In the fabrication of dry battery electrodes—where active materials, conductive agents, and PTFE binders are "fibrillated" without the use of NMP solvent. 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.

A 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.

Part Number	ESMDBER2RHRPGAS (ESM-DBE-R2RHRPGAS)
Power	AC220V±10%, single phase, 50/60Hz, 6000 W
Hot Rollers	Φ150×220mm mm (effective hot rolling width: 200 mm) Roller is made of DC53 stainless steel Heating temperature on three rollers: Max:150℃ (independently controlled). The recommended temperature for three rollers can be 80°C, 80°C, and 60°C.
Calendering Speed	0.05- 1 m/min (the rolling speed of each roller can be adjusted independently) Normally the recommended gradient speed: 0.1 m/min (roller 1), 0.12 m/min (roller 2); 0.15 m/min (roller 3). The slight speed difference is beneficial to high quality film formation without any damages.
Calendering Gap/Pressure	0-1.2 mm (digital set and adjustable) The 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) Max. 15 T (pressure adjustable) 0.1-0.5 T for roller 1 and 2; while 0.2-2 T for roller 2 and 3 (depends on active material types)
Powder Feeding Hopper	A powder feeding hopper is design at the top of rolling press, which is convenient for powder feeding to form electrode sheet.
Note	Dry electrode fabrication processes: (1) Powder Mixing (ESLDBEHSDM) The 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℃). A high-speed mixing was conducted in a short time to generate partially PTFE fibrillation. The large agglomerates were removed with a 30 mesh filter. (2) Sheet Formation/Rolling Press Place the powder mixture into the feeding hopper. The three rollers with gradient gap/pressure will from the self-standing dry film. A cutter is designed to cut the film edge. (3) Electrode Lamination (combined with another roll-to-roll laminator) The thin self-standing dry film can be further laminated (same speed) with carbon-coated foil (eg: CBACCCCFR, CBCCCCAFR) to form the complete dry battery electrode.
