In sand and gravel aggregate production lines, vibrating screens are one of the core pieces of equipment, undertaking the crucial tasks of material grading, dewatering, and desliming, directly impacting finished product quality and production efficiency. They precisely separate sand and gravel aggregates of different particle sizes through vibration, providing qualified raw materials for subsequent processing, making them indispensable in construction, mining, and other fields. Selecting a vibrating screen requires comprehensive consideration of the application scenario, material characteristics, and equipment performance.

 

1. Scenario

 

Construction waste screening requires high-precision processing, while mining scenarios demand equipment with strong pressure resistance and the ability to withstand high-intensity operations.

 

2. Material Characteristics

 

The particle size, moisture content, and hardness of the material need to be considered; hard ores require wear-resistant screens (such as those made of manganese steel), while sticky materials require a large amplitude design to reduce clogging.

 

3. Equipment Performance

 

Vibration frequency, amplitude, and motor power need to be considered. Furthermore, the choice of screen material is crucial; manganese steel screens have excellent wear resistance, while polyurethane screens are impact-resistant but have lower screening throughput, requiring a trade-off based on the abrasiveness of the material.

 

 

※ Vibrating Screen Recommendations

 

Our YKR series circular vibrating screens and ZKR series linear vibrating screens are specifically designed for sand and gravel aggregates. Both series are made of manganese steel, enhancing equipment durability, adapting to harsh working conditions, and significantly improving screening accuracy and production stability.

 

The YKR series features a multi-layer screen structure (1-4 layers), with a large processing capacity (55-1200 tons/hour), suitable for coarse screening scenarios such as large quarries; its eccentric block excitation design ensures efficient screening and reduces the risk of material blockage.

 

The ZKR series focuses on dewatering and desliming, with a double-layer screen structure (1-2 layers) and a moderate processing capacity (7-500 tons/hour), suitable for wet screening, such as in coal washing plants or humid environments.

 

 

When selecting a vibrating screen, prioritize matching production needs: choose a circular vibrating screen (such as the YKR series) for high-volume scenarios, and a linear vibrating screen for fine screening needs; material characteristics determine the screen material and amplitude parameters.
