It is used in cement, chemicals, power, metallurgy, building materials, refractories, and other industrial sectors, for braking middle hardness of materials. The continuous development of science and technology, which greatly promoted the cross-penetration of different disciplines, has led to the technological revolution and the transformation of the fields of engineering, industrial production has entered a stage of development of mechatronics , but also for the roller machine electrical control system designa strong technical support. This design, in terms of security, control of the photoelectric switch on the radio, and through the control field is set to start and stop buttons to improve further on the security; in terms of reliability, the first motor starter cooling pump start the main motor control method, greatly extending the service life of the roller machine. The design elements have four parts. Firstly,through the investigation and analysis of the electrical control system of the roller machine,I determine reasonably the disign plan of the electrical control system. Secondly, through the compare and analysis of the frame system, transmission system and gap adjustment system ,I determine the transmission form and model of electromotor. Thirdly, through the parameters of the electrical components ,I determine their type. Finally,I finish the design of the electrical control system and the design of electrical control cabinet. This design is based on the electrical control system of the roller machine and the actual works. Through improving,it can be applied to industrial production and have a certain value.
