Key Benefits for Thickening and Water Recovery Projects
Use this product when a project needs stable slurry concentration, clarified water recovery, and reliable underflow control before filtration or tailings discharge.
High-efficiency Settling
Tank structure and feed design help improve settling and concentrate bottom flow toward the discharge center.
Process Water Recovery
Clarified overflow can be collected for reuse, helping reduce fresh-water demand in suitable processes.
Stable Underflow Density
Rake concentration and discharge control support stable downstream filtration or dry discharge.
Automatic Rake Lifting
Hydraulic rake lifting and overload protection help protect the drive system when resistance increases.
Heavy-duty Structure
Central drive, circular tank, rake arm, bridge, and underflow system are configured for industrial use.
Downstream Process Support
Thickened slurry can support ceramic filtration, belt filtration, pressure filtration, or tailings handling.
Applications in Mining Slurry Thickening
NGZ High Efficiency Thickener is used before filtration, dry discharge, or water recycling steps where slurry concentration and clarified overflow matter.
Tailings Thickening
For tailings concentration before filtration, dry discharge, backfill, or water recovery.
Discuss Application →Concentrate Thickening
For improving feed concentration before downstream filtration or transport.
Discuss Application →Hydrometallurgy Slurry
For leaching, residue, and process slurry concentration where continuous thickening is required.
Discuss Application →Environmental Water Recovery
For industrial slurry clarification and recovery of process water under suitable conditions.
Discuss Application →Working Principle
Slurry enters the thickener feed area and settles under gravity, often with process conditioning where required. Clarified water overflows from the top while the rake mechanism moves settled solids toward the center for underflow discharge.
Slurry Feeding
Slurry enters the central feed area for controlled distribution.
Settling
Solids settle while liquid rises toward the overflow area.
Clarified Overflow
Clarified liquid is collected from the upper overflow channel.
Rake Concentration
Rake arms move settled solids toward the center.
Underflow Discharge
Concentrated slurry is discharged from the bottom outlet.
Rake Protection
Hydraulic lifting protects the rake when resistance increases.
Main Structure and Components
The NGZ Thickener includes the tank body, feed well, central drive, rake mechanism, hydraulic lifting system, overflow launder, underflow outlet, and control system.
Circular Tank Body
Tank shape, bottom slope, and compression zone support slurry settling and concentration.
Central Drive System
Central drive rotates the rake mechanism and supports continuous underflow collection.
Rake Mechanism
Rake arms scrape settled solids toward the center discharge area.
Hydraulic Lifting
Hydraulic rake lifting helps protect the drive system under high resistance.
Overflow Launder
Clarified overflow is collected for recycling or downstream process use.
Underflow Discharge
Concentrated underflow is discharged for filtration, backfill, or dry discharge process.
Bridge and Platform
Bridge, platform, and safety access support operation and inspection.

Technical Specifications
NGZ High Efficiency Thickeners are configured by tank size, material behavior, feed concentration, required underflow density, overflow clarity, and project layout.
| Selection Item | Reference Configuration | Typical Selection Basis |
|---|---|---|
| Tank Body | Variable slope or deep cone option | Selected by slurry settling behavior and underflow concentration target |
| Drive and Rake | Central drive with automatic rake lifting | Selected by resistance, solids loading, and safety requirement |
| Process Result | High underflow concentration under suitable conditions | Final result depends on material test, flocculant, feed stability, and operation |
Tank size, drive power, rake lifting and protection functions, overflow quality, and underflow density are confirmed from the slurry data and project requirements.
