Several drug delivery methods for automatic dosing machines

The automatic dosing machine of medicines can independently add different types of automatic medicine dosing machines according to the type of medicine, the amount of medicine required and whether it is metered and tested. The wide range of medicine dosing methods in China's mineral processing plants are:

(1) Autonomous addition of small-measurement testing of drugs. The demand for drugs is as small as tens of grams per minute, and ordinary steam flow meters are not suitable for accurate measurement of this type of flow. Based on the basic principles of throttle valve steam flow meters, A level pressure steam flow meter is used to form a detection device to accurately measure the flow rate of drugs, and a single pulse circuit is used to control the switch relay of the automatic dosing device to add the drug.

(2) Quantitative analysis of the independent drug dispensing machine. The drug dispensing range is 3.0-3000mL\/min, and the control error is ±3 percentage, such as adding 2 oil, diacetate, kerosene and other common drugs. The automatic drug dispensing machine is based on PLC control professional It is flexible, can be expanded to more than 200, and can be remotely operated to set values ​​and add drugs independently. The system can be widely used in mineral processing, flotation reagents, extraction and other production processes that require quantitative analysis of the addition of liquid drugs.

(3) Automatic dosing machine hydrated lime adding facilities. The hydrated lime added by the automatic dosing machine for pH adjustment of flotation reagents in China has always been a problem in most mineral processing plants in China. The important reason is that hydrated lime contains high impurities and is easy to form calcium. , poor fluidity and high corrosion. Most mineral processing plants choose to add artificially, which not only consumes a lot of lime powder and causes air pollution, but also the pH cannot be effectively controlled, which harms the flotation reagent index value.
