Manfredini and Schianchi, in addition to coal grinding, is developing important experience in sectors where the market requires a technology that can produce materials with fine grain sizes with a range of 50-40 microns such as calcium carbonate.

In recent years Morocco has had strong growth and development in this particular sector having an excellent quality of raw material. Manfredini e Schianchi recently supplied two plants for the complete treatment of calcium carbonate.

The first system was installed at Micromix Sarl- Gruppo Orobrique, a new production company located in the city of Berrechid. The unit is mainly composed of a MOLOMAX 6/190-AIR PIG hammer pre-grinder mill, these mills are equipped with centrifugal fin separators to optimize the percentage of fine material after grinding, driven by a process of great potential, and unload the material directly ready to be bagged and transported to its destination.

Near Casablanca, M&S has installed another very similar unit, we are talking about the factory of a long-standing M&S customer, SARL BROYCHIM. In this case there are two production lines in operation: the first, composed of a MOLOMAX MS4/150, treats calcium carbonate for a production capacity of 15 tons/h and the other, recently installed, was designed to grind, treat , bagging and loading onto trucks, barite with a high percentage of silica for a production potential of 16 tons/h.

The plant line is mainly composed of a SLAMMER Hammer Mill (designed to treat raw materials with a very high percentage of wear) and MOLOMAX MS6/190-AIR. Thanks to the automatic control of the internal depression, the MOLOMAX separates the silica particles inside the raw materials which are discarded and automatically collected at the base of the mill itself.

Urussanga Mineiros

The important Brazilian company UM-Urussanga Mineiros, located in the state of Santa Catarina, already a historic customer of M&S, has recently commissioned a new coal grinding plant from the Brazilian branch which will be added to the one already functioning and always supplied by M&S in 2008 with MOLOMAX MS6/190.

This new supply is essentially equipped with an MS-3/120-AIR Pendulum Mill with process filter and with a drying system via an innovative heat recovery system leaving the coquery ovens.

The plant operates on "Cardiff" type charcoal, with an initial humidity of 10% and has a production of 5,5 tons/h with a 90% separation cut below 40 microns.

With the costs of classic energy sources continuing to grow, the whole world is re-evaluating energy sources that were considered obsolete but which, if properly prepared, can be both economical and low-polluting, such as coal, which we remember, is still used today in all the world in many industrial realities, such as foundries and steel mills.

Alina calcium carbonate

Over the last three years, Manfredini and Schianchi has installed several plants for the production of Calcium Carbonate in Kazakhstan at the important Alina Group, one of the country's largest companies producing raw materials.

The first plant which came into operation a few months ago is the result of commercial agreements signed in 2016.

The plant is located in the city of Karatau and is a grinding and screening plant for the production of approximately 20 tons/h of calcium carbonate and is equipped with MAXI-PIG hammer mills, MOLOMAX MS6/190 and screening system business suit.

The second, much smaller plant, located in the city of Taraz, is equipped with a MOLOMAX MS3/120 Pendulum Mill and produces approximately 10 tons/h of calcium carbonate and calcined gypsum.

The third plant, with an agreement signed between the parties in 2017, is located in the city of Semey, which came into operation at the end of 2018 and is equipped with a MOLOMAX MS6/190 finishing mill complete with a series of three-story batteries from Vagli high MS performance while, as a pre-grinder, there is always the MAXI-PIG. The plant in question produces calcium carbonate and calcite with an estimated flow rate of approximately 18-20 tons/h.

A new commercial agreement was recently signed with the Alina Group which provides for the supply of a "twin" plant to the one currently operating in Semey for the new factory, about to be completed in the city of Aktobe.

Thanks to these profitable and satisfying collaborations with the Alina Group, Manfredini and Schianchi is today confirmed as a leading company in Kazakhstan in the supply of plants for the grinding and screening of calcium carbonate.

Umbeto Manfredini

The Manfredini & Schianchi Group is sorry to announce that on Monday the 5th of 2019, at 22pm, our president and co-founder, Umberto Manfredini, quit. In Sassuolo (MO) on 30 January 26, Umberto Manfredini was a leading figure in the panorama of the Italian ceramic industry and Sassuolo. In 1938, the decision to create his own business and build his own individual mechanical workshop teamed with one well-trained and beautiful woman.

For the first time, as a client of the company Fiat Agri de Modène (currently New Holland), specializing in the manufacture of agricultural machinery, Umberto was appointed as client principal. The meeting, for the suite, of future partner Gianfranco Schianchi, brings a decisive change: it is indeed thanks to the union that is neither MANFREDINI & SCHIANCHI, a company leader specializing in the construction of installations of broyage, of preparation of the premier materials for the ceramic and brique industry, of charbon, of calcium carbonate, of bentonite and one of the world's leading experts in the technology of transformation of the wood.

Here is the chance to meet Umberto Manfredini in a person who knows what to expect from an energetic, combative, dynamic and full of new ideas man. A person capable of understanding the changes in the ceramic industry of the future and, consequently, of understanding its needs.

Fervent partisan of the technology of broying à sec, like the world of ceramics insists on the method of broying for you humid, Umberto was always convinced that in the world, particularly in the countries where the eau is considered as a well priced, the technology of broyage à sec can lead to important development margins. As a matter of fact, Manfredini & Schianchi began to export more than one country from six national frontiers and to pursue new markets and countries in Northern Africa, the Middle East, Iran and so on. South America.

Le Brésil was the one of the countries here, over the course of 30 years, to record incredible croissance performances in which the production of carts according to the old method is concerned. There was an effect on visiting South American men towards the end of the 80s in the ceramic poles of Sao Paulo (Santa Gertrudes, Cordeiropolis, Rio Claro) where Umberto immediately discovered the potential. This is also where the Manfredini and Schianchi founders of Brasil are, one of the greatest Brazilian enterprises here, pendant of the years, a product on the site of the première material broyage installations. Grand entrepreneur, Umberto Manfredini has worked for a long time on the streets of other places in the panorama of Sassuolo.

He was actually the former president of the Sassuolo CNA and advisor for sport and culture of the Sassuolo town in the 70s. 70 and he was one of the co-founders, with Manfredini & Schianchi, of the professional association of ceramic machines, ACIMAC in 80, which was based in Milan at the time. Umberto left his wife Pasquina, his children Alessandro and Andrea and all the personnel of Manfredini & Schianchi a great souvenir of him and his teachers. Pour sa générosité, sa loyauté, son respect et sa force de volinté de toujours croire en ses propres idées de him. « If one chose it juste,… il faut y croire et la développer ! Toujours ! Never let go of difficult premieres, but will continue to fight to preserve his own convictions, know how to make him into this idea ... »

Merci pour ton enseignement, Umberto.



The results obtained from the sec preparation process of the mixtures - with the MS-DryTech broaching technology and the sec Fusion granulation (patented) - confirm that it is possible to obtain the grains in ceramic stoneware and present the same characteristic features that the materials produced with the traditional technology to keep you humid. Another advantage is that the strong reduction in energy and water consumption makes the process ecologically sound, which allows for large economies in the production costs.

The uncontested experience acquired by Manfredini & Schianchi in the domain of the preparation of premium materials allows you to further propose the most appropriate technologies, in the tenant complete with the type of available premium materials and the quality of the ceramic product required . The following results are based on a study carried out at the Manfredini & Schianchi Technologique Centre, in collaboration with the Université de Modène et Reggio Emilia and the ITC (Institut de Technologie Céramique) de Castellón.

The objective of this inquiry is to test the conformity of the blends mixed with MS-DryTech and granules with Fusion in the production of the caractéristiques techniques similar to the cells of stoneware. In this case, the composition of the mixture in the dry mixture is formulated according to the classic criteria for the formulation of ceramic mixtures, there is no further modification in relation to the formulations used for the preparation of your humidity. The quality parameters of the ceramic product obtained from the second blend of ceramic stoneware are verified in comparison with other typical blends of ceramic stoneware obtained by humid and atomized broying.

The study includes the control of the mineral, chemical, morphological and granulometric characteristics and the frittability of the obtained mixtures, as well as the macroscopic characteristics and regulations of the products (lineage, water absorption, mechanical resistance, black heart incidence ). The laboratory tests carried out in the experiment body are the following:

  • Measurements of granulometric distribution of mixed powders
  • Chemical characteristics of blended powders
  • Mineralogical characteristics of mélanges
  • Morphological characteristics of the blended powders after granulation, atomization and press behavior
  • Characteristics of the products (RL, AA) obtained from the powders at the cost of the two technologies
  • Comparison of consumption and economies between the two technologies
  • Comparison of the environmental impact of two technologies.

The results

The diffractometric analysis and the granulometric analysis confirm that there are large differences between the results of the two broyage technologies: the dry and humid residue, for example, is 5% of the environment for a granulometric 44 microns broyage. As concerns the morphology of the powders, the cells obtained with the Fusion granulation are more compact and completely free from air flow inside.

Table 1 compares the behavior of the two granules (a Fusion granule and an atomized granule) here, despite the slightly different morphology, it is practically similar to the level of the granule size and the pressing parameters. The higher density of the Fusion granules confirms a more uniform humidity between the coarsest fractions (> 600 microns) and the finest powder (< 100 microns), which does not compromise the filling parameters of the honeycomb favor a surface of the carreau cru beaucoup plus smooth and homogeneous. No more difference than the level of behavior in the kitchen of the two mixtures (foods with a cycle of 38' at 1210°C).

The tableau 2 fournit de façon détaillée les paramètres techniques qualitatifs des carreaux en grès cérame, format 60x120 cm et épaisseur 10 mm, fabricated starting from a mixture obtained using the MS-DryTech technology and the Fusion granulation, in use of the First-class materials easily available and well-stocked.


The experience that the formulations conçues à sec et granulées par les biases de la technologie Fusion allows de fabriquer des produits aux caractéristiques équivalentes à cells des matériaux céramiques obtenus au moyen de la technologie de humide traditionnelle et de l’atomisation.

In particular, the process developed by Manfredini & Schianchi allows for excellent reactivity, perfect for obtaining stoneware products. If you also find the important item in terms of environmental durability within the two processes (tables 3 and 4 in relation to the consumption of energy and water as well as the emissions produced), it is clear that the process Accordingly, the importance of the process for humid and représente désormais a viable alternative for ceramic fabricators here souhaitent se concentrate on a more durable production.
