Gravity Thickener

Gravity thickener is a solid-liquid separation equipment based on gravity settlement, which is similar to clarifier and sedimentation tank. It can make suspended solids in the slurry gradually sink to the bottom of the tank.

LZZG series introduced products to absorb foreign advanced technology, and designed combined with sand field actual situation. It can effectively reduce the loss amounts of fine material; solve problems of end product such as relatively high fineness modulus and relatively low stone powder content. The fine material can be recycled as high as 95%, with incomparable technical and economic advantages.

Details Introduction

A gravity thickener is a solid-liquid separation device that operates on the principle of gravity settlement, functioning similarly to clarifiers and sedimentation tanks. It facilitates the gradual settling of suspended solids in slurry to the bottom of the tank.

Gravity thickeners are widely employed in mining, metallurgy, and other industries for processing various minerals, metals, and non-metals. Additionally, they are utilized in industrial wastewater treatment, environmental protection, and related fields.

Working Principle
During operation, the slurry is mixed with flocculant and fed into the gravity thickener via the central cylinder. A guide plate at the outlet of the feed vertical cylinder directs the slurry from the center to the surrounding areas, allowing it to diffuse evenly.

Through gravity settling, a gravity thickener can concentrate slurry with a solid content of 10%–20% into underflow slurry with a solid content of 45%–55%. Assisted by an internal rake mechanism, the thickened underflow slurry is discharged through the thickener’s underflow port. Meanwhile, the clarified water from the upper layer exits via the top drainage outlet, achieving effective mud-water separation.

Features
1. High processing capacity per unit volume and superior concentration efficiency.

2. Hydraulic multi-point drive with infinite speed regulation, high mechanical strength, and built-in overload protection.

3. Equipped with a hydraulic rake lifting device for reliable operation.
