{"product_id":"efssjmrbm","title":"ECS-FS Single Jar Mini Rolling Ball Mill (1800 rpm, 100 mL), EFSSJMRBM","description":"\u003cp\u003eA single jar mini rolling ball mill (often called a drum mill or jar mill) operates on a completely different principle than the high-energy vibratory or planetary mills we've discussed. It is a low-energy, long-duration milling solution. Instead of high-frequency vibration, it relies on the gravity-driven cascading motion of grinding media inside a rotating horizontal jar.\u003c\/p\u003e\n\u003cp\u003eIn a rolling ball mill, the jar is placed on two or more motorized rollers. As the rollers turn, the jar rotates, and the grinding balls are lifted by centrifugal force and friction until they reach a certain height, after which they \"cascade\" or fall back down onto the sample. (1) \u003cstrong\u003eImpact\u003c\/strong\u003e: Occurs at the \"toe\" of the charge where balls fall. (2) \u003cstrong\u003eAttrition\/Shear\u003c\/strong\u003e: Occurs between the sliding balls and the jar wall. (3) \u003cstrong\u003eCritical Speed (nc)\u003c\/strong\u003e: This is the most vital parameter. If the jar rotates too slowly, the balls just slide (no grinding). If it rotates too fast, centrifugal force pins the balls to the wall (no grinding). The ideal operating speed is typically 65% to 80% of the critical speed.\u003c\/p\u003e\n\u003ctable style=\"height: 535.4px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 47.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eEFSSJMRBM (EFS-SJMRBM)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 47.6px;\"\u003e\u003cem\u003ePower\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eAC110 or 220V±10%, single phase, 50\/60Hz, 60 W \u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 106.4px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 106.4px;\"\u003e\u003cem\u003eMilling Features\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 106.4px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eMilling\/mixing with friction\u003c\/li\u003e\n\u003cli\u003eBoth dry\/wet milling can be operated\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eRubber roller rotation speed: \u003cspan style=\"color: rgb(255, 42, 0);\"\u003eMax. 1800 rpm\u003c\/span\u003e (adjustable).\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eThe \u003cspan style=\"color: rgb(255, 42, 0);\"\u003etwo rollers\u003c\/span\u003e were covered with PU coating. \u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 104.2px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 104.2px;\"\u003e\u003cem\u003eMilling Jar Features\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 104.2px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eJar Volume: Max. 100 mL (single jar).
