Producing process of ferrous sulfate monohydrate and Iron sulphate heptahydrate

Views:6069     Author:VV     Publish Time: 2016-04-08      Origin:Rech Chemical Co. Ltd

The main raw material of Ferrous sulfate monohydrate is Ferrous sulfate heptahydrate/Copperas, which is light green and blue crystal and is from the Titanium Dioxide factory.

Raw material ferrous sulfate heptahydrate/ iron sulphate heptahydrate is very wet and contains a little waste acid and Titanium, and will corrode metal and cement, but the processed ferrous sulfate hepta contains just a little impurity and has no corrosion, it’s very clean.

 
The manufacturing process of ferrous sulfate monohydrate is very easy, usually, there are two ways, as follows:
 
Method one:
Ferrous Sulfate Heptahydrate (Raw Materials)
Using water for wash in Cleaner
(Wipe Off Surface Impurity)
Filtering
Reactor of Solution
(Heating reactor dissolved materials to re-crystallized)
Centrifuging 
(Wiping off Water)
Drying (Ferrous Sulfate Monohydrate Powder 30-31%)

Packing


The color of ferrous sulfate monohydrate produced with this method is very beautiful and with low content of impurity, but it can only load 20-22MT goods in a 20 feet container. And it makes no granular
Method two:
Ferrous Sulfate Heptahydrate 
(Raw Materials)
Using water for wash in Cleaner
(Wipe Off Surface Impurity)
Rolling Forward in Rolling Kiln
(In Temperature of 380-500 degrees)
(Taking off 6 Crystallization Water Molecule)
(Granulation)
Crushing
Screening
Packing
 
The color of ferrous sulfate produced with this method is not so beautiful as the method one, but it can load 27MT max into a 20 feet container. Finished goods can be shaped as 6-12/12-24/20-40/60-80 mesh


By the way, you can find the method of analysis ferrous sulfate monohydrate in our website.
