Fragility is not determined by particle size or bulk density alone. It depends on particle structure, fracture strength, shape, moisture content, surface characteristics, and sensitivity to impact and abrasion.<\/span><\/p>\n<p><span style=\"font-family: Battambang, sans-serif;\">Different industries illustrate these challenges particularly well.<\/span><\/p>\n<div>\n<ul>\n<li><span style=\"font-family: Battambang, sans-serif;\"><b>Food industry:<\/b> Breakfast cereal pieces, puffed rice, extruded snacks, dried fruit pieces, roasted coffee beans, spray-dried milk powder, and delicate food granules can experience breakage, fines generation, or changes in appearance during conveying.<\/span><\/li>\n<li><span style=\"font-family: Battambang, sans-serif;\"><b>Polymer industry:<\/b> Polypropylene and polyethylene pellets, expanded polystyrene beads, engineering polymer granules, and specialty resin pellets may suffer chipping, dust generation, angel hair formation, abrasion, deformation, or contamination.<\/span><\/li>\n<li><span style=\"font-family: Battambang, sans-serif;\"><b>Chemical industry:<\/b> Porous catalyst particles, silica gel granules, molecular sieve beads, fertilizer granules, and specialty chemical crystals may degrade through impact, attrition, or abrasion.<\/span><\/li>\n<li><span style=\"font-family: Battambang, sans-serif;\"><b>Petrochemical industry: <\/b>Polyethylene and polypropylene resin pellets, polymer additives, catalyst powders, and certain porous catalyst carriers require careful handling to maintain particle integrity and minimize fines.<\/span><\/li>\n<li><span style=\"font-family: Battambang, sans-serif;\"><b>Mineral industry:<\/b> Lightweight expanded clay granules, porous mineral pellets, certain zeolite products, specialty ceramic granules, and friable mineral particles may fracture during transportation.<\/span><\/li>\n<\/ul>\n<div><span style=\"font-family: Battambang, sans-serif;\">Not every material in these categories is equally fragile.
