Mobile Windsifter Terra Select W 70

The Sifter for Cleaning Light Contaminants from Sieve Overflows

If you are the operator of a composting plant or a biomass treatment plant, then you know just how light weight foreign matter, such as plastic bags, in raw compost or in sieve overflows can make life difficult for you?

But now there is an alternative! The Terra Select W 70 mobile windsifter lets you simply remove unwanted contaminants from your process material.

By wind sifting, the Terra Select W 70 allows plastic foil or bags and other lightweight materials to be separated from compost and biomass. Cleaning is also infinitely adjustable to a high level. The throughput achieved by the windsifter is up to 80 m³ per hour. Contaminants can even be removed from materials that have already been screened, regardless of the screening machine used.

The mobile sifter has its own hopper with integrated metering roller. The hopper ensures maximum flexibility in feeding material. The machine can be loaded (at an angle) using a wheeled loader or fed in series or at an angle by an upstream screening system, according to your requirements. The metering roller then ensures a uniform transfer of the material from the hopper to the inside of the windsifter.

A stone separator can be used in addition to separate rolling materials such as stones or (plastic) bottle caps. Similarly, a magnetic roller can be integrated into the windsifter to enable the separation of magnetic metals.

As with Terra Select star screens and trommel screens, the Terra Select W 70 comes as a flexible mobile machine. As the sifter has road approval and only takes five minutes to set up, you are able to change over the location of operation according to your requirements.

The large control display allows you to monitor and control all the functions of the windsifter. Large inspection hatches to the internal mechanism also make maintenance procedures for the machine easier.

The Terra Select W 70 is the choice of professionals for windsifting. And the homogeneous and marketable quality of the end products you produce will be welcomed by your customers.
