Известен способ получени  гидрофобизированного мела, например, ИСпользуемого в качестве на1полнител1 дл  поливинилхлоридных изделий -путем помола его Совместно с поверхностно-активными веществами.A known method for producing a hydrophobized chalk, for example, IS used as a filler for polyvinyl chloride products, is by grinding it Together with surfactants.

Целью изобретени   вл етс  улучшение распределени  гидрофобизатора и интенсификацИ-и процесса.The aim of the invention is to improve the distribution of the water-repellent agent and the intensification of the process.

Это достигаетс  тем, что в сырье добавл ют в количестве 10-70% от веса предварительно гидрофобизированный молотый мел, а после перемешивани  осуществл ют фракционное разделение .готового продукта.This is achieved by adding pre-hydrophobised ground chalk to the raw material in the amount of 10-70% by weight, and after mixing, fractional separation of the finished product is carried out.

Добавка в сырье предварительно молотого гидрофобизированного мела обеспечивает необходимое содержание гидрофобизатора в получаемо ,м сепарированном меле.The additive in the raw material of pre-ground hydrophobized chalk provides the necessary content of water-repellent agent in the resulting, m separated chalk.

Предлагаемый способ улучшает гидрофобизацию частичек мелкодисперного мела вследст1вие увеличени  поверхности контакта с мелкодисперсным мелом нри установленном или уменьшенном расходе гидрофобизатора. Скорость /перемешивани  н контакта гидрофобных частичек с .негидрофобными увеличиваетс  в 2-3 раза. В результате этого увеличиваетс  производительность ломола мела, полностью ликвидируетс  агрегир01вание частиц 1мела и прилипание их к .мелющим телам.The proposed method improves the hydrophobization of the fine chalk particles by increasing the surface of contact with the fine chalk at a fixed or reduced consumption of the water repellent agent. The speed / mixing of the contact of hydrophobic particles with non-hydrophobic particles increases by a factor of 2-3. As a result of this, the productivity of chunks of chalk is increased, the aggregation of particles of chalk 1 and their adhesion to shaving bodies is completely eliminated.

В качестве гидрофобизатора дл  предварительного приготовлени  мела и-епользуют, например , монокарбоновые л ирные кислоты с числом углеродных атомов Сю-С2о.As a hydrophobic agent for the preliminary preparation of chalk, for example, monocarboxylic acidic acids with the number of carbon atoms of Cyu-C2o are used.

Помолотый и гидрофобизированный мел из размольного устройства, например шаровой мельницы, воздушным потокам раздел етс  на гидрофобный молотый и гпдрофобпьп сепарированный мел. Последний используетс The ground and hydrophobic chalk from the grinding device, for example a ball mill, is divided into air flow into hydrophobic ground and gpdrophob separated chalk. The latter is used

как готовый продукт, а гидрофобный :мсл в количестве 10-70% от веса исходного продукта подаетс  в размольный агрегат.as a finished product, and hydrophobic: MSL in the amount of 10-70% of the weight of the initial product is fed to the grinding unit.

При этом улучшаетс  степень гидрофобизадии , повышаетс  производительпость мельнид,This improves the degree of hydrophobic behavior, increases the productivity of mills,

не происходит агрегировани  мела и залипани  рабочих органов и мелющих тел.there is no aggregation of chalk and sticking of the working bodies and grinding bodies.

Способ (Получени  тидрофобизировапного мела дл  производства, например, поливнпилхлоридных изделий, путем помола его совместно с поверхностно-активными веществами , отличающийс  тем, что, с целью улучшени  распределени  гидрофобизатора и иптенсификащии троцесса, е сырье добавл ют в количестве 10-70% от веса предварительно гндрофобизированный молотый мел, а после нервмешивани  осуществл ют фракциопное разделение готового продукта.Method (Production of tidrofobizirovany chalk for the production of, for example, multifunctional chloride products, by grinding it together with surfactants, characterized in that, in order to improve the distribution of water repellents and the attenuation of the process, the raw material is added in the amount of 10-70% by weight previously Ground-ground ground chalk, and after neural mixing, fractionated separation of the finished product is carried out.
