ZOOMRY
The large-inclination conveyor overlaps with various crushing, screening, feeder, stacker and reclaimer and other equipment on the production line, and is used for transporting various bulk materials in the factory area. It can be flexibly arranged according to the needs of the production line, the length is based on site needs, and the inclination angle can be selected arbitrarily within -30° to +30°.
How a Large Inclination Belt Conveyor Works
A large inclination belt conveyor increases the friction between the material and the belt surface by applying additional pressure or increasing the contact surface area. This is typically achieved through the use of cleated belts, chevron patterns, or corrugated sidewall belts. These design features prevent material from sliding backward during steep-angle transport, allowing the system to operate efficiently at inclines up to 30°.
The conveyor can be flexibly arranged according to production line requirements, with length customized based on site conditions. It overlaps with various crushing, screening, feeding, stacking, and reclaiming equipment on the production line, serving as a key link in continuous material handling systems.
Key Design Features
Space-saving design
By conveying materials at steep angles, the large inclination belt conveyor significantly reduces the horizontal length required compared to traditional conveyors, making it ideal for confined plant layouts.
Cost efficiency
Mechanized conveying reduces project investment costs by approximately 20% to 40% compared to combined systems using horizontal conveyors and bucket elevators.
High standardization
Simple structure, easy maintenance, and reliable operation. Components are interchangeable with standard conveyor systems.
Versatile material handling
Suitable for a wide range of bulk materials including coal, ore, limestone, aggregates, and cement.
Flexible layout
Can be arranged in various configurations — straight, curved, or combined with other equipment — to match production line requirements. It can replace the combined unit of horizontal conveyor and bucket machine (two machines in one or three machines in one).
Long service life
High-strength belt construction and durable components ensure extended operational life with proper maintenance.

Belt Sway Switch
Detect whether the belt is deviating and send out a slight alarm or shutdown signal. Deviation will damage the belt and cause safety accidents. Deviation switches need to be purchased and installed in pairs.
Pull Cord Switch
Pull the wire rope to realize the switch action, which is used for emergency shutdown. It is a safety switch and is arranged along the entire length of the fuselage.
When an emergency occurs on the belt conveyor, the conveyor can be stopped urgently at any position. There are single-sided and double-sided arrangements. They are generally used in conjunction with walkways.
Zero Speed Switch
Detect whether the belt is slipping with the head roller. After slippage occurs, the Conveyor Belt speed will decrease. When the transport volume is overloaded, the belt tension is insufficient, or the rubber layer of the driving roller is worn out, slippage may easily occur. The conveyor belt speed can be monitored (also the rotational speed is calculated) or the drum rotation speed can be monitored.
If the belt conveyor in the stacker encounters an unexpected situation, such as a power outage or a broken wire rope, the stacker has a self-protection function:
- The winch motor has a self-locking function of 0.01 seconds when the power is cut off.
- The stacker has 2 mechanical mechanisms. If stuck, the internal unit will not slip to the bottom all at once. There are two designs in the middle to prevent jamming.

Frequently Asked Questions About Large Inclination Belt Conveyors
What is the maximum inclination angle for a large inclination belt conveyor?
For standard belt types with chevron or cleated patterns, the maximum operating angle is typically 30°. For special designs using corrugated sidewalls or pocket belts, angles up to 60° can be achieved. The actual angle depends on material characteristics such as particle size, moisture content, and flowability.
What types of belts are used for large inclination conveying?
Common options include: (1) chevron belts with raised V-shaped patterns, (2) cleated belts with vertical barriers, (3) corrugated sidewall belts with flexible edges and integrated cleats, and (4) pocket belts for extreme angles. The selection depends on the angle, material properties, and capacity requirements.
How does a large inclination conveyor prevent material from sliding back?
The belt surface features specialized patterns (chevron, cleats, or sidewalls) that increase friction and create physical barriers. Additionally, the belt tension and idler spacing are optimized to maintain proper contact pressure between the material and the belt, preventing backward sliding during steep-angle transport.
What is the typical capacity range for a large inclination belt conveyor?
Capacities range from 100 m³/h to 15,000 m³/h, depending on belt width, speed, and material density. For example, a 1,400 mm belt operating at 2.5 m/s can handle approximately 2,000–3,000 t/h of crushed ore or limestone.
Can a large inclination conveyor be combined with curves?
Yes. As shown in project references, large inclination conveyors can incorporate horizontal curves to follow terrain and avoid obstacles while maintaining steep inclines. Multiple curved sections can be combined in a single conveyor flight.
