1. Basic specifications
models
NZY: center-driven thickener (N thickener, Z center-driven, Y hydraulic rake)
28: pool diameter (28 meters)
Pool depth:3.5-4.2 meters (3.8 meters for conventional design)
Effective se dimentation area: 615
Processing capacity:
Slurry processing capacity: 800-1500m³/h (related to material density and particle size)
Solid handling capacity: 40-80 tons/hour (for ore with a specific gravity of 2.7-3.5)
2.Structure and drive
transmission mode: central hydraulic drive (hydraulic motor + reducer)
Rake lifting mechanism: hydraulic automatic rake lifting (lifting height ≥300mm, overload protection)
Rake frame speed: 0.05-0.15r/min (steplessly adjustable)
Motor power: 7.5-11kW (hydraulic station motor, designed according to load)
3.Materials and anti-corrosion
Pool body material:
concrete structure + epoxy coal tar anti-corrosion (conventional)
or all-steel structure (Q235B + lined with polymer polyethylene board)
Rake frame material: 304 stainless steel or carbon steel rubber lined
scraper material: ultra-high molecular weight polyethylene (UHMWPE) or rubber
4.Applicable working conditions
Feed concentration: 10%-30% solid content (weight ratio)
Underflow concentration: can be concentrated to 40%-70% (adjusted according to material characteristics)
Overflow turbidity: ≤300ppm (can be reduced to below 50ppm when used with flocculants)
5.Equipment size and weight
Machine weight:
Steel structure: ≈45-60 tons (including drive device) Concrete tank body: only the upper structure weighs about 20-30 tons
Overall dimensions (diameter × height): φ28m×4.5m (including drive platform)
6.Optional configurations
Automation control:
Mud level detection (radar or ultrasonic sensor)
Frequency conversion speed regulation + PLC centralized control (automatically adjust the rake speed according to the load)
Auxiliary system:
Flocculant dosing device (to improve sedimentation efficiency) Overflow water recycling system
Key points
1.Factors affecting sedimentation efficiency:
Material density (iron ore slurry sedimentation speed > copper ore slurry)
Particle size distribution (200 mesh proportion > 60% when flocculant needs to be added)
2. Maintenance points:
Regularly check the oil quality of the hydraulic system (it is recommended to replace it every 2000 hours)
Prevent the rake frame from being crushed (the pool needs to be emptied to prevent freezing during winter shutdown)
3. modular design or wear-resistant enhanced versions.
Typical application scenarios
Ore dressing plant: tailings concentration, concentrate dehydration
Coal chemical industry: coal sludge water treatment
Environmental protection project: sewage treatment plant sludge concentration If need a more detailed installation foundation diagram or flocculant ratio recommendation, please provide specific material properties (such as specific gravity, viscosity).
