Core Equipment Configuration

A properly designed gravel processing plant requires careful selection of equipment that works harmoniously together. The standard configuration includes:

• Primary Crushing: C6X Series Jaw Crusher for initial size reduction
• Secondary Crushing: CI5X Series Impact Crusher for medium crushing
• Tertiary Crushing: VSI6X Series Vertical Shaft Impact Crusher for final shaping
• Screening: S5X Series Vibrating Screen for precise particle separation
• Washing: XSD Series Sand Washer for final product cleaning

Gravel Characteristics and Processing Requirements

Understanding gravel properties is essential for proper equipment selection and plant design. Gravel typically consists of rock fragments ranging from 2mm to 75mm in diameter, with varying degrees of hardness, abrasiveness, and moisture content. These characteristics significantly influence processing requirements.

Gravel from riverbed deposits generally contains rounded particles with minimal clay content, requiring less aggressive crushing but more thorough washing. In contrast, quarry-run gravel often contains angular particles with higher clay content, demanding more robust crushing equipment and pre-screening systems. The hardness of the parent rock (measured on the Mohs scale) determines wear rates on crusher components and energy consumption patterns.
