Embodiment

[0119] Taking the grinding and classification system of the #4 mill of a concentrator as an example, a specific application of the present invention is given. The main equipment of the grinding and grading system includes: a ball mill of model QM44Φ3.6x4.5, and a hydraulic spiral classifier of model 2FLCΦ2400x14050. Its working process is as follows: the raw ore is crushed and placed in the mine bin, the vibration feeder is controlled by the frequency converter to continuously feed the ore to the belt, and then the mineral is sent to the ball mill for grinding through the belt with an electronic scale; it is controlled by an electric regulating valve The amount of sand-returning water and ore-discharging water ensures that the mixture of ore and water is fully ground in the ball mill. The pulp discharged from the ball mill flows into the hydraulic spiral classifier for particle size classification. Fine) overflows to the next process under the action of the mine water discharg...

Abstract

The invention discloses an energy-saving optimizing method for an ore grinding grading system of a concentration plant based on a decision rule. A fuzzy control technology based on intelligent control is adopted for optimally estimating the set values of three control loops of feeding volume, a sand return water volume and an ore-discharging water volume. According to the optimizing method, a decision rule set is established on the basis of applying a data-orienting decision contingency table construction method to the recorded data in production process and the incremental updating for the complete decision rule is realized on the basis of applying the incremental updating and completing method based on the decision information to the site incremental data. According to the method provided by the invention, the subjectivity and limitation of the traditional fuzzy control method are avoided, a reliable optimizing result is supplied to the set value of the key control loop of the ore grinding grading system of the concentration plant and the basis is established for realizing the energy-saving optimization of the ore grinding grading system.

Description

【Technical field】 [0001] The invention relates to an energy-saving optimization method for a grinding and grading system of a mineral processing plant, in particular to an energy-saving optimizing method for an ore grinding and grading system of a mineral processing plant based on the extraction of decision rules. 【Background technique】 [0002] Grinding and grading systems are widely used in mineral processing plants in my country. Since the grinding and grading system is one of the key links in the beneficiation process, its safe and stable operation directly affects the safety and reliability of the entire beneficiation operation. At the same time, the power consumption of the grinding and grading system accounts for about 30% to 50% of the power consumption of the plant, and its economic operation will directly affect the economic benefits of the concentrator. However, at present, the grinding and grading systems of most domestic concentrators are still in a state of ma...
