Processing Pulverized Ground Calcium Carbonate
Sir - There are many flow and material build up problems which can occur when processing and storing such fine material The key areas where such problems occur are:
Bins & Hoppers - side wall build up (ratholing) and bridging.
Baghouse Filters - choking of filter bag material resulting in poor bag life and reduced filter performance, plus hopper pluggage.
ID Fans - build up on impeller, causing fan unbalance
Ducting - internal buils up leading to blockage
These are just a few of the many area of plant within which problems can occur, however these problems are easilly cured by the installation of a suitable model of acoustic cleaner mounted in the correct position. Acoustic Cleaners produce sonic sound waves which make the particles both debond from each other and also from the surface to which they are attached - thus both eliminating and preventing material build up and facilitating material flow. If you are unfarmilar with Primasonics Acoustic Cleaning Technologies (also know as Sonic Horns) please take a look at our web sites:

href="http://www.sonic-horns.com" target="blank">www.sonic-horns.com
Both contain specific sections on all these different applications and we have solves material build up and flow problems in a wide range of different process and storage plants in over 45 countries world wide.
We provide a variety of questionnaires and the following link will lead you to these Questionnaire in both on-line and PDF formats

Finally I attach a photograph of a typical Primasonic Acoustic Cleaner mounted on a filter hopper.
We will be pleased to offer whatever help and advice you might require. Finally, India is by far our largest overseas market and so you can contact a large number of our clients and/or visit their plants.

Pulverizing Calcium Carbonate
You may have to use jet mill for such fine grinding. A grinding mill with a capacity of ~4 Tonnes per hour is available. Get more details from this website: grinding.http://www.jetpul.com/mequip/prs.htm
Normally such fine powders will have more specifications like colour (whiteness index), impurities etc. Limestone as mined may not be an ideal raw material unless you are getting raw material from a good marble deposit.

Re: Processing Pulverized Ground Calcium Carbonate
Hi,
From a study that I have begun in course of an assignment to design and set up a GCC plant overseas, it seems quite clear to me that one should start with (a) the right raw material that will result in a white and bright product , and (b) optimise the crushing and grinding sequence such that the overall energy cost is low. A variety of fine grinding or milling equipment are available all over the world, with every equipment having its own strength. A right combination of such equipments should lead to manufacturing the product GCC at the lowest cost. ■
Processing Pulverized Ground Calcium Carbonate
Processing units for 100 MTPD Pulverized Ground Calcium Carbonate
Dear Sir,
We, as a multinational group, have diversified our business in various lines of work such as Textiles, Entertainment (Multiplex theatres) and Infrastructural development (Real Estate and Construction) under many names. Now we are stepping into Mining and Mineral Processing business. After conducting an appropriate work-out, we are eyeing on field that is very fresh for us. We are considering putting up a plant to pulverize the Ground Calcium Carbonate (GCC).
As per our knowledge, fine ground Calcium Carbonate is in use as fillers in plastics, paints and in paper. Paper filling and coating is produced normally on wet milling stages whereas, all other applications are produced on dry process. In the market, fine ground calcium carbonate is available in various sizes, up to 20 microns. But, our aim is to go further in advance stage and pulverize the calcium carbonate up to 2 microns or less than that. Further, we would like to install the production capacity of 100 MT per day (24 hr operation).
Due to qualitative and economical aspects worldwide, several types of classifiers are used in combination with the ball mill systems. However we have no other information available to us regarding the processing method to pulverize Ground Calcium carbonate. Auxiliary, we do not know the specification and outlays of Plant & Machinery. Therefore, considering your in-depth experience in pulverized units, you are requested to forward us appropriate information with quotations of the pulverized units.
Your help will be much appreciated. So along, we gratefully welcome you in order to expand Marvelore in India, as well as globally.
Many Thanks with best regards!
