What is a Corrugated Sidewall Belt Conveyor?

A corrugated sidewall belt conveyor, also referred to as steep angle cleated conveyor, is a professional bulk material transport device fitted with wave-shaped corrugated sidewalls and TC partition cleats on the base belt. It can convey bulk materials continuously at an inclination of 0° to 90° without material sliding or spillage. It can be arranged horizontally, in Z-type or S-type layouts without transfer points, which greatly saves floor space and construction costs. Widely used in cement plants, mines, quarries and port terminals, this heavy-duty conveyor is ideal for lifting cement clinker, ore, coal, aggregate and other bulk materials, and we can provide heat-resistant, flame-retardant and wear-resistant belts to adapt to various harsh working conditions.

Key Advantages of Corrugated Sidewall Belt Conveyor
Technical Parameters
Application Scenarios
Cases

Equipped with Sidewalls and Cleats
Flexible corrugated sidewalls form material pockets. Matched with cleats, they prevent bulk material spillage on steep slopes.
Variable Incline Conveying
The conveyor supports adjustable inclination angles and adapts to different industrial production lines.
High Incline Conveying Capacity
It works stably above 30°, which ordinary troughed belt conveyors cannot achieve.
Vertical Conveying Function
It lifts bulk materials vertically into silos and bins, simplifying the whole conveying system.
Compact Steel Structure
The steep-angle layout greatly reduces the equipment footprint and saves construction cost.
Dust Controlling Device Available
These conveyors handle various bulk materials, including coal, ore, aggregates, cement clinker and grains for mining, cement industry and port logistics. Sealed enclosures and dust suppression systems can be added as required.

Cement Plant

Our corrugated sidewall belt conveyor transports limestone, gypsum, raw meal and high-temperature clinker in cement production lines. Heat-resistant belts support steep-angle delivery of hot clinker, reduce silo height and lower construction expenses. Most large and medium cement plants replace multiple troughed conveyors with this large inclination model.

Mining & Quarry

It carries raw ore, crushed stone, coal and sand for metal mines, coal mines and aggregate crushing lines. Flame-retardant belts meet underground safety standards, and heavy steel-cord belts realize long-distance high-volume ore transportation. It is essential equipment for crushing and screening plants.

Port & Bulk Terminal

Ports adopt this vertical conveyor to load and unload coal, mineral sand and grain. Its compact design saves valuable harbor land. The fully enclosed cover meets environmental standards and stops dust pollution during bulk cargo transfer.

Other Industries

Thermal power plant: coal and boiler ash transportation
Aggregate yard: vertical lifting of finished sand and stone
Chemical plant: bulk powder material conveying
Construction waste recycling: lifting broken slag

Key Advantages of Corrugated Sidewall Belt Conveyor

Structure Composition of Large Inclination Conveyor

The whole steep angle conveyor consists of four main parts, all adjustable according to on-site conditions.

Base Belt

We provide EP polyester belts, NN nylon belts and steel-cord belts. Special belts with high temperature resistance, flame resistance and wear resistance are optional for clinker and underground mining.

Corrugated Sidewall

Wavy rubber sidewalls with height from 60 mm to 300 mm. They are vulcanized firmly onto the base belt so they will not peel off under long-term heavy load.

Cross Cleats

Ttype, C type and combined TC cleats can be selected. They block bulk materials from sliding down steep slopes and serve as the core anti-spillage structure.

Auxiliary Systems

Including drive unit, tension device, idlers, frame, safety components and full dust enclosure. We can also install weighing systems and reversible running devices on request.

Related Products

What is corrugated sidewall belt conveyor used for?

It is designed for steep and vertical transport of clinker, ore, coal, aggregate and grain. It solves the spillage problem of common troughed conveyors on steep slopes and saves plant space.

What is the maximum conveying angle?

It can work vertically from 0° up to 90°. TC cleats and corrugated sidewalls are required when the angle is more than 30 degrees to prevent material backsliding.

What is the difference between troughed belt conveyor and corrugated sidewall conveyor?

Troughed conveyors only work below 20°. Materials slide down on steeper slopes. Corrugated sidewall machines can lift bulk goods at 0–90° without spillage, though the cost is higher for low-angle horizontal transport.

Can this conveyor handle hot cement clinker?

Yes. We supply high-temperature resistant belts working steadily under 200℃, perfectly suitable for hot clinker conveying in cement factories.

What is the capacity of heavy duty mobile conveyor?

The conveying capacity of heavy-duty mobile conveyor can be customized from 10t/h to 300t/h. We can configure high-capacity industrial belt conveyor systems according to user’s bulk material handling needs.
