Method and device for measuring state of substances in drum type grinding machine

Abstract

The invention discloses a method and a device for measuring the state of substances in a drum type grinding machine. The method comprises the following steps of: detecting noise signals generated during operation of the grinding machine, high-power vibration signals of the grinding machine, active power signals of a main motor of the grinding machine, current signals of the main motor of the grinding machine, rotating speed signals of the grinding machine, humidity signals of materials in the grinding machine, temperature signals of the materials in the grinding machine, and fineness signals of the materials in the grinding machine; processing input signals by adopting a constructed neural network for measuring the state of the materials in the grinding machine, and obtaining variables representing the operating state of the grinding machine, such as the amount of the materials in the grinding machine, the amount of water, the amount of a grinding medium and the concentration of ground ore. The invention has the advantages that the variables of the operating state of the grinding machine are obtained by selecting corresponding detecting signals for different operating conditions of the drum type grinding machine and adopting a corresponding data processing method, so that the problem that the operating state of the grinding machine can not be measured in long term is solved and a foundation is laid for automatic control and optimization of the grinding machine. The invention can be widely applied to the industries such as power, building materials, mine metallurgy and ceramics.

Description

technical field [0001] The invention relates to the technical field of automatic measurement, in particular to a method and device for measuring the state of matter in a barrel mill. Background technique [0002] The barrel mill is widely used in electric power, building materials, mining metallurgy, ceramics and other industries. The barrel mill has the advantages of simple structure and convenient maintenance. However, because the operator knows too little about its operating status, the barrel mill The operation has been using manual judgment and manual operation. At present, although domestic and foreign have researched and produced material level sensor transmitters for coal pulverizers in power plants, material level sensor transmitters for cement plant mills, and iron ore The electric ear of the mill, but due to factors such as materials, processes, dry or wet production, the operating status of the entire mill is unknown, and there is no control over the management o...
