Mr. Patel,

There are ways, other than the snake, to make coal go vertical at 5500 t/h. We can talk about it at your convenience. ■

Mr. Patel,

Thank you for your post. I apologize for the late response, I was only alerted today of your post by Dr. Wohlbier. Yes it is possible to convey coal at 5500 t/h at high angle with our DSI Snake Conveyor. With the stated assumptions below I offer the following solution:

Material: Coal

Bulk Density: 0.85 t/cu-m

Design Rate: 5,500 t/h

Conveying Angle: 50 degrees

Belt width: 2800 mm

Belt Speed: 4.5 m/s

I hope this is helpful

Larry, WallyCutter,

I am curious about your solution. I have myself, in my early career, built 5000 t/h coal bucket elevators, in the form of continuous barge unloaders. They provided a strong impetus for the 1979 bureau of Mines Study. The Study ultimately took a different direction that no one anticipated including the writer. As a result we now have sandwich belt high angle conveyors that are proven now for thirty years. At the 5000 t/h rate, with coal, nothing will touch the Dos Santos Sandwich Belt solution technically and/or economically. Please consider this a challenge.
