Piece type

Frequently asked questions about this model

How long does a concrete piece take to cure?

Between 24 and 48 hours in the dryer, where the heat given off by the piece itself maintains proportional curing without drying it out or cracking it, with no need for extra water. Steam can also be added to speed up the process, though it complicates the plant and pallet maintenance.

How does the vibration system of a Rometa block machine work?

All movements are driven by a high-performance hydraulic unit, and mould vibration (key to concrete compaction) is produced by four counterweighted shafts, moving vertically, unidirectionally and fully synchronised. This system achieves homogeneous compaction that improves the piece's final quality.

How much production capacity does the Rometa 4050 have?

Up to 3,000 units/hour, with 180 kW of installed power. It's the highest-output model in the range, with 4 servomotors and automatic palletising.
