Stator (Cover Plate) ＆ Rotor (Impeller)
Product Description :
PUTECH stators adopt floating annular diversion structure with precise matching to rotors, stabilizing slurry flow field, eliminating vortexes and evenly diffusing bubbles to raise aeration volume and mineralization efficiency for steady flotation performance. Customizable based on technical drawings.
Specifications
Common Types: Vane stator, louver grid stator
Preferred Material: Polyurethane (PU) — high abrasion resistance, acid & alkali resistance, smooth non-stick surface, ideal for fine-grained and corrosive slurry. Match rotor material for synchronized wear to cut maintenance shutdowns.
Main Wear Zones
1. Inner diversion surface & vanes: Fastest wear from high-speed slurry scouring ejected by rotors
2. Holes & vane edges: Corners wear thin and form notches/perforations first
3. Fixed joints: Looseness & abrasion from long-term vibration + slurry erosion
Failures Caused by Wear
1. Worn diversion surfaces → turbulent flow, severe foaming, enlarged bubbles
2. Oversized clearances & pores → reduced air intake, lower separation efficiency, higher reagent consumption
3. Local perforation & damage → slurry bias flow, excessive settled sand, deteriorated overall performance
Inspection & Replacement Standard
Inspection Cycle: Inspect synchronously with rotors every 1,000–2,000 operating hours
Replacement Criteria:
1. Vane/diversion surface wear exceeds 1/3 of original thickness
2. Perforations, large notches or liner peeling/cracking appear
3. Severe foaming, insufficient aeration or excessive vibration persists after clearance adjustment
Maintenance Tips
1. Ensure coaxial installation with uniform surrounding gaps to avoid unilateral uneven wear
2. Prevent iron blocks & large debris from entering rotor-stator gaps to avoid collision damage or jamming
3. PU/rubber components shall avoid long-term high temperature and strong chemical solvents to slow aging
