muslimska dejtingsajter gratis 12 years on: record-breaking cement unloader still going strong

dejtingsajter flashback skvaller In 2005, the Houston Cement Company LP enlisted Siwertell’s expertise in bulk material handling to provide a solution capable of meeting such high-capacity unloading demands that it required setting a new industry standard.
att dejta en militär “The heavy-duty unloader was, and still is, extremely well-suited to meet the terminal’s high annual throughput needs,” says Peter Göransson, Siwertell Sales Manager. “The low cost of maintenance and its low energy consumption has further added to its suitability.”
bra dejting sajt recept At the time, an unloading rate of 800t/h; introduced by Siwertell in the 1980s, was regarded by the cement market as an informal industry standard for mechanical ship unloaders. To handle the 1.5 million metric tons of cement, which is imported and distributed by the terminal each year, Houston Cement required an unloading solution capable of delivering a discharge rate which far exceeded this standard.

Nothing else compared
vilka dejtingsajter är seriösa Freight and demurrage rate turbulence in 2005 meant that Houston Cement Company sought a solution to increase the terminal’s import capacity. It was initially in contact with other providers, but the Siwertell unit’s unrivalled unloading rates, high through-ship performance and low environmental impact secured the investment.
fakta om dejtingsajter “Prior to delivery of the unloader, the terminal was maxed out at about 1,000,000 metric tons/year and was very difficult to manage logistically due to the size of our ships, the size of the storage domes and the numerous suppliers we were utilizing at that time. We needed increased throughput and increased storage options,” explained Jim Gatens, President of Houston Cement Company, when he reflected on the Siwertell installation in 2018.
kristen dejtingsajt badoo “Although we previously consulted with other manufacturers for information on their unloaders, no other unit could provide the high capacity rates we were looking for. We were also already familiar with Siwertell machines, which helped fuel our decision to invest,” he added.
A concrete investment
dejtingsajt 50 plus jobs Looking back at Houston Cement’s unloading operations, Mr Gatens said the terminal has functioned as advertised and has performed very well. “It has done everything that we hoped it would.

nätdejting profilbild gmail When it was commissioned, the terminal was considered state-of-the-art; asked if it still warranted this description, Mr Gatens replied: “I think it does.”
He said that the terminal has proved to be cost-effective and worthy of the additional investment in the Siwertell high capacity unloader and it had regularly exceeded its projected discharge rates. “It can comfortably handle cement with varying characteristics,” he said. “Upon initial start-up of the Siwertell unit, it was discovered that the machine would unload well over the 1,500t/h mark. The entire machine itself had to be cut back by about 20 percent as it could easily discharge at over 2,000t/h and more.

By using the speed setting on the inlet device, it is possible for the terminal personnel to compensate for the different cements while still achieving a desirable unloading rate. The Siwertell unit itself is also designed to unload the cement at a consistent rate by varying the speed on the inlet device depending on the amp load of the vertical conveyor. This, for the most part works well, but there have been times when we have seen momentary spikes well over 2,300t/h.”

erfarenhet av dejtingsajter gratis In 2014, Houston Cement Company took the decision to update the computers, software and computer system wiring.

Applicable pages can be printed out to aid maintenance.

SIMON monitors equipment hours, which lets operators know when maintenance is due. It is also capable of identifying fault locations in the electrical switch gear, as well as the monitoring of all motor amps and important data.”
Service contract ensures long-term performance

“With regard to the small amount of problems we have had over the years, Siwertell experts have provided swift assistance. Their field representatives are all extremely knowledgeable and competent,” he said.

He will always answer any questions that we may have and assists us if in the area. The electrical engineer is also very well-versed with the onboard electrical systems and, as with the mechanical engineer, will always respond in a timely manner if we encounter a problem. The support of these two Siwertell representatives has been excellent.”
Standing the test of time

The fully-enclosed trolley is connected to the feeding conveyor and moved along the shore conveyor by the ship unloader. It is equipped with a set of wheels travelling on a rail profile attached to the shore conveyor.

The movable transfer trolley design includes versions for screw or belt conveyor receiving systems,” Mr Göransson notes.
And for the future?
nätdejting frågor quiz According to the US Geological Survey (USGS), shipments of Portland and blended cement experienced a 2.4 percent year-on-year growth rate to reach 95.5 million metric tons in 2017, up from 93.3 million metric tons in 2016. Increases of over five percent were seen in Arizona and New Mexico, Kansas, Missouri, Texas and Washington.
dejtingsidor som inte kostar pengar direkt Houston Cement is also noticing this pick-up in the market, which is why it took the decision in 2018 to add a fourth truck-loading point to increase capacity in this area. “The limiting factor for the terminal was how many trucks could be loaded, not how fast it could unload a vessel.
spid dejting u beogradu “We are confident that the ship unloader is more than capable to handle future increases,” said Mr Gatens. “If we were considering a similar new terminal today, probably the most significant change would be the addition of more truck loading bays. We have discovered that it is much easier and faster to put the cement in than to get it out. Also, seeing as the cement can be moved well at the 1,500t/h speed, we could possibly consider going to an even higher unloading rate.”
