomerated fine particles.


The PACO MA-G 10 screening machine offers true high performance in every respect. With acceleration values of 10.5g and an amplitude of 4.4mm with a throw of 8.8mm, the PACO MA-G 10 is currently a in a class of its own. This gives the user advantages that, until now, were completely unobtainable.

High screen acceleration is particularly important for the fine screening of media with a tendency to agglomeration. As the material being screened has a very low mass, the screen oscillation (amplitude) has to throw it as high in the air as possible. In this way, the impact when it hits the screen will effectively break it up so that it can be conveyed through the screening machine. The larger the screen acceleration, the higher the specific extrusion capacity. Subsequently, the falling particles have to hit the screen at the exact moment that this reaches its maximum speed on the way back up.

The maximum relative impact speed between the particles and the screen will ensure an optimum separation, even of fine powders, heavy oil and sand mixtures or any other materials that tend to be strongly stuck together. This also applies to the de-watering of products with residual moisture.

The machine will go into series in the third quarter of 2007. In the MA-G 10, PACO bears witness to further proof of the innovative potential and global competitiveness of medium-sized enterprises in this country.
