The Versatile VAFS Grain Size Calculator computes the AFS Grain Fineness Number and full sieve distribution from retained weights – no manual arithmetic. Transmit to PC or print, with VSync web sync for cloud logging.
GRAIN SIZE CALCULATOR VAFS
Description
Grain Size Calculator VAFS
The Versatile VAFS Grain Size Calculator turns sieve-analysis data into the AFS Grain Fineness Number (GFN) and a full grain-distribution report in seconds. After a sample is shaken through a standard sieve stack, the operator enters or captures the weight retained on each sieve and the VAFS instantly computes GFN, percentage retention and distribution – eliminating manual multiplier arithmetic and calculation errors.
Why the AFS grain fineness number matters
The grain fineness number characterises the average grain size of foundry sand and directly governs permeability, casting surface finish and binder demand. Tracking GFN on every incoming sand lot and every reclaimed batch keeps moulding and core sand within specification.
Key features
- Automatic AFS Grain Fineness Number (GFN) calculation from retained weights
- Full sieve-distribution and percentage-retention report
- Transmit readings to a PC or take a printout
- VSync web sync: store and trend grain fineness across sand lots and view from any browser
Recommended companion equipment
Use with a Versatile Sieve Shaker and a standard AFS sieve set to generate the retained-weight data.
