Micronised powder
High dispersibility and fine incorporation, with suitable dust and dosing controls.
How it is graded
From natural rock
to a defined fraction.
Grading controls particle format and handling. It does not erase the natural differences between deposits.

01 The process
Five stages shape the supplied grade.
Expand each stage to understand what it can control and what still depends on the natural source material.
01Extract & prepare
Natural zeolite-bearing rock is extracted, dried or conditioned and prepared for processing.
The deposit determines the mineral profile. Processing can control particle format, moisture and cleanliness, but it does not make different natural ores chemically identical.
02Crush or mill
Material is reduced to the particle range needed for powder or granular production.
Milling intensity shapes the balance between granules and fines. Micronised grades need different equipment and handling controls from crushed granular products.
03Screen by size
Screens separate the processed mineral into declared particle bands.
A grade such as 0.5–2 mm describes a target band, not the complete distribution. The retained oversize and fine fraction should be understood through particle-size data or sample inspection.
04Check & release
The agreed grade is checked against the available specification and supply documents.
Relevant checks may include particle-size distribution, moisture, mineralogy, chemistry, cation exchange capacity, bulk density and safety documentation, depending on the source and application.
05Pack & deliver
Packaging and logistics are matched to product, volume and delivery point.
Bag size, palletisation, full-load quantity, lead time and delivery access are confirmed as part of the commercial specification.
02 Particle formats
Size changes how a material behaves.
These bands describe portfolio formats, not universal recommendations. The application, equipment and full particle distribution decide the fit.
Fine grade
A fine granular or powder-rich fraction for formulation and close surface contact.
Screened granule
Controlled handling and blending across a range of commercial applications.
Coarse granule
Larger particles for robust handling, airflow, drainage or granular media evaluation.
Beyond the label
A grade name is only the start.
Two products labelled 0–2 mm can still differ in fines, moisture, density, mineralogy and handling.
Ask for the source-specific information that matters to your process, then validate a representative sample where appropriate.
