Abstract

The invention provides an automatic control method for the whole process of mineral processing, which is characterized in that a piece of signal acquisition equipment is arranged on a piece of conventional mineral processing technology equipment to form a control network system, and the network structure of the system is that: a control system adopts SIMATIC PCS redundancy automatic control system, and a communication network adopts industrial ethernet annular and redundancy ROFIBUS field bus; in various operation units, crushing expert intelligent control system software, mill fuzzy control system software, hydrocyclone fuzzy control system software and flotation intelligent expert automatic control system software are respectively used to perform data processing, and optimal control, optimal operation and optimal management are performed during the production process of concentrators. The invention has the advantages of enabling digital management in the concentrators, improving the automation level in the mineral processing production process, the yield and the quality of products, the comprehensive utilization ratio of resources and the equipment capacity, saving energy and improving efficiency.

Description

technical field [0001] The invention relates to a beneficiation process method, in particular to a beneficiation automatic control method. Background technique [0002] Entering this century, the sustainable development strategy has become the top priority of the resource industry. As an important part of the resource industry, the mineral processing industry must face the two major issues of "sustainability" and "development". The pressure of "development" comes from market competition, and the pressure of "sustained" comes from the non-renewable mineral resources. With my country's entry into the WTO and the development of the national economy, mineral processing enterprises must face the staged brutal competition at home and abroad, forcing enterprises to continuously improve quality and reduce costs through various means, so as to maintain a favorable position in the industry competition. [0003] In the concentrators of developed countries, computer control of the whol...
