The total design is according to the requirement of Belt conveyor technical specification book,follows the relative standard and technical safety specification of current fire power plant,metallurgy,port etc.industries,uses the ripe design experience of domestic and international companies for reference,combines the spec. requirement and special climate condition and working condition of project to design and make sure the equipment can meet the requirements of safe and reliable operation and running.For long distance,large capacity and complex layout belt conveyor,we will carry out the dynamic analysis,consider the effect of several factors,such as the mechanical property of belt,the start and brake characteristics of drive unit,quality distribution of all moving part,gradient variation of running line at different segment,all moving resistance,the initial tension of belt,flexibility variation of belt,the method,position and tension of take-up unit,make a dynamics math model of belt conveyor to calculate the variation of speed,acceleration and tension at different point of belt during the process of start and brake of belt conveyor.We can predict possible dynamic danger and unsafe problems for the belt conveyor designed according to traditional static design method,and put forward improve and adjust measures to this design to decide the optimized design and control data. Many drive scheme: for long distance belt conveyor with complex running line,the normal drive scheme can not meet the requirement of start and running,we d better adopt such drive unit with controllable start and brake function to control the belt conveyor and make sure it can be started and braked according to the ideal start and brake speed curve,and in this way,we can decrease the dynamic load of belt and carrying parts.
