The invention discloses a belt type roller
magnetic separator. The belt type roller
magnetic separator comprises a redirecting roller, a left
machine frame, a conveying belt, a rain spraying gradient
slurry dispersing
sieve, a belt conveying bracket, a conveying belt lower carrier roller, an upper flusher, an electric roller and a right bracket and is characterized in that: a plurality of groove-shaped high-strength
magnet carrier roller devices are arranged below the conveying belt on the upper layer. The high-strength
magnet carrier roller devices can magnetize patterned belts completely above the devices, and
iron powder in the
slurry is sucked by the magnetized patterned belts and falls into pits of the patterned belts. After the patterned belts upstream enters a non-magnetic region, all the iron concentrate
powder falls into an iron concentrate
powder bank and are collected, so that the
magnetic separation efficiency is greatly improved. The belt type roller
magnetic separator has the advantages of large conveying quantity, high collecting capacity, capacity of reducing washing of
slurry on the adsorbed
iron powder, high
magnetic separation efficiency, high yield, high
iron powder adsorption capacity,
resource saving, simple structure and easiness in
assembly, and is ideal equipment for extracting iron concentrate
powder through
iron ore magnetic separation and
tailings treatment.
