Nucleon Balance

The basic components of the grinding and classification process control system: (1) grinding and classification process control system.which is composed of the following three basic control aspects: given control of the amount of ore grinding concentration control, grading the indiscriminate flow concentration (particle size) control. (2) the system input. : (1) grinding mill ear value. It is primarily to select the intensity and frequency of the mill operation when the internal sound, and then converted into an electric signal and sent to the controller (PLC), as judged by the mill whether up belly or idling basis, and can also be used as to control amount of ore outer set value;? mill power (voltage and current). Whether it can reflect the mill running in the best condition, general power, high efficiency mill mill; (3) belt scale (the Nucleon Balance or electronic scales). Do To reflect the instant flow of ore into the mill, the amount of processing units in total;? (do electromagnetic flowmeter? but not ball mill, impact crusher). For back water sand mine discharge water flow detection; the? the grader overflow (or coexistence) concentration detection.

(3) Output control amount. : control to the ore. Constant to mine mine is artificially set to a given value, this control method used in the non-ferrous metal mining flotation plant the more; variable value control ore given value is based on the mill load The change automatically modified at any time, this control method used in most of the ferrous metal mine concentrator the more. Controller settings and measured values?of the ore, the adjustment to the material machine engine speed, so as to control the mill to the ore. The multiple feeder to the mine, the feeder can be used automatically switch the way; the? grinding control concentration. A direct impact to the water mill grinding efficiency and quality, generally use the direct measurement of the concentration of the slurry in the mill, the mill with total ore is proportional to the control and water control program.

The mill pulp density control object depends primarily on the amount of sand back to add the total to the amount of ore in the mill (new to the amount of ore) and new water system based on the total to the does amount of ore by solid-liquid ratio control;? mill row of ore concentration control. The system is based on the total amount of ore before water issue comprehensive signal control to change the mill row of ore feed water regulating valve to the water, the drain mine water supply is proportional to the total amount to the mine, to overflow the row of ore concentration mill track stability; Another way is to measure the concentration directamente put overflow pulp density, row of ore to adjust the amount of water, so as to achieve the purpose of stable overflow row of ore concentration. (4) The grinding efficiency detection. Mill power, sound intensity and load.
