Simple measuring method for content of micro-fine-particle-level particles

Abstract

The invention discloses a simple measuring method for the content of micro-fine-particle-level particles. The simple measuring method includes the following steps that 1, a simple liquid separating device is manufactured through a beaker, a test tube stand, a flexible rubber hose and a clamp in a laboratory; 2, settling time required when different particles settle by a fixed height is determined; 3, when the settling time is up, liquid above a settling starting point of the fixed height is pumped out through a siphon; the process is carried out at least twice till the settling range is a fresh water layer, then the collected liquid is filtered, dried and weighed, and the content of the micro-fine-particle-level particles in tailings is calculated. According to the simple measuring method, measuring and calculation are carried out through the common tools in the laboratory, the simple measuring method is simple and easy to operate, inconvenience caused when measuring is carried out through a laser particle size analyzer is avoided, and therefore a department without a special instrument can measure the content of the micro-fine-particle-level particles and learn production conditions in time.

Description

Technical field [0001] The invention belongs to the field of determining the particle size composition of metallurgical mine tailings, and particularly relates to a simple method for determining the content of fine-grained particles. Background technique [0002] The particle size analysis is generally carried out with a set of sieve, but the minimum size of the set of sieve is 400 mesh, that is, the sieve opening is 38μm. For the measurement of finer particles, such as -10μm, -24μm, you need to measure with instruments. . [0003] In the determination of fine particle level content, laser particle size analyzers are often used, but some units do not have laser particle size analyzers. Therefore, the measurement of fine particle level content is generally entrusted to research units for determination, but the measurement cycle is long and it is not possible to know the tailings in time. The particle size distribution, especially the fine particle size, includes the content determi...

[0003] In the determination of fine particle size content, laser particle size analyzers are often used, but some units do not have laser particle size analyzers, so the measurement of fine particle size content is generally entrusted to research units for determination, but the measurement cycle is long, and it is impossible to know in time what is in the tailings. The particle size distribution of the particles, especially the fine particle size, including the content determination of -10μm
