Step 5 Calculate weight on belt Your solution Using the belt speed established in STEP 4, you can now calculate the weight on a belt using the simple formula below. Conveyor length Worked Example 70 tonnes/hr x 0.28 ÷ 0.7 m/s = 28 kg/m Your Solution tonnes/hr x 0.28 ÷ m/s = kg/m Step 6 Calculate belt pull required Conveyor length 8.8 m x 14 = + + + + x 0.7 = x 0.7 = + + x 20 = x 20 = x 20 = 3 m 28 kg/m = x 20 = 172 x 0.7 = + + 1680 x 20 = = N EK1500 x 45 = x 0.7 = Belt pull required EK1200 x 36 = + 2006 N = = N x 17.5 = x 26.6 = x 36 = x 45 = + + + + + x 0.7 = x 0.7 = x 0.7 = x 0.7 = x 0.7 = + + + + + x 20 = x 20 = x 20 = x 20 = m x kg/m Conveyor Rise x weight on belt m x 20 = kg/m = Snub drive EK900 = N EK1500 x 14 = Conveyor length weight on belt Standard drive x 17.5 = 154 x 26.6 = Conveyor length 8.8 m x x 0.7 = weight on belt 28 kg/m + Conveyor Rise x weight on belt 40 EK600 EK450 EK1200 EK900 = = N N = N = N N NB maximum belt pull that can be transmitted by drive drum Please note that these calculations do not include EASIKIT300. Worked Example m Belt pull required To establish the correct motor/gearbox unit for your application you will need to calculate the Newton force required to drive your conveyor. Using the information you have already obtained in STEPS 1 and 5 this can be calculated as shown in the following example. EK600 EK450 N 4150N 3749N 3749N 7880N 7880N 3749N 7880N 7880N
