  • 100mm Width Electric Calender Roller Press Machine for Lithium Battery Electrode Rolling

Model: MR-DG100L

MR-DG100L Lab Roll Press Machine is a compact precision electric rolling press machine. It has dual rollers of 96 mm dia. x 100mm width and dual grade micrometer. This lab roll press machine is an ideal rolling press for adjusting thickness and increasing active material density of the electrode in Li-Ion batteries research after coating and drying.

Features：

1. Hard chrome plated on surface. Material HRC62.
2. Transparent protective plate is designed for safety operation.
3. Press gap is adjustable.
4. Rolling speed and press thickness is adjustable .

Application NotesThis roller is specially designed for battery R&D in terms of its advantages as affordable, compact and precise.
1. Must use acetone to clean and dry rollers’ surfaces after each use to avoid rusting.
2. Coated Rust-proof oil if machine were to be unused for a long period time
3. The minimum thickness of the rolled sheet should depend on the physical property of the materials.
