Conveyor Roller
Our single conveyor roller is independent cost-saving replacement spare parts specially designed for cement and mining belt conveyors; different from complete bracket-equipped idler assemblies, only worn rollers need to be replaced to greatly cut your maintenance budget, it adopts dustproof anti-impact thick tube and multi-layer labyrinth sealing to block cement dust and ore impact, and flexible customized sizes are available.
Custom Conveyor Roller & Complete Conveying System Solutions
Darko provides full custom design and manufacturing services for single conveyor rollers and whole bulk material conveyor systems. No matter you need special diameter, wall thickness, surface material or sealing structure to match your old equipment, our technical team can design and produce rollers fully according to your site working conditions, material features and layout demands. We also support one-stop customization for matching conveyor frames, belts and auxiliary spare parts to form a complete stable conveying line for cement plants, mines and aggregate yards.

Steel Conveyor Rollers
Our heavy-duty steel conveyor rollers are standard spare parts for cement and mine belt conveyors. Made of thick seamless steel tube with multi-layer dust-proof sealing, they can bear heavy ore and clinker impact. Custom dimensions are available to fit your conveying equipment.


Galvanized Anti-Rust Rollers
Hot-dip galvanized rollers have outstanding anti-rust and anti-corrosion performance. They are suitable for damp scenarios such as underground mines, outdoor conveyor galleries and coastal aggregate yards to extend service life in humid environments.
HDPE & UHMWPE Plastic Rollers
HDPE and UHMWPE plastic rollers are lightweight, low-noise and wear-resistant. They will not scratch rubber belts and resist chemical corrosion, perfect for cement auxiliary material and corrosive mineral conveying lines. Custom specs are supported.


Impact Roller
Impact rollers are fitted with thick rubber rings to absorb strong impact force. They are installed at all conveyor loading points where large ore and cement clinker fall, protecting belts from crack and tear.
Spiral Return Roller
Also called self-cleaning rollers, spiral return rollers are installed on the return side of belts. Built-in steel spiral strips wipe off sticky clinker, dust and mud on belts to avoid belt deviation caused by material accumulation.


Friction Conveyor Roller
Friction self-align rollers use friction discs on two ends to adjust belt position automatically. Widely used on long-distance cement and mine conveyors, they reduce manual adjustment and keep belts running centered smoothly.
Why Reliable Conveyor Rollers Matter For Your Production Line

We provide full series heavy-duty conveyor rollers for bulk material conveyors: steel conveyor rollers, galvanized anti-rust rollers, HDPE & UHMWPE plastic rollers, impact rollers, spiral return self-cleaning rollers, friction self-align rollers. All rollers fit DTII/TD75 mine & cement belt conveyors, support custom diameter, length and sealing structures.
Impact rollers with rubber buffer rings are only mounted at conveyor loading points where large ore, limestone and cement clinker fall heavily. They absorb strong impact force to avoid rubber belt cracking and tearing, must be matched with standard steel carrying rollers.
Spiral return rollers are installed on the empty return side of conveyor belts. Built-in steel spiral strips scrape sticky cement dust, clinker and mud off belt surfaces, solving belt deviation caused by material buildup, widely used in cement production lines.
Galvanized rollers adopt hot-dip galvanizing anti-corrosion treatment, suitable for damp working conditions: underground mines, open-air conveyor galleries, coastal quarry and wet cement aggregate lines. Ordinary steel rollers will rust quickly in humid environments.
Yes. Our steel conveyor rollers are made of thick seamless steel tube with multi-layer labyrinth dust-proof sealing, strong bearing capacity to withstand continuous impact of ore, stone and cement clinker, standard replacement spare parts for all bulk material belt conveyors.
