Jethro Baidoo,
ok, this is what I understand so far.
conveyor length 20 meters - approx. 66 ft
product - 10 kg bag of sugar on a pallet.
you only want 10 bags per conveyor section of 500 kg total plus the pallet weight.
since the weight of the product is 10 kg and add another 20 for the pallet, the conveyor should be readily available.
convey product on the conveyor for 90 minutes.
several questions for you.
What is the desired conveyor speed?
10 ft/minute, 30, 60 100??
what type of conveyor is it? chain driven, belt driven, accumulation?
what is the spacing of the rollers?
what is the size of the rollers?
what is the motor voltage?
Now that you have told me the product is sugar. what is the plant classification?
I am also assuming the motors will be TEFC - totally enclosed fan cooled and in a wash down environment.
how far will the motor be from the control panel(s)?
What is the range of ambient temperature the motors will operate at?
Lots of questions I know, but this is the information I had to have in order to spec conveyors for my customers.
