Calculation Method Of Conveyor Belt Length

The length of the conveyor belt refers to the length of the conveyor belt when it is flattened. Generally, Produce manufacturers give labels when they produce (Produce). However, when the labels are unclear or not marked, how to calculate the summary (zǒng jié) The formula is now introduced as follows. The mining conveyor belt moves according to the principle of friction transmission. It is suitable for conveying powdery, granular, small lumps and bagged materials with a bulk density of less than 1.67/ton/m3 and easy to pick up, such as coal, Crushed stone, sand, cement, fertilizer, grain, etc. The support roller can transport various bulk materials with a bulk density of 1.0 to 2.5 tons/m3, with a production bandwidth of 500, 600, 800, 1000, 1200, 1400, 1600 and other specifications, and the transmission power ranges from 1.5KW to 800KW. The belt speed is 0.63, 0.8, 1.0, 1.25, 1.6, 2.0, 2.5, 3.15, 4.0 m/s, etc. The temperature of the material being conveyed by the support roller is generally less than 60℃. The length and assembly form of the machine can be determined according to user requirements. The transmission can be electric rollers or a drive device with a drive frame. 1 Common formula and experience (experience) formula introduction Common formula L=l/2N experience (experience) formula L=N. The length of the n-type conveyor belt, m; Ro is the radius of the roller (gǔn) core of the coiling conveyor belt, m; RTI is the maximum radius of the conveyor belt, m; the thickness of the conveyor belt, m; N is the conveyor belt coiling The number of turns. 2 The origin of the experience formula The shape of the conveyor belt when it is coiled is a spiral, see 1.1 The side of the rolled conveyor belt is relatively thin due to the thickness of the conveyor belt, which is generally between 0.010 and 0.030 m. We might as well regard each spiral on 1 as a circle composed of one after another, see 2.2 Side simulation (definition: virtual of real thing or process) calculation of rolled conveyor belt. Not=2sI Length of the second circle: =2si Length of the third circle: =2si Length of the Nth circle: =2siIt The length of the roll is: L=LI+ + +?? + = L=】 1It ItΣ2. Not = 2s~NIL +2. Not 6Σi One. nN×N/2-JIN6=N or L=N. n3 The example shows that when the radius of the roller (gǔn) of the winding conveyor belt is 0.20m, the thickness of the belt is 0.022m, a total of 30 turns are wound, and the length of the roll is: L=NJ1=30. Not=99.85m and the actual length of the conveyor belt is: =99.50m, calculated like this /LReal×100% =/
