Problems solved by technology

The disadvantage of this measurement method is that the process of wet sieving and pouring the sieved material back into the concentration pot is easy to spill the material and affect the accuracy. If the solid content is high, the wet sieving process is time-consuming and laborious.
[0005] The main method for measuring the density of mineral materials is the pycnometer method. This method has the characteristics of accurate measurement and high precision. The disadvantage is that the operation is complicated and the measurement time is long (generally more than 24 hours).

Embodiment 1

[0048] The device and method of the present invention are used to measure the pulp concentration, fineness and density of the ore discharge and classification overflow products of a ball mill in a copper mine dressing plant of a large state-owned enterprise in Jiangxi Province.

[0049] Measure the "device weight" G according to step A 装 =400.00g, "device volume" V 装 =1000mL;

[0050] According to step B, the "pulp + device weight" G is measured 1 =1620.20g;

[0051] Manually sieve according to step C;

[0052] According to step D, the "coarse ore after sieving + water + device weight" G is measured 2 =1495.62;

[0053] According to step E, the "coarse mineral dry weight" is measured m 粗 =142.00;

[0054] Calculation according to step F.

[0055] The calculation result of embodiment 1 is:

[0056] P 细度 =56.58%, ρ 矿 =3.06g / cm 3 , R 浓度 =26.80%; the whole process only takes 1.5 hours to quickly measure the pulp concentration, mineral fineness and density at one time,...

Embodiment 2

[0061] The device and method of the present invention are used to measure the slurry concentration, fineness and density of the foam product in the secondary beneficiation operation of a copper mine dressing plant of a large state-owned enterprise in Jiangxi Province.

[0062] The determination steps are the same as in Example 1.

[0063] The "device weight" G measured at each step 装 =400.00g, "device volume" V 装 =1000mL; "pulp + device weight" G 1 =1550.51g; "Coarse ore after sieving + water + device weight" G 2 =1420.15; "coarse mineral dry weight" m 粗 =27.50.

[0064] The calculation result of embodiment 2 is:

[0065] P 细度 =86.61%, ρ 矿 =3.74g / cm 3 , R 浓度 =17.85%; the whole process only takes 1.8 hours to quickly measure the pulp concentration, mineral fineness and density at one time, which saves more than 20 hours compared with the conventional method.

[0066] The measurement result of embodiment 2 is compared with routine method measurement result as table 2. ...

Abstract

The invention relates to a device and a method for simultaneously quickly measuring the concentration of ore pulp and the fineness and the density of mineral aggregates. The device comprises an upper bottle, a lower rotary cover and a screen, wherein the upper bottle comprises a horn-shaped base; the upper end of the horn-shaped base is communicated with a tubular bottle neck; the upper end of the tubular bottle neck is communicated with a horn-shaped funnel; an overflow opening / a water inlet is formed in one side of the upper part of the tubular bottle neck; the lower end of the horn-shaped base is communicated with a tubular bottle body; external threads are matched on the outer side of the tubular bottle body; the lower rotary cover is barrel-shaped; the upper part of the lower rotary cover is open, and the bottom of the lower rotary cover is closed; internal threads matched with the external threads on the outer side of the tubular bottle body are arranged on the inner side of the upper part of the lower rotary cover, so that the lower rotary cover is in threaded connection with the outer surface of the tubular bottle body; the screen is barrel-shaped; the upper part of the screen is open, and screening holes are formed in the bottom and the side wall of the screen; the screen is connected to the lower end of the tubular bottle body. The method disclosed by the invention has the characteristics of short screening time, high efficiency and simplicity in operation; the whole process can be finished within 1-2 hours, and the concentration of the ore pulp and the fineness and the density of the mineral aggregates can be simultaneously quickly measured at a time.

Description

technical field [0001] The invention relates to a device and method for quickly measuring pulp concentration, fineness and density of mineral material at the same time, and is especially suitable for measuring various pulp product samples sampled in process investigations of nonferrous metal mine dressing plants. Background technique [0002] Conventional methods for the determination of pulp concentration and mineral fineness in non-ferrous metal mine dressing plants can generally be divided into direct determination and indirect determination, and the determination of mineral density generally adopts the pycnometer method. [0003] The direct determination method of pulp concentration is to take a sample of pulp with a sampling tool, weigh the weight of the pulp, then filter and dry the pulp to constant weight, and weigh the dry weight of the solid after cooling, according to the formula: Calculating the pulp concentration, the determination method has high accuracy, but ...
