apron conveyor feeder granite

Granite Crushing and Sand Making Production Line

A complete granite processing line typically includes apron feeders, jaw crushers, cone crushers, vibrating screens, and sand-making machines. The apron conveyor feeder plays a critical role in uniformly feeding raw granite blocks (≤800mm) into primary crushing equipment.

<h2key considerations<h2<• feed size control: apron feeders should maintain ≤30mm gap to prevent material leakage
• wear protection: manganese steel liners (≥18mm thickness) for abrasive granite
• moisture tolerance: up to 15% wet material handling capacity

<h2faq section<h2<strongq: what's the typical output gradation?<strong<
a: 0-5mm (40%), 5-10mm (30%), 10-20mm (20%), 20-31.5mm (10%)

<strongq: how to reduce dust pollution?<strong<
a: recommend water spray systems (+3% moisture content) and pulse bag filters
