I have a Komplet 5030 screener and a Komplet 7040 mobile crusher that I purchased as demo units. The 5030 scalper type screener allows me to screen soils as well as aggregates. The 7040 allows me to add recycled concrete to my list of services that I have by going green and recycling busted slabs instead of burying at a landfill. These machines have been reliable and the parts and support that I receive from the distributor has been very good. Being able to diversify and add services in unstable times is key to being successful and having a good supporting distributor is a must.
