Backers pipeline padder
Backers Maschinenbau GmbH is a German company and manufactures 2- and 3- fraction starscreens. An advantage of the Backers starscreens is that they can screen wet material with a fine screening size. This is important when there are worse conditions regarding weather or material for example with loamy soil.
The Backers pipeline padder is the starscreen 2-ta which is build on tracks and it screens into 2 fractions. The fine material, which is padding the pipe, gets out sidewise of the machine. So the Backers pipeline padder can drive along the ditch of the pipe. Also it’s possible for the pipeline padder to screen at hilly terrains up to 10 degree.
The capacity of the pipeline padder depends on the material, screening size, percentage of oversize, terrain etc. At 20 mm screening the capacity can be up to 200 tons per hour, at 15 mm it’s up to 150 tons per hour. The finest size which the Backers starscreen can screen is 5 mm.
On top of the hopper can be a grizzly mounted. It covers the starscreen against bigger stones and other oversizes.
The starscreen 2-ta can be used for pipeline padding but also to screen other mineralical material like building rubble or organical material like compost, wood chips etc..
For better transport of the starscreen 2-ta the measurements had been optimized in 2012. Now the measurements for transport are 12.00 x 2.55 x 3.30 m (l x w x h).
