The general belt conveyors designed and produced by our company include TD75, DT, DT(A), DXJKD and ZJT-86 series. The overall design is based on the requirements of "Technical Specification for belt Conveyor" and follows the relevant standards and technical safety specifications of the current thermal power generation, metallurgy, port and other industries. Draw lessons from the mature design experience of belt conveyor at home and abroad, combined with the specific requirements of engineering projects, special climatic conditions and working conditions, to organize the elaborate design, in order to meet the requirements of engineering use, operation, etc., to ensure its safe and reliable operation.

My company design process mainly refer to the "JKD92 belt conveyor design selection manual". This manual is based on the JKD85 Belt Conveyor Design Selection Manual of our company. Refer to "DT75 Fixed Belt Conveyor Design Selection Manual", "DX Type Strong belt Conveyor Design Selection Manual", "80 Coal Parts Typical Design Selection Manual", "87 Coal Parts Typical Design Selection Manual", "DTI Type Fixed belt Conveyor Design Selection Manual", "DYM96 Coal transport parts typical design selection Manual ", "DTI(A) type fixed belt conveyor design selection manual" and other materials, drawing on the strengths of everyone, combined with my company over the years of design and manufacturing experience and equipment operation experience, by a number of high and intermediate professional and technical personnel jointly written; It has been widely used. For the belt conveyor with long distance, large volume and complex layout, our company will carry out dynamic analysis of the belt conveyor, and classify the conveyor belt according to the mechanical properties of viscoelastic body. Taking into account the braking characteristics of the driving device, the mass distribution of each moving body, the gradient change of each section of the line, various kinematic resistance, the initial tension of the conveyor belt, the change of the deflection of the conveyor belt, the form and position of the tensioning device and the tensioning force and other factors, the dynamic mathematical model of the conveyor is established to obtain the effect of the starting and braking process of the conveyor. The change in velocity, acceleration, and tension at different points on a conveyor belt over time. Forecast the possible dynamic danger and insecurity of the conveyer designed according to the traditional static design method, put forward the improvement and adjustment measures to the design and determine the design and control parameters.

A variety of driving scheme options: for the belt conveyor with long distance and complex lines, the conventional driving configuration scheme can not meet the starting and running requirements. It is better to use the driving device with controllable braking function to control the conveyor starting and braking according to the ideal starting and braking speed curve, so as to reduce the dynamic load of the conveyor belt and bearing parts. It mainly includes: solid state soft starting mode, AC frequency conversion speed regulating drive mode, CS controllable braking mode, soft starting mode of wound motor rotor circuit connected resistance, liquid viscous soft starting mode, hydraulic motor drive mode, speed regulating hydraulic coupler drive mode, etc.
