Configuration structure of hydrocyclone unit

Abstract

The invention discloses a hydrocyclone unit used in mine and metallurgy production, in particular to a configuration structure of a hydrocyclone unit used in a grinding system in Bayer alumina production. The structure is as follows: a feeding pipe of each hydrocyclone is connected with a main feeding pipe, an overflow pipe of each hydrocyclone is connected with a main overflow pipe, and an underflow pipe of each hydrocyclone is connected with an underflow trough. The configuration structure has a simple and reliable working principle, adopts the linear configuration of hydrocyclones, and prevents the problem of too large occupied area in the central feeding and the circular configuration of the hydrocyclones by increasing the configuration length. In the configuration method, only one feeding pipe, one overflow pipe and one underflow pipe are connected with the hydrocyclone unit, thereby greatly reducing the number of pipes in production, and facilitating the reduction of the labor intensity in production operation and repairing.

Description

technical field [0001] The invention relates to a hydrocyclone group used in mine and metallurgical production, in particular to a configuration structure of a hydrocyclone group used in a grinding system in Bayer process alumina production. Background technique [0002] Some of the original production systems of alumina plants use a closed-circuit graded grinding method to grind bauxite, that is, the bauxite is ground into raw ore pulp through a ball mill, and the raw ore pulp is pumped into a hydrocyclone for classification. The overflow of the hydrocyclone is sent to the next production section as qualified pulp, and the underflow of the hydrocyclone returns to the ball mill to continue grinding. Many small ball mills are used for grinding in the production, and each ball mill is equipped with a hydrocyclone, so the production capacity is low. [0003] In order to increase production capacity, some production processes adopt the "ball-rod two-stage grinding" production m...
