A Rotar Cleaner Provides Money Spinner
A Rotar Cleaner bucket helped a Nottingham-based company overcome a 17-year old materials processing problem, converting a tricky and sticky waste into a saleable commodity.
The company produced a huge amount of waste material from its construction and utility work that needed to be processed and recycled as a result. However, because the majority of the geology in the Midlands has an overlaying cover of heavy clay, the processing of groundwork material proved difficult. They said, "We can remove stone and brick from the waste easily enough. We bring in a muncher to deal with rebar. We can screen and trommel the vast majority of the material whilst it is dry. But the moment it gets wet, the trommel blocks up and the screener simply isn't efficient enough to warrant trying to separate the waste,” he says. “As a result it gets stockpiled until it's dry enough to process again. Except it rarely is. As a result we had a yard full of a highly sticky waste product we simply couldn’t separate.”
Help came in the form of a Rotar Cleaner from Worsley Plant, highly suitable for aggregate washing.
It proved so effective that it never left, and after a two week hire, it was purchased outright.
“The Rotar worked through the top layers of the stockpile quickly because it was fairly dry and uncompacted. We removed the top quarter of the stockpile, processed and washed it without problem. After this we had the most sticky mess left, which was more akin to thick mud with stones; a totally useless material that was destined for landfill.”
“But we stuck with the bucket but, because of the high wet fine content, we started to use it in a different way. We took to pre spinning the material before washing. This took out quite a bit of the fines. We then did a prewash, which took out the majority of the mud, before a final clean wash, this was simply to prevent having to constantly empty the skips that were used as the washing bays. The resulting material makes an excellent Type 1 product and we've since discovered that it also makes excellent clean drainage material, which the local farmers love, so we have yet another market for the aggregate."
Whilst the real money-spinner, the clean aggregate can be recovered easily. We've opted for quality over speed and it's paid off,” he concludes.
“We have found the only machine capable of processing such a sticky product. Our operators love it for its ease of use, simple maintenance and the fact that we are stating to get our yard back. It is a brilliant solution to a problem that has plagued this yard for too long.”
A Rotar Cleaner is a rotating screening drum, which separates, mixes and cleans various materials in one continuous motion. With the Rotar Cleaner, a simple physical principal is translated to a useful attachment for the recycling, demolition and earthmoving industries.
A Rotar Cleaner can be installed on wheeled loaders, excavators, backhoe loaders etc. Loading and unloading is easy with the Rotar Cleaner. By means of a hydraulic cover, the drum can be opened and easily used as a standard digging bucket.
During the rotation, the fine’s fall out of the drum and the bigger sizes stay in. By use of various sizes of changeable screens, different effects can be realized. With the rolling effect of the material, which stays in the drum, a cleaning reaction is realized by scouring.
The Rotar Cleaner is available in two models and various sizes – the HPL series and the HEX series.
