Spinning impurities ragger SN

Spinning impurities ragger SN is designed for drawing of spinning impurities out of pulper chest particularly at waste paper pulping. The machine is recommended only for continuously working pulpers with chest diameter exceeding 3.800 mm. A necessity for tangle creation is a sufficient quantity of spinnable impurities, such as strands, rags, wires, synthetic foils etc.

Design

The ragger frame is anchored by four anchoring bolts. In the frame bottom part there is a driven shaft with its end provided with a spiked pulley. This pulley is driven by an electric motor with its gearbox.
The pressure pulley is pivoted in the frame top part and acts on a tangle by its own weight. Its swinging is controlled by a pneumatic cylinder attached to the frame. If necessary, it is possible to swing it manually by means of a lever put on the extended pin. Quantity of spinning impurities being drawn out depends on the stock impurity rate. The ragger operating speed can be regulated in dependence on quantity of impurities so that the tangle diameter is kept within a range from 100 to 200 mm. A necessity for tangle creation is sufficient quantity of spinning impurities in loaded materials. For example, cores and cardboards of bigger sizes bring negative impacts on creation and drawing of tangle as they entangle and the tangle cannot go through the output branch.

Material

Machine is made of structural steel St 52. Its exposed parts are made of special high-grade steels. External surfaces are protected against corrosion with high-quality polyurethane coating.

Machine design and work safety are in compliance with EU standards.
