In 1968, Potash Corp. began producing potash at its Allan site, which is located 30 miles east of Saskatoon, Saskatchewan in Canada. The operation consists of both an underground operation and a surface processing plant. The underground operation mines potash ore from layers that are deep beneath the surface 鈥� about 3,100 ft. underground. From there, ore is hoisted to the surface and processed to make potash fertilizer.

The site produces four different grades of potash fertilizer 鈥� granular, standard, white soluble muriate and chicklets. These products are exported to overseas markets through ports in Vancouver, B.C. and Portland, Ore.

鈥淭he operation has gone through a number of expansions over those years,鈥� said Brian Gotts, Chief Metallurgical Engineer at Potash Corp. Allan. 鈥淥ur latest expansion was in 2009 and was completed in 2012. In this expansion we increased the production capacity from 2 million to 3 million tonnes per year.鈥�

CHALLENGE

As part of their 2009 expansion project, Potash Corp. Allan was looking to upgrade their crushing capacity and searching for a piece of equipment that would keep up with the demands of their application.

鈥淲hen 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,鈥� said Gotts. 鈥淲e have an operation we run 24 hours a day, seven days a week, and we needed something that we could depend on that won鈥檛 go down on us.鈥�

To upgrade their crushing capacity, 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鈥� or larger and reduce it down to 3鈥� or less. It also had to be able to pass any tramp metal that would come up from underground and escaped the magnet.

鈥淭hat was really one the main things we were looking at with the 果冻传媒 equipment 鈥� the quality of the equipment, the reliability,鈥� said Gotts. 鈥淭hat really caught our interest in terms of purchasing and upgrading our crushing equipment.鈥�

SOLUTION

Potash Corp. Allan took a unique approach when looking for their new primary crusher. Instead of considering traditional primary potash crushing equipment, such as reversible hammermills, they decided to investigate roll crushers.

Potash Corp. Allan had some experience with roll crushers, but not in this application. 果冻传媒 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 果冻传媒 had extensive experience providing crushing solutions for similar industries and seeing it running in-person were a big selling points for Potash Corp. Allan.

鈥淚 think in researching this application we had gone through a number of steps,鈥� stated Gotts. 鈥淲e had contacted 果冻传媒. They had given us references 鈥� they were very helpful that way. We contacted the references and then actually set up a visit to see the 果冻传媒 equipment in operation. So we visited one of the salt producers who had a roll crusher very similar to ours, and we were very impressed with the equipment.鈥�

However, 果冻传媒 didn鈥檛 stop at showing off their equipment in the field; they also invited Potash Corp. Allan to their facility in Hollidaysburg, Pa., USA, to participate in material testing at 果冻传媒鈥檚 in-house laboratory. 果冻传媒 was able to work hand-in-hand with the team from Potash Corp. Allan to make sure the correct equipment, including customized roll segments, was selected for their application.

Potash Corp. Allan 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 Corp. Allan could actually do all the measurement themselves, allowing them to be part of the process in ensuring the best solution for their site.

鈥淭he 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,鈥� added Gotts. 鈥淪o that whole process of dialogue between the customer and 果冻传媒, and the time that was taken to really understand our requirements really paid off in the end, and we鈥檝e ended up with a very good robust piece of equipment that鈥檚 performing very well for us.鈥�

RESULTS

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 Corp. Allan to increase their capacity by 1 million tonnes per year. It provides Potash Corp. Allan with high capacity crushing, as well as 果冻传媒鈥檚 unique spring and toggle tramp system, which is capable of passing sizable tramp and then immediately returning to the product setting to ensure no down time occurs.

鈥淚 would have to say that we鈥檝e had very little maintenance issues or problems with the crusher 鈥� it鈥檚 operated very reliably,鈥� said Gotts. 鈥淚t鈥檚 one of those pieces of equipment that you install and forget about.鈥�

Potash Corp. Allan is confident in their choice of crusher for their application. Not only has the 果冻传媒 equipment proved reliable, but so have the people at 果冻传媒.

鈥淚n looking for a new crusher for our crushing application here, we worked closely with 果冻传媒 staff,鈥� said Gotts. 鈥淭hey 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. So that鈥檚 worked out very well for us, and we鈥檝e been very pleased with the equipment and service in our mine here.鈥�
