The Roll-to-Roll (R2R) Hot Rolling Press is the equipment that bridges the gap between raw powder and a functional, commercial-grade electrode. The hot rolling in a dry process serves as the primary film-forming and lamination engine.\u003c\/p\u003e\n\u003cp\u003eA complete R2R dry processing line typically utilizes the hot rolling press in two distinct stages: (1) The fibrillated \"battery dough\" from your high-speed dry mixer is fed into the heated nip of the press. (2) In the second pass, the free-standing film is paired with a current collector (aluminum or copper foil) that has been pre-coated with a thin conductive primer.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"height: 201.2px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 35.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eESMDBER2RHRPGAS (ESM-DBE-R2RHRPGAS)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003ePower\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003eAC220V±10%, single phase, 50\/60Hz, 6000 W \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003eHot Rollers\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003eΦ150×220mm mm (effective hot rolling width: \u003cspan style=\"color: rgb(255, 42, 0);\"\u003e200 mm\u003c\/span\u003e)\u003c\/li\u003e\n\u003cli\u003eRoller is made of DC53 stainless steel\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eHeating temperature on three rollers: Max:150℃ (independently controlled). \u003c\/li\u003e\n\u003cli\u003eThe recommended temperature for three rollers can be 80°C, 80°C, and 60°C.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e          \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/ESMDBER2RHRPGAS_02_100x100.png?v=1775922433\" alt=\"\" style=\"float: none;\"\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003eCalendering Speed\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003e0.05- 1 m\/min (the rolling speed of each roller can be adjusted independently)\u003c\/li\u003e\n\u003cli\u003eNormally the recommended gradient speed: 0.1 m\/min (roller 1), 0.12 m\/min (roller 2); 0.15 m\/min (roller 3). \u003c\/li\u003e\n\u003cli\u003eThe slight speed difference is beneficial to high quality film formation without any damages.  \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003eCalendering Gap\/Pressure\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003e0-1.2 mm (digital set and adjustable)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eThe recommended gap for roller 1 and 2 is 0.1 mm, while that for roller 2 and 3 is 0.18 mm (stainless steel foil is go through it)\u003c\/li\u003e\n\u003cli\u003eMax. 15 T (pressure adjustable)\u003c\/li\u003e\n\u003cli\u003e0.1-0.5 T for roller 1 and 2; while 0.2-2 T for roller 2 and 3 (depends on active material types) \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003ePowder Feeding Hopper\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003eA powder feeding hopper is design at the top of rolling press, which is convenient for powder feeding to form electrode sheet. \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e          \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/ESMDBER2RHRPGAS_03_100x100.png?v=1775923276\" alt=\"\" style=\"float: none;\"\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003eNote\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\n\u003cp\u003e \u003cstrong\u003eDry electrode fabrication processes: \u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli style=\"font-weight: bold;\"\u003e\u003cstrong\u003e(1) Powder Mixing (\u003ca href=\"https:\/\/echemsupplies.com\/products\/esldbehsdm?variant=47529517187302\"\u003eESLDBEHSDM\u003c\/a\u003e)\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe active material (eg: graphite, LFP, NMC) is mixed with conductive carbon at medium level speed, and then add the PTFE into the mixture and mix it at a low speed (Temperature=10-15℃).
