Cyclone feed lines are critical for delivering high-velocity slurry from the pump to hydrocyclones — and they take a beating. Operating under high pressure with tight bends and extreme flow, they’re one of the most failure-prone areas in any circuit.
Whether you’re managing a grinding circuit, flotation feed or tailings, Beaver’s engineered cyclone feed line systems are built to last.
Common Cyclone Feed Issues
Abrasion
The highest wear in cyclone feed lines occurs in the bends and at the pump discharge spool. When high-velocity slurry exits the pump, it hits the outer wall of tight-radius bends, creating turbulent zones that erode the liner. These hotspots can quickly thin the pipe wall and lead to leaks or complete failure. The discharge spool, often a short reducer, is especially prone to wear due to both turbulence and vibration.
Misalignment
Cyclone feed lines often shift due to plant settlement, vibration, or installation issues. Rigid steel spools can’t take up this movement, creating stress points and frequent failures. Slurryflex hoses solve this by flexing to absorb misalignment. They fit quickly, save shutdown time, and cut the risk of leaks – keeping cyclone feed systems reliable and online.
Vibration
High-energy slurry flow and pump action create vibration that stresses rigid steel piping. Over time, this vibration loosens joints, accelerates wear, and causes costly unplanned downtime. Slurryflex hoses act as vibration dampeners, absorbing movement before it damages adjoining pipework, valves, or pumps. The result is a more reliable cyclone feed system with fewer shutdowns.
Velocity Errors
Incorrect pipe sizing or sharp bends in cyclone feeds create velocity hotspots where slurry impinges, eroding liners quickly. These “velocity errors” shorten wear life and force repeated fixes. Beaver addresses this with Abrasiguard lined spools, severe-duty hoses, and SlurryIQ audits that re-engineer layouts to reduce turbulence, extend wear life, and ensure feed lines last through shutdown cycles.
How Beaver Solves the Cyclone Feed Line Problem
Beaver designs feed lines that last longer and perform better than standard piping.
1. Replace Sharp Bends with Long Sweeping Curves
We replace sharp feedline elbows with long sweeping curves to minimise slurry strike. This design change reduces liner erosion and extends service life.
2. Use Flexible Slurryflex Hoses
Instead of rigid spools, we install Slurryflex hoses that flex with movement, reduce flange stress, and simplify installation. They’re reinforced with a wire helix for strength.
3. Upgrade Linings for Longer Wear Life
We use Slurryflex ceramic-lined hoses for elbows and Abrasiguard polyurethane spools for straights. These materials last up to 10× longer than rubber-lined or HDPE pipe.
4. Install Smarter Valves and Reducers
We fit CMO knife gate valves and AB Series air valves for better control and abrasion resistance. A flexible reducer at the pump discharge absorbs turbulence and vibration.
