Storage is meant to be of two types: Low-capacity bin storages and High-capacity bulk storage. Unlike bin storages, Bulk storage is storage of (Cement, Clinker, Slag, Limestone, Additives, Gypsum and other industrial materials) in large quantities. Followings are the various types of bulk storage depending on the material to be stored for industrial purpose:

a) Slag Storage:

Slag is metal-separated stony waste material in form of their metal oxides mixed with silicon di-oxides. Industrially, Slag storage is generally done for Metal ore smelting process for serving various useful purpose such as ‘temperature control in Smelting’, ‘removing waste from smelting process’, ‘preventing re-oxidation of molten metal’.

Few facts:

  1. Each year, more than 400 million tonnes of iron and steel slag is produced.
  2. In some countries, up to 80% of the cement contains granulated slag, as it helps to bring down the cost of cement.
  3. According to the Slag Cement Association, 59% of the embodied CO2 emissions can be saved by replacing Portland cement with slag cement in concrete.

Advantages:

  1. In most Countries, Slag Storage is used as energy saving material. Therefore, It mainly helps in reducing heating and cooling cost in industries.
  2. Slag storage is helpful in improving compaction characteristics of cement placement.
  3. Slag Storage under sheds is also helpful in keeping low risk of breakability and maintenance of maximum strength.

b) Additive Storage:

Additives are the organic material added to subject material in order to improve its inherit qualities, performance, efficiency and reduce cost. Industrially, Additive storage covers a wide range of antifoams, organic additives and other performance enhancement additives. Some well-known examples of additives are ‘fly ash’, ‘GGBFS’, and ‘silica fume’.

Few facts:

  1. In the United States, 95% of the masonry cement is made by adding additives to subject material like clinker , cement etc
  2. In some countries, up to 80% of the cement contains granulated slag, as it helps to bring down the cost of cement.

Advantages:

  1. Achieve high sustainability of plant by virtue of ‘less electrical consumptions’ and ‘natural resources preservation’.
  2. Storing Additives like fly ash under shed do not require grinding and mixing, thereby nullify grinding cost to plant.
  3. Some Additives like Sulphites are not only highly oxidant in nature, but also causes clinical effects in sensitive individuals. Cross ventilation quality and prevention from adverse conditions of environment across the Additive storage sheds will eliminate such difficulties.

c) Gypsum Storage:

One of the additives, called Gypsum is fine grained calcium sulphate material industrially used as fertilizer/enhancer in subject material to improve its inherit qualities, performance, efficiency and reduce cost. ‘Calcium sulphate di-hydrate’, ‘alabaster’, ‘plaster of paris’, selenite, rock gypsum, and gypsite are some well known gypsum examples used for gypsum storage.

Few facts:

  1. Being the main ingredient in plaster of Paris (PoP), it is useful in making casts and sculptures.
  2. 90% of Gypsum is very soft that it could be scratch with our fingernail.
  3. Most of the Gypsum often found in the mines of Australia, Mexico, US. Out of these three countries, largest ever gypsum crystals were found in Mexico, weighing 55 ton.

 

Advantages:

  1. Gypsum storage sheds is very effective for prevention and control of fugitive emission.
  2. Less operation and maintenance cost is required.
  3. Prevention from vulnerability caused by adverse environmental conditions.

 

d) Clinker Storage:

Clinker is nodular material formed at sintering stage in cement manufacturing process. In the Cement plant, Clinker is prepared by fusing various clays and limestone with additives by melting them below to the point of liquidation. Most commonly formed Clinkers are ‘silica fume cement clinker’, ’pozzolana cement clinker’, ‘ground granulated blast furnace slag cement clinker’.

Advantages:

  1. Clinker storage has an advantage of no spillage of clinker and no dust pollution. This will not only prevent wastage of resources but also create heath friendly environment.
  2. Clinker storage also help in setting up hot clinker to its favorable temperature before being converted into its grinded form, called as cement.
  3. Clinker has quality of moisture proof. The only thing can harm clinker is Rainfall or heavy thunder-storms, which can be easily prevented by clinker storage sheds.

e) Cement Storage:

Cement is grinded form of clinker. In construction, Cement is used as binder material that combines with water and other ingredients and sets to bind two other materials together. That is why it also called as Hydraulic binder. Various types of cements are pozzolana cement, blast furnace cement, rapid hardening cement, quick-setting cement, acid resistant cement, sulphate resistant cement, high alumina cement, white cement, colored cement.

 

Advantages:

  1. Due to its high water resistant nature of cement, cement storage under sheds are highly non-vulnerable to maintain moisture and water resistance in heavy rainfall areas.
  2. Large scale Cement storage are recommended to maintain temperature as well  as ventilation system, which can be fulfilled under cement storage sheds
  3. To feed power stations continuously, we need efficient loading and unloading of cement, which can be done though Stacker/reclaimer under cement storage sheds.

 

  1. f) Limestone Storage:

Limestone (a composition of calcium carbonate, CaCo3 with other minerals) generally found in most organic sedimentary rocks formed from accumulation of coral, shell, forams etc. In construction Industry, limestone is used as one of the major components in clinker/cement formation. Moreover, In precious Architectural works, limestone is also used neutralize the effect of acidity caused by acid rain .

 

Advantages:

  1. Limestone storage under steel sheds will cost about 40% less as compared to reinforced concrete silos. Therefore helps in overall cost cutting.
  2. Steel used in limestone storage sheds is highly corrosion proof as well as water proof. Therefore operation process will be more reliable, long lasting and anti-corrosion.
  3. Limestone storage under storage shed also provide best protection against adverse weather conditions.
