The Betomat – a powerful plant with many options
The plant can be supplied on request with two discharge lines, for rapid truck-mixer filling. The ap-
pearance of the plant can of course also be varied too. There are various forms of loader available for
aggregate storage (belt conveyor, bucket elevator, S-pattern conveyor) and various discharge hoppers
as well. The aggregates are moved by the shortest route to their storage compartments, and the low
number of moving parts helps to guarantee reliable operation and minimum wear for a long period.
Other highly practical options from Liebherr include an automatically lowered extending nozzle (1), a
swivel chute for truck discharge (2) and a swivel collecting hopper (3) to accept water when the mixer
is being cleaned and thus minimize contamination of the plant.
Residual concrete returned to the plant and the water used to clean the truck mixers and the main
mixing plant have to be disposed of reliably and at moderate cost. Liebherr can supply two types of
concrete recycling plant (trough and screw patterns) with capacities between 4 and 22 cu. m/h. Sand
and gravel are washed out and the residual water containing cement trapped as a suspension in an
agitator tank. All these materials can then be re-used in concrete production.
Liebherr’s high-pressure mixer cleaning equipment greatly reduces the effort that would otherwise be
involved in performing this task. At the touch of a button, the mixer with its gate can be cleaned each
evening or before lengthy work breaks; this reduces the time-consuming task of manual cleaning with
a hose to an absolute minimum.
