Specifically, has anyone modeled or do you have knowledge of facilities where cement is transferred from ship to train? That is my first thought, as I am working on a layout loosely based on the Twin Ports of Duluth and Superior. At least one, and I believe two, of these facilities exist here, I'm curious about where they ship to and how the ship-unloading equipment works. 

There is a large cement distribution facility (now apparently closed) in West Sacramento CA, that could be represented in either N scale or HO scale using the appropriate Walthers Medusa Cement Kit.  A pretty accurate model could be made in N scale using the HO kit . It had an overhead pipe line to deliver product to barges on the Sacramento River.       See this Discussion  http://model-railroad-hobbyist.com/node/12676  and check out Google Maps . 

in Lyons CO has rail service, but www.cemexusa.com website states 5K tons by rail annually. And 515K tons by truck. Note the long, large pipe that moves raw material downhill/across the highway to the plant. Use Mapquest and go East from Lyons on Hwy 36t/Ute Hwy. Can't help you at all with what the various buildings are for, but hope this helps a little anyway

    You can see a facility if you google earth the port of Stockton Ca.  Find highway 5 crossing the  upper end of the port basin then look to the west of the highway about a quarter mile and you'll see a cement ship tied up to the south side of the channel. Inland from it is the pipes, silos, and rail car loading tracks. that same ship has been there every time I've been by for the last few years a victim of the housing bust I guess.  The size of the ship and facility is not much smaller than the key rail related parts of a manufacturing plant as far as modeling goes ......DaveB

The facility in West Sac was switched by the Sacramento Northern. Wasn't but a few short years ago there was a ton of rails still around to be ogled. Since removed to make way for, get this, housing of all things...and parking for the River Cats (minor league baseball, Oakland A's, although they're considering switching their affiliation to the SF Giants.)

00 Limestone Quarry and Crushing PlantThe major raw material for cement production is limestone. The limestone most suitable for cement production must have some ingredients in specified quantities i.e., calcium carbonates, silica, alumina, iron, etc. Typically, cement plant locations are based upon the availability of good quality limestone in the vicinity. The quarrying operations are done by the cement producer using the open cast mining process. Quarrying is done through drilling and subsequently, using heavy earth moving equipment such as bulldozers, payloaders, and dumpers. The quarried raw material is then transported to the cement plant, using mechanical conveying equipment such as ropeways or belt conveyors, or by vehicles like wagons and trucks. The quarried limestone is normally in the form of big boulders, ranging from a few inches to meters in size. These varying sizes of limestone need to be crushed to a size of about 10 mm in order to be prepared for finish-grinding. There are mainly two types of crushers available for this purpose- compression type or impact type crushers. There are many types of compression type crushers such as jaw crusher, gyratory crusher, cone crusher, roll crusher. The impact of technology is used in a hammer crusher/impact crusher. Crushing is done either in two stages or in a single stage. In the two-stage crushing system, a compression type crusher is used in the first stage for raw crushing, followed by impact/hammer crusher in the second stage. In single-stage crushing, an impact-type crusher is used. The selection of the crusher depends mainly on the characteristics of the raw materials. This selection is further guided by the particle-size distribution requirements of the downstream equipment such as raw mills and lastly by financial considerations

The raw material is stored at either the quarry or at the plant. Typically, circular or longitudinal stockpiles are used to store the material. A number of layers are stacked in circular or longitudinal piles and are reclaimed in transverse, cross-sectional slices. The stockpiles consist of separate layers/piles of different kinds of raw material. This is used in segregating the raw material quality-wise. The required quantity of the various raw materials is thus easily extracted for use. The extraction of different qualities of raw material is monitored and controlled in order to maintain the desired composition of raw meal, suitable for feeding into the kiln

In order to get the required composition of raw material, certain additives such as iron ore, bauxite, laterite, quartzite, and fluorspar are added in the required quantities. These additives are stored at the plant in separate hoppers and are extracted using belt conveyors in conjunction with belt-weighing equipment. This ensures that only the required quantities are extracted and added to the raw material

The raw material is finish-ground before being fed into the kiln for clinkering. This grinding is done using either ball mills or vertical roller mills (VRM). The raw material is simultaneously dried. Ball mills use impact with attrition principles for grinding the raw material. Inside the ball mills, various sizes of balls are used and classifying liners are used to maintain the position of different sizes of balls. The larger sized balls are utilized for impact grinding and the smaller balls for attrition. VRM uses the compression principle to grind the raw material. The choice between a ball mill and VRM is governed by many factors such as the moisture content of the raw material, the size of the plant, the abrasiveness of the material, the energy consumption levels, reliability, and finally financial considerations. Ball mills are suitable for low and medium moisture content in the range of five to six percent and are preferred for abrasive material. The main advantage of VRM is higher grinding efficiency and the ability to accept material with higher moisture content. Normally the energy consumption level in VRM is 10 to 20 percent lower than in ball mills

Normally there are various sources of limestone, each with different qualities, which are added with various additives to get the required composition of raw mix. As there are various sources of raw materials, it becomes necessary to blend and homogenize these different materials efficiently to counteract fluctuation in the chemical composition of the raw meal. The variations in the composition of kiln feed have very adverse impacts on the efficiency of the kiln. It results in undesired coating and ring formation inside the kiln. In order to blend and homogenize the raw materials properly, continuous blending silos are used

The most important activity in cement manufacturing is clinkering (or burning) of raw material. Clinkering takes place in the kiln and the preheater system. Preheater systems offer heat transfer from the hot kiln gases

Like industries from aviation to financial services, the cement business has been on a “big is beautiful” march over the past five decades. A rush of expansions, mergers, acquisitions, and consolidations has reshaped the industry. The model has not necessarily created value for companies or their investors. In pursuit of growth, they often overpaid for acquisitions, constrained their balance sheets, and were insufficiently disciplined in capital and operational expenditures. Consequently, the sector has an erratic value-creation history. Recently, however, demand growth has shifted to emerging regions where urbanization has been creating opportunities for regional companies to shine. A promising outcome of these developments has been the emergence of value-creating regional champions.

As for the multiregionals, they have gotten back into the M&A game. Recent consolidations among top players raise important questions. Will value creation continue to be elusive in this new round of consolidation? Can the industry’s largest competitors learn from the experience of the regional companies in creating value through growth? Can big be beautiful beyond the local level? And if it can, what can be learned from successful companies?

Valued at approximately $450 billion,1 1.Based on June 2015 market capitalization of cement companies in a McKinsey sample of 74. the cement industry has shown a mixed financial performance over the past 30 years. Exhibit 1 looks at the industry through three different lenses: total return to shareholders (TRS), return on invested capital (ROIC), and economic profit and industry valuation. The picture that emerges is of a business surprisingly less cyclical than often believed and in which most companies do not deliver returns above the cost of capital

thecement industryat a turning point: a path toward

With the exception of the crisis years of 2008 and 2009, the cement industry has shown strong cumulative returns, as expressed in TRS. Sector performance has been partly cyclical, with the 5-year TRS compound annual growth rate (CAGR) oscillating between 4 and 33 percent at the extremes. However, for 19 of the past 25 years, the oscillation was less volatile, ranging from –5 percent to +10 percent; over the whole period, the sector beat the MSCI market index, with an average TRS CAGR of 11 percent versus 9 percent.

In many industries, TRS performance as a measure of performance is closely linked to ROIC and generation of economic profit. In the cement industry, however, this link is weak. The industry’s record of value creation is spotty, with ROIC levels roughly equal to the cost of capital, at around 9 percent
