crushing of quartz sand to produce silt particles

Sand itself sits between gravel and silt with its grains being smaller than those that make up gravel but larger than those that make up silt. As a general rule, sand is classified as such if its particles range from 2mm at largest down to 0.06mm at their smallest

micromechanics of quartz sand breakagein a fractal

Apr 15, 2014 · The sand-to-silt size reduction pathway in quartz possesses fractal properties (in sorting, maximum particle size, fractal dimension, and modal size distribution). Light transmission microscopy examination of sand- and silt-sized quartz samples before crushing revealed evidence of surface imperfections and internal planes of varied taxonomy

Traditional views have attributed the formation of loess-sized quartz silt particles to glacial processes. Glacial grinding was considered to be the only mechanism capable of producing loessic silt in the quantities necessary for the formation of loess deposits. This idea has been strengthened by the apparent close association between present or former glacierised regions and major global
