Italy: New concrete batching plant for Fratelli Abagnale

Italian precast producer Fratelli Abagnale has been active as a manufacturer of concrete products and precast concrete elements since the beginning of the 1970s. In the 1990s, production was expanded to include products for the sewerage, road and street furniture sectors. New products were introduced, for example, in the fields of water treatment (rainwater treatment plants, biological and chemical-physical plants for wastewater treatment, light fluid separators, constructed wetlands, plants for water treatment and lifting, oil separators, etc.), hydrology (hydraulic balancing tanks, water reservoirs, tanks for firefighting systems, etc.), cemetery construction (burial niches, family chapels or underground tombs made of precast concrete elements, etc.), and equipment rooms (substations, etc.).

Since 2006, the company has been operating an ultra-modern concrete batching plant from manufacturer MCT Italy at its second production site in Palomonte (SA), which is managed via a sophisticated high-precision remote control system and meets high quality standards in high-tech production processes. The expertise of its design team, which includes in-house hydraulic and structural designers, and reliability in production have enabled the company to obtain qualifications issued by the High Council of Public Works at the Ministry of Infrastructure, ENEL type approvals and UNI EN ISO 9001:2015 quality certification from 2006, and to additionally comply with UNI EN sector standards.

Constant growth of Fratelli Abagnale

The constant growth of Fratelli Abagnale, both in terms of the variety of solutions offered and in terms of market shares, made it necessary to invest in a third production facility, again at the Palomonte site, which is dedicated to the production of precast concrete elements for the water treatment sector.

The proposed solution includes a facility for horizontal aggregate storage comprising four linear storage bins. Loading is carried out, via a receiving hopper with a capacity of 25 m³, by an automatic bucket elevator with a capacity of 100 m³ per hour.

The aggregate weighing system integrated into the bucket conveyor guarantees high precision in aggregate batching even for quantities well below the nominal volume of the mixer, while at the same time reducing wear of the coating and ensuring ease of maintenance.

The MP2250/1500 planetary mixer with planetary gearbox ensures perfect hydration of the cement and homogenizes the cement paste in an extremely short time due to the high speed of the mixing stars, which revolve at 3.2 revolutions for each revolution of the mixing vessel.

The concrete is distributed by means of an AV/1500 overhead tipping bucket, which has been designed for a straight or curved track layout with a curve radius of up to 3 m and is equipped with a tipping system for concrete discharge. Both travel and unloading of the tipping bucket are inverter-controlled to optimize both phases and minimize transport times. Via a WiFi network, the tipping bucket communicates with a mobile chute traveling on the same rail system, which is positioned above the stationary formwork selected for the pouring process in accordance with the production schedule.

Milestone in the precast industry

The design of the system is an excellent example of the perfect integration of the batching plant into the overall factory system, in which a continuous and highly precise exchange of information is ensured by means of shared folders populated with input and output data.

Mr. Abagnale confirms: “MCT has been involved from the beginning, understanding our sometimes-complex technical requirements. The company’s team of experts participated in all of the technical discussions that took place at every stage of the project from design and implementation to test runs, commissioning and full operation.”
