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 saddened to announce that on Sunday 05 May 2019, at 22,30 pm, our President and founding partner, Umberto Manfredini, passed away.

Umberto Manfredini was born in Sassuolo (MO) on 26 January 1938. He was a leading figure in the panorama of the Sassuolo and Italian ceramic industry.

In 1960 he decided to start his own business and built an individual mechanical workshop equipped with only a cutter and a lot of good will. At the beginning, instead of working for customers in the ceramic district, Umberto's main client was Fiat Agri of Modena (now New Holland) specialized in the manufacturing of agricultural machinery.

The subsequent meeting with the future partner Gianfranco Schianchi gave the decisive turning point: in fact in 1962, thanks to the union between the two, MANFREDINI & SCHIANCHI was born, today a leading company specialized in the construction of grinding systems, preparation of raw materials for the ceramic and brick industry, coal, calcium carbonate, bentonite as well as being one of the main companies in the world providing technology for salt processing.

Those who were lucky enough to know Umberto Manfredini in person know that he was an energetic, combative figure, always dynamic and full of new ideas. A person who had the ability to foresee the changes in the ceramic industry of the future and, consequently, understand its needs.

Strong supporter of dry grinding technology, even when the ceramic world was insistently moving towards the wet method, Umberto has always pushed and believed that in the world, especially in those countries where water is considered a precious commodity, technology if dry it could have significant margins for development. This in fact was the case, especially when Manfredini & Schianchi began to export more and more outside national borders and to penetrate new markets and countries such as North Africa, the Middle East, Iran and above all South America.

Brazil has been one of the countries that in the last 30 years has marked incredible growth performances of tiles produced with the dry method, in fact, Umberto visited the South American giant towards the end of the 80s in the ceramic district of Sao Paulo (Santa Gertrudes, Cordeiropolis , Rio Claro), immediately understood its potential. In this way he founded Manfredini e Schianchi do Brasil in that period, which for years was one of the largest Brazilian companies, locally producing raw material grinding systems.

In addition to being a great entrepreneur, Umberto Manfredini, in his 81 years of life, has held numerous other positions in the panorama of Sassuolo life, in fact he was both president of the CNA of Sassuolo and Councilor for Sport and Culture of the Municipality of Sassuolo in the 70s, he he also had various roles within Sassuolo Calcio between the 70s, 80s and 90s and was one of the founding members together with Manfredini & Schianchi of the trade association of ceramic machinery, ACIMAC in 1989, which at that time had its headquarters in Milan.

Umberto left his wife Pasquina, his sons Alessandro and Andrea and all the staff of Manfredini & Schianchi with a great memory of himself and his teachings.

For his generosity, loyalty, respect and willpower to always believe in his own ideas.

“If something is right,… it's right to believe in it and carry it forward! Always ! Never give up when faced with the first difficulties, but continue to fight to keep your beliefs intact, your faith in that idea..."

Thanks for your teaching Umberto.



The results achieved by the dry body preparation process - with MS-DryTech grinding technology and subsequent Fusion dry granulation (patented) - confirm that it is possible to obtain glazed porcelain stoneware tiles with the same characteristics as materials produced with traditional technology wet.

With the double advantage that the strong reduction in energy and water consumption makes the process decidedly "green", allowing great savings on production costs. The undisputed experience gained by Manfredini & Schianchi in the sector of dry preparation of raw materials today allows us to propose the most suitable technologies, taking into consideration the type of raw materials available and the quality of the ceramic product required.

Below are the results of a study conducted at the Manfredini & Schianchi Technology Center, in collaboration with the University of Modena and Reggio Emilia and with the ITC (Institute of Ceramic Technology) of Castellon. The objective of the investigation was to test the suitability of mixtures ground with MS-DryTech and granulated with Fusion in the production of tiles with technical characteristics similar to porcelain stoneware.

For this purpose, the composition of the body to be ground dry was formulated following the classic criteria of the formulation of ceramic bodies, i.e. without making any changes compared to the formulations used for wet preparation. The qualitative parameters of the ceramic product obtained with dry ground mixtures were then verified, comparing them with those of a typical porcelain stoneware mixture obtained with wet and atomised grinding. The study involved the verification of the mineralogical, chemical, morphological and granulometric characteristics and the sinterability of the mixtures obtained, as well as the macroscopic and regulatory characteristics of the products (linear shrinkage, water absorption, mechanical resistance, incidence of black core). The following laboratory tests were performed in the experimentation:

  • Measurements of particle size distribution of mixture dust;
  • Chemical characterization of mixture powders;
  • Mineralogical characterization of the mixtures;
  • Morphological characterization of the mixture powders after granulation and atomization and relative behavior in the press;
  • Terracotta characteristics (RL, AA) of the products obtained from the powders with the two different technologies;
  • Comparison of consumption and savings between the two technologies;
  • Comparison of the environmental impact between the two technologies.

The results

Both the difractometric and granulometric analyzes confirmed that there are no substantial differences between the results of the two grinding technologies: to make a comparison between the two technologies, the residue both dry and wet is approximately 5% of the granulometry of grinding of 44 microns. As regards the morphology of the powders, the one obtained with the Fusion granulation was more compact and completely free of air voids inside it. Table 1 compares the behavior of the two granulates (a Fusion granulate and an atomized ) which, despite the slightly different morphology, were practically similar in grain size and pressing parameters.

The slightly higher mold density in the Fusion granulate confirms a much more uniform humidity between the larger fractions (>600 microns) and the finer powder (<100 microns), which does not compromise the filling parameters of the alveolus, favoring instead a green tile surface that is much smoother and more homogeneous.

The analysis of the firing behavior of the two bodies (fired with a 38' cycle at 1210 °C) also showed no differences. In detail, table 2 reports the qualitative technical parameters of porcelain stoneware tiles measuring 60x120 cm and thickness 10 mm, manufactured with a mixture made with the MS-DryTech process and Fusion granulation, using easily available and low-cost raw materials.


The experimentation carried out has shown how the formulations designed dry and granulated with Fusion technology allow the manufacture of products with characteristics equivalent to those of ceramic materials obtained with the traditional wet grinding and subsequent atomization technology.

In particular, the process developed by Manfredini & Schianchi allows excellent reactivity, perfect for obtaining porcelain stoneware materials.

If we add to this the large gap in terms of environmental sustainability between the two processes (tables 3 and 4 compare the energy and water consumption and the emissions produced), it is clear that the dry process is a winner compared to the wet one , now representing a valid alternative for ceramic producers who want to focus on increasingly eco-sustainable production.
