We offer several drag conveyor diameters for varying capacities.
You can figure out which diameter is right for you using a function of your product's bulk density and your desired rate of conveyance.
Let's say you want to convey 50,000 lb/hr of cornmeal which has a bulk density of 40 lb/ft3.
You divide 50,000 lb/hr by 40 lb/ft3 which equals 1,250 ft3/hr.
Since you want a conveyor that can move at least 1,250 ft3/hr of cornmeal, that puts you comfortably within a 6" diameter system.
Or you can reverse the function:
Let's say you want to know the maximum amount of cornmeal you can convey with a single 6" diameter system.
You take cornmeal's density of 40 lb/ft3 and multiply by 1,400 ft3/hr which equals 56,000 lb/hr.
This means you could move 56,000 lb/hr of cornmeal in a 6" diameter system.
Up to 280 ft3/hr (or 8 m3/hr)
3″ diameter drag conveyor systems are great for malted barley. It is the popular choice for seeds and crumbs as well.
Up to 650 ft3/hr (or 18 m3/hr)
4" diameter drag conveyor systems are a great fit for green and whole bean roasted coffee, oats, pecans and almonds.
Up to 1,000 ft3/hr (or 28 m3/hr)
5" diameter drag conveyor systems are great for moving pet food, breakfast cereal, peanuts, whole walnuts and cashews.
Up to 1,400 ft3/hr (or 40 m3/hr)
6" diameter drag conveyor systems are great for any application in scaled process systems like ground coffee or bulk powder.
