Qingdao, China – AKW has achieved remarkable progress in carbon powder fibrosis testing using its intensive mixer granulator. In lab validation experiments, the machine completed the whole carbon powder fibrosis, dispersion and granulation process within only 3 minutes, greatly shortening material development cycles for dry electrode and carbon composite powder industries.

Carbon powder fibrosis is a critical procedure for lithium battery dry electrode manufacturing, carbon paste, conductive carbon composite and carbon material R&D. Traditional mixing equipment normally requires long mixing time, and often suffers from poor binder fibrillation, powder agglomeration and inconsistent particle quality. The intensive mixer granulator adopts dual-motion countercurrent mixing principle, combining high-speed rotor shear and vessel rotation. It delivers strong, uniform shear force to realize binder fibrosis while evenly dispersing carbon powder, and completes granulation in one chamber without material transfer between multiple devices.

During this test, technicians adopted standard carbon powder formula to verify fibrosis effect. After 3 minutes of continuous operation, the sample showed uniform fiber network structure, good particle sphericity and low segregation. The one-step process eliminates repeated feeding and transfer steps, reduces contamination risk and improves batch repeatability.

Quote from AKW Material Process Engineer： “For dry electrode R&D, controlled fibrosis is always a tough bottleneck. Our intensive mixer granulator balances shear intensity and mixing time perfectly. Finishing carbon powder fibrosis in 3 minutes helps battery material researchers speed up formula screening and pilot testing. We can provide lab machine trial test for global customers.”

This mixing & granulating equipment is widely applied in conductive carbon powder, dry electrode materials, carbon black, graphite, refractory, UHPC and welding powder. AKW supplies lab scale, pilot and full production models, and accepts custom formulation tests for overseas material manufacturers.

Companies working on dry electrode and carbon composite materials are welcome to send samples for lab fibrosis test.
