Description
Изобретение относитс к способам управлени процессом измельчени материала после обжига, осуществл емого во вращающихс печах с предварительным нагревом исходного материала отход щими газами печи в теплотехнических аппаратах, например, в шахтных подогревател х, и может быть использовано в горно-химической промышленности.The invention relates to methods for controlling the process of grinding material after firing, carried out in rotary kilns with preheating of the starting material with kiln flue gases in heat engineering apparatus, for example, in mine preheaters, and can be used in the mining and chemical industry.
Известен способ управлени процессом измельчени путем поддержани посто нства исходного питани мельниц. Датчиком системы, реализую щей указанный способ, вл ютс конвейерные весы, сигнал с которых поступает на вторичный прибор и на регул тор . При отклонении от задани регул тор воздействует через исполнительный механизм на регулирующий орган, который мен ет подачу сырь на измельчение fl.There is a known method of controlling the grinding process by maintaining the initial feed of the mills. The sensor of the system that implements this method is belt scales, the signal from which is fed to the secondary device and to the controller. In the event of a deviation from the reference, the regulator acts through the actuator on the regulator, which changes the feed of the raw material for grinding fl.
Однако управление процессом измельчени по указанному способуHowever, the control of the grinding process according to this method
не обеспечивает стабилизац.ии гранулометрического состава пульпы после измельчени ,так как требуетс частое вмешательство е процессе во избежание недогрузок и перегрузок агрегата .It does not stabilize the granulometric composition of the pulp after grinding, as it requires frequent intervention in the process in order to avoid underloading and overloading of the unit.
Наиболее близким к предлагаемому по технической сущности вл етс способ управлени процессом измельчеto ни материала после обжига, осуществл емого во вращакхцихс печах с предварительным нагревом исходного материала отход щими газами печи, преимущественно в нахтных подогревател х, The closest to the proposed technical essence is the method of controlling the process of grinding the material after firing, carried out in rotary kilns with preheating of the source material with the exhaust gases of the kiln, mainly in heating heaters,
15 включающий изменение расхода раствора в зависимости от расхода материала в мельницу. При этом регул тор соотношени руда-вода поддерживает заданное соотношение дл обеспечени 15 which includes a change in the flow rate of the solution depending on the flow of material in the mill. At the same time, the ore-water ratio controller maintains the predetermined ratio to ensure
