Coal and rock analysis MSP9000A automatic intelligent briquette analysis system (quality control level)

AUTOMATIC INTELLIGENT COAL PETROGRAPHICANALYSIS SYSTEM

(****** high-precision CCD image photometer integrated technology)

Application:

It is used for the rapid detection of vitrinite reflectance and distribution of coal and the microscopic composition of coal and rock in coal geological exploration, coal mining, coal washing, coking and other departments and enterprises, and the comprehensive and scientific negotiation of coal quality.

Convenient guide coal washing (can recommend * * * * * * mix proportion of washing), blending (can simulate production blending find * * * * * * blending ratio) and process operation.

Technical features:

1, high precision, imported low pressure CCD, super stable: adopt high precision (16-bit) electrically-coupled CCD low pressure detector, super stable, easy to check when starting up, no need of preheating, can work continuously and steadily for a long time;

2. Fully automatic, fast and accurate results: it can really be used for rapid evaluation of coal quality in large quantities;Accuracy is better than the same products at home and abroad;

3. The evaluation of coal quality is more comprehensive: the two indexes of "vitreous reflectivity distribution" and "microscopic composition of coal and rock" can be obtained at the same time in one scan, and the evaluation of coal quality is more comprehensive;

4, special version of the coal washing plant: according to the coking customer requirements ****** mixed washing, coal washing coking two links win-win;

5. Special edition for coking plant: fully automatic ****** monitoring the mixing degree of incoming raw coal, so as to achieve the goal of avoiding losses and affecting the quality of subsequent coke;

6, coal and rock analysis function is complete: both automatic and manual (semi-automatic).The indexes of coal and rock can be analyzed, including the random reflectivity of vitreous body, ***** reflectivity, microscopic quantitative analysis of coal and rock, and the detection of customized components.At the same time, it is equipped with simulation of coal blending, average reporting, database, guidance of coal yard classification and MES system.

Technical parameters:

● linear calibration: four-standard method. The measured values of the four standard samples in the range of 0-1.72% at different temperatures are always straight lines. The difference between the measured values of any standard samples and the standard values should not exceed ±0.02% specified by the national standard.****** in similar instruments;

● stability: ****** in similar instruments;The standard sample of gadolinium and gallium was measured at 23℃, and the range of single point fluctuation within 30 minutes was 0.005%, far less than the national standard of no more than 2% (equivalent to 0.034%) within 30 minutes.

● sensitivity: 16-bit high precision, that is, the minimum discernable reflectivity change of 0.00005%, far better than the national standard provisions of 0.01%;

● filter single ****** : measure the main peak at 546nm and the half peak width at 8nm;

● measurement area: measurement area of 2 microns, has been the smallest of similar equipment, the quality group of measurement mirror more pure;

● dark current: corrected, ***** is 0;

Application in coal washing production:

1. Evaluation of pre-purchased coal: judge the real quality of pre-purchased coal from the two aspects of metamorphism degree and coal and rock composition, whether it is a typical coal, etc.Combined with the conventional index can guide the coal purchase scientifically;

2. Check the incoming raw coal: it can quickly and accurately identify the composition of single mixed coal and coal-rock activity-inert ratio, and comprehensively and scientifically evaluate the coal quality;Note: according to incomplete statistics, every year only one item, the domestic enterprises lost a staggering number, as little as one million, more than one hundred million yuan;

3. Guide mixing washing proportion of ****** : according to the requirements of coking users to seek mixing washing proportion of *****.It can not only guarantee the acceptance of raw coal for coking users and the quality of coke produced, but also realize the profit of washing industry. At the same time, it makes scientific use of various so-called "poor coal".Effectively protect the dwindling coal resources, truly realize the coal washing and coking national resources protection of the three parties win;

Application in coking production:

1. Evaluation of pre-purchased coal: judge the real quality of pre-purchased coal from the two aspects of metamorphism degree and coal and rock composition, whether it is a typical coal, etc.Combined with the conventional index can guide the coal purchase scientifically;

2. Check the incoming raw coal: it can quickly and accurately identify the composition of single mixed coal and coal-rock activity-inert ratio, and comprehensively and scientifically evaluate the coal quality;Note: according to incomplete statistics, every year only one item, the domestic enterprises lost a staggering number, as little as one million, more than one hundred million yuan;

3. Guide reasonable stacking in coal yard: make use of the principle of similar vitrinite reflectivity distribution and similar coal quality to reasonably arrange stacking in coal yard to prevent the unknown secondary mixed coal in the factory from causing large fluctuations in production;

4. Monitor the ratio of coal entering the furnace: get the true proportion of "active matter" with different coking characteristics, without being confused by the appearance of "surface coal proportion".Prevent large fluctuations in coke quality and mismatches and missing matches in other production links;, can effectively stabilize coke production

5. refined coal and rock blending: guide coal blending from the perspective of coal petrology, coarse refining ratio operation, save huge cost, reduce waste.
