High Capacity Mining Thickener Dewatering Machine for Mineral Processing Plant

Overview

In almost every mineral processing plant, large volumes of water carry valuable solids through the circuit, and both the water and the solids must eventually be recovered. A thickener concentrates the dilute slurry into a dense underflow and returns clear overflow water to the process, cutting fresh water demand and reducing the load on downstream filters and tailings dams.

The High Capacity Mining Thickener is a large circular tank fitted with a central drive and a rotating rake mechanism. Feed slurry is mixed with flocculant in a feedwell so that fine particles gather into fast settling flocs, which sink to the bottom and are raked toward the centre discharge. Clear supernatant rises to the top and is collected at the overflow launder.

The rake drive is equipped with an automatic lifting device that raises the rakes if the torque rises too high, protecting the mechanism from overload. This makes the thickener reliable even when the feed density or the ore type changes, and it keeps the underflow dense enough for efficient dewatering and backfill.

Key Features
  • High Rate Settling: A flocculant feedwell and a large settling area give a compact, high capacity unit with a small footprint.
  • Automatic Rake Lift: A torque sensing drive automatically lifts the rakes when solids build up, preventing overload and costly downtime.
  • Dense Underflow: Careful rake design and discharge control produce an underflow concentration up to 70 percent solids for efficient dewatering.
  • Clear Overflow Water: Low overflow turbidity lets the clarified water be recycled directly to the grinding and flotation circuit.
  • Robust Drive Unit: A heavy duty gearbox and bearings, built for continuous duty, keep the thickener running reliably 24 hours a day.
  • Flexible Construction: Available in steel tank or concrete tank versions to suit the site conditions and the customer preference.
