Pyford Brook Quarry Density Monitoring Review
An application review for possible density monitoring in cyclone and mineral-washing circuits at Pyford Brook Quarry.
Sand and gravel density monitoring at Pyford Brook in Staffordshire
Pyford Brook Quarry near Alrewas, Staffordshire uses primary and secondary cyclones, Hydrosizers, dewatering screens and effluent handling to produce graded sand and gravel. The SDM ECO can add continuous non-nuclear density data on an appropriate cyclone feed, helping operators monitor solids loading alongside classification and lignite-removal variables. PMA would validate the signal against representative process samples.
Application note: This guide uses published process information to identify where SDM ECO measurement may be useful. PMA would confirm the current process, pipe conditions and calibration range before recommending an installation.

Quarry process and SDM ECO opportunities
The public flowsheet supports a precise review of individual pumped streams.
Local process and material
The published plant processes Trent Valley sand and gravel containing lignite through staged washing, gravity separation, cyclones and dewatering.
Where SDM ECO can help
Primary or secondary cyclone feed may be considered where density adds information about feed loading and remains representative across operating states.
What to confirm
Confirm cyclone feed pipework, pressure, flow, density range, lignite and fines variation, water additions and the current process-quality measurements.
Application considerations
Density cannot distinguish lignite from mineral solids or replace grading and product-quality analysis. Composition changes may alter interpretation.
A practical SDM ECO review pathway
These four steps show how PMA would assess a potential SDM ECO duty, from selecting the process stream through to validating the measurement against representative site data.
1. Select one stage
Choose primary or secondary cyclone duty.
2. Define composition
Document mineral, lignite and fines variability.
3. Align instruments
Time-match density, pressure, flow and samples.
4. Confirm limits
Document when composition makes the trend invalid.
Where continuous density may add value
Used with pressure and flow, a density trend may help operators understand cyclone loading, water balance and changes in staged classification.
What PMA would verify on site
PMA would map each stream, confirm full-pipe conditions and select a comparison method that captures both bulk solids loading and material composition.
Sources and application guidance
Public facts used for this site profile are linked below. Process descriptions can change, so PMA would confirm the current flowsheet, operating range and measurement objective directly with the operator before proposing hardware.
