The machines handle large stones. With a drum of 1.2 – 1.8 meters in diameter.
Retrieve values
Stone can be separated from all types of mass. Soil, roots, shingle, clay that sticks can be dumped into the sieve.
Tested in Norway
Norsk Stein and Stangeland Pukk have MDS machines which they use to clean masses.
Fines are separated
Fine material can be used on site, to build up slopes, flower beds and the like.
Easy to move
Pack up transporters and drive it up on the trolley within the hour.
Stangeland recycles with a drum sieve
When Stangeland Pukk created industrial land for Norsk Hydro on Karmøy, they used the MDS drum screen to separate rock from the excavated masses.
They sifted out a fraction which they used to break up the plot, and a smaller one to build up flowerbeds and surrounding areas, before putting in soil. As much as possible was used on site.
They save money on:
Relax buying in so much material
Avoided many tons of landfill
Did not pay for shipping from and to
MDS 412
300 tonnes per hour
MDS’s drum screen can be used to dig out of land, utilize excess stock in crushing plants, when building ditches, road construction, and separating sticky masses, e.g. clay from stone.
Simple but effective technology knocks off all loose material.
Environmentally friendly and profitable
With a drum screen for stone, you save money because you don’t have to bring in so much stone from outside, and it is also beneficial for the environment to reuse masses on site. This way you avoid transport stages both to and from. If you extract so much rock that you cannot sell it all directly on site, you can sell it on.
If you run a landfill, you can first charge for the masses. You can then use a drum screen to extract stone from the same mass, and then sell it on again. You earn both in and out. The goal is to throw away as little material as possible, while making money.
Drum sieves are supplied in various sizes, depending on what you are going to produce and the quantity. They can also be combined and lined up if needed for several factions in the same place.
