ZZ300X300 HEAVY DUTY SCRAP SHREDDER REJECT DOOR, HIGH MANGANESE STEEL, UNIT WEIGHT 11500KG
This reject door is a heavy-duty spare part for shredder equipment, cast from premium high manganese steel with a single weight of 11,500 KG. Featuring outstanding work-hardening performance, the material gains higher surface hardness under continuous impact while retaining excellent internal toughness, which effectively resists severe abrasion and impact load during shredding operation.
Strict casting and heat treatment processes guarantee stable mechanical property, compact internal structure and precise dimensional accuracy for perfect fitment. Designed for rapid removal of unshreddable foreign objects, it protects the shredder rotor and main chamber from damage, minimizing downtime. Widely used in scrap metal recycling and heavy crushing lines. Reliable, long service life and low maintenance cost.
