The invention discloses a comprehensive recycling process of second
zinc oxide rotary kiln tailings and a
production line of the comprehensive recycling proces. The process comprises the following steps of screening, crushing, dry
magnetic separation, ball milling,
magnetic separation, reselection, ball milling,
magnetic separation, reselection,
dehydration, reduction, screening and packaging. The
production line of the comprehensive recycling process of the second
zinc oxide rotary kiln tailings comprises a
discharge bin, a vibrating screen, a vertical hammer
crusher, a magnetic separation belt, a first single-bin
ball mill, a first wet type half counter-current
magnetic separator, a first
precipitation type classifier, a second single-bin
ball mill, a second wet type half counter-current
magnetic separator, a second
precipitation type classifier, a vibrating dehydrator, a
drying kiln, a rotary type
hydrogen reducing furnace, a three-dimensional vibrating screen and another
discharge bin, wherein the
discharge bin, the vibrating screen, the vertical hammer
crusher, the magnetic separation belt, the first single-bin
ball mill, the first wet type half counter-current
magnetic separator, the first
precipitation type classifier, the second single-bin ball mill, the second wet type half counter-current magnetic separator, the second precipitation type classifier, the vibrating dehydrator, the
drying kiln, the rotary type
hydrogen reducing furnace, the three-dimensional vibrating screen and the other discharge bin are arranged in sequence. The comprehensive recycling process and the
production line of the comprehensive recycling process have the advantages of
energy conservation and emission reduction, resource recycling is realized,
energy consumption and manpower are effectively reduced, and the product quality is increased.
