Pulp thickener

Introduction

Pulp thickener is suitable for occasions with large processing capacity and low product concentration. It is mainly used for the concentration of concentrates and dewatering of tailings in ore dressing plants.

 

Characteristics

There is a degassing tank in the high-efficiency thickener equipment, which can eliminate the solid particles from adhering to the air bubbles and settle like a "parachute";

Its feeding pipe is designed under the liquid surface to prevent gas from being brought in during the feeding;

The ore sleeve is moved down, and a receiving tray is provided to drop the fed ore slurry evenly and smoothly, effectively preventing the phenomenon of overturning caused by the residual pressure of the ore;

Add an internal overflow weir to make the material flow according to regulations, prevent the phenomenon of "short circuit", and greatly increase the sedimentation area;

The overflow weir of the high-efficiency thickener was changed to a zigzag shape to improve the local suction phenomenon caused by the unevenness of the overflow weir;

The design of the external overflow weir increases the settlement area and is not easy to block materials;

Inclined feeding to eliminate feed blocking problems;

A slow flow device is provided to slow down the rising speed of the material water flow, so that the overflow water is more uniform and the turbidity is lower.

 

Working principle

The high-efficiency pulp thickener is mainly composed of a circular thickening tank and a rake mud scraper. The solid particles suspended in the slurry in the thickening tank settle under the action of gravity, and the upper part becomes clarified water, so that the solid and liquid can be separated and deposited on The slime at the bottom of the concentration tank is continuously scraped and collected by the rake scraper to the central ore outlet at the bottom of the tank, and the clarified water overflows from the upper edge of the concentration tank.
