Дл  опытов используют хлористый калий , получаемый флотационным обогащением , и сульфат кали , полученный методом кристаллизации. Крупность продукта - 0,25-0 мм. Содержание класса менее 0,1 мм в образцах хлористого кали  составл ет 17,3 и 1,Р мас.% соответственно мелкозернистый и обеспыленный флотоконцентрат, у сульфата кали  содержание класса менее 0,1 мм составл ет 9,3 мас.%.Potassium chloride obtained by flotation concentration and potassium sulfate obtained by the crystallization method are used for the experiments. The size of the product is 0.25-0 mm. The content of the class is less than 0.1 mm in potassium chloride samples is 17.3 and 1, P wt.%, Respectively, fine-grained and dust-free flotation concentrate, for potassium sulfate, the content of the class is less than 0.1 mm, it is 9.3 wt.%.

циламина. Результаты опытов приведены в таблице.cylamine. The results of the experiments are given in the table.

Как видно из приведенных в таблице данных, непыл щий мелкозернистый хлористый калий может быть получен по предлагаемому способу пылеподавлени  при использовании препарата Привес-40 и Полиглицерина при расходе 3,0 кг/т (опыты 6 и 9), при этом достигаетс  высока  эффективность антислеживани  и достаточно низка  влажность готового продукта (0,6-0,7 мас.%). При уменьшении расхода до 2,0 кг/т пылимость продукта остаетс  выше допустимой. Увеличение расхода до 4,0 кг/т не приводит к значительному уменьшению пылимости, а влажность готового продукта становитс  близкой к предельно допустимому по техническим услови м значению 1,0 мас.%. При использовании сочетани  глицерина и оксиэтилированной кислоты (предлагаемый способ) дл  получени  непыл щего мелкозернистого хлористого кали  требуетс  более высокий расход пылеподавлени  - до 5,0 кг/т, при этом недопустимо высока  влажность готового продукта (свыше 4 мас.%) и более низкие значени  эффективности антислеживани  (опыт 4).As can be seen from the data in the table, non-dusty fine-grained potassium chloride can be obtained by the proposed method of dust suppression using the drug Gain-40 and Polyglycerol at a flow rate of 3.0 kg / t (experiments 6 and 9), while achieving high curing efficiency and the moisture content of the finished product is quite low (0.6-0.7 wt.%). By reducing the flow rate to 2.0 kg / ton, the dustiness of the product remains higher than permissible. An increase in consumption to 4.0 kg / t does not lead to a significant decrease in dustiness, and the moisture content of the finished product becomes close to the maximum permissible by technical conditions value of 1.0 wt.%. When using a combination of glycerol and ethoxylated acid (the proposed method), to obtain non-dusty fine-grained potassium chloride, a higher consumption of dust suppression is required — up to 5.0 kg / ton, while the humidity of the finished product is unacceptably high (over 4 wt.%) And lower anti-tracking efficacy (experiment 4).

При получении непыл щего обеспыленного хлористого кали  достаточен расход предлагаемых пылеподавителей 0,5 кг/т (опыты 16 и 19), уменьшение расхода до 0,3 кг/т (опыты 15 и 18) не приводит к образованию непыл щего продукта, увеличение до 0,7 кг/т (опыты 17 и 20) не приводит к значительному дальнейшему (по сравнению с 0,5 кг/т) уменьшению пылимости продукта. В то же врем  дл  получени  непыл щего продукта с использованием известных пылеподавителей требуетс  их расход 1,2 кг/т (опыты 12-14).Upon receipt of dust-free, dust-free potassium chloride, the proposed supply of dust suppressors of 0.5 kg / t is sufficient (tests 16 and 19), a reduction in consumption to 0.3 kg / t (tests 15 and 18) does not lead to the formation of dust-free product, an increase to 0 , 7 kg / t (experiments 17 and 20) does not lead to a significant further (as compared with 0.5 kg / t) decrease in the dustiness of the product. At the same time, to obtain a non-dusting product using known dust suppressors, their consumption is 1.2 kg / t (tests 12-14).

При получении непыл щего мелкозернистого сульфата кали , пылимость которого занимает промежуточное положение среди приведенных калийных солей, достаточно использование предлагаемых пылеподавителей в количестве 2,0 кг/т (опыты 25 и 29), в то врем , как необходимый расход глицерина в сочетании с оксиэтилированной кислотой в 2 раза выше (опыт 23).Upon receipt of non-dusty fine-grained potassium sulfate, the dustiness of which occupies an intermediate position among the potassium salts, the use of the proposed dust suppressors in an amount of 2.0 kg / t (tests 25 and 29) is sufficient, while the required consumption of glycerol in combination with ethoxylate acid 2 times higher (experiment 23).

Использование предлагаемый пылеподавителей способствует получению менее слеживающегос  продукта - эффективность антислеживани  при использовании пылеподавителей , содержащих сочетание глицерина и полиглицерина, выше, чем при использовании глицерина и оксиэтилированной кислоты (опыты 4, 14, 23, 6, 9. 16.19, 25 и 29).The use of the proposed dust suppressors helps to obtain a less caking product - the effectiveness of anti-tracking when using dust suppressors containing a combination of glycerol and polyglycerol is higher than using glycerol and ethoxylated acid (experiments 4, 14, 23, 6, 9. 16.19, 25 and 29).

Таким образом, использование предлагаемого способа пылеподавлени  позвол ет не только повысить эффективность пылеподавлени  и уменьшить слеживае- мость солей, но и снизить расход пылепода- вител . Экономический эффект в расчете наThus, the use of the proposed method of dust suppression not only improves the efficiency of dust suppression and reduces the caking of salts, but also reduces the consumption of dust suppressor. The economic effect based on

производство 1 млн. т. 95% хлористого кали  достигаетс  за счет улучшени  экологических условий при производстве и перегрузке минеральных удобрений. Предлагаемый пылеподавитель может быть использован при производстве непыл щих минеральных удобрений.The production of 1 million tons. 95% of potassium chloride is achieved by improving the environmental conditions during the production and transshipment of mineral fertilizers. The proposed dust suppressor can be used in the production of non-dusting mineral fertilizers.
