The oil tells us first. So we tell you first.

Scheduled oil sampling and analysis on your cones, screens and plant equipment. Every month you get a two-page report that leads with the verdict.

The problem

The machine tells you last.

When a cone or a screen goes down without warning, the plant stops. Trucks wait, the crew stands around, and parts get bought at rush prices.

Bearings and bushings don't fail all at once. Iron and copper show up in the oil first, while the machine still sounds fine. Sample on a schedule, watch the trend, and the repair gets planned instead of forced on you.

What we do

Three things, done every month.

Oil sampling and analysis

Samples pulled from your crushers, screens and plant equipment on a set schedule. Analysis runs through an independent oil lab.

Verdict-first reports

One report a month. Two pages max. The verdict and the action are at the top, and every reading is checked against the alarm limits in the OEM manual.

Bolt-on field service

Oil and filter changes, sampling, and basic servicing of power units, done on site.

How it works

From site walk to phone call.

  1. Site walk and sample point setup

    We walk the plant with you, pick the machines that matter, and set a labeled sample point on each one.

  2. Scheduled sampling

    Samples get pulled on the same schedule every month so the trend means something.

  3. Lab analysis

    Samples go to an independent lab for wear metals, contamination and oil condition.

  4. Report against OEM limits

    Results are checked against the manufacturer's alarm limits for that machine and written up verdict first.

  5. A call when something trends wrong

    If a reading is heading the wrong way, you hear about it by phone. You don't find it buried on page six.

Equipment covered

Crushing and screening equipment.

Every sample is tested against your OEM's recommended limits for that machine, not a generic chart.
