Prefeed Mixer System

Piggyback Hopper Systems are available for Twin Shaft Mixers (MAO/S)

Due to the particular reinforced structure of the tank, Sicoma Twin Shaft Mixers can be provided with a Batch Feeding System piggy-backed on the mixer using the fixing plates on the tank frame without the need of any additional metal structures.

This system is composed by a supporting frame having  the fixing plates that are preassembled at the factory, holding various hoppers.

• Aggregates Holding Hopper with butterfly discharge valve operated by an hydraulic cylinder connected to the hydraulic power pack of the mixer with an additional electrovalve.  The hopper is equipped with an electrical vibrator 270 watt.
• Cement Weigh Hopper suspended on three load cells (compression type), with sliding valve and related pneumatic cylinder to be connected to the air circuit of the batching plant, with fluidisation nozzles, with the coupling flange for an optional electrical vibrator, with the hole for the installation of a WAM Hopper Jet filter.
• Water Scale suspended on three load cells (compression type), with butterfly discharge valve and related pneumatic cylinder to be connected to the air circuit of the batching plant.

 Top Cover with a connection flange for the Air Bag(s).

We strongly recommend to use the Air Bag(s) as the discharge of the Aggregate Holding Hoper is very fast.  All electrical devices (load cells, micro switches) are cabled and connected to a IP55 Junction Box fixed to the hopper frame.

(*) Volumetric Theoretical Capacity depending on the size of the mixer.
