What is a Thickener?

High Efficiency Concentrator

Concentrate Thickener definition:

Thickener (also known as thickener or agitator) is suitable for concentrate and tailings dehydration treatment during the beneficiation process to increase the slurry concentration from 20-30% to 40-70%.

It is of great significance to improve the utilization rate of backwater, the concentration of bottom flow and protect the environment.

In fact, the high efficiency concentrator is not a kind of simple sedimentation equipment, but a new type of dehydration equipment combined with the characteristics of mud layer filtration.

It is divided into central transmission type, peripheral transmission type, sludge, intermittent type, vertical flow and continuous thickener.

A thickener is a device used to separate solids from liquids in a slurry, increasing the solids concentration.

It is a crucial step in mineral processing, wastewater treatment, and other industries. A concentrate thickener specifically increases the solids concentration of mineral concentrates before further processing, like filtration or tailings disposal.

The goal is efficient sludge thickening.

What is the Structure of Efficient Thickener?

An efficient thickener typically consists of:

  • Feedwell: Introduces the slurry into the thickener, promoting gentle flocculation.
  • Tank: A circular tank where solids settle to the bottom.
  • Rake Mechanism: Moves settled solids to the center discharge point.
  • Underflow Pumping System: Removes the concentrated slurry from the bottom of the tank.
  • Overflow Weir: Collects the clarified water from the top of the tank.
  • Mekanismo ng Pagmaneho: Powers the rake system and ensures efficient solids transport.
  • Control System: Monitors and adjusts process parameters.
High Efficiency Concentrator structure

The structure of our slurry thickener contributes to efficient sludge thickening. The high efficiency concentrator generally consists of the thickener pool, transmission device, lifting device, feeding device, unloading device and signal safety device. The main feature of this machine is to add a certain amount of flocculant to the pulp to be concentrated, so that the ore particles in the pulp will form flocculation groups and accelerate its settlement rate, so as to improve the concentration efficiency.

How Does the Gravity Thickening Equipment Work? Thickener work principle

Gravity thickening equipment works based on the principle of gravity settling. The slurry enters the thickener through the feedwell, where flocculants are added to promote the aggregation of fine particles. The aggregated particles settle to the bottom of the tank, forming a concentrated slurry. The clarified water rises to the top and is discharged over the overflow weir. The rake mechanism moves the settled solids to the center discharge point, from where it is pumped out as underflow. This is the core of pampalapot.

High Efficiency Concentrator work principle

Ang prinsipyo ng pagtatrabaho ng isang high-efficiency concentrator ay nagsasangkot ng dalawang pangunahing aspeto: pagtaas ng laki ng solid particle at pagpapalawak ng settlement area.

Ang pagtaas ng laki ng solid particle sa slurry at ang settlement area ng high-efficiency concentrator ay maaaring mapabuti ang processing capacity ng high-efficiency concentrator. Maaaring dagdagan ang laki ng butil ng mga settling particle sa pamamagitan ng pagdaragdag ng flocculant sa high-efficiency concentrator upang gawing agglomerate ang mga pinong particle. Ang hilig na plato sa high-efficiency concentrator ay maaaring pataasin ang settlement area, paikliin ang settlement distance ng mga particle at mapabuti ang concentration efficiency. Ang pagsubok at pang-industriya na produksyon ay nagpapakita na sa ilalim ng parehong kapasidad sa pagpoproseso, ang diameter ng high-efficiency na pampalapot ay dalawang-katlo hanggang kalahati lamang ng diameter ng ordinaryong pampalapot, at ang lugar ay humigit-kumulang isang-siyam hanggang ika-apat na bahagi ng ordinaryong pampalapot, habang ang kapasidad ng pagproseso sa bawat unit area ay maaaring tumaas ng ilang beses hanggang dose-dosenang beses.

Why is the Concentrate Thickener Efficient?

Concentrate thickeners are efficient due to several design features:

  • Optimized Feedwell Design: Promotes gentle flocculation and minimizes turbulence.
  • Large Settling Area: Provides ample space for solids to settle, increasing throughput.
  • Efficient Rake Mechanism: Moves solids to the discharge point without disturbing the settled bed.
  • Automated Control System: Maintains optimal process parameters, ensuring consistent performance.

PAG-ZONEDING thickeners incorporate these features, making them highly efficient in solids recovery and water conservation.

FAQ

Question 1: What is the difference between a thickener and a clarifier?
A thickener primarily increases the solids concentration of a slurry, while a clarifier removes suspended solids from a liquid to produce a clear effluent. They both are clarifiers and thickeners.
Question 2: What is the role of flocculant in the thickening process?
Flocculant is added to the slurry to promote the aggregation of fine particles, which enhances settling and increases the settling rate.
Question 3: How do I control the underflow density in a thickener?
Underflow density can be controlled by adjusting the underflow pump speed, rake lifting mechanism, and flocculant dosage. You can find the right underflow density control.
Question 4: What is the typical residence time in a thickener?
The typical residence time in a thickener ranges from 2 to 8 hours, depending on the slurry characteristics and throughput requirements.
Question 5: How often should I replace the rake blades in a thickener?
The frequency of rake blade replacement depends on the abrasiveness of the slurry and the operating conditions. Regular inspection helps to determine when replacement is necessary.
Question 6: Can I use a thickener for multiple types of mineral concentrates?
Yes, but the thickener may need to be adjusted to optimize performance for different slurry characteristics.
Question 7: What is the energy consumption of a high-efficiency thickener?
The energy consumption depends on the size and design of the thickener. High-efficiency thickeners typically consume less energy per ton of solids processed compared to conventional designs.
