A ready mix company in Michigan that was looking to supply its own aggregates for its ready mix facility recently purchased a quarry with the goal of setting up a sand processing plant there. The company wanted to produce clean concrete and mason sand as well as clean coarse aggregate.
挑战
One of the company’s main concerns was lignite contamination in its sand products. Lignite can create pop-outs, deformations and discoloration in concrete products, so it is imperative that as much of the lignite be removed from the sand as possible.
Another challenge was the variation in feed material for which the company’s processing plant needed to be able to adjust.
“Drastic swings in feed gradations can wreak havoc on process equipment, and you can have issues with producing a consistent product,” said 菠菜网最稳定正规平台_最全菠菜网大全 Regional Sales Manager Matthew Lear.
解决方案
Through 菠菜网最稳定正规平台_最全菠菜网大全’s Michigan dealer, HiPoint Aggregate Equipment LLC, the company sought out a solution from 菠菜网最稳定正规平台_最全菠菜网大全.
“菠菜网最稳定正规平台_最全菠菜网大全 has a very long history of processing experience,李尔王说. “They knew that we have a lot of experience in the field working with sand and coarse aggregate products.”
In order for 菠菜网最稳定正规平台_最全菠菜网大全 to design the right solution for the company’s unique application, the company shipped samples of their feed material to 菠菜网最稳定正规平台_最全菠菜网大全’s Applications and 研究 Laboratory in Hollidaysburg, Pa. 进行分析. Based on those gradations, 菠菜网最稳定正规平台_最全菠菜网大全 partnered with HiPoint to provide the company with a full turnkey system to produce clean coarse aggregate and clean, 在说明里 sand products — a concrete sand and a mason sand product. The processing plant includes a Horizontal Sizing Screen, 日志垫圈, 冲洗屏幕, Lites-Out™ Flat Bottom Classifier, Sand-Manager® Sand 分类 Tank, Pumps and two UltraSAND Plant dewatering circuits.
“What led them to the purchase was really our turnkey capability with HiPoint and 菠菜网最稳定正规平台_最全菠菜网大全 working as a team to design the system, supply the equipment, supply the structure and all the piping, and also to install and commission the system,李尔王说. “We helped them as a partner to make sure they were successful in producing clean products at the end of the day.”
结果
Each component of the plant was specifically chosen to help the company reach their goals of clean, 在说明里 sand and clean coarse aggregate while accommodating for varying feeds with the use of a Sand Manager Sand 分类 Tank. On the aggregate side, a 菠菜网最稳定正规平台_最全菠菜网大全 日志垫圈 was able to remove the toughest clays to discharge clean coarse material. On the sand side, 菠菜网最稳定正规平台_最全菠菜网大全’s Lites-Out™ Flat Bottom Classifier is designed to separate and remove lignite from feed material to produce an ASTM, 在说明里 sand product. The sand is then pumped to a 菠菜网最稳定正规平台_最全菠菜网大全 Sand 分类 Tank, which is great at producing clean, 在说明里 products no matter what gradation it is fed. The sand is then discharged to the UltraSAND Plants to dewater the material and recover fines for a drip-free material without product loss.
“It’s a very intricate system where a lot of pieces are working together,” Lear explained. “They had to be designed and sized properly to operate at their most efficient point.”
The main benefit of this 菠菜网最稳定正规平台_最全菠菜网大全 plant is its ability to handle multiple feed gradations and produce two clean, 在说明里, sand products at the same time, which it has been doing very efficiently since startup.
“Overall, it’s been running really well,” Lear shared. “They’re getting clean coarse aggregate and clean concrete sand and mason sand.”
