Embodiment 2

[0072] This embodiment provides a pulp concentration meter, which will be described in detail below.

[0073] 1. Applicable conditions

[0074] Any instrument has its own applicable conditions, and the same is true for this pulp concentration meter. Here we mainly talk about the applicable requirements for the measurement object (pulp). The specific conditions of the pulp are as follows:

[0075] (1) The pulp pressure is greater than or equal to 0.5Kg / cm 2 (gauge pressure); the minimum temperature of the slurry cannot be lower than the freezing point, and the maximum temperature is less than 100°C.

[0076] (2) The pulp must be Newtonian fluid. Must not be a non-Newtonian fluid, such as a Bingham fluid. Usually, the concentration of transported pulp is controlled (when the concentration is too high, water should be replenished appropriately) so that its mass concentration is less than 70% to 60% to meet the requirements. The greater the ore density, the higher the mass conc...

Abstract

The invention discloses a conductive online pulp concentration measurement method, belonging to the technical field of pulp concentration / density measurement, comprising at least two insulating connecting pipes and at least three electrode pipes, the insulating connecting pipes and the electrode pipes are arranged at intervals, the The insulating connecting pipe is arranged between two adjacent electrode tubes, and the two adjacent electrode tubes are respectively connected to both ends of the insulating connecting pipe. The electrode tube includes a liquid-contacting ring section. When measuring In the entire electrode tube, only the liquid-contacting ring section is in contact with the slurry. The invention applies the conductivity online pulp concentration meter to the pulp concentration measurement work, which can more conveniently carry out online measurement of the pulp concentration, thereby avoiding the situation of poor connection between process sections or waste of transport power, and satisfying the requirements of the mine on-line Concentration / density meter usage requirements.

Description

technical field [0001] The invention relates to the technical field of pulp concentration / density measurement, in particular to a conductive online pulp concentration measurement method. Background technique [0002] Most metallurgical mines use wet grinding process to sort the mined ores, and most of them use multi-pass grinding process. Pipeline pumping is used to transport the pulp between the upstream and downstream grinding processes. [0003] Due to the natural fluctuations in the grade of the original ore, there is also a natural fluctuation in the proportion of tailings (waste ore) that is removed during ore grade selection. In fact, the speed of ore input into the mill and sorter has been lack of precise control, so the concentration of the slurry transported between each process section has great fluctuations, resulting in poor connection between process sections or waste of transport power Case. Because of this, mines have always had a realistic demand for onli...
