On snowy winter days throughout the United Kingdom, 爱尔兰, 欧洲甚至美国, roads are being kept clear thanks to salt processed at the Irish Salt 矿业 & Exploration facility in Carrickfergus, Northern 爱尔兰.
The three-square mile Irish Salt complex is on the coast of the Irish Sea, 而盐的加工发生在1个以上,200 feet (365 meters) below ground where a series of drivable tunnels nearly 60 miles (96 km) long winds its way throughout the mine. Here, Irish Salt produces up to a half million tons of salt per year.
“Our knowledge of our customer needs is based on decades of meeting tough demands during some very difficult winters,阿尔文·麦克里诺说, 爱尔兰盐业公司管理人. “And to meet those needs, it is important that we have processing equipment we can rely on.”
挑战
Irish Salt has been a strong believer in 辊破碎机 manufactured by 菠菜网最稳定正规平台_最全菠菜网大全 Corporation since the 1970s. They originally purchased two 双辊破碎机, which for years crushed material to spec and required little maintenance, and added a Triple Roll Crusher to the system in the 1980s.
加工材料, large chunks of salt are transported via haul trucks to a feeder after being blasted from the mine’s interior walls and then to a series of five crushers. The salt runs through the crushers to be processed down to a 6.3毫米菠菜网最稳定正规平台_最全菠菜网大全适合道路使用.
Irish Salt officials say they need to keep their machines running, 尽可能少的停机时间. This can be a challenge due to the intense stress salt can put on machinery. They also need a closed-loop system that can recycle and re-process any oversized product that doesn’t fit the screen sizes for separation. In addition, McCreanor noted that the equipment must be easy to operate.
“The system has got be easy to use and effective,” stated McCreanor. “If it doesn’t work when you push a button, then the rest of it really doesn’t matter.”
几十年来, Irish Salt used their existing 菠菜网最稳定正规平台_最全菠菜网大全 equipment to its full capacity and in 2011 needed to replace the entire set of 菠菜网最稳定正规平台_最全菠菜网大全 crushers. 当时, 菠菜网最稳定正规平台_最全菠菜网大全 engineers worked closely with Irish Salt to design a high-capacity system that could work within a small footprint.
“When it came time to change out our 菠菜网最稳定正规平台_最全菠菜网大全 辊破碎机, we had one request,” McCreanor said. “我们说，‘给我们已经有的东西.’”
解决方案
今天, 二次, tertiary and quaternary levels of crushing are handled by 菠菜网最稳定正规平台_最全菠菜网大全’s Triple Roll Crusher, 接着是三台麦克菠菜网最稳定正规平台_最全菠菜网大全双辊破碎机. The crushers feature heavy-duty fabricated steel frame design, abrasion-resistant steel-plate liners and easy-to-maintain parts. This design has allowed Irish Salt to enjoy decades of productive service from their crushers.
McCreanor said the machines provide a strong return on investment with a low operating cost and by generating minimum fines. Mine Manager Derek Moore also noted that the strong designs stand up to the toughest salt processing applications while being safe and easy to operate.
如果需要的话，两人都很感激, 设备用途广泛, allowing adjustments in roll speeds and gap settings to meet most any application requirements.
结果
The plant operates five days a week and the updated crushers help them produce roughly 500,每年消耗1000吨道路盐.
“The Triple Roll Crusher brings the product down to about 2” (50mm),” said Moore. “Then it goes through the Twin Roller that brings the product down to ¾” (19mm), and then the finishing crushers have a smooth and ribbed drum, 这样就只剩6个了.我们需要3毫米.”
干, condensation-free environment in the mine helps keep the equipment reliable, 摩尔说他很欣赏这一点. He also said the 菠菜网最稳定正规平台_最全菠菜网大全 machines do not require much maintenance.
“它们是一种非常简单的机器，”摩尔说. “在夏天，当我们心情低落的时候, 我们对他们进行检查, 检查一下鼓，看看磨损程度, 但总体来说, 它几乎不需要维护. We have an automatic system in them, and basically there’s one man operating the whole plant here. That’s how simple the system is – you hit the button in the morning to start her up. Then at the end of the shift, you hit the “Stop” button to stop her. She doesn’t normally give you any problems during the day.”
If someone were to seek his advice on investing in a 菠菜网最稳定正规平台_最全菠菜网大全 crusher, 摩尔说:“以我们的经验, 它们很容易组装, and they produce a consistent product in a very small space.”
Moore said that the relationship with 菠菜网最稳定正规平台_最全菠菜网大全 continues to be strong and it has been easy to work together any time he needs something.
“We just make a phone call, and they’ll come back with the correct answer to our issues,” Moore said. “Then it’s only a matter of doing the tweaking as they instruct, 然后工厂又开始运转了.”
McCreanor said that he enjoys the long and productive relationship that Irish Salt has had with 菠菜网最稳定正规平台_最全菠菜网大全, 他说:“我们对麦克菠菜网最稳定正规平台_最全菠菜网大全印象深刻. They’re a family-owned business, like we are, and we think we’re of a like mind.”
