we are making a feasibilty study for ground calcium carbonate project to be build in saudi arabia.

if any one can provide me with that information i'll be thankfull

best regards

15000 t/y is not economical production rate because you need to get a license from your government for a quarry and for a factory then you must rent or buy a digger , loader ,and at least 2 trucks .. theses are the basic quarry tools , also you needs a geologist and 2 or 3 workers at the quarry .....

for your factory :

you need to determine where is the raw material to build the factory in the same area .

then you must find what is the exact particle size and what is the market needs in that area . i mean what is the characteristics for the product you need to produce.

for the feasibilty study i can help you .

give me a call +20100785234 or +20123331916

Hi,

If you still don't get the key iformation of GCC project development ,pls tell us,and we'll be pleased to offer you relevant key information,and based on which we are looking forward to win-win cooperatin. ■

As mentioned in a previous response, the rate in which you want to grind the calcium carbonate is very low. If you ground 50 weeks out of the year, 5 days a week 8 hours a day, you would only have a rate of 0.5 t/hr. This is not an economically feasible rate.

You should consider purchasing the ground calcium carbonate. However, you may be in an area where this is not possible, then you may not have a choice. I would definitely focus your efforts on purchasing this material locally. It should not be that hard to find. Purchasing all of the equipment, (Dump Hopper, Conveyor Belt, Mill with separator, proccess bag filter, and fan, transport equipment, and a storage bin, with transport equipment out of would be very expensive. You could probably buy ground calcium carbonate at this rate for many years. ■

Unfortunately my initial calculation for a rate was wrong.

15000 t/y / 50 weeks / 40 hours/week = 7.5 t/h.

This could possibly be done in a Raymond bowl mill. You should be able to find a used mill that could operate in this manner, possibly cost effectively, depending on the application. If you would like to discuss further let me know.

If calcium carbonate pile is located near the system, you would only need one loader operator to run it, and obviously you would need routine maintenance.

I assume that the facility is located within an existing manufacturing facility.

If it is you would probably want to locate it near a heat source, because the material will need to be dried. You would need to pull hot air through the mill to do this, getting ground calcium carbonate would require a material handling to and from the mill, and a process fan and dust collector to do this. With the information given, it would be virtually impossible to give you the plant area required.

If you need more information please respond. ■
