Sep 10, 2015 Crushing, Screening And Blending Are Methods Used To Affect Aggregate Gradations. However, Even Following These Processes, The Material May Still Require Washing To Meet A Cleanliness Specification. Also, Screening Is Impractical For Aggregate Smaller Than No. 8 Mesh, In Which Case, Hydraulic Separation, Or Classifying, Becomes An Important Operation
Fine Aggregate Gradation Fineness Modulus FM should be between 2.3 and 3.1 FM is empirical determined by dividing the sum of percent retained on a standard series of sieves by 100 No. 4, 8, 16, 30, 50, 100 Coarser fine aggregate has a higher FM Sieve Percent Passing 38 in 100 No. 4 95-100 No. 8 80-100 No. 16 50-85
The screening process is where aggregates are sorted by grading. To be considered a fine aggregate, the material must pass through a 9-mm sieve. This ensures that the product can correctly serve its purpose and that all larger rock material is removed from the result.
Aggregate screens are commonly used within the rock and quarry industry for crushing and filtering of rocks. Just some of the many applications of WIRE CLOTH MANs aggregate screens include screening and separating stones, coal, mining, gravel, sand and other materials. Woven aggregate screen mesh is widely used in vibrating screen crushers.

Jun 20, 2016 Humidity has the greatest effect on the screening of fine material when the hole size is approx. 16 mm or smaller. The effect gets smaller with larger hole sizes. Due to the surface tension of water the finest particles adher to the surface of the larger particles and are carried to the wrong fractions.
