MATERIALS HANDLING
SMARTER SCREENING
First practical application of an innovative screening solution
The Mobiscreen MSS 802i Evo
S
ince 2021, a smart screen for coarse elements from Kleemann has been processing a large number of different materials in Neumünster,
Germany. Flexibility is required here. Whereas sand and fine-grained material are found in the gravel quarry, the screening of rubble and railway ballast is required in recycling applications. Te plant is even used for the processing of topsoil, which is often highly cohesive. Te Mobiscreen MSS 802i Evo can deal with stone material ranging from very fine to very coarse and with all degrees of contamination and is therefore capable of meeting all challenges.
GRAVEL EXTRACTION CASE STUDY One example is its application in gravel extraction. “Here, we have to deal with a lot of sand and a relatively small proportion of stone. Tis means that the side discharge conveyor for fine grain has a real tough job. Other screening plants would soon reach their limits. Tis is no problem for our new machine,” explains André Krebs, proprietor of Ernst Krebs. It is also an advantage that the screen casing can be adjusted over 20% steeper than

comparable plants. Tis guarantees a great cutting effect for the separation of fine material such as sand and a significantly higher output.
FLEXIBILITY FROM LOADING TO SCREEN CHANGE
Te large feed hopper also contributes to flexibility. Te hopper rear wall and the filling aids can be folded variably so that loading from different heights, from both sides and from the rear is possible. Te screen media change is comparatively easy even in the lower deck because the screen casing can be placed completely in horizontal position. Te screening parameters can be adjusted precisely and
even conversion, for example from three to two final grain sizes, is uncomplicated. Transport from one work site to another is also fast: the discharge conveyors can be folded in – without the disassembly of parts. Tanks to the stepless driving control, the plant can also be moved precisely into position.
FOCUS ON EMPLOYEE SAFETY Te display can be operated intuitively and guarantees safety. With the MSS 802i Evo, all relevant functions can be operated from a safe distance. Te display can also be plugged in at different points on the machine. Te user is therefore always near the function currently being executed. Te difficult operation of levers arranged remotely from the component to be folded is a thing of the past. Operation during set-up and service is also simplified.
The advanced solution processes a variety of materials
USERS BENEFIT FROM PRACTICAL SOLUTIONS “It’s obvious that the R&D team looked exactly at what makes work more effective in practice. Everything is so much quicker, set-up times are shorter and output is higher. Tis pays off at the end of the day,” adds Krebs.
