TL Low-Speed Crusher, Silent Low-Speed Plastic Shredder for In-Line Instant Recycling Next to Injection Molding Machines
Developed specifically for in-situ recycling in high-end precision injection molding factories, the Tenglong TL low-speed crusher is a dedicated low-speed in-line recycling model for TL series beside injection molding machines. It covers a full small power range of 1.1–4kW, equipped with an exclusive 20rpm ultra-low-speed pineapple blade cutting structure, featuring three core advantages: ultra-low noise, ultra-fine dust output, and closed-loop in-line recycling. Matched one-to-one with single injection molding machines, the equipment crushes sprues, runners, and defective plastic parts, then delivers materials directly to the machine hopper via wind power. It realizes zero waste storage and real-time closed-loop recycling production, serving as the standard silent low-speed plastic crusher for high-standard molding workshops such as precision electronics, transparent optics, and multi-color modified plastics.

- Four-Gradient Model Parameters, Precisely Matching Injection Molding Tonnage
The four models are designed hierarchically according to injection tonnage and runner size, featuring small footprint and universal casters for flexible displacement. Compatible with all horizontal and vertical injection molding machines. The full series adopts screenless structure and built-in wind feeding system. Complete parameters are as follows:
| Model | Power | Crushing Cavity Size | Net Weight | Blade Configuration | Matching Injection Tonnage | Applicable Materials |
| TL2530 | 1.1kW Mini Model | 250×300mm | 240kg | Simplified pineapple blade set | 80–160 ton small injection machines | Thin-wall small parts, fine runner exclusive materials |
| TL3030 | 1.5kW Standard Main Model | 300×300mm standard cavity | 310kg | 6 fixed pineapple blades | 160–280 ton mainstream injection machines | Conventional ABS, PP, PC general runner materials, factory bestseller |
| TL3040 | 2.2kW Enlarged Cavity Model | 305×415mm extended cavity | 420kg | 3 moving blades + 6 fixed blades | 280–450 ton medium injection machines | Thick large runners, medium & large defective parts, anti-jamming crushing |
| TL3050 | 4kW Heavy-Duty Large Model | 380×480mm super-large cavity | 580kg | Reinforced heavy-duty pineapple blade set | Above 450 ton large injection machines | Thick-wall large plastic parts, thick sprues, glass fiber modified hard materials |
- Core Low-Speed Pineapple Blade Configuration: Low Noise, Less Dust, Double Blade Service Life
2.1 20rpm Ultra-Low-Speed Silent Shearing
Different from mainstream high-speed impact crushers above 600rpm, the full range of TL low-speed crushers adopts constant 20rpm low-speed pineapple blade shearing operation, reducing overall operating noise by over 40%. No soundproof room or noise reduction accessories required, easily passing factory environmental noise annual inspection. Slow meshing shearing produces no high-speed impact heat, keeping plastic molecular structure intact with almost no performance attenuation. Transparent PC and acrylic materials resist yellowing and modification; tough PP materials avoid brittleness and fracture, fully meeting high-end plastic recycling standards.
2.2 Double-Sided Reversible SKD-11 Alloy Blades
Factory-equipped imported quenched high-hardness SKD-11 pineapple blades with double-sided cutting edges for reversible reuse. When one side is worn and dull, simply flip the blade to restore brand-new cutting performance, doubling the overall blade service life. The steel features high impact resistance, wear resistance and chipping resistance, suitable for long-term high-frequency in-line crushing of glass fiber reinforced plastics, hard ABS and modified filled materials without deformation or edge curling.
2.3 Screenless Adaptive Uniform Granule Structure
Eliminating traditional screen hole blocking and jamming defects, the fixed gap of pineapple blades precisely controls discharge particle size with uniform and regular granules. Fine dust proportion is lower than 5%, greatly reducing floating raw material loss and bridging blockage caused by fine dust accumulation. The recyclable material mixing ratio can be stably increased to 30%–50%, maximizing new plastic raw material cost savings.
- Siemens Intelligent Electric Control + Multiple Safety Protection, Automatic Anti-Jamming & Worry-Free Operation
3.1 Intelligent Reverse Automatic Blockage Removal System
The full set of electric control components of the low-speed crusher adopts first-tier Siemens electrical parts with strong anti-interference capability and ultra-high operational stability. When thick large runners or special-shaped plastic parts jam the blade group during production, the system identifies overload within milliseconds and automatically triggers motor reverse feeding to discharge blocked materials independently. No manual disassembly or prying is needed, without interrupting the injection molding cycle, ensuring continuous assembly line production.
3.2 Dual Industrial Safety Lock Protection System
First, built-in motor overload current protection automatically cuts off power under overload and jamming to prevent reducer motor burnout. Second, the hopper flip cover and cavity maintenance door are equipped with power interlock travel switches, forcing full power cutoff during cavity opening maintenance, completely avoiding accidental startup injuries during manual cleaning and blade replacement, fully complying with industrial injection workshop safety production specifications.
3.3 Integral Pull-Out Quick-Disassembly Blade Frame
When switching plastic colors or material grades, the integrated blade frame can be fully pulled out for dead-angle-free cavity wiping cleaning, fundamentally eliminating color residue and cross-color contamination. Ideal for multi-color precision matching and medical transparent part orders. Single-person operation completes material replacement and cleaning, greatly reducing cross-color scrap loss.

- Full Standard Instant-Crush & Instant-Feed Closed-Loop Recycling System
Each TL low-speed crusher is equipped with a silent high-pressure feeding fan and closed conveying duct. Equipped with universal casters, the machine is closely placed beside the injection molding machine. Dropped runners and defective parts automatically slide into the hopper for on-site instant crushing. Qualified particles are directly delivered to the injection molding machine drying hopper through closed ducts in real time and mixed with new materials for reproduction. Zero material stacking, zero long-term water absorption oxidation and zero performance degradation greatly reduce defective rates of shrinkage, color difference and brittleness. The movable design allows one machine to serve multiple injection machines for emergency crushing, improving equipment utilization.
- Core Applicable Production Scenarios
The low-speed crusher is suitable for precision electronic connector injection molding, transparent acrylic/PC optical lens molding, multi-color daily product injection molding, glass fiber reinforced modified plastic molding, and medical device clean plastic part production. It is the preferred one-to-one in-situ recycling equipment for high-end molding workshops with strict control over workshop noise, dust, recycling quality and cleanliness.
