Construction and demolition projects alike can generate large amounts of unwanted or damaged material that might otherwise be regarded as trash. In the past this excess would normally be deposited into landfills however since the inception of the construction and demolition recycling industry businesses can collect most of this waste and recycle it to become useful materials once more.
Throughout its modern existence the construction and demolition recycling industry has relied primarily on crushing equipment to accomplish its purpose particularly portable crusher plants. By utilizing a portable impactor or portable jaw crusher plant construction and demolition waste like concrete and asphalt can be processed through these machines for reuse in new projects.
For example when concrete waste is generated from a construction or demolition project it can be recycled and reused as gravel for new roads or even new concrete as long as contaminates like trash or wood are removed first. Concrete can also be processed and made into a product called riprap large piles of concrete chunks that are used to protect vulnerable shorelines.
An effective crushing equipment choice for recycling concrete is any portable crusher plant that utilizes an impact crusher like the 1200-25 CC featuring Eagle Crushers UltraMax impactor. An impact crusher is especially useful in processing rebar a common byproduct of concrete construction and demolition jobs. Just as well the plant should be equipped with an inline or cross belt magnet to sort the rebar from the recycled concrete product.
Another common construction and demolition resource is reclaimed asphalt pavement RAP usually collected from road-based projects where existing pavement is being torn up. Reclaimed asphalt is valuable as it can be reused to make new asphalt more efficiently than by using virgin asphalt materials. This is due to the preexisting presence of tar in the reclaimed asphalt which lends itself to a more rapid bonding process.
Savonlinna is the home of Finlands leading bridge demolition company Savonlinnan PR-Urakointi Oy. Processing demolition concrete will be easier now that the company has purchased a noise- and dust-proof Lokotrack174 Urban LT96 jaw crusher.
Jul 29 2019nbsp018332Crushed concrete is made up of asphalt debris from other construction projects that can be reused to create driveways pathways garden beds and more. When any concrete structure road sidewalk or parking lot is demolished that concrete is usually deposited in a landfill.
ldquoThe Lokotrack is at least five times more cost-effective than the crushing bucket we previously used. Depending on the feed the LT96 can crush up to 150ndash250 metric tons per hourrdquo says Marko Blinnikka the Managing Director of PR-Urakointi.
ldquoI must say that the Urban is truly quiet. The sound of crushing does not exceed the sound of the engine and you can talk right next to the machine without raising your voice.nbsp Spraying water at high pressure into the crusherrsquos cavity and main conveyor prevents dust generation.rdquo
The noise- and dust-proof Lokotrack Urban LT96 crushed demolition concrete in Savonlinna at a speed of almost 200 metric tons per hour.
ldquoAs an additional benefit the Lokotrackrsquos magnetic separator removes reinforcing bars from the crushed concrete so that we can use the clean crushed concrete for land filling often at the same siterdquo Blinnikka continues.
PR-Urakointi used its new Lokotrack Urban LT96 for the first time at Aholahti in Savonlinna. Approximately 20000 metric tons of concrete from demolished buildings had been piled up in an industrial area. The pile contained reinforcing steel bars some of them only as thick as your little finger.
After a couple of daysrsquo practice crushing with the new tool was effortless. Tomi Inkinen fed the concrete into the jaw crusher Aulo Nemevalts immediately levelled out the crushed concrete artificial fill and Jori Kettunen monitored the machine in operation.
Tomi Inkinen left Aulo Nemevalts and Jori Kettunen from PR-Urakointi have quickly become professional operators of the Lokotrack crusher.
Metsorsquos IC process control proved to be an excellent tool when getting to grips with the crushing process. The team was already well familiar with the different on-screen buttons after just a couple of days.

May 08 2018nbsp018332Concrete was once routinely trucked to landfills for disposal but recycling has a number of benefits that have made it a more attractive option in this age of greater environmental awareness more environmental laws and the desire to keep construction costs down.
The final result is an extremely sturdy construction and landscaping material. Typically crusher run is available in sizes from 34 to a 200 sieve. Depending on the quarry where it was manufactured the material may be comprised of limestone trap rock granite or a combination of these. Best Uses for Crusher
Attachments allow concrete to be economically recycled on site saving on aggregate trucking and dedicated crushing plants.
Equipment used to process concrete on site typically includes various kinds of crushers whether it be a jaw crusher or a crusher plant or pulverizers hammers and universal processor attachments. Crusher and shaft screener buckets and drum cutters can also be used to accurately size concrete materials. According to MB Crusher crusher buckets reduce hauling fees by crushing the material directly on site for immediate reuse.
Many attachments can be used for processing concrete on a jobsite. The product that is most useful for this process will be determined by the specific task to be accomplished and the jobsite conditions says Rich Elliott product and application specialist Epiroc. Taking down a concrete structure building bridge foundation etc. may require a different attachment than processing concrete that is in a pile.
For example deconstruction of a building bridge or structure will be best suited for a multi-processor or concrete cracking attachment. Yet other contractors may prefer a hydraulic breaker for this task.
No single attachment is the best solution for every job. This is completely dependent on the end use for the concrete says Chad Wood Genesis product development engineer. Are you feeding an on-site crusher or pulverizing concrete to a reusable size
If feeding a crusher a dedicated concrete cracker-style tool will most efficiently get the concrete down to a size that you can feed a crusher or haul off site he points out. If you are processing concrete to a size that is reusable on site then a dedicated pulverizer or linkage pulverizer would be your tool of choice. These tools would downsize the concrete into 3-in. minus if necessary as well as make clean rebar that can be taken directly to a recycling center.
