Embodiment Construction

[0042] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0043] figure 1 It is a schematic diagram of the cement mill system in one embodiment, as shown in the figure. A cement milling system, including a steady flow bin, a roller press, a ball mill, a first powder separator, a second powder separator and a dust collector. The material belt is conveyed to the bucket of the roller press, and fed into the roller press through the bucket of the roller press. The coarse particle material from the powder classifier returns to the steady flow bin, and the small particle material enters the ball mill, and after being pulverized by the ball mill, enters the se...

Abstract

The invention relates to an automatic optimizing control system of a cement mill system. The automatic optimizing control system is used for controlling the operation of the cement mill system and comprises a total feeding module, a double-lever feeding device module, a circulating fan module, a V-type inlet valve baffle, a powder concentrator module, a system fan module, a specific surface area prediction module and a specific surface area automatic optimizing module, wherein the total feeding module is used for controlling the total feeding amount according to the bin weight of a steady flowbin and a grinding hopper lifting current; the double-lever feeding device module is used for controlling the opening degree of a feeding device according to a roller press current and a roller presslifting current; the circulating fan module is used for controlling the rotating speed of a circulator according to the grinding hopper lifting current and a main motor current; the V-type inlet valve baffle is controlled according to the total feeding amount; the system fan module is used for controlling the rotating speed of a powder concentrator according to the fineness quality; the system fan module is used for controlling the rotating speed of a system fan according to the fineness quality; the specific surface area prediction module takes corresponding measures according to the changetrend of the specific surface area; and the specific surface area automatic optimizing module is used for predicting and controlling a plurality of process parameters in real time and calculating thespecific surface area. The automatic optimizing control system of the cement mill system can increase the yield, reduce the specific energy consumption, stabilize the quality and improve the economicbenefits of cement production enterprises.

Description

technical field [0001] The invention relates to the field of cement production, in particular to a cement mill system and its automatic optimization control system and method. Background technique [0002] The cement production process includes three processes: cement raw material grinding, cement firing and cement grinding. [0003] Among them, the process of cement mill is: batching, grinding, powder selection, transportation. According to different cement varieties, set the corresponding material ratio, the prepared mixed material enters the steady flow bin and then feeds the roller press, the material from the roller press enters the V-type powder separator, and the coarse particles are selected by the V-type. The lower part of the powder mill returns to the steady flow chamber, and the smaller particles enter the ball mill. The material after being ground by the ball mill enters the O-Sepa powder separator (the O-Sepa powder separator was developed by Japan Onoda Comp...
