100 x 200 mm Laboratory Heated Roller Press Battery Electrode Sheet Calendering Machine

Product Overview

This heated roller press is engineered for small-scale lithium battery electrode calendering, combining controlled roll heating, high-hardness roll surfaces, and mechanically adjustable compression in one compact laboratory system. A geared motor drives the precision rolls while the adjustable nip applies forming pressure to improve electrode compactness and density. The equipment supports practical, repeatable sheet reduction without the footprint or complexity of production-scale calendering equipment.

Designed for university laboratories and enterprise trial lines using single-phase 220 V power, this unit serves battery-material development, electrode process optimization, and small-batch manual rolling. It is also suitable for laboratory rolling of limited quantities of gold, silver, copper, aluminum, and other non-ferrous materials where controlled thickness reduction is required. Its 200 mm maximum working width supports representative electrode samples and research-scale process trials.

The equipment is built around hardened precision rolls with a surface hardness of HRC62, a 5 mm surface hardening depth, and roll cylindricity of <= +/-2 um. Independently controlled roll temperatures, a continuously adjustable 0-3 mm effective gap, and stepless speed control give researchers direct control over the thermal-mechanical conditions that affect sheet formation. This robust configuration is intended for dependable daily operation in demanding battery and materials research environments.

Key Features

• Independent Dual-Roll Heating: Each roll temperature can be controlled independently and adjusted as required, with a roll temperature of approximately 130 degrees C. This allows operators to set thermal conditions appropriate to laboratory electrode rolling and heat-assisted material processing.

• Precision Gap Adjustment: The effective roll gap is continuously adjustable from 0-3 mm through a mechanical adjustment mechanism. Researchers can set the compression opening for electrode sheets and laboratory material samples while maintaining a simple, direct operating method.

• High-Hardness Calender Rolls: The rolls provide HRC62 surface hardness and a 5 mm hardened surface depth. This construction supports resistance to wear during repeated rolling operations and helps preserve the working surface under laboratory use.

• Controlled Roll Geometry: Roll cylindricity is specified at <= +/-2 um. Accurate cylindrical form helps distribute compression consistently across the working width, supporting uniform sheet processing and more reliable comparative experiments.

• Variable Linear Speed: Stepless speed adjustment provides a linear speed range of 0-4.0 m/min. Operators can select a feed rate suited to the sample, process stage, and required rolling conditions rather than relying on a single fixed speed.

• Substantial Compression Capability: With a maximum pressure of 3 T, the system provides the pressing force required to form and densify laboratory electrode sheets. The mechanical roll drive applies pressure as material passes through the adjustable nip.

• 200 mm Working Width: The maximum working width is 200 mm, matched to the 100 mm diameter by 200 mm roll dimensions. This format is well suited to research electrode sheets and small-scale material rolling where manageable sample sizes are needed.

• Laboratory-Oriented Electrical Configuration: The equipment operates from 220 V power with a 2.4 KW rating. Its compact 550 x 320 x 850 mm overall dimensions support placement in university and enterprise laboratory trial-line environments.

Applications

Technical Specifications

The specification set is focused on the parameters that govern laboratory rolling performance: roll size, working width, surface hardness, roll geometry, effective gap, pressure, temperature, and linear speed. The 100 mm diameter by 200 mm roll format is paired with a maximum 200 mm working width, allowing the full roll face to be used for suitably sized samples. For teams comparing electrode formulations or coating conditions, this working format supports meaningful sample evaluation without requiring production-scale equipment.

Temperature management is particularly important when assessing heat-assisted electrode processing. The two roll temperatures can be controlled independently and adjusted, giving the operator the ability to establish the rolling condition required for the experiment. The stated roll temperature is approximately 130 degrees C. Combined with the adjustable 0-3 mm effective gap and the maximum 3 T pressure, this provides a defined set of thermal and mechanical controls for laboratory sheet compression.

Speed is equally relevant to process consistency. Stepless variable speed with an adjustable 0-4.0 m/min linear-speed range lets users control how material passes through the rolls. A suitable speed can be selected for the sample and research objective, then retained as part of a documented experimental condition. This is useful where researchers need to compare sheet density, thickness reduction, or forming response between sample batches.

The roll construction supports the mechanical demands of repeated laboratory calendering. HRC62 surface hardness, 5 mm roll surface hardening depth, and cylindricity of <= +/-2 um provide concrete indicators of the equipment's rolling architecture. These attributes are relevant to buyers who require a durable work surface and controlled roll form for recurring battery-material and non-ferrous-material processing.

Why Choose This Product

• Built for repeatable laboratory calendering: The combination of independently adjustable roll heating, mechanical gap adjustment, 3 T maximum pressure, and stepless speed control gives users practical command over core rolling variables.

• Precision-focused roll construction: HRC62 roll surface hardness, 5 mm hardening depth, and <= +/-2 um cylindricity demonstrate an engineering focus on durable surfaces and controlled sheet contact.

• Relevant scale for R&D and trials: A 200 mm maximum working width and single-phase 220 V electrical configuration make this unit suitable for university laboratories and enterprise experimental lines.

• Versatile material capability: Beyond lithium battery electrode sheets, the equipment is intended for laboratory rolling of small quantities of gold, silver, copper, aluminum, and other non-ferrous materials.

• Premium process control investment: Adjustable temperature, gap, and linear speed enable teams to establish consistent rolling conditions for demanding materials research rather than treating calendering as a fixed, uncontrolled step.
