Product features

Assists in conveyor belt direction changing and guiding

The head discharge drum is the main direction-changing component of the conveyor belt, while the pulleys play an auxiliary guiding role, restricting the lateral swing of the conveyor belt during the direction-changing process, ensuring the conveyor belt fits closely to the drum surface, preventing the conveyor belt edge from rubbing against the drum end covers and frame, and reducing belt edge wear.

Fine-tune the conveyor belt tension

Some pulleys are equipped with adjustable brackets; by adjusting the installation height or horizontal position of the pulleys, the wrap angle and tension of the conveyor belt can be slightly changed, solving the problem of slack and slipping caused by conveyor belt elongation and ensuring the effective transmission of driving force from the discharge drum.

Optimize discharging effect and prevent material adhesion

Pulleys mounted above the drum can slightly press down the conveyor belt, creating a certain curvature for the belt during discharging to facilitate rapid material separation from the belt and reduce the probability of material adhesion to the belt surface; they also prevent excessive vibration of the conveyor belt caused by discharging impact.

Compact structure, suitable for head space layout

Main structure: Composed of pulley roller, bearing housing and mounting bracket. The roller diameter is usually 80~150mm (selected according to the conveyor belt width), adopting a lightweight design to adapt to the limited installation space at the head discharge end;

Material selection:

Low running resistance, conveyor belt-friendly

The pulley adopts sealed deep groove ball bearings for flexible rotation, realizing rolling friction with the conveyor belt. Its running resistance is far lower than that of sliding friction, which will not add extra driving load to the conveyor; the elastic coating can buffer the contact pressure and prevent scratches on the conveyor belt surface.

Flexible installation and adjustment, high versatility

The brackets are mostly designed with chute or hinged structures, enabling two-way adjustment of height and horizontal position, and are suitable for the head discharge stations of conveyors with different belt widths (500~2200mm);

The mounting hole positions comply with industry standards, which can be matched with the head drum frames of different manufacturers, and can be installed or replaced without large-scale modification.

Easy maintenance and low failure rate

Sealed bearings are dustproof and waterproof, requiring no frequent grease filling with a maintenance cycle of 6~12 months; the worn pulley roller can be replaced individually without disassembling the entire bracket, reducing operation and maintenance costs.

The installation position and height must be precisely controlled

The pulley must be kept parallel to the head discharge drum, and the roller surface should be perpendicular to the center line of the conveyor belt to prevent unilateral wear of the conveyor belt.

The contact pressure between the pulley and the conveyor belt must be moderate; excessive pressure may cause over-stretching of the conveyor belt, while insufficient pressure will fail to achieve guiding and tensioning effects. The general standard is that the conveyor belt has no obvious slack and no deviation.

Overloading or subjecting to impact loads is strictly prohibited.

The pulley has a limited load-bearing capacity and cannot be used as a load-bearing component; a buffer device must be installed at the feed inlet to prevent materials from directly impacting the pulley, which may cause roller deformation or bearing damage.

Regularly inspect the operating status

Inspect the flexible rotation of the pulley regularly for abnormal noise or jamming. If the bearing is damaged, replace it in a timely manner to prevent the rolling friction from turning into sliding friction and scorching the conveyor belt.

Check whether the fixing bolts of the bracket are loose to prevent pulley displacement from causing conveyor belt deviation; clean the materials adhering to the roller surface to avoid affecting the guiding effect.

Use in conjunction with the head sweeper

The pulley cannot replace the function of a sweeper. A conveyor belt sweeper must be installed behind the head discharge drum to promptly clean residual materials on the belt surface and prevent damage caused by materials being pinched between the pulley and the conveyor belt.

Product Specification

The following points shall be noted when selecting and purchasing conveyor rollers:

1. Is a double-ended shaft or keyway required?

Confirm the specifications and quantity of keyways according to the overall transmission design of the machine.

2. What is the product delivery time?

Regular stock available / 7~15 days for customization; specific lead time to be confirmed for large-batch customization.

3. Are samples/drawing confirmation provided?

For customized non-standard rollers, the drawings must be confirmed first to avoid processing errors.

4. What is the product warranty period?

The standard warranty period is 1 to 2 years, with the warranty scope to be confirmed (e.g., whether bearing seizure and rubber lagging detachment are covered by repair or replacement).

5. Is installation guidance and technical drawings provided?

Such as installation drawings, dimension drawings, and bearing model drawings?

Supplementary: Key questioning focuses for different working conditions

6.High-temperature coke/ore working conditions?

Focus on asking about high-temperature resistant materials (roller body/bearing), hot vulcanized rubber lagging thickness, high-temperature resistant grease, and labyrinth seals.

7. Corrosive chemical working conditions?

Focus on asking about roller body materials (304/316 stainless steel), shaft head anti-corrosion treatment, fluororubber seals, and stainless steel bearings.

8. Grain/powder material working conditions?

Focus on asking about surface smoothness (anti-adhesion), dust-proof sealing, and light-load low-noise bearings.

9.High-inclination/heavy-duty working conditions?

Focus on asking about roller wall thickness, shaft diameter material, ceramic lagging (anti-slip), rated tension, and dynamic balance grade.
