Dewatering system
As an option, a dewatering system can be installed under the batch-
ing gates. Water from the aggregates is trapped and conducted away
downwards by a channel system.
Two discharge tracks
The version with two discharge tracks is available with either one or
two intensive-action mixers. It permits one truck mixer to be filled and
another driven into position ready for filling. Two gates are always pro-
vided on each intensive-action mixer, so that both mixers can supply
either truck filling point.
Environmental protection
To avoid contamination of the air in the vicinity of the mixing plant with
dust, Betomat plants have positive mixer dust extraction and the ce-
ment silos are fitted with air outlet filters.
Winter operation
Thanks to a precisely coordinated heating system for the plant and the
additive storage facilities, together with heat-retaining paneling, opera-
tion in the winter season can proceed without difficulties.
