Lattice type or overflow ball mill unit

Abstract

The invention discloses a lattice type or overflow ball mill unit and relates to a mineral separation unit, in particular to an apparatus used for mineral separation experiments in school and mine. The lattice type or overflow ball mill unit has the advantages that the structure is simple; the production cost is low; preliminary ore grinding, checking and classification, preliminary classification and sand return regrinding are carried out; open-circuit grinding function is realized; and operation is simple and convenient. The lattice type or overflow ball mill unit comprises a rack, a hopper, a discharging structure, a lattice type or overflow ball mill, a spiral feeder, a spiral classifier and a controller, wherein the discharging structure, the lattice type or overflow ball mill, the spiral feeder and the spiral classifier are provided with a separate motor for driving; the lattice type or overflow ball mill, the spiral feeder and the spiral classifier are mounted on the rack; the overflow ball mill and the spiral classifier are mounted in parallel; the spiral feeder is vertical to the lattice type or overflow ball mill and the spiral classifier; a feed port of the spiral feeder is located under a discharge port of the spiral classifier; and a discharge port of the spiral feeder is connected with a feed port of the lattice type or overflow ball mill. The lattice type or overflow ball mill unit is mainly used for mineral separation experiments in school and mine.

Description

technical field [0001] The invention relates to a beneficiation and grinding unit, in particular to a device for beneficiation tests in schools and mines. Background technique [0002] The grinding and sorting of the existing school teaching or mine beneficiation process are mostly completed by purchasing multiple single machines, including four machines including feeder, ball mill, screw classifier, and screw conveyor. The connection is not compact, it is not easy to implement automatic quantitative feeding, and it is not suitable for continuous open and closed circuit grinding experiments. Especially in the experiment, the water supply lines and circuits are inconvenient to operate and manage. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a grid-type, overflow-type ball mill unit with simple structure, low production cost, equal ore feeding, closed pre-grinding, inspection and grading, pre-grading, sand retu...
