TWO STAGES. ONE MACHINE.
✓ Single-shaft shredding (upper chamber)
✓ Gravity transfer between stages
✓ High-speed crushing (lower chamber)
✓ No conveying equipment needed
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.
Applications
Screen & knife configurable per material
Botellas PET
Whole PET bottles, preforms, and containers. Single-shaft stage handles bulky bottles, crusher reduces to flakes for washing line feeding.
Plastic housings
TV housings, appliance cases, computer shells. Single-shaft tearing handles large rigid pieces, crusher finishes to uniform regrind.
Composite cables
Cable waste with plastic insulation and metal cores. Single-shaft stage tears sheathing, crusher reduces to granules for separation.
Waste paper & films
Paper bales, film rolls, packaging films. Screen tuned for thin materials to avoid wrapping and achieve consistent particle size.
Tubos y perfiles
PVC, HDPE, PP pipe cutoffs and long profiles. Wide feed opening accepts long sections. No pre-sawing needed for most diameters.

Preguntas frecuentes
How does the single-shaft + crusher combination work?
The upper chamber contains a single-shaft shredder that tears large, bulky material into 50–100 mm pieces. These pieces drop by gravity into the lower chamber where a high-speed crusher with bolt-on knives reduces them to 8–15 mm uniform regrind. No conveyor between stages — gravity handles the transfer.
Can one SC Series handle different materials?
Yes — PET bottles, PP, PE, ABS, PS, HDPE all process well with standard D2 knives. Nylon and engineering plastics need DC53 or carbide knives for acceptable blade life. Clean the chamber between material changes to avoid cross-contamination. Screen swaps take about 30 minutes.
What maintenance does the SC Series need?
Two wear points: single-shaft shredder knives (600–1,000 hours on standard materials) and crusher knives (400–800 hours). Both use bolt-on designs — no welding on site. Routine checks: hydraulic oil level, screen condition, belt tension. One maintenance schedule for the entire machine.
SC Series vs buying separate shredder and crusher?
Choose the SC Series when you want one machine, one operator, one maintenance schedule, and ~50% less floor space. The integrated design eliminates the conveyor and the material transfer point. Choose separate machines only when you need very different throughputs per stage or material buffering between stages.
Do you ship and support overseas?
Yes, we ship globally. The SC Series ships pre-assembled — installation is positioning, leveling, and connecting power. We provide remote commissioning and can arrange on-site support depending on location and schedule.

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.

Preguntas frecuentes
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.
