Abstract

The crushing effect of waste phone's circuit boards by mechanical–physical method under different pretreatment processes (without pretreatment, disassembling electrical components, heating treatment) was investigated. The composition, mass distribution, feature, liberation degree of crushed products were analyzed. The results show that the heating process has the obvious influence on the mass distribution and disassembling has almost no effect on the crushing effect. The liberation is easiest for the circuit boards after heating and is difficult for the circuit boards after disassembling. Considering the impact of environment and investment, the waste phone’s circuit boards can be directly crushed without disassembling and heating treatment.
