The automatic flotation dosing machine can effectively detect and control the amount of flotation reagent added during the mineral processing production process. Some mineral processing plants still manually control the dosing valve based on the operator's work experience, resulting in high consumption of flotation reagents; overseas flotation machines do not The detection instrument of flotation reagents only indirectly measures the physical quantity. This indirect signal cannot truly and clearly reflect the actual dosage of flotation reagents used. Therefore, it is urgent to develop a type of equipment that can detect the automatic use of flotation reagents in real time. According to Choose different types of dosing machines according to the type, usage and measurement of the drug to complete automatic dosing. The common dosing methods in processing plants in my country are as follows:
(1) The flotation automatic dosing machine automatically adds a small dose of medicine. The medicine dose is as small as tens of grams per minute, and the general flow meter is not suitable for detecting such a small flow rate. According to the principle of the throttling flow meter, a small differential pressure can be used The flow meter forms a detection device, which can detect micro-flow drugs, and uses a pulse circuit to control the on-off solenoid valve to dose the drug through the drug dosing device.
(2) Flotation automatic dosing machine and quantitative dosing machine. The dosing range is 3.03000ml\/min, and the control error is 3%. For example, adding 2 oil, butyl xanthate, kerosene and other general agents. SMCJ series multi-point mineral processing program-controlled dosing The medicine machine is a system based on PLC control technology, which can be expanded to more than 200 points to complete remote setting and automatic dosing. It can be widely used in production processes such as mineral processing and extraction that require quantitative addition of liquid medicine.
(3) Flotation automatic dosing machine lime milk addition equipment. At this stage, the phenomenon of adding lime milk to adjust the pH value in mineral processing in my country troubles most mineral processing plants in my country. The fundamental reason is: high impurity content, easy calcium deposition, It has poor fluidity and high corrosivity. Most mineral processing plants use artificial addition, which not only consumes a lot of lime and pollutes the environment, but also cannot effectively manage pH and interfere with mineral processing indicators.
