Valtorta AND Battaggion Group: Professionals in the mixing field

Valtorta Battaggion Group S.r.l. started its business in 1926 under the name of Valtorta Costruzioni Meccaniche. After having experienced different fields, Valtorta focused its business on the development and the manufacturing of mixing equipment, as well as process plants for the chemical industry. The continuous development of the plastic materials led Valtorta to a deeper specialization in all those plastic related processes, with the consequent expansion of its own production range. Starting out from the first Horizontal Blenders, the company quickly moved into high-speed turbo-mixers for PVC, making of technical development and construction quality its motto and growing as a company capable of satisfying and anticipating the market technological needs. Sturdiness, high production efficiency, easiness in operating and flexibility in meeting each Customer’s needs, have always been the peculiar characteristics of our work philosophy.
With the aim of a technical, commercial and production range increase, in 2010 Valtorta joined the Battaggion Group, a well-known and established organization which has been active in the mixing world for more than 100 years. Main focus of its machinery is the processing of high to very high viscosity products.
Within the Battaggion Group, Valtorta has then become the specialized division in the production of machinery for powders and granules, as well as for all liquid and pasty products, characterized by low to medium viscosity. The combination of the two companies has therefore boosted the already wide product range of the Battaggion Group, granting a deeper market penetration in the mixing technology.

Valtorta is nowadays in the position to provide turbo-mixing plants for PVC production, single coolers, feeding and dosing lines (both mechanical and pneumatic type ), dispersers and vertical mixers for solutions (plastisol, PU, varnishes, paints, etc.), horizontal mixers (single or two-stages type both cooled and heated), homogenizing and filtration units, conical mixers for powder, high speed horizontal mixers, as well as special plants. During the last decades the company built a great experience not only in the manufacturing of stand- alone machines but in their integration into complete production plants too. More and more the same customers which require Valtorta machines for mixing processes, also require that these same machines become one of the many sections which compose their production line. This means that most of the Valtorta machines need to be interfaced with upstream feeding systems, as well as with downstream systems for the
movement of the mixed product. It is in this stage that all the experiences and the synergies allowed by the different companies which compose the Battaggion Group can make the difference. The deep knowledge of the materials to be processed, their initial and final properties as well as the customers’ final expected results are essential for us to grant complete systems which must be able to integrate today’s state of the art of the mixing technology. It is with this spirit that during the whole course of management of a complete plant project, an open and professional exchange of opinions with our customers becomes the basis for the Valtorta’s and the Battaggion Group’s technical staff to head towards a feasibility study first and towards the design, the construction, the installation and the successful start-up.

The ME mixers are the Valtorta horizontal slow speed mixers, to be used mainly for those processes which require a not aggressive slow mixing action: they can provide a high quality of the compound, even when the product to be processed is fragile or it must keep unchanged specific physical characteristics. Main applications are the mixing of TPR, PVC, powders or dry granules but, if necessary, also powders and low viscosity pastes, added with liquid components.
In 2002 Valtorta manufactured the biggest ME ever assembled in the facility: the 30.000 liters bowl horizontal slow speed mixer. The project was challenging, but Valtorta demonstrated to be capable of accomplishing the final task, as always, which is to supply high performance plants. At the time the customer purchased two of these machines at once.
The two ME 30.000 were designed to homogenise granules or powders in the petrochemical industry.
Each one of the two machines had a thermally conditioned, 30.000 liters bowl made of stainless steel and the action of a continuous ribbon blender driven by a 110 kW electrical motor granted high mixing performances. The discharge of the mixed product was done by a pneumatically driven shutter valve installed on the bottom of the bowl. The huge dimensions of these machines did not stop Valtorta from jumping into this project.

The TSOR are the most efficient combination of machines for the PVC mixing and preparation for the extrusion line. The output rhythm is the highest of all these various systems, this choice demands that the manufacturing materials and equipment should be the best and most suitable to the customers’ needs. In 2020 Valtorta manufactured a 2.000 liters TS with 6.000 liters OR: the biggest TSOR ever assembled by the company. Made by stainless steel AISI 304 and driven by 450 and 75 Kw motors, this plant was purchased by the customer for rigid PVC.
The 4 impellers installed inside the Turbomixer bowl and the Cooler Horizontal high speed mixing shaft with paddles profiled blades, ensure the best homogenization of the product. Valtorta is always ready for new challenging and exciting projects. Be the next one!
