Production and sale of calcium carbonate powder and granules
Ferrari Granulati calcium carbonate is made exclusively by selecting and processing Bianco Carrara rubble, universally known as one of the finest raw materials to obtain extremely pure and white calcium carbonates.
In order to improve the finest materials in nature, we were the first in Italy to install a sophisticated opto-electronic system, which, through high speed cameras and an air nozzle deflecting barrier, selects all the material, before it is input into the grinding process, by removing almost all the impurities present.
The careful selection of raw materials and subsequent cutting-edge and highly automated processes, allow us to ensure an absolutely reliable product, with an unparalleled whiteness.
The micronisation product is carried out using a vertical roller mill, followed by a high-efficiency dynamic classifier: the entire system is constantly controlled by an automated monitoring system, which uses the data provided in real time by an online laser particle size grading machine to adjust the system and obtain the utmost granule size consistency.
The following products are always available:
30 micron d98 - 5 micron d50
50 micron d98 - 10 micron d50
Using a plant designed by us, we can create calcium carbonate with optimized granule sizing, to reduce interparticle spaces.
These new products allow for a significant polymer reduction in the polymer compound sector, and for a significant water/concrete ration, in the conglomerate sector.
carbonato di calcio a curva ottimizzata con testa massima 60 micron
carbonato di calcio a curva ottimizzata con testa massima 150 micron
Products obtained by grinding with primary and secondary hammer mills, to obtain a multifaceted granule shape; the sieving evenness is ensured by using a Parsum particle size grading machineand by a Branscan optical quality check unit.
For Bianco Carrara, apart from traditional granule sizes, we also offer:
0,0 - 0,15 mm
0,1 - 0,4 mm
0,4 - 0,7 mm
0,7 - 1,2 mm
1,2 - 1,8 mm
Our products are mainly used as noble mineral load where whiteness and colour consistency are essential.
Ferrari Granulati srl is specialized in the production of marble granules and calcium carbonate. With such a wide offer of materials/granule sizes/mixtures, our products are utilised in many different sectors, with excellent results: from industry, construction and agriculture to several decorative/artistic applications.
