Spiral Classifier

Liming Heavy Industry‌, a pioneer in mining and mineral processing equipment, presents its high-efficiency ‌Spiral Classifier‌—a robust and reliable solution for material classification, dewatering, and washing. Designed to seamlessly integrate with grinding circuits, Liming’s Spiral Classifier ensures precise separation of coarse and fine particles, enhancing the efficiency of mineral processing plants. Built for durability, low maintenance, and adaptability, this equipment is ideal for handling ores, sand, slag, and other materials in mining, construction, and industrial applications.

Product Overview

Liming’s ‌Spiral Classifier‌ employs a rotating spiral mechanism to separate materials based on particle size or density. Its advanced design ensures efficient lifting of coarse particles for regrinding while discharging fine particles and slimes. Available in high-weir, submerged, or dual-pitch configurations, this classifier excels in both dry and wet processing environments. Whether used in closed-circuit grinding, sand washing, or mineral dewatering, Liming’s Spiral Classifier guarantees high classification accuracy, low energy consumption, and long-term reliability, making it indispensable for modern mineral processing operations.
