High Heaping Equipments
I am N.Ramakrishnan, Senior Manager Production for a fertiliser unit in South India. We are manufacturing* a complex fertiliser with 16:20 grade with Ammonia , Sulphuric and Phosphoric acids.
In the process we handle rock phosphate at one stage* which is stored in a silo. We bring rock from the nearby Chennai Harbour ,by trucks and the trucks unload the material into the silo. Wr use shovels to heap the material and* we store* about 10000 mt of rock in the silo. Rock is stored in a trapezoid form of about 2 m high and much space is left above the heaps.
I would lke to know what methods can be used to* make the heap bigger** by discharging the material from the top. Though the silo roof can accoodate a conveyor , we have limited space for unloading the rock. I would like to know whether some other densephase conveying systems can be used for unloading the rock phosphate from trucks directly.
Cost is another factor in this project.* We can save some money by high heaping* and* our management looks at projects with a high rate of return in the range of* 25-30 % .
Can you advise us on the methods to do the high heaping ?
Finally I thank you for keeping me informed of the latest in Solids handling
Dear Mr Ramakrishnan,
If you have not yet found a solution to your requirement, kindly contact us at email@example.com and visit our website www.scorpioengg.com.
We have handled rock phosphate in dense phase for Deepak Fertilisers.
