Problems solved by technology

At present, there are two conventional detection methods for grinding particle size: one is manual sampling and offline testing, and manual measurement in the laboratory; the other is using particle size detection equipment - particle size meter for online measurement. The reasons are: 1. The influence of human factors is large during manual operation, and the objectivity of the measurement results is poor; 2. The time interval of the measurement is long, and the time for the feedback of the measurement results is also long, so the obtained information la

Embodiment Construction

[0109] Taking the strong magnetic grinding and grading section of a large iron ore dressing plant as an example, the main iron ore of the dressing plant is pyrite and limonite, and the gangue is mainly barite, quartz, jasper and iron dolomite , the actual iron content of the ore is 33%. The strong magnetic separation system separates powder ore below 0-15mm, and adopts two stages of continuous grinding process. The lattice type ball mill forms a closed circuit with the hydrocyclone.

[0110] The schematic diagram of the two-stage grinding system is as follows: figure 1 As shown: the first-stage grinding product overflows from the classifier into the pump pool, and then is pumped into the cyclone by the rubber pump, and the grit part of the cyclone enters the second-stage ball mill for regrinding. Adding water flows into the pump pool by itself, forming a closed circuit. The cyclone overflow enters the subsequent sorting process.

[0111] The model of the ball mill is φ3200×...

Abstract

The invention is a soft measuring method for mineral grinding system flooding particle index, which is made up of hardware platform and measuring software, the method includes the selection of assistant variables, case representation, acquisition of initial case in case bank, case reasoning, case storing and maintaining steps. The method uses normal computer control system and normal detector to provide online process data, through a little artificial sampling, creates the soft measuring model of mineral grinding flooding particle based on case reasoning. Compared with normal particle meter, the method reduces the cost.

Description

technical field [0001] The invention belongs to the technical field of automatic measurement, and particularly relates to the measurement of the particle size index of the overflow of the hydrocyclone, the final product of the wet grinding system composed of a ball mill and a hydrocyclone, which is used to grind ore in the grinding section of a mineral processing plant. The method of soft measurement. Background technique [0002] In the mineral processing industry, a wet grinding system consisting of a ball mill and a hydrocyclone (referred to as a cyclone) is widely used to grind ore to the particle size range required by the mineral processing process. Too large or too small particles will affect the subsequent processing. Different operations will have adverse effects, so the cyclone overflow particle size (also known as grinding particle size, overflow particle size) is an important indicator to measure the operation quality of the grinding system. At present, there ar...
