WORN-OUT TIRE CRUSHING DEVICE Russian patent published in 2000 - IPC

FIELD: recovery of worn-out tires. SUBSTANCE: device has current pulse generator and cryostat filled with cryogenic liquid which accommodates perforated magazine that follows tire surface and incorporates set of needle electrodes and internal electrode. The latter is connected to perforated magazine and each of needle electrodes is electrically insulated and connected to pulse generator through coaxial cable whose length is found from equation L ≥ 0,5(t_v+Δt_v)•V_c, where t_v is maximum time of tire rupture, s; Δt_v is maximum time interval between voltage application and initial rupture of tire, s; V_c is speed of voltage wave propagation through cable, m/s. EFFECT: improved efficiency of tire rupture at reduced power requirement. 2 dwg
