Product SpecificationsArchitectural Principles of Custom Portable Conveyors
Solving bulk material handling bottlenecks requires decoupling permanent structural installations from flexible logistical needs. Modern processing terminals demand high mechanical rigidity, rapid deployment capabilities, and modular wear protection.
"In heavy salt-chemical refining, bromine derivatives, and corrosive aggregate handling, stationary conveyor structures fail prematurely due to micro-vibrations, stagnant corrosive dust pockets, and inflexibility during processing configuration changes. The modern paradigm relies on modular mobile conveyor units engineered with corrosion-resistant metallurgy, anti-abrasive linings, and autonomous height adjustment."
Modular Structural Chassis
Engineered with stress-relieved tubular carbon steel and lattice truss designs, our portable conveyor frameworks withstand high torsional flex during raw material transit over uneven terrain, ensuring precise idler tracking and zero belt misalignment.
- Heavy-duty pneumatic radial wheels
- Hydraulic telescoping height adjustment
- Dual-point tow hitch for rapid yard relocations
Aggressive Corrosion Shielding
Direct exposure to wet salts, brine vapor, calcium chloride slurry, and acidic chemicals degrades conventional conveying machinery within months. We integrate carbon-steel pressure bodies, PTFE-lined conduits, PP coatings, and multi-ply food-grade/chemical-grade belt matrices.
- C5-M marine/chemical industrial coatings
- High-density UHMWPE skirt-board liners
- Anti-acid / oil-resistant belt compounding
Intelligent Power Transmission
Equipped with high-efficiency IP65/IP66 geared electric drive drums or shaft-mounted motor reducers. Integrated frequency control allows precision flow matching, soft starting under full payload, and instant torque protection against mechanical jamming.
- Variable frequency drive (VFD) flow modulation
- Thermal cut-off and zero-speed sensors
- Dual-direction emergency trip-cord lines

Localized Operational Assurance & Turnkey EPC Execution
Ruitu Automation bridges the gap between Chinese factory fabrication and global on-site commissioning. We guarantee smooth project startup through our structured Engineering, Procurement, Construction (EPC) approach.
1. Material Lab Analysis
Before metal is cut, our chemical process engineers run exhaustive laboratory grain-size, moisture, angle of repose, and chemical reactivity screenings on your bulk crude salts, minerals, or brines.
2. Modular Containerization
Our custom portable conveyor systems are engineered specifically for 40-foot HQ shipping containers. Pre-wired junctions, pinned modular truss segments, and bolt-together frames slash field erection times by 70%.
3. Expatriate Field Teams
Experienced site engineers travel to your terminal to supervise physical assembly, align motor gearboxes, calibrate automated weight-scales, and conduct intensive operator training until designed throughput is reached.
4. Rapid Spares Consignment
We maintain regional spare parts buffers for wear-intensive items (conveyor belt sections, idler rollers, bearings, screw flighting segments, and lined gaskets) backed by international priority air-freight agreements.

Frequently Asked Questions by Global EPC Contractors
Get direct engineering answers regarding custom design limitations, lead times, corrosion protection grades, and turnkey on-site integration.
How does Ruitu configure portable conveyors for highly corrosive salt and chemical environments?
We implement a multilayer defense system: hot-dip galvanized or high-build epoxy C5-M marine-grade coated structural frameworks, 304 or 316 stainless steel hardware, self-cleaning return idlers, and anti-static, chemical-resistant rubber/PVC belting. For fluid and slurry transfer, our carbon-steel components are fully lined with high-integrity PTFE or PP to eliminate metallic exposure.
What is the typical fabrication and delivery timeframe for custom conveyor machinery?
Standard custom mobile conveyor designs (15m to 30m lengths) generally require 3 to 5 weeks for manufacturing, structural testing, and corrosion finishing in our Weifang workshops. Complete turnkey salt washing or chemical conveying systems range from 6 to 10 weeks depending on custom automation, instrumentation, and valve package specifications.
Can your equipment accommodate overseas voltage, frequency, and motor compliance standards?
Yes. All motors, geared reducers, and VFD control panels are customized to match your destination grid (e.g., 380V 50Hz, 440V 60Hz, 460V/480V 60Hz). We source globally certified electric prime movers (including Siemens, ABB, or domestic explosion-proof certified equivalents) carrying CE, UL, CSA, or ATEX labels per project requirements.
What technical information is required to receive a formal engineering quotation?
To provide an accurate technical and commercial proposal, we request: (1) Bulk material profile (bulk density, lump size distribution, moisture, corrosiveness/abrasiveness); (2) Desired continuous throughput (metric tons per hour); (3) Conveying geometry (length, discharge height, fixed incline or radial stacker); and (4) Site utilities and ambient operating temperature ranges.
How does Ruitu assist with overseas installation, commissioning, and spare parts?
We dispatch certified mechanical and electrical commissioning engineers to lead field assembly, oversee wiring, and run full-load trial batches. We also provide comprehensive operations and maintenance training in English. Every system ships with a 2-year recommended consumable spare parts package.
What advantages do cold-rolled continuous auger blades have over segmented flights?
One-time formed cold-rolled screw flights feature smooth continuous surfaces without welded joint discontinuities, which eliminates material sticking points, dramatically improves dynamic balance at high RPMs, and provides uniform mechanical wear resistance throughout the conveying cycle.
