Abstract
The invention discloses a mineral powder production fineness online intelligent monitoring system and a control method thereof.The mineral powder production fineness online intelligent monitoring system comprises an APC server, a factory control network, an Ethernet switch, a field control network and a slag production DCS, wherein the APC server is externally connected with the network to be connected with an engineer station, an operator station and an online fineness analyzer operation station through the factory control network; in the slag production DCS, a field device connected with a controller input and output module is connected with a field control network, a factory control network and the field control network are connected through an Ethernet switch network. The system further comprises a laser online fineness analysis system connected with the online fineness analyzer operation station through the factory control network. Scattered light generated by the laser beam penetrating through the to-be-detected sample is converted into a scattered light energy distribution diagram, and calculation is performed to obtain the fineness distribution of the sample. The mineral powder specific surface area can be detected in real time, closed-loop control is conducted on the mineral powder specific surface area in combination with the intelligent adjusting powder concentrator, and the quality of finished mineral powder is accurately controlled.
Description
technical field [0001] The invention belongs to the field of intelligent control systems, and in particular relates to an online intelligent monitoring system for mineral powder production fineness and a control method thereof. Background technique [0002] The production process of slag grinding is a highly related and complex process engineering. The specific surface area of slag powder is an important quality index of the finished product, and it is very important to control it within the range of process requirements. In the prior art, the measurement is generally carried out by on-site manual testing, but this will lead to a large hysteresis in the measurement of the specific surface area of the ore powder, and it is impossible to guide and adjust the speed of the separator in time. The online fineness analyzer can realize the online detection of the specific surface area of ore powder, and it can be integrated with the advanced control system to realize the onlin...
