Thickeners

Thickeners are gravity-based solid-liquid separation units designed to increase slurry density by allowing solids to settle while recovering clarified water. They are widely used in mineral processing, tailings management, and wastewater treatment applications.
Engineering Overview
Metzix high-rate and conventional thickeners provide high-performance solid-liquid separation engineered for heavy industrial duties. Operating on gravity sedimentation principles enhanced with optimized flocculant dosing, these units accelerate the settling velocity of ultra-fine particles, yielding high-density underflow slurries and optical-grade clarified water. Built with high-torque center-drive mechanisms, automated rake lifting assemblies, and heavy-duty bridge structures, Metzix thickeners deliver maximum thickening rates with minimal floor space requirements across mining, aggregate, and industrial wastewater plants.
