2. If the cargo is stowed only in the lower compartment, the lower compartment hatch covers should be secured in the approved manner. 3. If the cargo is stowed in the upper compartment above a tween deck whose covers are not grain- tight, the covers should be made grain-tight using sealing tape, tarpaulins or separation cloths.
Bulk cargo refers to trades where dry cargoes are loaded directly on the holds of the ships. Examples of these cargoes are grain, iron ore, coal, and other related items. Break bulk cargo on the other hand refers to the trades where the cargoes are stowed in unitised forms like bags, pallets, drums, crates, and the like. Ships carrying …

Bulk Direct Reduced Iron DRI (Sponge Iron Ore) Shipping. Sponge Iron Ore: A porous form of iron made from reducing an iron oxide at such low temperatures that melting does not occur; usually derived from the purification process of coal gas. Spent Iron Sponge is liable to heat and to spontaneously ignite, especially if contaminated with oil …
We have built a worldwide reputation for designing bulk materials handling systems which help you get commodities such as coal and iron ore out of the mine and onto vessels more quickly and safely, day in day out.
Dry bulk, liquid bulk, roll-on-roll-off (RORO), and breakbulk terminals have a diversity of terminal designs and functions and a broad range of quay, yard and warehousing equipment.
The majority of incidents where bulk carriers have been lost were when carrying iron ore. In the carriage of iron ore, the following precautions should be taken: Iron ores are heavy cargoes which occupy a small area for a large weight, ie they have a low stowage factor …
On occasion, liquefaction of minerals being transported in bulk carriers can occur when repeated loading, produced by the ocean waves and vessels engine, are transmitted to the cargo in the hold of a bulk carrier (Jonas, 2010).Repeated loading can increase the pore pressures of a material which contains sufficient amounts of fine …
Bulk Iron Ore Concentrates Shipping. Concentrated Ores known as Concentrates are produced in two distinct methods:. Dry Method; Wet Method; Dry method concentrates production involves the crushing of high-grade ore and removing waste material, leaving powdered ore with a low moisture content. During the crushing …
Bulk Iron Ore. Iron Ore is a rock containing iron-rich compounds and forms the basic raw material in the manufacture of steel and iron products.. There are many varieties of iron ore, such as hematite and magnetite, mined throughout the world and shipped, especially in large ships, to industrial regions worldwide in the form oi fines …
Iron ore handling and storage terminals. There are two important iron ore terminals for the storage and transhipment of iron ore in the port of Rotterdam: EMO on the Maasvlakte and EECV in the Europoort. EMO' s dry bulk terminal is the largest terminal for iron ore and coal in Europe. EMO stores and tranships these bulk products for various ...
The various advantages of iron ore pellets are given below. Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the iron ore lumps both in the BF and for DRI production. Pellets have good reducibility since they have high porosity (25 % to 30 …
Cargo Handling Procedure for Bulk Carriers. Bulk carriers are specially designed ships that transport large volumes of unpackaged, bulk cargo, such as coal, grain, iron ore, and other dry commodities. …
Loss on ignition (LOI) in the mineral represents the chemically bonded water which can be removed at high temperatures only. High LOI in iron ore fines has an adverse affect during pellet induration process. High-LOI iron ore fines are required for detailed laboratory pelletization studies and are used in pellet making. The received iron ore is …
This method involves using a mechanical grab to scoop up the bulk cargo, such as coal or iron ore, and load it into the ship's cargo holds. The grab can be operated by an excavator or a dedicated grab ship unloader, depending on the size of the cargo and the equipment available.
By 1850 the mining industry had grown to employ about 12 000 miners producing some 1.5 million tons of coal. However, during the second half of the century the Ruhr mining companies, and the steel making plants upon which they depended, developed exponentially and by 1910 there were more than 400 000 miners producing some 110 …
