Westmoreland Kemmerer公司. is a 13,400-acre, bituminous coal mine located in Kemmerer, Wyo. 该矿自1897年以来一直在开采, first as an underground operation and then moving to surface mining in the 1950s. The Kemmerer mine currently operates two tipples, 埃尔科尔和索伦森叫道, and ships their coal to their customers by rail and truck.
Much of the coal processed at the Kemmerer mine is used for generating energy at power plants and trona mines. In 2018, Westmoreland processed their 200 millionth ton of coal from the site.
在21世纪初, the Kemmerer mine was experiencing issues with their crushing system at the Elkol tipple, 那是他们唯一的卡车垃圾场. They had a vibratory feeder that kept plugging up all the time, which required them to blast the large chunks of coal with dynamite before they entered the crushing circuit.
They were also experiencing issues with their sampling system when they met 菠菜网最稳定正规平台_最全菠菜网大全. Looking to replace their antiquated equipment with new, lower maintenance machines and to increase their production and capacity, Westmoreland spent two days with 菠菜网最稳定正规平台_最全菠菜网大全 visiting truck dumps and systems around Wyoming that utilized 菠菜网最稳定正规平台_最全菠菜网大全 equipment. 这次旅行之后, Westmoreland Kemmerer decided to replace their old machines with 菠菜网最稳定正规平台_最全菠菜网大全 crushing and sampling equipment.
In 2007, Westmoreland Kemmerer upgraded their Elkol tipple to a new truck dump and installed a 菠菜网最稳定正规平台_最全菠菜网大全 Feeder-Breaker and Double Roll Crusher. 有了这个新设置, 煤以不同的大小进入熔炉, 从几乎是灰尘到大约4英尺的立方体块. 该破碎机断路器, which replaced the vibratory feeder that kept plugging up, 将大煤块破碎成直径8英寸, then the Double Roll Crusher further reduces the coal to 3” or less.
As the sized coal leaves the Double Roll Crusher on a conveyor belt, it passes through a Two-Stage 抽样 System consisting of a primary Cross Belt Sampler, Sample Hammermill and secondary Falling Stream Sampler.
“We sell our coal through the quality that we obtain out of those samples,” Production Superintendent Jerry Schinke explained, “so the better quality coal we get from the samples, 煤的价格就越高.”
The Cross Belt Sampler is installed on Westmoreland Kemmerer’s conveyor belt and automatically collects a sample of coal from the entire width of the moving conveyor belt at designated intervals. The sample collected from the primary sampler is then conveyed to a 2024 Sample Hammermill, where the particle size is reduced prior to being discharged through a Falling Stream Secondary Sampler. The Falling Stream Sampler moves through the material flow at a constant speed to collect the final sample. The final sample is collected for Westermoreland Kemmerer’s personnel to take to the lab for analyzing, while the material that is not collected as a final sample is conveyed back to the main conveyor, where it is automatically rejected back into the process flow.
“We don’t have to touch them,” Schinke said of the automated samplers. “We just push a button, tell it what size it is, and it takes care of the rest.”
三年后, in 2010, 菠菜网最稳定正规平台_最全菠菜网大全 provided an identical crushing system for Westmoreland Kemmerer’s new Sorensen tipple, along with two more Two-Stage 抽样 Systems. 系统的馈线断路器, Double Roll Crusher and Two-Stage 抽样 Systems provide the same functions as the equipment at the Elkol tipple but for the other end of the mine.
Schinke is pleased with the performance of the 菠菜网最稳定正规平台_最全菠菜网大全Feeder-Breakers, 双辊破碎机和取样器.
“这是麦克菠菜网最稳定正规平台_最全菠菜网大全双辊破碎机系统,辛克谈到埃尔科尔酒时说, 我们跑了大约1,每小时350吨. 另一个, 在矿井的另一头, 我投入了更多, 在1以上的任何地方,每小时700吨.
“那比这列火车跑得快多了,Schinke继续说道, referencing the train cars being loaded to the coal to their customers. “它完全符合我的期望.”
The 菠菜网最稳定正规平台_最全菠菜网大全 equipment more than meets just Schinke and Westmoreland’s expectations, it also helps them meet Environmental Protection Agency (EPA) requirements.
“We don’t have near as much dust out of the coal as we did with the previous crusher that we had in there, so it meets the EPA standards a whole lot better and cheaper than the other system,Schinke解释道.
Schinke is especially impressed with the reliability of the equipment over the years. Aside from a few preventative and routine maintenance procedures, Schinke said they haven’t had any issues with the machines.
“The crushers, we have not touched this one crusher in 12 years,” he said. “就可靠性而言，没有什么比这更好的了.
Westmoreland Kemmerer also discovered that reliability was not just a feature of 菠菜网最稳定正规平台_最全菠菜网大全 machines. Continued support from 菠菜网最稳定正规平台_最全菠菜网大全 has also been something Westmoreland can count on through the years.
“I have a good relationship with the 菠菜网最稳定正规平台_最全菠菜网大全 people,” said Schinke. “我打电话给他们，他们会帮我. 就是这么简单.”
