1968年，加拿大钾肥公司. 开始在其艾伦工厂生产钾肥, 它位于萨斯卡通以东30英里处, 加拿大的萨斯喀彻温省. The operation consists of both an 地下 operation and a surface processing plant. The 地下 operation mines potash ore from layers that are deep beneath the surface – about 3,100 ft. 地下. From there, ore is hoisted to the surface and processed to make potash fertilizer.
The site produces four different grades of potash fertilizer – granular, 标准, 白色可溶性硫酸盐和小鸡. These products are exported to overseas markets through ports in Vancouver, B.C. 俄勒冈州波特兰.
“The operation has gone through a number of expansions over those years,布莱恩·戈茨说, 钾肥公司首席冶金工程师. 艾伦. “我们最近一次扩建是在2009年，2012年完工. In this expansion we increased the production capacity from 2 million to 3 million tonnes per year.”
挑战
作为2009年扩张项目的一部分，加拿大钾肥公司(Potash .. 艾伦 was looking to upgrade their crushing capacity and searching for a piece of equipment that would keep up with the demands of their application.
“When we were looking at purchasing and upgrading our crushing equipment for the plant here, I think we were looking for a piece of equipment that really was reliable and durable,戈茨说。. “我们有一个全天24小时运行的业务, 一周七天, and we needed something that we could depend on that won’t go down on us.”
提升他们的碾压能力, they needed a crusher that would handle up to 1600 tons per hour mill feed, as well as a crusher that would be able to handle ore from the mine that was 12” or larger and reduce it down to 3” or less. It also had to be able to pass any tramp metal that would come up from 地下 and escaped the magnet.
“That was really one the main things we were looking at with the 菠菜网最稳定正规平台_最全菠菜网大全 equipment – the quality of the equipment, 的可靠性,戈茨说。. “That really caught our interest in terms of purchasing and upgrading our crushing equipment.”
解决方案
Potash. 艾伦 took a unique approach when looking for their new primary crusher. Instead of considering traditional primary potash crushing equipment, 如可逆锤磨机, 他们决定研究辊式破碎机.
Potash. 艾伦 had some experience with roll crushers, but not in this application. 菠菜网最稳定正规平台_最全菠菜网大全 tookt hem on a site visit at another customers to see a Black Diamond Double Roll Crusher processing 7 million tonnes of salt a year.
Knowing that 菠菜网最稳定正规平台_最全菠菜网大全 had extensive experience providing crushing solutions for similar industries and seeing it running in-person were a big selling points for Potash. 艾伦.
“I think in researching this application we had gone through a number of steps,” stated Gotts. “我们联系了麦克菠菜网最稳定正规平台_最全菠菜网大全. 他们给了我们推荐信——他们在这方面很有帮助. We contacted the references and then actually set up a visit to see the 菠菜网最稳定正规平台_最全菠菜网大全 equipment in operation. So we visited one of the salt producers who had a roll crusher very similar to ours, 我们对设备印象非常深刻.”
然而, 菠菜网最稳定正规平台_最全菠菜网大全 didn’t stop at showing off their equipment in the field; they also invited Potash. 艾伦来到他们在宾夕法尼亚州霍利迪斯堡的工厂., USA, to participate in material testing at 菠菜网最稳定正规平台_最全菠菜网大全’s in-house laboratory. 菠菜网最稳定正规平台_最全菠菜网大全 was able to work hand-in-hand with the team from Potash. 艾伦确保正确的设备, 包括定制轧辊段, 被他们的申请选中了吗.
Potash. 艾伦 sent three 55 gallon barrels of potash and spent three days in the lab in Pennsylvania doing the testing. The company was able to set it up so that the team from Potash. 艾伦可以自己做所有的测量, allowing them to be part of the process in ensuring the best solution for their site.
“The testing showed that the equipment could do what we needed it to do, and I think that really helped us confirm that we were picking the right piece of equipment for our application here,戈茨补充道。. “So that whole process of dialogue between the customer and 菠菜网最稳定正规平台_最全菠菜网大全, and the time that was taken to really understand our requirements really paid off in the end, and we’ve ended up with a very good robust piece of equipment that’s performing very well for us.”
结果
The crusher arrived on site in 2011 and has been in continual use since that time. It has been operating successfully as a primary crusher and has allowed Potash. 艾伦计划将其产能每年提高100万吨. 加拿大钾肥公司. 艾伦具有高破碎能力, 以及麦克菠菜网最稳定正规平台_最全菠菜网大全独特的弹簧和切换流浪汉系统, which is capable of passing sizable tramp and then immediately returning to the product setting to ensure no down time occurs.
“I would have to say that we’ve had very little maintenance issues or problems with the crusher – it’s operated very reliably,戈茨说。. “It’s one of those pieces of equipment that you install and forget about.”
Potash. 艾伦 is confident in their choice of crusher for their application. Not only has the 菠菜网最稳定正规平台_最全菠菜网大全 equipment proved reliable, but so have the people at 菠菜网最稳定正规平台_最全菠菜网大全.
“In looking for a new crusher for our crushing application here, 我们与菠菜网最稳定正规平台_最全菠菜网大全的员工密切合作,戈茨说。. “They were very helpful in looking at our application and working with us to make sure we got the right piece of equipment for our application. 这对我们来说很好, and we’ve been very pleased with the equipment and service in our mine here.”
