Shock loads from dropping 500 kg+ boulders are extreme.<\/p>\n<p><strong>&#9656; Crusher discharge conveyor:<\/strong> Chain drives carry crushed material from the crusher to screens or stockpile. Abrasive dust concentration is highest at this point.<\/p>\n<p><strong>&#9656; Vibrating screen drive:<\/strong> Some screens use chain-and-sprocket exciter drives. The cyclical vibration accelerates fatigue on sprocket teeth and keyways.<\/p>\n<p><strong>&#9656; Recirculation\/oversize return:<\/strong> Oversize material rejected by screens is conveyed back to the crusher via a chain-driven recirculation conveyor.<\/p>\n<p><strong>&#9656; Wash plant conveyor:<\/strong> For washed aggregates, sprockets must resist both abrasion and moisture\/chemical corrosion.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/sprockets.top\/wp-content\/uploads\/2026\/03\/sprockets-4.webp\" alt=\"Heavy-duty sprocket range for crusher applications\" style=\"max-width:100%;height:auto;border-radius:6px; margin:15px 0;\" loading=\"lazy\" \/><\/p>\n<h2 style=\"border-top:4px solid #37474F;border-bottom:1px solid #37474F;padding:10px 0;color:#37474F;font-size:clamp(20px,3vw+8px,28px);margin:35px 0 18px 0;\">Compatibilit\u00e0<\/h2>\n<div style=\"overflow-x:auto;\">\n<table style=\"width:100%;border-collapse:collapse;font-size:clamp(12px,1.8vw+8px,15px);\">\n<tr style=\"background:#37474F;color:#fff;\">\n<th style=\"padding:8px;border:1px solid #ddd;\">Crusher Position<\/th>\n<th style=\"padding:8px;border:1px solid #ddd;\">Tipi di catena<\/th>\n<th style=\"padding:8px;border:1px solid #ddd;\">Attrezzatura*<\/th>\n<\/tr>\n<tr>\n<td style=\"padding:8px;border:1px solid #ddd;\">Primary Feeder<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">ANSI 160\u2013240, Collegamento falsificato<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">Metso, FLSmidth, Sandvik<\/td>\n<\/tr>\n<tr style=\"background:#ECEFF1;\">\n<td style=\"padding:8px;border:1px solid #ddd;\">Discharge Conveyor<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">ANSI 100&#8211;160 Duplex\/Triplex<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">Terex, McCloskey, Powerscreen<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:8px;border:1px solid #ddd;\">Screen Drive<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">ANSI 80\u2013120<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">Haver &amp; Boecker, Schenck, IFE<\/td>\n<\/tr>\n<tr style=\"background:#ECEFF1;\">\n<td style=\"padding:8px;border:1px solid #ddd;\">Wash Plant<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">ANSI 80&#8211;120 galvanised<\/td>\n<td style=\"padding:8px;border:1px solid #ddd;\">CDE, McLanahan, Weir<\/td>\n<\/tr>\n<\/table>\n<\/div>\n<p style=\"font-size:clamp(11px,1.5vw+6px,13px);color:#666;\">*I nomi dei marchi sono utilizzati solo a scopo di riferimento.
