How it works

Monitored machines — interactive

Mill, slurry pump, conveyor gearbox — the machines that stop a plant. Spin the models: cyan dots mark vibration sensor locations; drive current is taken by CTs in the cabinet, with no shutdown.

3D Spin the models — measurement points are marked

Effect: Trunnions, girth gear and drive under watch — a mill stop never comes “out of nowhere”.

By process stage

Where Liman-Tech applies — stage by stage

For each stage: the equipment worth monitoring and what each method delivers. No fluff.

1

Extraction and primary haulage

Equipment
Drill rigs, excavators, conveyors, feeders, transfer points, primary-intake crushers
Vibro Conveyor drives, gearboxes, drums, idlers, vibrating feeders, crushers, drive motors
Current Motors on conveyors, crushers, feeders, hydraulic-system pumps
APC Optimizing ore feed to crushing, coordinating feeder–crusher–conveyor
Effect: Even feed, fewer crusher overloads, a steady flow down the chain
2

Crushing (primary → tertiary)

Equipment
Jaw / cone / gyratory crushers, roll crushers, screens, bins, hydraulic power units
Vibro Crusher drives, bearings, gearboxes, screens, hydraulic units, lubrication pumps
Current Main crusher motors, screen and conveyor motors, lubrication pumps
APC Controlling feed to the crusher, circulating load, coordinating crusher–screen–conveyor
Effect: Stable particle size, fewer overloads and emergency stops
3

Grinding (mills)

Equipment
SAG mills, ball and rod mills, drives and gearboxes, slurry pumps, hydrocyclones
Vibro Support bearings, gearboxes, girth gear and pinion, slurry pumps, oil units
Current Mill, slurry-pump and classifier motors
APC Mill power, ore / water / grinding-media feed, hydrocyclone regime, slurry density, circulating load
Effect: Higher throughput (+3–5% on APC benchmarks), stable particle size, lower specific energy
4

Flotation

Equipment
Flotation cells, agitators, blowers, compressors, pumps, reagent dosing stations, machine-vision cameras on froth
Vibro Blowers, compressors, slurry and reagent pumps, agitator gearboxes, flotation-cell drives
Current Motors on blowers, pumps, agitators, dosing units
APC Air flow, cell levels, reagent dosing, feed density, agitator speeds
CV Froth parameters from computer vision (CV froth analysis on Larus-1000)
Effect: Higher recovery (+2–3 pp), more consistent concentrate grade, −10–15% reagent consumption
5

Classification, thickening, filtration, water circuit

Equipment
Hydrocyclones, slurry pumps, thickeners, vacuum and pressure filters, tailings pumps, recycled-water pumps
Vibro Pumps, agitators, thickener gearboxes, filtration drives
Current Pump and agitator motors
APC Cyclone pressure, underflow density, flocculant dosing, filtration cycles, recycled-water balance
Effect: Stable tailings operations, fewer incidents, better water management
Strongest combinations

Where combined methods multiply the effect

Crushing
Vibration + Current + APC
Grinding
Vibration + Current + APC
Flotation
Vibration + Current + APC + CV
CV froth analysis on Larus-1000 — the strongest multiplicative effect.

What we offer

Three rollout levels — pick by maturity

Level 1

Equipment reliability

Critical machines across stages: mills, crushers, pumps, blowers

Stack
Passer (vibration + current) + Larus + diagnostics on Strix
Level 2

Process transparency

Monitoring, alarms, KPIs per asset

Stack
Larus + Strix
Level 3

Optimization

Grinding, flotation, thickening

Stack
Strix APC — soft sensors, CV froth analysis, predictive loops

Results in numbers

  • +2–3 pp flotation recovery with APC and froth video analytics
  • −10–15% specific consumption of collector reagents
  • −30% spread in concentrate grade (consistency)
  • +3–5% grinding throughput under APC control

Industry benchmarks; your actual results follow a site assessment at your operation.

We know this industry deeply: through R&D partnerships with ITMO University (Fedot.Industrial for flotation APC), HSE University and Polytech (our own lab), the methods are validated on real data — not just in desk models.

Proven case

A major Russian gold producer — vibration monitoring of process equipment across four gold processing plants: mills, crushers, slurry pumps — in industrial operation.

How to buy

Three commercial models

From outright purchase to a service model where you pay out of verified savings.

CAPEX — purchase

You own the hardware and software — the full effect is yours. Transparent and familiar; for critical infrastructure it is the only option.

MaaS — subscription

Monitoring-as-a-Service: 36 months, a monthly base fee plus a share of the verified effect. The performance risk is ours — no effect, nothing beyond the base.

ESCO — energy performance contract

Energy-saving measures with no capital outlay on your side: we invest, repayment comes out of verified savings.
