The recycling of lithium-ion batteries involves mechanical processing at different stages. After the feedstock has been shredded and dried, the crushed particles are sorted into fractions based on particle size and density. Our goal is to develop an optimized particle separation system supported by a digital inline sensor unit. By digitally monitoring the particle properties […]
