Sludge Thickener

Introduction

Thickeners are used for dewatering slurries of either tailings or product. A thickener is a large circular tank that is used to settle out the solid material from the water in the feed slurry.It is widely used for dealing with slime, wastewater, waste residue in metallurgy, mine, coal, petrochemical industry, building materials, environmental protection department etc.

Features

1. Deaeration cell is provided to prevent solid particles from attaching to bubbles so that solid particles can fall like a parachute.
2. The mineral-feeding pipe is lower than the pulp surface, it prevents the air to be brought in while feeding.
3. Inner overflow weir is equipped to make the pulp flow on pre-designed route, avoiding short circuit, enlarging the sedimental area.
4. The peg linear is changed from oblique lines to curves. So the discharging underflow has higher density, and treatment capacity is enhanced.

Application

It is widely used for dealing with slime, wastewater, waste residue in metallurgy, mine, coal, petrochemical industry, building materials, environmental protection department etc.

Working principle

The materials are pumped into the feed-well, at the center of the thickener, which is close to the top. The thickened mass is moved toward the bottom center of the thickener by large rakes that rotate around the tank. Rotation speed is very slow, and drive torques can be high, especially for larger diameter thickeners. Drive torque is usually monitored continuously, as high densities could cause failure of the rakes and drive equipment. Rakes may have the capacity to be raised to reduce drive torque. The thickened slurry, also called thickener underflow, is pumped out of the bottom of the thickener.
