Industrial plastic barrel shredders specialize in processing high-density polyethylene (HDPE) and polypropylene (PP) containers up to 220L capacity. These engineered systems overcome unique challenges posed by thick walls (3-8mm), metal components, and residual chemicals to achieve >98% material purity at throughputs of 1-5 tons/hour.

This industrial shredder setup is absolutely nuts! Those torque numbers are wild 🤯
Anyone know if they’ve tested this on those blue chemical barrels? We’ve been having issues with residue in our facility.
98% purity with those thick walls is seriously impressive engineering
Lol imagine getting your hand caught in one of these bad boys 😅 OSHA would have a field day!
The ROI numbers seem optimistic – our plant barely hits 1.5 tons/hour with barrels full of sludge
