1. Key Application Scenarios and Buffering Requirements for Conveyors

Conveyors are widely used in modern industrial scenarios. Under the original layout, details have been optimized based on the following practical application scenarios:

1.1 High Impact Loading Area (Optimized Belt and Drum)

• At the feeding point (discharge port) of the conveyor, use high elasticity and wear-resistant belts to minimize friction and prevent belt wear and heating;
• The elastic belt at the transfer point below the crusher and screening machine can effectively reduce the impact force of material discharge;
• High drop unloading area (drop>2m), control the unloading speed, and the elastic belt can reduce the impact force of unloading.

1.2 Special Material Handling Conditions (High Impact and High Quality + Irregular Shape)

Typical Materials: Large ore/rock transportation (particle size>300mm); Sharp materials (metal waste, crushed stones); Heavy materials (iron ore, steel slag).

The transportation of the above materials can easily cause the following problems:

1. The unstable center of gravity of the conveyor can easily cause conveyor malfunctions;
2. Easy to cause belt wear on the conveyor;
3. The discharge port is prone to damaging the loading tool;
4. Conveyors are susceptible to significant impact forces when receiving materials.

1.3 Application in Harsh Environments

Typical Scenarios: Port loading and unloading systems (high throughput); Main transportation line of the mine (continuous operation); High temperature material area in steel metallurgy.

The limitations of loading, unloading, and maintenance of conveyors make maintenance difficult in these application scenarios, requiring strict assurance of the quality and maintenance time of the conveyor. This places high demands on the main components, such as conveyor rollers (buffer rollers, groove type bearing rollers, self-aligning friction rollers, etc.)

2. Main Classification and Technical Characteristics of Buffer Rollers

The composition and classification of buffer rollers are as follows. Different compositions and classifications have different application scenarios.

2.1 Comparison of Structural Classification

2.2 Classification of Groove Types

• 35° Groove Type Buffer Group - Universal bulk material;
• Buffer Flat Roller - Bagged/packaged materials;
• V-shaped Buffer Roller - Anti-deviation design.

3. Five Step Method for Selecting the Best Buffer Roller

Buffer rollers are selected according to different needs. The following is the best method for selecting buffer rollers based on years of experience:

4. Core Points of Installation and Maintenance

Installation Specifications

• Distance from the feeding point: 1-1.5 times the bandwidth;
• Transition zone setting: 3-5 sets of transition rollers at the front and back respectively;
• Installation angle error: <0.5°.

Maintenance Cycle

• Daily inspection: Abnormal bearing noise, rubber wear;
• Regular maintenance: 6-month lubrication inspection;
• Preventive replacement: Rubber parts have a 3-5 year replacement cycle.

5. Recommended Configurations for Industry Applications

Heavy Load Working Conditions in Mines

• Preferred: Heavy duty spring plate buffer bed;
• Configuration: 45° groove angle, ceramic coating;
• Spacing: 50% -70% of the normal spacing.

Port Loading and Unloading System

• Preferred: Articulated buffer group;
• Configuration: Anti-corrosion coating, self-cleaning design;
• Monitoring: Integrated impact force sensor.

Food Light Industry

• Preferred: Stainless steel polyurethane roller;
• Configuration: Food grade materials, hygienic design;
• Certification: FDA/HACCP Compliance.
