What Are Stone Crusher Rollers?

Stone Crusher Rollers are conveyor rollers used in stone crushing, quarrying, and aggregate handling systems to support and guide the conveyor belt while transporting crushed stone and bulk materials. They are designed for continuous operation under demanding conditions involving heavy loads, abrasive materials, dust, vibration, and impact. Depending on the conveyor arrangement, stone crusher systems can use carrying rollers, return rollers, impact rollers, conveyor idler sets, and conveyor brackets. Correct roller selection helps maintain belt alignment, support the conveyed load, reduce belt and bearing wear, and provide smooth material conveying.

How To Select The Right Conveyor Idler Set

Choose the idler set according to conveyor capacity, belt dimensions, material characteristics and operating conditions.

01

Check Belt Width

Select the idler frame and roller length according to the conveyor belt width to provide stable belt support.

02

Determine Conveyor Capacity

Consider required TPH, bulk density and belt speed to determine the roller load and suitable idler arrangement.

03

Select Roller Diameter

Choose roller diameter based on belt speed, load, roller length and required service life. Common sizes range from 76 to 159 mm.

04

Choose Trough Angle

Select 20°, 35° or 45° troughing according to the belt profile, material characteristics and required carrying capacity.

05

Calculate Idler Spacing

Carrying, impact and return spacing should be selected according to belt load, belt tension, material impact and conveyor design.

06

Check Shaft & Bearing

Verify shaft diameter, bearing size and expected radial load before finalizing the idler assembly.

07

Consider Material & Environment

For abrasive, dusty, wet or corrosive environments, select suitable tube material, seals and surface protection.

08

Check Impact Conditions

Where material falls heavily onto the belt, use an impact idler arrangement with suitable spacing and impact protection.

Selection Tip: Final idler selection should be based on belt width, TPH, bulk density, belt speed, material size, trough angle, roller load and conveyor layout.

Troubleshooting

A quick diagnostic path for common conveyor roller issues.
1

Idler Roller Does Not Rotate

Inspect the bearing and seal, remove contamination, and replace the damaged bearing or complete roller if required.

2

Abnormal Roller Noise

Check the bearing condition and seals. Replace worn components and ensure the correct bearing arrangement is used.

3

Excessive Vibration

Check roller runout, shaft condition, mounting bolts, and idler alignment. Replace damaged components.

4

Belt Tracking To One Side

Realign the idler set perpendicular to the conveyor centerline and inspect adjacent idlers.

5

Roller Surface Wear

Check material characteristics and roller specification. Replace excessively worn rollers and review the roller diameter and spacing.

FAQ

A conveyor idler set is an assembly of rollers arranged to support and guide a conveyor belt. Carrying idlers normally support the loaded belt, while return idlers support the empty belt on the return side.

Common arrangements include 2-roll, 3-roll and 5-roll idler sets. The appropriate arrangement depends on belt width, trough angle, material load and conveyor design.

Consider the belt width, conveyor capacity, bulk density, belt speed, roller diameter, trough angle, material size, idler spacing and operating environment.

Common conveyor roller diameters include 76, 89, 102, 108, 114, 127, 133 and 159 mm. The appropriate diameter depends on the belt speed, load and required service life.

Common trough angles are 20°, 35° and 45°. The selection depends on the conveyor design and the characteristics of the conveyed material.
