Industrial shredders for light and heavy scrap
The Blue Devil twin-shaft shredder is the most performing and effective solution currently on the market to carry out the fragmentation of metal scrap. The bulk scrap is cut into small dimensions, increasing its density and freeing the precious and non-precious metals that are easily recovered with dedicated separation lines. The use of high resistant steel makes our machine the strongest in its category and allows the use of very high torques to cut particularly difficult materials and thicknesses, guaranteeing never seen before levels of performances in the total safety of the machine and its components.
The technology of the high engineering applied to the shafts is distinguished by its robustness excellent construction materials, precision machining operations, and consequently significantly improved work performance. All the drive assembly is positioned in a separate container, soundproof, lighted, and ventilated. When a critical working situation is detected, the PLC is able to activate in a few fractions of a second a series of preventive actions, such as slowing down the shafts or inverting their rotation direction.
The PLC manages automatically the speed change of the shafts according to the resistance force during shredding. The machine normally rotates at maximum speed (6 RPM) and, when the torque threshold set in the PLC is exceeded (a value that can be changed based on the work recipe selected by the operator), the speed is reduced to 50%, allowing the system to generate twice the torque.This setting can be modified according to the program set by the operator. If the shredder is not able to shred the input material it will carry out reversal rotation. From a sophisticated PLC to remote assistance in addition to keeping track of the variables and alarms and monitoring all the KPI indexes (Key Performance Indicators) necessary for an analysis of the operating statistics by both our technicians and the user, the sophisticated PLC of the blue devil includes technologies designed to offer advanced, simple and timely management.
The data is collected locally in the electrical panel memory and published on the Zato service portal to be backed up and to conduct predictive analyses useful for maintenance and troubleshooting. It is equipped with a 10” high definition touch screen to view all the useful information and simultaneously to interact with other functions to increase efficiency and flexibility of use and apply preventive measurements for the safety of the system. The 3 models, from Diesel to electric driven engines, are able to cover all the needs of the market reaching performances in terms of productivity which are as of today unmatched by machines offered by other manufacturers.
