The mobile classifying groups satisfy all the characteristics of Alquezar products: Reliability, versatility and economy of use. Equipped with running gear or with skids (semi-mobile versions) they can quickly and easily be transferred from one work area to another.

The classifying system is comprised of feed hopper, pre-screening grid, belt feeder, sloping feed belt, vibrating screen and stockpiling belts (depending on the model).

The belts are positioned and adjusted hydraulically, thanks to the incorporation of a hydraulic pump assembly.

Frequency variators can be incorporated as optional elements, which permit the adjustment of the supply and vibration speed of the equipment.
