About WeirFlow Mining

From slurry evidence to a more predictable mineral-processing plant.

WeirFlow Mining is built for teams that want documented engineering decisions: pump duty, cyclone cut point, crusher wear, screening efficiency and parts readiness all connected in one technical file.

Operating roadmap

Four workstreams guide every WeirFlow Mining project.

Duty Evidence

  • Gather solids SG, pH, PSD and head data.
  • Compare actual duty against pump curve.
  • Record assumptions for plant review.

Wear Discipline

  • Measure liner and impeller profiles.
  • Select wet-end material by abrasion mode.
  • Track wear trend between shutdowns.

Classification Control

  • Model cyclone cut point and pressure.
  • Inspect apex and vortex finder wear.
  • Review circulating load before changes.

Shutdown Readiness

  • Rank critical spares by bottleneck impact.
  • Pre-stage wear kits and seal kits.
  • Close work orders with traceable reports.

Milestones that shaped our engineering desk

  1. 2016

    First integrated pump and cyclone audit for a copper concentrator with recurring overflow instability.

  2. 2018

    Built a wet-end material comparison library for high-chrome, rubber, polyurethane and ceramic-lined duties.

  3. 2020

    Introduced liner-life documentation for jaw and cone circuits tied to planned shutdown windows.

  4. 2023

    Expanded remote review packs for mines that needed engineering support before field access was approved.

  5. 2026

    Standardized one combined circuit report for slurry transport, classification and crushing bottlenecks.

Our value is not simply supplying parts. A plant loses money when a pump, cyclone, crusher or screen is treated as an isolated object. A slurry pump running outside its curve can distort cyclone pressure. A cyclone with worn apex parts can overload downstream classification. A crusher liner kept too long can move the bottleneck into screening. WeirFlow Mining uses a more connected method: document the process data, identify the bottleneck, choose materials and service steps that fit the duty, then leave the site team with records they can use at the next shutdown meeting.

Put a disciplined engineering file behind your next plant change.

Share a duty point, a wear problem or a shutdown target. We will help define the scope before you commit the maintenance window.
