New Acland 煤炭 Mine, a part of the New Hope Group, began production in October 2002. Since that time, they have expanded their operation and production to the current point of 4.每年800万吨.
New Acland is unique from other Australian mines in that it is all drive-in and drive-out, 许多员工都住在当地社区. A lot of the people who work at the mine transferred from another mine in Ipswich, but many are also local farmers who continue to farm with the support of their wages from the mine.
新阿克兰的煤来自于所谓的细煤层矿, so that material mined in some seams can be as small as 100 mm or as large as 2 m. Many of the 2 m seams have a number of smaller coal seams combined into one, 也就是说他们之间有很多次分手. Those partings are high in clay or even rock, which can make coal very difficult to process.
除去粘土和其它的分离物, New Acland needs to add a lot of water when the coal goes through the crushing stage. 这可能会给设备带来许多问题.
“The resource is very difficult to process and one of the major problems is the clay that’s in the coal and having to add water at the crushing stage, 这对海豹造成了很大的伤害, 轴承的早期故障和高维护成本, 低可靠性, 还有工厂可用性的问题,罗布·拉什利说, 纽阿克兰煤矿的厂长.
In 2009, the site began an upgrade to their wash plant and realized that their existing tertiary sizer was creating a bottleneck in potentially increasing production through the plant. It was during this expansion that they began to look for alternatives to their existing sizers that would remove the bottleneck, 以及解决密封和轴承的问题.
New Acland also kept in mind that they would need a sizer to handle their very hard coal. The site is different from others in the coal industry in that their final product size is 38 mm, 而大多数都是50毫米. To make sure the hard coal is properly sized takes more energy and wear resistance from a crusher.
“When we first started to look at that upgrade we looked at a couple of different companies that could meet our requirements, 特别是轴承的布置, 的片段, and also we wanted to make sure we didn’t increase the fines in the coal as well,拉什利说. “So we looked at a couple of different companies through that stage and were introduced to 菠菜网最稳定正规平台_最全菠菜网大全.”
Since 菠菜网最稳定正规平台_最全菠菜网大全 Corporation provides custom engineered process solutions, 它并没有为新阿克兰提出一个放之四海而皆准的解决方案. 而不是, 菠菜网最稳定正规平台_最全菠菜网大全 worked to combine elements from several designs to provide a special Tertiary DDC-Sizer to process the coal. 这种特殊尺寸包括舷外轴承, as well as stud welded segments and faster rotational gearboxes.
“One of the biggest things we realized with 菠菜网最稳定正规平台_最全菠菜网大全 was when we first talked to them that they were happy to change a design to suit our needs rather than giving us an off-the-shelf product,拉什利说. “They actually modified from a couple different bits of equipment that they had to come up with a design that was ours so it was unique to us, 他们在整个阶段都与我们合作.”
The 菠菜网最稳定正规平台_最全菠菜网大全 Tertiary DDC-Sizer has proved to be the solution that New Acland needed. 事实上, 事实证明它非常成功，在第一次安装之后, the mine site switched out their existing sizers for 菠菜网最稳定正规平台_最全菠菜网大全 ones, 包括两个二级ddc浆纱机和两个三级ddc浆纱机.
Additionally, the design of the DDC-单独 reduced the maintenance costs.
“我们遇到的最大问题之一是维护成本. 我们拥有的其他机器维护成本非常高. 我们不断地更换轴承密封件. In the first year with the initial tertiary sizer from 菠菜网最稳定正规平台_最全菠菜网大全 that we put in, 我们的维护成本为零,拉什利说.
In addition to eliminating maintenance costs with the improved outboard bearing design, 菠菜网最稳定正规平台_最全菠菜网大全’s specially designed carbide impregnated teeth on the Secondary DDC-单独 have drastically increased the wear life of 的片段, allowing New Acland to process 5 million tons of product without having to change segments.
These improvements and reduced maintenance requirements have led to both wash plants being able to run 8,1万小时. This was something they had never been able to do before purchasing 菠菜网最稳定正规平台_最全菠菜网大全 DDC-单独, because every six to 12 weeks they needed to replace bearings or perform other maintenance tasks. They are now able to rely on their sizers to keep production going.
“One of the biggest issues for us here is reliability of the wash plant – our resource is very difficult,拉什利说. “我们今年的平均产量可能达到50%. We need to run the plants for long periods to get the product tons that we need. To have equipment in there that’s reliable and that we can count on allows us to get those production hours.”
Rashleigh also said that it’s not just the equipment from 菠菜网最稳定正规平台_最全菠菜网大全 that he appreciates, 还有公司与New Acland建立的关系.
“菠菜网最稳定正规平台_最全菠菜网大全的整个车队都很好相处. 这些家伙经常在打电话, 看看事情进展如何, but when you really realize you’ve got a great team is when Mike 菠菜网最稳定正规平台_最全菠菜网大全 himself, 当他访问澳大利亚时, 来到矿区和我们坐在一起聊天,他说.
随着新阿克兰煤矿展望未来, 他们正在寻求将产量增加到7辆.每年500万吨. An expansion of this size would bring more jobs to the area through the construction phase, 以及由于容量增加而增加的运营工作. 他们知道要想扩张成功, they’ll need more than good equipment – they’ll need a partner who will help them get there.
“与麦克菠菜网最稳定正规平台_最全菠菜网大全合作是一个非常好的过程. 我现在认为这是一种合作关系. They’re not just a supplier to us, they’re working with us to solve these problems. 设备非常好，”拉什利说.展望未来, 我不认为矿业会回到过去的水平, 所以有麦克菠菜网最稳定正规平台_最全菠菜网大全这样的合作伙伴真的很重要.”
