Kombinierte Schredder- und Brechanlage – SC Series

Upper shredding. Lower crushing. No conveyor.

The SC Series integrates a single-shaft shredder in the upper space and a high-speed crusher in the lower space. Material is shredded in the upper chamber and drops by gravity directly into the crushing chamber below. No transfer conveyor. No second operator. No double handling. The overall structure is compact with a small footprint and outstanding overall economy.

About the SC Series Shredder-Crusher Combined

The SLECOTECH SC Series Shredder-Crusher Combined is an integrated single-shaft shredder and high-speed crusher in one compact machine. The upper space of the equipment is set up with a shredding area, and the lower space is set up with a crushing area. Material enters the top hopper and passes through the single-shaft low-speed, high-torque shredding stage where the rotary shaft tears large, bulky feedstock into 50–100 mm pieces. The pre-shredded material drops by gravity directly into the high-speed granulator below, where bolt-on rotary knives reduce it to a uniform 8–15 mm regrind against a replaceable screen. There is no need for conveying equipment between stages. The overall structure is compact, with a small footprint and outstanding overall economy.

Wichtigste Anwendungsbereiche

• PET bottles and preforms — whole bottles to flakes for washing line feeding
• Plastic housings — TV cases, appliance shells, computer enclosures
• Composite material cables — cable waste with plastic sheathing and metal cores
• Waste paper and films — paper bales, packaging films, roll scrap
• Pipes and profiles — PVC, HDPE, PP pipe cutoffs and long profiles
• Nylon and engineering plastics — ABS, PC, PA with appropriate knife grade

Technische Vorteile

• Vertically integrated design: single-shaft shredder upper + high-speed crusher lower in one machine — no conveying equipment needed
• Gravity transfer between stages: no mechanical conveyor, no bridging, no energy consumption, zero maintenance at the transfer point
• Compact footprint: ~50% less floor space vs separate shredder + crusher + conveyor installation
• Single-shaft primary stage: low-speed, high-torque tearing handles bulky, irregular feedstock without jamming
• PLC control with independent motor overload protection and auto-reverse on jam for each stage
• Quick-change bolt-on knives on both shredder and crusher rotors — knife changeover without welding
• Adjustable crusher screen from 6–20 mm — swap in 30 minutes to match downstream process requirements
• CE-compliant safety: emergency stops at feed and discharge, interlocked access panels, safety guards

Häufig gestellte Fragen

Can the output feed directly to an extruder?

With an 8–10 mm crusher screen, yes — the regrind uniformity is sufficient for direct extrusion feeding. For applications requiring finer output (4–6 mm), a secondary granulator can be added downstream. Most in-house recycling operations use 8–15 mm regrind directly without additional processing.

What is the typical payback period vs buying separate machines?

Most customers see full payback in 8–14 months. Savings come from: one machine purchase instead of two, no conveyor to buy or maintain, one operator instead of two, one set of spares to inventory, and ~50% less floor space. For a mid-size recycler running the SC800, this typically represents EUR 15,000–25,000 saved in the first year.

SC Series vs separate shredder + crusher — which should I choose?

Choose the SC Series when you process mixed plastic scrap requiring both coarse tearing and fine crushing and want to minimize floor space, operators, and total cost of ownership. The integrated design eliminates the conveyor and transfer point. Choose separate machines only when your shredding and crushing throughputs differ significantly or when the process requires material buffering between stages.

What knife life should I expect?

Single-shaft shredder knives: 600–1,000 hours for standard materials (PP, PE, ABS, PS, PET). Crusher knives: 400–800 hours. Harder or filled materials (PC, nylon, glass-filled) reduce life by 30–50%. DC53 or carbide knives significantly extend life for abrasive applications. Both shredder and crusher knives are bolt-on — a full rotor change takes 2–3 hours for the shredder and 1–2 hours for the crusher.
