CLINKER STORAGE SYSTEM

We were discussing “Cements and its types” and “Clinker cooling system in cement industries” in our previous posts. We have also seen the concept of “Cement kiln firing system” and “Cement kiln refractory lining” in our recent post.

Today we are going to start here one very important topic i.e. clinker storage in cement industries. We will understand the various terminologies and engineering concepts used in cement technology with the help of this category.

Further we will go for discussion of clinker grinding, cement packing and dispatch, pollution control and much more facts about cement technology in our next post in this category of cement technology.

Clinker storage

Clinker after cooling in the clinker cooler, is transported by metallic conveyors and stored either in open or covered areas for aging which improves the grinding efficiency in the subsequent operation in the cement mills and increases the mill output rate. The aging of clinker is commonly done for a period not less than 20 days.

It is a fairly common practice to store cement clinker in outdoor stockpile or in roofed but not completely enclosed building. The dust nuisance associated with such open storage is accepted as something to put up with.

The recommended storage capacity to be provided corresponds to between 15 and 30 days production.

The various types of storage yards used are

1. Longitudinal stockpile with side scraper or portal scraper

2. Circular stockpile with semi - portal scraper

3. Silo of steel fabricated or RCC type

The circular stores are widely used now days, even though they cannot be expanded in future for increased capacity, because of the following reasons

1. Investment cost for civil work is least. It is also cheaper than silos

2. Minimum dust nuisance

3. No dead zones, giving optimum utilization of space

Do you have any suggestions? Please write in comment box.

We will see other topic i.e. “Clinker grinding unit process” in our next post in the category of Steel and cement technology.

I am very thankful to Mr. Subrata Bhaumik, Independent cement consultant, for providing such beautiful information and contents about cement technology.

Mr. Subrata Bhaumik has more than 50 (Fifty) Years (1965 - 2016) of Experience in Cement and other related Industry covering more than 100 assignments in cement plants with capacities ranging from 100 tpd to 10,000 tpd in India and abroad involving visit to 25 countries overseas in connection with work.
