Description

Изобретение относитс  к установкам дл  измельчени  твердых волокнистых и в зких материалов, состо щим из струйной мельницы, комнрессора, дозаторов, классификатора, фильтров, пылеотделнтел  и вентил тора.The invention relates to a grinding plant for solid fibrous and viscous materials consisting of a jet mill, compressor, metering devices, classifier, filters, dust separator and fan.

Известные установки такого рода непригодны дл  помола трудноизмельчаемых нехрупких материалов.Known installations of this kind are unsuitable for grinding hard-to-crumb, non-friable materials.

В описываемой установке трудноизмельчаемый материал превращают в хрупкий посредством переохлаждени  его сжиженным инертным газом, дл  чего в установке применены ресивер-холодильник, теплообменник , вихревой разделитель и камера дл  охлаждени  исходного материала с дозатором хладоагента и выносным электромагнитным вибратором.In the installation described, the difficult to grind material is transformed into brittle by supercooling it with a liquefied inert gas, for which the receiver-cooler, heat exchanger, vortex separator and chamber for cooling the source material with a refrigerant dosing unit and an external electromagnetic vibrator are used in the installation.

На чертеже показана принципиальна  схема установки.The drawing shows a schematic diagram of the installation.

Измельчаемый- материал подаетс  из бункера / в камеру охлаждени  2. Туда же из дозатора 3 подаетс  хладоагент. Переохлажденный материал с помощью электромагнитного вибратора 4 и дозирующего устройства камеры охлаждени  раВ юмерно и непрерывно подаетс  по теплоизолированным стекл нным трубам в эжекторы помольной камеры 5. В эту же камеру по трубам 6 поступает знергоноситель-сжатый газ, охлажденный в ресивере-холодильнике 7 с помощью отход щих из камеры охлаждени  2 газов.The material to be ground is fed from the hopper / into the cooling chamber 2. There is also a refrigerant from the metering unit 3. The supercooled material is electrically and continuously fed via thermally insulated glass tubes to the ejectors of the grinding chamber 5 using an electromagnetic vibrator 4 and the metering device of the cooling chamber 5. The carrier-compressed gas cooled in the receiver-refrigerator 7 is fed into the same chamber 6 using waste 2 gases from the cooling chamber.

Частицы материала разгон ютс  в трубах мельницы и, сталкива сь друг с другом, в камере 5 подвергаютс  измельчению. Смесь материала с газами поднимаетс  по трубе 8 в классификатор 9. Крупные частицы по трубам 10 поступают на домол; маткие унос тс  потоком воздуха в пылеотделитель П. Продукт, отделенный пылеотделителем , поступает в приемник-теплообменник 12, а воздух отсасызаетс  вентил тором и через фильтр 13 выбрасываетс  в атмосферу. Дл  повыщени  эффективности работы мельницы и поддержани  отрицательной температуры в трубе 5 и классифакаторе 9 в мельницу дополнительно подаетс  холодный воздух, получаемый методом разделени  наThe particles of the material are accelerated in the pipes of the mill and, colliding with each other, are crushed in chamber 5. The mixture of material with gases rises through pipe 8 to the classifier 9. Large particles through pipes 10 are fed to the final grinding; untreated air is carried to the dust separator P. The product separated by the dust separator enters the receiver-heat exchanger 12, and the air is sucked off by the fan and is emitted through the filter 13 into the atmosphere. In order to increase the efficiency of the mill and maintain the negative temperature in the pipe 5 and the classifier 9, cold air is additionally supplied to the mill.
