If I ever need to calculate approximate conveyor power, for example on simple in-plant inclined conveyors, I often do the following simple calculation. Power = t/h x lift x 2.72 x 1.3 kW From this you can easily calculate the torque, if you have the speed and pulley diameter from the following: Torque = 9.55 x power divided by pulley rpm kN-m
To determine the root mean square (continuous) torque, we first calculate the torque values required during each phase of the move profile. Torque required for constant velocity For a belt drive system, the motor torque required during constant velocity is simply the total axial force (F a ) on the belt multiplied by the radius (r 1 ) of the ...

Once you determined acceleration torque, to calculate the total torque for your motor add your frictional torque + acceleration torque. Usually, you want to add a safety factor of around 1.5-2 depending on what's available on the market.

Next it is important to calculate T2 sag (slack side tension required to prevent belt sag.) Sag is a phenomenon which can occur at the point of minimum tension in the carrying strand of a conveyor belt. On an inclined conveyor, it is usually in the vicinity of the loading zone.

the width of the belt multiplied by the length of the conveyor for the weight of both the carrying belt and the return belt. B. Chain Driven Conveyor: Chain weight from chart below multiplied by conveyor length. III. A. Roller Weight: See Chart below . III. B. Slat Weight: 1.95 pounds per lineal foot of conveyor per inch of slat width. IV.
So, the capacity of the conveyor in 5 minute is ( (50*5)/25) * 2. ie, 20 nos. So the capacity of this particular conveyor is 20 parts in 5 minutes or it will move 1 part in 15 Seconds. Hence the formula for the conveyor capacity is, ( (conveyor speed * time)/ (length of part)) * no of parts along width of conveyor.

It is difficult to find the torque required because you need to know friction, which is difficult to estimate. A company I know who makes conveyors for large animal cages assumes a friction coefficient of 1.0, in other words if you hang the load off the side the conveyor and tilt the machine up, it would be strong enough to lift it vertically.
Chain Construction The Roller Chains generator is intended to design chain drives with roller and bush chains. The chains can have single strand or multiple strands. The double-pitch chains are also supported. Typical construction of roller and bush chains is shown in the following picture. The main difference is that bush chain does not have a roller
The conveyor system is called a 2-strand roller flight floor conveyor. The conveyor track that supports the chain is fabricated from a structural channel / wear bar combination. The composition of the conveyor chain is such that each link of chain is composed of three (3) rollers -- (2) rolls that make contact with the conveyor track wear bar ...
Roller chain is used to connect two sprockets together and transfer torque. Roller chain is made up of a series of inner and outer links connected together to form a flexible strand (Figure 2).

The calculation is actually quite simple. If the speed reduction of the chain or belt drive is N:1, then the gearmotor output speed should be N times the speed calculated for the conveyor roller and the torque output should be 1/N times the torque calculated for the conveyor roller.
The pallets are fixed to an aluminium articulating block chain and are supported by precision bearing wheels (mu = 0.075).The loop is 60 mtr. The weight of moving parts and load is 140kg/mtr. and the velocity 24mtr/min. From this I calculate the torque to be 6.2 kN and using an efficiency factor of 0.85 the power needed would be 3.0 kW.
Note for (2.1) & (2.5) Chain and material sliding in scraper and drag link conveyors to calculate chain pull additional parameters must be included. F2 = Coefficiency of Friction between material to be moved and sides of trough. L = portion of loaded conveyor. M = Mass of product to be carried. H = Height of sides of trough.
