Pre-Operation Checks<\/strong><br \/>\nBefore starting a jaw crusher:<\/p>\n<ul>\n<li>Inspect all components (belts, jaws, bolts) for wear or looseness.<\/li>\n<li>Check lubrication levels (eccentric shaft bearings, toggle plate).<\/li>\n<li>Ensure no residual material is left in the crushing chamber.<\/li>\n<\/ul>\n<p><strong>2. No Load Startup<\/strong><br \/>\nThe crusher needs to start up when there is no loading, after running for a while, gradually increase the ore feeding. If the crusher makes an unusual sound, it should stop running and find out the reasons.<\/p>\n<p><strong>3. Feeding<\/strong><br \/>\nIt is essential to keep a steady status of material feeding and processing; the crusher chamber cannot be allowed to be filled with stone material. Meanwhile, prevent irrelevant objects such as a drill or a shovel from entering the crusher.<\/p>\n<p><strong>4. Blockage Prevention &amp; Clearing<\/strong><br \/>\nSometimes, a large rock plugs up the feeder mouth. In the event of a lock, rolling over the large stone makes the feeder mouth free at first. If blocking in the crusher chamber, it should stop feeding until the chamber is clear. For Your Attention, it is strictly that you use specialized tools to clear the obstruction instead of using your hand.<\/p>\n<p><strong>5. Lubrication<\/strong><br \/>\nL'huile de lubrification contribue au fonctionnement r\u00e9gulier et efficace de la machine. De plus, la temp\u00e9rature du palier excentrique ne peut pas d\u00e9passer 600 \u00b0c.<\/p>\n<p><strong>6. Maintenance and Repair<\/strong><br \/>\nCheck the wear of the discharge mouth regularly, and adjust the size of the discharge port in time according to the wear condition. Besides, replace the wear parts on time.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-4535 aligncenter\" src=\"https:\/\/www.jxscmachine.com\/wp-content\/uploads\/2019\/04\/wear-parts-of-crusher.png\" alt=\"pi\u00e8ces d&#039;usure du concasseur\" width=\"500\" height=\"381\" srcset=\"https:\/\/www.jxscmachine.com\/wp-content\/uploads\/2019\/04\/wear-parts-of-crusher.png 500w, https:\/\/www.jxscmachine.com\/wp-content\/uploads\/2019\/04\/wear-parts-of-crusher-300x229.png 300w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/p>\n<p>&nbsp;<\/p>\n<h2>Maintenance Schedule for Peak Performance<\/h2>\n<table border=\"1\" width=\"100%\">\n<thead>\n<tr>\n<th style=\"text-align: center;\"><strong>Maintenance Task<\/strong><\/th>\n<th style=\"text-align: center;\"><strong>Fr\u00e9quence<\/strong><\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"text-align: center;\">Lubricate bearings<\/td>\n<td style=\"text-align: center;\">Every 8\u201312 hours<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: center;\">Check jaw plate wear<\/td>\n<td style=\"text-align: center;\">Daily<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: center;\">Tighten bolts &amp; belts<\/td>\n<td style=\"text-align: center;\">Weekly<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: center;\">Inspect the toggle plate<\/td>\n<td style=\"text-align: center;\">Weekly<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: center;\">Replace worn parts (jaw liners, side plates)<\/td>\n<td style=\"text-align: center;\">As needed<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: center;\">Check alignment &amp; frame integrity<\/td>\n<td style=\"text-align: center;\">Monthly<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>Final Recommendations<\/h2>\n<ul>\n<li><strong>Invest in high-quality wear parts<\/strong> (manganese steel jaws, durable toggle plates).<\/li>\n<li><strong>Train operators on safe &amp; efficient practices<\/strong> to minimize downtime.<\/li>\n<li><strong>Follow a strict maintenance schedule<\/strong> to extend the crusher&#8217;s lifespan.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h2>Trusted Jaw Crushers &amp; Wear Parts from JXSC<\/h2>\n<p>Pour&nbsp;<strong>reliable <a href=\"https:\/\/www.jxscmachine.com\/fr\/categorie\/concasseur-de-roches\/\">mat\u00e9riel de broyage<\/a><\/strong>&nbsp;et&nbsp;<strong>durable wear parts<\/strong>, JXSC offers industry-leading solutions.
