Pre Crusher SPR
Pre-Crusher designed and manufactured by SPR Group. The evolution of the Bag Opener SPR.
Pre-Crusher SPR incorporates improvements and modifications in the design, with respect to the Bag Opener SPR model, in terms of wear resistance and robustness. The equipment has anti-wear reinforcements in all the elements of the crushing chamber. This fact means that it is a very valid equipment, both in the treatment of Waste Electrical and Electronic Equipment (WEEE), Municipa Solid Waste (MSW) and Municipal Organic Solid Waste (MOSW).
Pre Crusher SPR, thanks to its adjustable 5-way gate that allows automatically opens or closes the gap between the blades of the rotor and the counter-blades of the gate.
Its function, within the evaluation line, will be performing a first crushing of the material, allowing easy separation of its internal components without being aggressive with the recoverable fraction, and thus dosing it, for its future treatment and recovery.
The material falls on a rotor that incorporates blades without cutting edge, since its function is not to cut, but to crush the material due to the pressure exerted by these blades against the blades that are in the adjustable gate.
The low speed of the rotor causes the material to jump up through the part of greatest weakness (usually the joints), which allows to recover intact printed circuit boards or other components of interest.
