Stratoplex ASP II

Que el clasificador de aire Stratoplex ASP es garantía de alto rendimiento en el sector de la separación fina y media no es ninguna novedad. Sin embargo, hemos vuelto a mejorar este clásico en estrecha colaboración con nuestros clientes. El resultado: un concepto de máquina optimizado con menor desgaste y menor necesidad de energía.

  • Clasificador de aire estándar para un alto rendimiento en el rango de separación de finos a semifinos de d97 = 10 - 150 µm
  • Gran capacidad para finos con alta eficiencia de separación y alta carga de material
  • Protección contra el desgaste gracias al revestimiento cerámico en ambas caras
  • Demanda de energía reducida

Excellent flow behaviour

For higher fineness at the same speed

Small change, big effect: The following advantages result from an optimised design of the ASP II: To achieve the same fineness, the speed can be reduced by up to 20 % compared to the previous model. This means: Compared to the previous model, the Stratoplex ASP II has lower energy consumption and less wear. However, if the speed remains the same, the optimised separator wheel can separate more finely. By changing the classifier wheel, finenesses are now possible that could not previously be achieved.

Because the drive of the Stratoplex air classifier is fitted underneath the classifying zone and the feed product is fed centrally from above, the result is an optimum distribution and dispersion of the product. The feed product is charged by means of the feed unit via the product intake to the centrifugal plate of the classifying wheel, where it is distributed uniformly and then catapulted radially towards the baffle ring. The feed material is deflected by the baffle ring and routed downwards into the classifying zone.

The classifying air enters the spiral housing and flows through the helical vanes of the vane ring and the classifying wheel in centripetal direction. The fines portion is removed thereby from the feed material as it gravitates downwards in the classifying zone, i.e. the zone between the vane ring and the classifying wheel.

The fines, extracted as a function of the cut point set on the classifier, are entrained in the classifying air and flow towards the fines discharge. The fines must be separated from the classifying air in a downstream collection device (cyclone, filter). The coarse material is rejected by the classifying wheel and falls into the lower section of the classifier as the result of gravity.

The coarse material discharge must be air-sealed by means of a rotary valve. Rinsing air, either drawn in automatically or supplied under pressure, prevents unclassified product from migrating into the fines through the gap between the classifying wheel and the labyrinth seal. The classifying wheel is usually driven via a V-belt drive with a fixed transmission ratio; the classifier speed can be set by means of a frequency converter. The classifier is delivered complete with filter, fan and cyclone.

The classifier ASP II can be operated in the following modes:

  • Through-air mode
  • Circuit-air mode with approx. 10 % leakage air

The compact and modular design of the Stratoplex air classifier results not only in maximum performance at modest dimensions, but also permits an easy and space-saving system configuration. And because most of the main components can be accessed easily from above, Stratoplex air classifiers are quick and easy to maintain.

Applications

The air classifier Stratoplex ASP II is used above all for processing feldspar, quartz, nepheline, wollastonite, etc.
