Magnetic dry lean iron ore separating machine

Abstract

The magnetic dry lean iron ore separating machine has one double-layered frame. The lower layer of horizontal frame has one magnetic wheel set on one end, one driven wheel on the other end, one belt conveyer between the magnetic wheel and the driven wheel and one feeding bin over the driven wheel. The upper layer triangular frame has one driving wheel on one end, one magnetic wheel on the other end, one driven wheel in the upper part, one belt conveyer with tightening wheel to connect the driving wheel, the magnetic wheel and the driven wheel, and permanent magnets to form suspending magnetic field inside the conveying belt between the driving wheel and the magnetic wheel. The present invention has combined magnetic field structure, increased contact area between the material and the magnetic field, raised magnetic field utilization rate, and excellent separating effect, and is especially suitable for magnetic separation of lean iron ore.

Description

Technical field: [0001] The invention relates to a magnetic dry separator, in particular to a magnetic dry separator for lean iron ore. Background technique: [0002] The known permanent magnet dry separator generally has a cylindrical structure, which is composed of a feeding box, a drum placed in the feeding box and rotating with the main shaft, and an arc-shaped permanent magnet system installed inside the drum that does not rotate with the drum. It has the following defects in the process of use: first, the gap between the roller and the baffle plate in the feeding box is too small, and the raw material throughput is low, which affects the sorting efficiency; second, the contact area of ​​the magnetic field formed by the raw material and the arc-shaped permanent magnet system Small, low magnetic field utilization rate, resulting in unclear separation of iron ore and wool, high iron content in wool, especially not suitable for separation of lean iron ore. Invention cont...
