Heavy duty pre-shredder(double shaft shredder) for light scrap steel and Aluminum scrap bale shredding
product scenario


Equipment Introduction
Description:
The pre-shredder is special focus on heavy metal scrap processing or AUTO body shredding, The high torque and Hard alloy cutter bring in high efficiency when it be used in pre-treatment of scrap metal. Our hydraulic pre shredder has been used in many ASR plant, like in Australia.

Features:
1. Reducer: adopts planetary reducer, coupling installation, with small size, compact structure, large output torque, smooth operation, etc., reducer mounting seat and box are processed as a whole to ensure easy installation;
2. Crushing box: the box is machined and boring as a whole by a high-precision CNC machining center to ensure that the equipment can run smoothly for a long time with high load, and extend the service life of the transmission components. The front and rear bearing seats are integrated to ensure the coaxial degree of the bearing holes at both ends. Open and close design, convenient for the complete spindle disassembly;
3. Multiple sealing inside bearing seat, waterproof and dustproof. The bearing seat is equipped with a wear-resistant baffle plate to prevent the material from contacting the bearing seat directly;
4. The blade adopts unique patent design, fully detachable tool design, easy to quickly replace and maintain the tool, reduce the production cost;
The machine is controlled by Siemens PLC through automatic detection, alarm and overload protection functions, which can automatically adjust and control the feed amount. When the motor pressure exceeds the set rated pressure, the automatic reversal is reversed, and then the automatic forward rotation enters the normal crushing action.
