Gypsum Handling
Hi Everybody,
Wanted know about Gypsum Handling at port right from unloading from vessel and its storage at stackyard or silo. Which is prefeered way od storage of it either silo or open stack yard? How the dust control is carried out while handling it? Dust Extraction system or dust suppression suystem is used?
Regards,

Gypsum Handling
Hi..
Further to this I wanted know about its storage in silo? We have one requirement of handling Gypsum less than 5 million ton per year. What should be idle storage of it?

Synthetic Gypsum Crushing
About your crusher needs:
The problem is we need more information from you
as far as the available utilities and infrastructure.
Help us to help you help us help you.
The act of crushing or breakage only differ in whether it occurs
for primary breakage to create Run od Mine Ore or secondary/final sizing/grinding.
Its fine to ask, but as you have provided minimal information
about this operation in Canada, we collectively can only
realistically provide a limited amount of information.
You need to provide more detailed information as far as primary handling facilities
and tertiary/secondary processsing.
The year round processing with the Gypsum being stored outside is a huge problem
because of the exposed stockpiles and temperature.
Are you intent bagging or loading the rendered gypsum into covered hopper cars?
If so it is a very very, very, very, poor idea with a stock pile exposed to the
local environment and snow fall.
Any frozen ore loaded in a covered hopper car is going to hold moisture and then as result
be more difficult to unload unless a car vibrator is used.
Anytime a primary or secondary crusher is used it generates heat and creates heat.
The same heat will attract moisture compounding the problems with material stored in an
exposed to the weather.
The other issues are:
1. Any available budget for "ANY SIZE" physical plant used for crushing and sizing .
a. what is the three phase power supply available for a stationary processing facility
b. is a diesel powered mobile processing facility more desireable AS it can be stored
indoors in a heated heated vehicle storage garage.
if B applies a series of mobile conveyors connected trunk to tail(elephant style are
very well used and easliy implemented, as is done at
The Canadian Rock Salt Corporations shallow Mine located at Pugwash, Nova Scotia, Canada.
2. The desired tonnage per hour as it is a chemically rendered byproduct.
a. The Rockwell or Moh's hardness of the rendered Gypsum.
b. The actual screened size if applicable- as the gypsum is powdered when rendered its bit of a moot point.
3. The down stream processing handling machinery which you apparently already have and
which you have decided not to elaborate upon.
Again its fine to ask, but be willing to elaborate much more on this if you want help.
There is no point in telling you what to buy simply because you should be asking this of
Mssrs. George Baker, Lyn Bates, and Lawrence Nordell who are sponsors of the forum.
You can contact any of these fine gentleman via the forum here if you have PM or e-mail priviledges. ■
Gypsum
It all depends on how fast the product is consumed downstream for soil ammendments
and other uses and the machinery and physical plant available to transport it. ■
Crusher For Fgd Synthetic Gypsum
Thank you for your response - I did not find out about your reply until today. In the past, I've had e-mail alerts on response from previous postings.
FGD synthetic gypsum is a by-product of scrubbing SO2 from fuel gas, hence, it is a fairly fine material which normally would not require any crushing. The problem is that the material is dug out from a pond and left to drain for a period of time and then transported to a plant site. It will be stored in an open stockpile exposed to snow in the winter months. From the pile, it will be reclaimed by a front-end loader and metered via a hopper/feeder to process.
The objective of the crusher is to break up frozen lumps of gypsum as well as any rocks/pebbles picked up during handling. Again, Concern is that FGD is also quite cohesive and would tend to plug up any screening mechanism on the outlet of the crusher. An "open bottom" crusher would allow some oversized material to get through - not desirable as we have sensitive equipment downstream.
The problem is we need more information from you
as far as the available utilities and infrastructure.

Crushing FGD Synthetic Gypsum Frozen Lumps
Anyone with experience in using a crusher for frozen lumps of synthetic gypsum? The material is stored outside in a pile, and during winter months (temperature can go down to -50° C), material is likely to be mixed with snow. Small quantity of rocks/pebbles also expected from being stored outside - these needs to be broken down also to minus ”. Concern is that FGD is also quite cohesive and would tend to plug up any screening mechanism on the outlet of the crusher. An "open bottom" crusher would allow some oversized material to get through - not desirable as we have sensitive equipment downstream. ■
