Lloyds Grinding Gauge is designed to meet today's QC standard requirement. It combines an intelligent selection of special steel construction for quick and efficient measurement of biggest particle size in any dispersion. The term 'fineness of grind' is defined as the reading obtained on a gauge under specified conditions of test and the reading indicates the depth of the gauge at which discrete solid particles are readily discernible. The term “Hegman” is sometimes applied as a generic description to these gauges and, in spite of National and International specifications recommending the adoption of the micron (um) scale, arbitrary scales such as Hegman, North, FSPT. etc., are sometimes wanted. Each gauge consists of a block of hardened stainless steel supplied with a scraper blade.
Special grade hardened steel
Long-term durability and reliability
High accuracy precision machining
ASTM D 1210
BS 3900 (Part C6)
How to use: The test consists of placing a small volume of product on the deep end and drawing it with a straight scraper toward the shallow end. The position on the scale where oversize particles and their tracks appear can be rated for determination of dispersion.
