AUTOMATIC CONTROL
Numerical Control Agent Feeder
Principle
XHGY-B series numerical control agent feeder is the third generation product of Yantai Xinhai Testing and Control Co.,
Ltd. (Yantai Xinhai Mining Machinery Co., Ltd.) with the control core of Siemens PLC made in Germany, which strength-
ens the stability and reliability, and the display of high-end LCD touch screen, which is convenient for the operation.
Widely used in the precise quantitative control of flotation agent of black metals, non-ferrous metals, precious metals,
non-metallic minerals and coals, it can completely change the phenomenon of low recovery caused by manual-operat-
ed agent inaccuracy.

Features of XHGY-B Numerical Control Agent Feeder
The liquid level is controlled at the same level by height control valve, which ensures the constant flow when the sole-
noid valve is turned on;
The agent control points can be extended to 256 points, which satisfies the general grading of multiple valuable miner-
als of large processing plants;
The feeding dosage of agent for each point is 0~3000ml/min (If it is necessary, by adopting big valve, the single point
agent feeding can be up to 5000ml/min), and is suitable for the quantitative agent feeding for all kinds of acid-base
agents; for feeding of large amount of agent, it is required to apply metering pump;
Flow calibration, setting and modification can be performed through good human machine interface;
Multiple agent addition plans should be preset according to different mineral selections and capacities;
Statistics of single point shift and accumulative agent feeding can be made, and the agent dosage can be figured out in
category;
The errors between automatic agent feeding and actual measurements are less than 3%, but the precision is much
higher than that of manual operation;
Password protection is applied to parameter setting of each agent feeding point, which avoids random changes of the
parameters by people.
Safe and reliable: With power-off protection function, which avoids parameters resetting while the power on;
The system applies open and standardized structure, and the company intranet can be accessed by extended modules.
