EPC Supply for a Single Line Fine Crushing and Screening Line for Limestone High Capacity and High Precision

Complete Production Line for Four Categories of High-Value-Added Specialty Aggregates Limestone Production Line Project Overview This solution is a single-line limestone crushing and screening system with a capacity of 3,000 metric tons per hour. It employs a single PCZ2125 heavy-duty hammer crusher for primary crushing, followed by a closed-circuit process involving two PC1622 shaping crushers, and two sets of four-stage fine screening using eight 2YKZ40100 extra-wide double-deck vibrating screens. The system produces four product categories: 1–3 mm aggregate, 1–2 mm aggregate, crushed limestone flakes (also known as “melon seed stone”), and limestone powder, covering the full range of fine-grained specialty sand and gravel. It targets high-value-added niche markets such as dry-mixed mortar, asphalt concrete, and decorative building materials. Core Challenges: For a 3,000-metric-ton-class high-capacity fine-grain product line, the insufficient width of conventional screens (typically…
