Technical field
The present invention relates to electromechanical integration and manufacture nano-milled science and technology and control system technical field with advanced, specifically nano-milled device intelligence controls and monitoring system.
Background technology
At present, China becomes the center that World chemical production manufactures, and sand mill, dispersion machine have become the main process equipment of the sector and technological means.Along with socio-economic development and growth in the living standard, traditional equipment cannot meet people to requirement that is intelligent, automation, and in life, people are more and more higher to the security of household electrical appliance, comfortableness, energy-conservation and intelligent requirement; Equally, in the industrial production, the requirement of people to the automaticity of used electric equipment, security performance is also more and more higher, and desirable state is that electric equipment can either open intelligently, cuts out and carry out self-control according to the environment of life and production operation and requirement.Automation in recent years, intellectuality, nanometer material industry develop rapidly, user is also more and more higher for the requirement of human cost and production efficiency, Product Precision and grain fineness, user in order to enhance productivity, Product Precision, grain fineness, efficiency and reduction human cost, use sand mill on a large scale.
