Coal terminal queues reach record highs

Filed under: Uncategorized — Tags: — sbmzhcn @ 8:03 am

Ships queuing for Australian coal ports have reached an all time high of 223, costing millions in exports.

Bottlenecks at Australian coal port terminals, in particular cyclone affected Dalrymple Bay and Hay Point in Queensland, have created queues of up to two months.

The congestion, which has seen 103 ships waiting for access to Darymple and Hay point alone, is expected to cost Australia eight million tonnes of coal exports and millions of dollars.

The bottlenecks across the east coast come despite upgrades to a number of terminals as well as the first shipments from a third coal point terminal at Newcastle.

Coal infrastructure has already shown signs of strain since late last year after an unexpected increase in Chinese demand tested the struggling infrastructure.

According to reports from The Australian, port congestion in the country is already at levels three times higher than China.

First trainload of Hunter Valley coal arrives at NCIG

Filed under: Uncategorized — Tags: — sbmzhcn @ 7:35 am

The first trainload of Hunter Valley coal for export arrived at the recently opened third coal terminal at the Port of Newcastle yesterday, NSW Ports Minister Paul McLeay announced.

The new terminal is the showpiece of a plan by the Newcastle Coal Infrastructure Group (NCIG), which includes BHP Billiton, to ease the congestion at the Port of Newcastle.

“In January, the NSW Government brought the Hunter Valley Coal Chain Agreement into effect, providing industry with certainty and security,” McLeay said.

“From this NCIG and its shareholders committed over $1 billion to increase the capacity of the Hunter’s coal export chain.

“The building of Stage One of this terminal has made a notable contribution to the regional and state economy.

“When it reaches full capacity of 30 million tonnes a year the value of New South Wales exports will rise by $3 billion.”

According to the State’s Minister for the Hunter Jodi McKay, the increased capacity at the NCIG terminal was great news for the region.

“Up to 800 people have been working at NCIG each day thanks to the recent expansion,” she said.

“These jobs are great news for families in the Hunter and the flow-on effect they have to the region’s economy is very welcome.”

NCIG general manager Paul Beale said the process of commissioning the massive and complex terminal will take some time.

“Over the past three weeks NCIG has received 12 trains or 80,000 tonnes of ‘sacrificial’ coal,” he said.

Metal Ore Mining Industry

Filed under: mining equipment — Tags: , , — sbmzhcn @ 2:31 am

The metal ore mining industry segment covers the extraction of metal ores such as iron, gold, silver, lead, and copper. Many kind of this mineral have a different of industrial purposes. copper is the main element of electrical wiring, lead is used in batteries, iron is used to get steel, gold and silver are mainly used in jewelry and high-end electronics, and zinc is used to coat iron and steel to reduce corrosion and as an alloy in the having of bronze and brass.
Most metals do not exist in concentrated form but rather in little traces in rock. Indistinguishable from natural rocks to the untrained eye, some ores are presently mined that contain only a fragment of a percent of metal. As a result, a massive amount of rock must be extracted from the ground in order to obtain a useful amount of metal. As a effect of this, and because metal ores are less common than coal, metal mines can be much larger than coal mines and control in more extreme environments while coal mines are rarely more than a few hundred feet underground, gold mines can be over a mile below the surface.
A important amount of processing is necessary to change ore into usable metal. The mining industry includes initial mineral processing and planning activities that are located together with mines as part of the extraction process. Further processing is classified under the main metal manufacturing industry.

coal crushing plant

Coal is a readily combustible black or brownish-black sedimentary rock normally occurring in rock strata in layers or veins called coal beds. Coal has very wide using fields in our daily life. SBM crushers and Grinding mills are neccssary equipments in coal processing.

Coal

Coal is a readily combustible black or brownish-black sedimentary rock normally occurring in rock strata in layers or veins called coal beds. The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure. Coal is composed primarily of carbon along with variable quantities of other elements, chiefly sulphur, hydrogen, oxygen and nitrogen.

Coal Uses

  • Coal as fuel
  • Coking and use of coke
  • Ethanol production
  • Gasification
  • Liquefaction
  • Industrial processes
  • Cultural usage
  • Coal as a traded commodity

Coal Crushing Plant

In order to use coal more rationally, efficiently and effectively, the coal need to be processed and crushed into different sizes, 0 ~ 25 mm particle size for coal gas stove, 25 ~ 8 mm for steam locomotive, 25 ~ 6 mm for the industrial furnace, and coal power plant requires grain coal of 0 ~ 25mm. So coal processing includes coal crushing and coal grinding. Coal crushing plant consist of many types of crushers and Grinding mills. Coal crushers including primary Jaw crusher, secondary Impact crusher and Cone crusher etc. Coal mill include Ball mill, Raymond mill, Vertical mill etc.

Coal Crushing and Grinding Process

If the coal block is bigger than the mill’s max input size, it must be crushed before grinding. The crushing plant common includes Vibrating feeder as feeding material to Jaw crusher, which is as primary Jaw crusher. If need secondary crusher, Cone crusher or Impact crusher can be used. After primary crushing, the coal can be feeding to Ball mill to fine grinding. To increase Ball mill effective, the vertical coal mill or coarse powder mill can be setted before Ball mill as pre-grinding.
