The invention provides a multi-stage vibration screening
machine for ore fine selection, and belongs to the field of ore screening, the multi-stage vibration screening
machine comprises a screening frame, a multi-stage screening mechanism is arranged on one side of the screening frame and used for conducting multi-stage screening on ore, and a dust falling
assembly is arranged on one side of the multi-stage screening mechanism and used for conducting dust falling treatment on the ore being screened. A conveying
assembly is arranged on one side of the multi-stage screening mechanism and used for automatically conveying ore needing to be screened into the screening frame. According to the multi-stage ore screening device, by arranging the multi-stage screening mechanism, multi-stage screening of ore is achieved, and the effect of conveniently replacing a screen is achieved; through the arrangement of a
vibration motor and a spring, the screening frame can vibrate, and the first screen, the
second screen and the third screen are matched for use, so that multi-stage screening can be performed on ores; and the first screen, the
second screen and the third screen are connected to the screening frame in a bolted mode, so that a worker can replace the first screen, the
second screen and the third screen conveniently according to different ores, and the screening efficiency is improved.
