案例研究
挑战
At MCC’s busiest limestone quarry in Mackville, Wis., they crush and wash manufactured sand for use in their blacktop and concrete plants.
“多年来, we never had any way of drying our product up,” said MCC Washed Materials Production Manager Terry Ross. “It was getting costly sending wet material to our asphalt plants. 它需要更多的石油和燃料. We decided we had to dry it off because of our demand.”
As well as needing a drier product, MCC wanted a plant that would give them the ability to quickly and easily move their production from one location to another.”
“All of our plants are portable,” explained Ory Green, Aggregate Production Manager at MCC. “We go from about 17 different pits and quarries to do all of our washing and crushing, 可移植性是关键. Being able to tear down and move in a number of days and have that uptime is very key.”
罗斯补充说, “Most of the benefit for the company is you can go to the job, to the location where the material is. 如果你是静止的, 你得做很多卡车运输, a lot of expense hauling material into the plants at all times. 如果你是便携的, you can go to the material and put up what you need in that area at any given moment.”
解决方案
MCC has had a long relationship with Aring Equipment and Supply, 菠菜网最稳定正规平台_最全菠菜网大全’s aggregate equipment dealer in Wisconsin, and they looked to them for a solution. 通过撕咬, MCC purchased a 菠菜网最稳定正规平台_最全菠菜网大全 UltraDRY VD18 脱水 Screen to dewater material discharged from their twin 44” wash plant.
“With the production yield that we gained on that and the moisture content dropping, we decided to go with another VD 18 on our twin 36,格林说. “Again, Aring was very helpful in getting us the equipment that we need to get our job done.”
The skid-mounted UltraDRY screens can be installed under any brand of screw washer, and they fit easily under MCC’s existing sand screws. Designed with flexibility in mind, the 菠菜网最稳定正规平台_最全菠菜网大全 UltraDRY can be quickly and easily torn down and moved to a new location with one pick when required.
With the highest g-forces in the industry, the 菠菜网最稳定正规平台_最全菠菜网大全 UltraDRY removes the most moisture to yield a drip-free product for easier material handling. Featuring a 菠菜网最稳定正规平台_最全菠菜网大全 Slurry Pump and sump, the UltraDRY screen returns a portion of the water removed from the sand product back to the screw washer for reuse in the washing and classification process.
结果
The UltraDRY 脱水 Screen provides MCC with the flexibility they require to operate at optimum efficiency. When MCC needs to move their wash plant, they know they can be up and running in the new location in a matter of days. 
“在洗涤厂一般, depending on the size of the setup, we will be looking at anywhere from about four to seven days for teardown, mobilization and setup to be up and running in the next spot,格林分享道. “Having the VD18 on the skid has made it very portable and very user friendly for getting it set up with minimal downtime.”
Green said the addition of the 菠菜网最稳定正规平台_最全菠菜网大全 UltraDRY 脱水 Screen after their existing wash plant has resulted in a “tremendous yield increase” for the company.
“It’s all about the finished product,” Green said. “We’ve gone from a moisture content of 18%, and with the UltraDRY screen we’ve dropped that down to about 7-8% moisture content.”
The 菠菜网最稳定正规平台_最全菠菜网大全 UltraDRY allows MCC to create a drier manufactured sand that they can use in their blacktop plant, saving them money on oil and fuel.
“It saved us a lot of money,” Ross explained. “We can put a product on the ground and in two days be hauling it up to our asphalt plant, running it through and saving us a ton of money.”
In addition to saving money by creating a drier product, MCC has seen improvement in their stockpiles after using the 菠菜网最稳定正规平台_最全菠菜网大全 UltraDRY.
“We get less segregation, better uniformity in our piles; they stack better. We make less mess under our conveyors, less cleanup. It helps all the way around to save money,” said Ross.
