CRUSHER OF MINERAL POWDER-LIKE MATERIALS Russian patent published in 1996 - IPC

FIELD: manufacture of building materials. SUBSTANCE: device is based on the fact that during fast passing over point of polymorphic transition in mineral particles the thermostresses resulting in crack appearance arise. Flow-type electric-heating furnace is used in the device for heating. Thermosiphon is used for cooling. Thermosiphon shape represents combination of surfaces of two bodies of revolution having one common axis. Its upper condensation and lower evaporative parts are made as cones whose vertex is directed downwards. Flow-type furnace is mounted in space restricted by its middle part. EFFECT: enhanced efficiency, reduced power consumption and service expenditure. 2 cl, 1 dwg
