Chemical Plastic Pellet Bulk Tank Semi-Trailer
The Chemical Plastic Pellet Bulk Tank Semi-Trailer is a specialized, high-capacity dry bulk transport trailer engineered specifically for the clean, zero-contamination road haulage and automated pneumatic discharge of low-density free-flowing plastic granules and chemical raw materials (such as PE, PP, PVC, ABS, PET, and masterbatch pellets). Because plastic pellets are sensitive to frictional heat (which causes melting, stringing, or "angel hair" formation) and static electricity, the tank interior is precision-machined, mirror-polished, or lined with ultra-smooth epoxy, free of sharp weld burrs or crevices. Fabricated from lightweight marine-grade aluminum alloy (AL5083) or high-strength carbon steel, it utilizes a high-volume, low-pressure pneumatic delivery system powered by an oil-free blower or screw compressor that maintains low air temperatures to protect polymer integrity. Designed with a large volumetric capacity (45 $m^3$ to 75 $m^3$) to accommodate lower bulk densities, it features comprehensive anti-static grounding protection and quick-connect sanitary couplings. Paired with 3 commercial axles, air ride suspension, and dual-line WABCO ABS/EBS pneumatic braking, it delivers exceptional highway stability, purity preservation, and high-efficiency unloading. Fully certified under ISO9001, CCC, CE, DOT, and SGS standards.

Key Structural & Performance Features
1. Anti-Friction Smooth Interior & "Angel Hair" Prevention
- Seamless Internal Weld Grounding: All internal structural welds are ground flush and polished smooth to eliminate micro-burrs and sharp ridges, preventing plastic pellets from snagging, melting, or generating frictional "angel hair" strings during pneumatic transfer.
- Low-Density Volumetric Optimization: Engineered with a large volumetric capacity (up to 75 $m^3$) to match the lower bulk density of plastic granules (0.5–0.6 $t/m^3$), maximizing payload space without exceeding legal height limits.
- Anti-Static Electrostatic Safety: Equipped with comprehensive anti-static grounding measures, including continuous bonding copper strips, static dissipation wire meshes, and dedicated grounding reels to eliminate explosion and spark risks caused by polymer friction.
2. Low-Pressure, High-Volume Pneumatic Discharge System
- Friction-Reducing Low-Pressure Air: Powered by a specialized oil-free low-pressure blower that operates at 0.1–0.15 MPa, delivering high airflow volume while keeping air temperature low to prevent thermal softening or agglomeration of sensitive plastic pellets.
- Smooth-Radius Elbow Piping: All discharge manifolds and pipe bends utilize large-radius smooth curves and abrasion-resistant aluminum/stainless tubing, ensuring high-speed pellet flow without casing fracture or particle degradation.
- Near-Zero Residual Scavenging: Optimized steep hopper cone angles and centralized scavenging lines achieve a residual rate of less than $0.05\%$, ensuring absolute color and resin purity when switching between different chemical batches.
3. Integrated Chassis Stability & Running Gear
- Robust Sub-Frame Backbone: The lightweight tank structure is securely mounted onto a heavy-duty Q345B/Q550 structural steel sub-frame, evenly distributing dynamic payload weight across the multi-axle bogie.
- WABCO ABS/EBS Pneumatic Braking: Dual-line air braking system incorporating WABCO ABS/EBS and emergency relay valves, ensuring dependable, synchronized stopping power under full volumetric loads.
- Air Ride Suspension Smoothness: Pneumatic air suspension cushions sensitive polymer granules and tank structures from high-frequency highway shocks and road vibrations.
Commercial & Logistics Terms
- Warranty Policy: 3 to 5-Year warranty for the main tank shell structure; 1-Year warranty for axles, air blower, diesel engine, and discharge valves.
- Delivery Lead Time: 35 – 40 working days upon order confirmation and engineering drawing approval.
- Packaging & Shipping: Nude packing; shipped via Bulk Cargo vessel or Ro-Ro vessel.
- Payment Terms: T/T (Telegraphic Transfer), L/C (Letter of Credit).
