If you take material by truck at 130km/hour in a civilised country you will go to jail. ■

Dear Mr. Mohammed,

There are many fertilizer plants in India which are manufacturing Urea. This is normally conveyed at 1 mps, but one can also go up to 1.25 mps or if the conveyor is exceptionally long, you can use 1.5 mps. Generally, the in-plant conveyors are very less in length and thereby the usual practice is to have 1 mps speed for Urea prills. You can refer to Urea manufacturers and plant people for more specific information.

Please note that the restriction of speed is not from conveyor design and operation point of view but it is due to delicacy of material for which more impact at transfer point is not desirable from economy point of view.

The above practice is generally inline with the international practice.

Regards,

Ishwar G Mulani.

Dear Mr. Mohamed,

The optimum speed of a conveyor depends on many factors (capacity, length, inclination of the conveyor, etc...). The last one we delivered for an Egyptian client working in urea was running 1,2 m/s and no problems were recorded since then.
