Screening Systems
Effective screening is crucial for separating different aggregate sizes and ensuring product quality. A complete gravel crusher system typically incorporates multiple screening stages, including pre-screening before secondary crushing and final product classification. Vibrating screens with various deck configurations allow for precise separation of materials into specific size fractions such as 0-5 mm manufactured sand, 5-10 mm fine gravel, and 10-20 mm standard aggregate. The modular design of modern screening equipment enables easy maintenance and quick screen media changes to accommodate different production requirements.
Washing and Classification Equipment
For applications requiring clean, dust-free aggregates, washing equipment is essential. Modern washing systems combine three functions: cleaning, dehydration, and impurity removal to produce high-quality final products. Sand washing machines and log washers effectively remove clay, silt, and other contaminants that can compromise aggregate performance in construction applications. These systems are particularly important for producing concrete sand and fine aggregates where cleanliness directly impacts the final product strength and durability.
