Grading & packing
Coarse and fine fractions are selected to support packing, workability and controlled water demand.
Silica application consulting
Silica consulting for tile adhesive and dry-mix products
In dry-mix products, grading, moisture and mineral cleanliness affect water demand, workability, packing and consistency. A reliable raw-material specification helps formulation and plant teams avoid preventable variation.

Specification lens
What must be controlled
The target is not simply “high silica.” The useful specification is the combination of mineral, process and end-use behaviour that the customer actually needs.
Moisture
Dry aggregate and filler moisture must remain compatible with cement, polymers and storage life.
Cleanliness
Clay, salts, organics and oversize contamination are screened against formulation sensitivity.
Bulk handling
Bulk density, flow and segregation behaviour influence dosing accuracy and batch repeatability.
Process architecture
Indicative equipment train
Silica grading supports the formulation but does not replace full product testing against the applicable adhesive or dry-mix standard.
- 01
Mineral preparation
Dryer, crusher or mill as required by feed size and incoming moisture
- 02
Precision grading
Multi-deck screening or air classification for controlled aggregate and filler fractions
- 03
Storage
Dedicated silos or bins designed to limit moisture pickup and cross-contamination
- 04
Dosing & mixing
Weigh feeders, micro-dosing for additives and a suitable batch mixer
- 05
Finishing
Dust extraction, packing, batch identification and retained-sample system
Consulting approach
A decision path for tile adhesive and dry mix
Mineral selection, grading and quality guidance for silica fillers and aggregates used in tile adhesive, ready-mix plaster and dry-mix formulations.
Technical cautionSilica grading supports the formulation but does not replace full product testing against the applicable adhesive or dry-mix standard.
- 01
Define formulation duty
Tile adhesive, plaster and other dry mixes need different aggregate-to-filler behaviour.
- 02
Build candidate gradings
Compare source fractions and blends for packing, water demand, flow and segregation.
- 03
Validate plant handling
Confirm drying, screening, silo discharge, dosing and mixing repeatability.
- 04
Verify product performance
Connect mineral controls with workability, open time, slip, strength and field consistency.
Intended outcome
A fit-for-purpose silica specification that supports stable dry-mix production.
