Rometa Accessories for Precast Concrete Production Lines

The operator sets the dose for each colour from the plant control cabin. A 50-litre weighing cart with three load cells travels under each pigment hopper and receives the set quantity through an electromagnetic feeder. When dosing is complete, it moves to the aggregate belt or skip and discharges the pigment there.

It lets you produce pieces with two types of aggregate: a coarser one underneath and a finer or pigmented one on the visible face, cutting colourant cost by up to 70% since the whole piece doesn't need colouring. Machine output drops by 25% compared with standard mode, since filling happens twice (two mixes), but the pigment savings offset that capacity loss on decorative pieces.

Precise, consistent colour reproduction on every cycle, thanks to automatic pigment agitation and a cleaning system that minimises production stoppages. It's compatible with Rometa's aggregate, additive, cement and concrete dosing systems, and allows colour-gradient effects.

They sit between the mould and the vibrating table and transmit vibration to the piece with maximum efficiency. Rometa recommends wood or synthetic-material pallets for correct manufacturing and production of precast pieces.

Up to 40%, thanks to precise temperature and humidity control during curing before palletising, which also ensures uniform mechanical strength. They fully integrate into continuous production lines for blocks, pavers and other pieces.

It is supplied in sets of one, two, three or four colours, with an airtight 0.5 m³ hopper for each pigment. Weighing is done in a 50-litre cart fitted with three load cells.

The hoppers are airtight, the electromagnetic feeder discharges through an enclosed chute, and the 80 × 80 mm outlet has a pneumatic closure that keeps it shut while the unit is idle.
