Abstract
СПОСОБ МОКРОГО ПОМОЛА МИНЕРАЛЬНОГО СЫРЬЯ, включающий измельчение , двухступенчатую гидроклассификацию измельченного материала на тонкие и грубые фракции, подачу продуктов разделени в мельницу о тличающийс тем, что, с целью снижени затрат на измельчение , грубые фракции гидроклассификации измельчают в мельнице второй стадии, объедин ют их с тонкой фракцией первой ступени гидроклассификации и вторично гидрбклассифицируют с получением тонкого, кондиционного по крупности и влажйости продукта, который вывод т из цикла: измельче (Л ни .A method of wet grinding of mineral raw materials, including grinding, two-step hydroclassification of the crushed material into fine and coarse fractions, feeding the separation products into the mill, which is such that, in order to reduce the costs of grinding, coarse hydroclassification fractions crushed into a second-stage mill, cooked into a second stage, created into a mill, created a melter, and reduced the cost of grinding. the fine fraction of the first stage of hydroclassification and the second hydrclass is produced to obtain a thin, conditional in size and moisture content of the product, which is derived from the cycle: (L neither.

Изобретение относитс к технологии мокрого измельчени минерального сьфь и может быть использовано в металлургической, цементной, химической и других отрасл х промышленноети при подготовке сьфь к переработке по способу спекани .The invention relates to the technology of wet grinding of mineral coal and can be used in the metallurgical, cement, chemical and other spheres of industrial networks in the preparation of coal for processing by sintering.
Цель изобретени - снижение затрат на измельчение;The purpose of the invention is to reduce the cost of grinding;
Способ осуществл ют следующим образом .The method is carried out as follows.
В ме|1ьницу первой стадии подают исходное сырье и жидкую фазу в количествах , обеспечивающих заданное содержание влаги в готовом продукте в цикле измельчени . Измельченный материал классифицируют, нап4)имер.In the first-stage meat, the feedstock and the liquid phase are fed in quantities that provide the specified moisture content in the finished product during the grinding cycle. The ground material is classified, nap4) imer.
в гидроцйклоне первой ступени на тонкий продукт с повышенным содержанием влаги и грубую фракцию пониженной влажности.in the first stage hydrocyclone for a thin product with a high moisture content and a coarse fraction of low humidity.
Грубую фракцию направл ют в мельницу второй стадии и измельчают без подачи жидкой фазы. Разгрузку мельницы и тонкий продукт первой ступени объедин ют и классифицируют в гидроциклоне второй ступени. При этом получают грубую фракцию, которую возвращают на доизмельчение в мельницу второй стадии, и тонкую фракцию - кондиционный по крупности и влажности продукт, которую вывод т из цикла измельчени .The coarse fraction is sent to the mill of the second stage and crushed without feeding the liquid phase. The unloading of the mill and the first stage fine product are combined and classified in a second stage hydrocyclone. A coarse fraction is obtained, which is recycled to a second stage mill for grinding, and a fine fraction is a conditional in size and moisture product that is withdrawn from the grinding cycle.
