Our 3-fraction starscreen can also be used as a screening and mixing machine with the appropriate equipment. The wheel, crawler or wheel-crawler tracked machine can then be used to stabilise soil with lime, cement or other aggregates. The drive is diesel-hydraulic.
The coarse screen separates larger particles and loosens up the fine fraction. The fine fraction falls onto a conveyor belt and is then weighed and mixed with the compound from the attached binder container during transfer. At the transfer point, the mixture is additionally mixed by a hammer roller and remaining agglomerates of the soil are beaten smaller. The screened soil mixed with compound is transferred at a height of 2.8 metres by the side discharge conveyor.
The binder container is equipped with a dust extraction system, filter, level indicator and overpressure control. The filters are cleaned one after another by compressed air. The machine is controlled by CANBUS and the program. With the appropriate compound, a relatively dust-free and exact mixing with up to 200 tons per hour is possible.
