Anti-Slip & Heat Resistant Belt Conveyor for Special Industries

In the production and logistics processes of special industries, operating conditions often combine multiple stringent requirements such as high temperature, high humidity, high corrosion, large inclination, heavy load, and continuous operation. These place far higher demands on conveying equipment than in conventional scenarios. The widespread issue of inadequate equipment adaptability in the industry directly restricts production efficiency and operational safety.

I. Requirements for Belt Conveyors in Special Industries

Rigid Demand for Conveying Materials at Large Inclinations and Prone to Slippage

Conventional belt conveyors are only suitable for conveying scenarios with an inclination ≤12°. When faced with large-inclination (15°–45°) conveying demands such as slope lifting in mines, climbing conveying in grain storage, inclined loading and unloading at ports and terminals, and charging to smelting furnaces, or materials with low friction coefficients, easy rolling, and easy slippage such as coal, fine powder, wet sand, and granular materials, ordinary flat belts lack sufficient friction and are highly prone to material sliding, rolling back, and spillage. This not only causes material loss and pollutes the working environment but also drastically reduces conveying efficiency, even leading to failures such as material accumulation blocking equipment and damage to the conveyor belt. As a result, enterprises are forced to reduce the conveying inclination, increase equipment length and floor space, and significantly raise infrastructure and operating costs.

Meanwhile, in outdoor working conditions with heavy rain and high humidity, or scenarios where materials themselves have high moisture content (such as washed coal, wet ore, and fresh agricultural products), the friction between the belt surface and materials is further reduced, making slippage even more prominent. Conventional equipment can barely operate stably and continuously, becoming a core bottleneck restricting efficient conveying in special scenarios.

Equipment Service Life and Safety Assurance Under High-Temperature Conditions

In core production links of metallurgy, building materials, chemical, power, and other industries, material temperatures often reach 100℃–300℃, and in some smelting and roasting scenarios, temperatures can approach 400℃. Under continuous high-temperature environments, conventional rubber conveyor belts rapidly suffer from softening, deformation, cracking, aging, and delamination. This not only shortens their service life to 1/3–1/2 of that in normal working conditions but also triggers serious safety accidents such as conveyor belt deviation, tearing, and breakage.

In addition, high-temperature environments affect the performance of core conveyor components: drum rubber lining is prone to melting and falling off, idler bearing grease fails, thermal expansion and contraction of metal structural parts cause frame deformation, and electrical components age rapidly with frequent failures. This leads to a sharp increase in equipment maintenance frequency, extended downtime, direct disruption to enterprises’ continuous production plans, and higher maintenance costs and safety risks.

Comprehensive Adaptation Requirements for Special Industries

In addition to the two core properties of anti-slip and heat resistance, belt conveyors for special industries have multiple comprehensive requirements:

1. Reliability and stability: Capable of 24-hour continuous heavy-duty operation with an extremely low failure rate, adapting to unmanned operation and remote monitoring demands;
2. Weather resistance and corrosion resistance: Adaptable to complex outdoor environments such as sun and rain exposure, dust pollution, and acid-base corrosion, preventing component rust and damage;
3. Safety: Equipped with safety functions including deviation prevention, tear prevention, slip prevention, overload protection, emergency braking, flame retardancy, and anti-static properties, complying with international safety standards;
4. Versatility and customization: Not only adaptable to standard working conditions but also customizable according to material characteristics, conveying parameters, and site conditions in different industries to achieve multi-purpose and precise adaptation;
5. Environmental friendliness: Low noise, low dust, and no leakage, meeting increasingly stringent global environmental regulations.

II. Core Technologies and Structural Design of ZOOMRY Anti-Slip & Heat Resistant Belt Conveyor

ZOOMRY anti-slip & heat resistant belt conveyor is designed and developed in accordance with ISO international standards, EU standards, as well as Chinese GB/T 10595-2017 and GB50431-2020 codes. Integrating years of industry practical experience, it achieves technological innovations across five core modules: conveyor belt, drive system, idlers and pulleys, frame structure, and control system. It comprehensively solves anti-slip and heat resistance challenges under special working conditions, while balancing equipment stability, safety, and service life.

Anti-Slip Conveyor Belt

1. Surface anti-slip pattern design: Abandoning the conventional flat belt structure, a variety of patented anti-slip patterns such as herringbone (V-shape), diamond, corrugated, and ribbed designs are adopted, with the herringbone pattern being the mainstream choice in the industry. The opening direction of the pattern is consistent with the material running direction, which not only forms mechanical engagement between the raised pattern and materials to greatly increase the static friction coefficient (≥0.6, compared to only 0.3–0.4 for conventional flat belts) but also ensures smooth material discharge without residual accumulation. It enables stable conveying at large inclinations of 15°–45°, increasing the conveying angle by 2–3 times compared to conventional equipment. For ultra-fine powder and wet sticky materials, deep-pattern and high-damping pattern structures can be customized to further enhance grip and completely eliminate material slippage.

2. High heat-resistant anti-slip material: The conveyor belt cover rubber adopts special heat-resistant materials such as EPDM rubber, nitrile rubber, and fluororubber, paired with steel cord or high-strength polyester canvas carcass layers to form a three-layer composite structure:

• Bottom carcass layer: Steel cord (tensile strength 1000–6000N/mm) or polyester canvas core, high strength, low elongation (≤4% under rated load), meeting tensile requirements for long-distance and high-capacity conveying and avoiding tensile deformation at high temperatures;
• Intermediate buffer layer: Elastic rubber material that absorbs material impact, protects the carcass layer, and improves the conveyor belt’s tear resistance and fatigue resistance;
• Surface anti-slip & heat-resistant layer: High-friction, high-wear-resistance, and high-temperature-resistant formula, capable of withstanding long-term temperatures of 120℃–200℃ and short-term temperatures of 250℃–300℃. It maintains a stable friction coefficient in high-temperature environments without softening, material adhesion, or aging cracking.

3. Special process treatment: Adopting high-temperature vulcanization integrated molding to ensure firm bonding between patterns and the belt body without delamination or cracking; thickened belt edges to enhance tear and wear resistance; surface anti-slip, anti-adhesion, and anti-static treatment, adapting to special scenarios such as flammable, explosive, and high-dust environments.

Heat-Resistant Drive and Tensioning System

1. Heat-resistant drive pulley: The drive pulley adopts a thickened cast steel/steel plate welded structure, with surface treatment of diamond rubber patterns, herringbone rubber patterns, or ceramic rubber lining. The rubber lining material is high-temperature-resistant rubber (withstanding 150℃–200℃) or ceramic particles, increasing the friction coefficient by more than 50% compared to ordinary smooth pulleys. This not only enhances friction with the conveyor belt to prevent drive slippage but also maintains rubber lining strength at high temperatures without melting, falling off, or cracking. The pulley is internally designed for heat dissipation, paired with imported high-temperature-resistant bearings (SKF/NSK) and high-temperature grease, ensuring smooth bearing operation without jamming or abnormal temperature rise in environments ranging from -30℃ to 250℃.

2. High-efficiency heat-resistant drive unit: The drive motor adopts a variable-frequency explosion-proof motor or high-temperature-resistant motor with protection class IP55/IP65 and insulation class F/H, capable of continuous operation at ambient temperatures ≤80℃. The reducer adopts a hard-tooth surface planetary reducer or gear reducer with a thickened heat-dissipating box, filled with high-temperature-resistant gear oil internally, achieving transmission efficiency ≥95%, low noise, low vibration, and long service life. Paired with a hydraulic coupling or variable-frequency soft starter, it realizes smooth starting and speed regulation, reduces conveyor belt impact, avoids slippage during startup, and adapts to working conditions with large load fluctuations.

3. Intelligent tensioning system: Adopting hydraulic automatic tensioning, gravity tensioning, or screw tensioning systems, which automatically adjust tension according to the conveyor belt’s operating status to ensure optimal friction between the conveyor belt and drive pulley, eliminating slippage caused by insufficient tension. All tensioning components are made of heat-resistant and anti-corrosive materials, free from deformation and rust in high-temperature environments, with stable and reliable tension that requires no frequent manual adjustment.

High-Temperature-Resistant Idlers and Pulley Sets

1. Heat-resistant idlers: The idler shell is made of seamless steel pipe, ceramic composite pipe, or high-molecular heat-resistant material, with a smooth, wear-resistant, and non-stick surface. The bearing seat is made of cast steel with an internal double-seal structure (labyrinth seal + fluororubber sealing ring), effectively blocking dust, high-temperature gas, and moisture ingress. Bearings are imported high-temperature-resistant deep groove ball bearings filled with high-temperature grease, featuring low running resistance (friction coefficient ≤0.02), flexible rotation, and no jamming, capable of continuous operation at 150℃ for over 5000 hours without failure. The idler spacing is optimized according to conveying inclination and material weight, with dense arrangement at large-inclination sections to ensure uniform support of the conveyor belt without sagging or deviation.

2. Bend pulleys and impact pulleys: Bend pulleys share the same structural design as drive pulleys, with smooth or patterned surface treatment to meet different guiding needs. Impact pulleys/impact idler sets are installed at feeding points, adopting an elastic rubber buffer structure to absorb impacts from large and high-temperature materials, protect the conveyor belt and idlers, and prevent tearing or deformation caused by excessive local stress on the conveyor belt.

High-Strength Heat-Resistant Frame and Protective Structure

The frame is welded from Q235B/Q355B high-strength carbon steel, with the overall structure optimized via finite element analysis, featuring high rigidity and stability to withstand heavy loads, high temperatures, vibrations, and other complex working conditions. The frame surface undergoes three-layer treatment: sandblasting and rust removal + high-temperature-resistant anti-corrosive primer + high-temperature-resistant topcoat, withstanding 150℃–200℃, resisting rust, corrosion, and aging, and remaining rust-free for 10 years in outdoor use.

For special scenarios such as high temperature, dust, and high humidity, fully enclosed dust covers, heat insulation shields, rain sheds, and other structures are optional to reduce the impact of high-temperature radiation, dust pollution, and rain erosion on equipment. Material anti-fall baffles and protective nets are installed at large-inclination conveying sections to prevent accidental material slippage and ensure operational safety. Adjustable legs are installed at the bottom of the frame to adapt to different site flatness, enabling convenient installation and flexible adjustment.

Intelligent Control System

Equipped with a PLC programmable control system and touch-screen operation interface, it realizes automatic control, status monitoring, fault alarm, and remote management of the conveyor. The system has the following core functions:

1. Anti-slip monitoring: Real-time monitoring of the speed difference between the conveyor belt and drive pulley. Immediate alarm and automatic adjustment of tension or reduction of belt speed once slippage occurs to prevent worsening slippage;
2. Temperature monitoring: Temperature sensors installed at key parts such as the conveyor belt, drive motor, reducer, and bearings to monitor temperature changes in real time. Automatic alarm and shutdown in case of over-temperature to prevent high-temperature damage to equipment;
3. Safety protection: Integrated functions including deviation protection, longitudinal tear protection, overload protection, emergency stop, anti-reversal protection (for uphill large-inclination conveying), and soft braking protection (for downhill large-inclination conveying), complying with international safety standards;
4. Remote control: Supports network communication and can be connected to the enterprise DCS system to realize remote start-stop, speed regulation, monitoring, and fault diagnosis, adapting to intelligent and unmanned production demands;
5. Parameter adjustment: Flexible adjustment of belt speed, tension, conveying capacity, and other parameters according to material characteristics and conveying working conditions to achieve optimal operation and energy conservation (variable-frequency drive can save 10%–30% energy).
