Therefore, the separation curves describing the characteristics of separation in terms of air velocity become important when processing solid waste particles in vertical air classification. In vertical air classification, a mixture of lighter and heavier particles is fed into a vertical upward airflow as illustrated in Fig. 1. The particles ...Web

De Wilde and de Broqueville [78] carried out gas–solid separation by using a vortex reactor for two different types of particles, polymer particles, and salt particles. The solid accumulation in the vicinity of the gas inlet slots led to the non-uniform distribution of the gas flow, which caused "slugging" until complete separation of ...Web
