Designed to achieve particularly high fineness, this mill offers the possibility to obtain particle sizes even below 5 microns. The working principle does not contemplate the use of grinding bodies, since the reduction takes place exclusively by collision between the particles of product, fed in the grinding chamber through a Venturi injector. The particles are quickly accelerated by a stream of gas (compressed air, nitrogen, argon, or steam) injected by means of nozzles placed at the periphery. These are dragged in a vortical movement that causes them to collide repeatedly, progressively reducing the diameter and mass as long as the energy accumulated by the same drops to negligible values. Micronized particles are carried by the exhausted air into a suitable cyclone filter. At the inner of the cyclone-filter the air is dedusted through a set of filtering bags, in special fabric, and discharged to the outside, while the micronized product is retained on the outer surface of the same. The shaking of the filtering bags is carried out by means of a timed reverse jets of compressed air, which allows the removal of the micronized product that is collected in the bottom hopper of the cyclone-filter, allowing an optimal performance in terms of product recovery. Of simple construction, Micronette series mills are easy to be disassembled without the aid of mechanical tools, to facilitate the cleaning operations and of equally simple use, so that it doesn’t require the intervention of specialized personnel.
The stainless steel version with sanitary type finishes is particularly suitable for the treatment of pharmaceutical products. Furthermore, where necessary, the system can operate in a closed inert cycle (generally with N2) with almost total gas recovery. Integrated configurations within insulator are also available when it is necessary to process highly active products, in addition to systems specially designed for R&D, able to micronize very small batches of product. Of particular interest is the configuration of the cyclone filter fitted with a device for 90° rotation of the filter, which ensures an easy access to the inside of the device in order to facilitate the extraction of the sleeves and the subsequent clean-up of the cone, avoiding the use of ramps or elevators. For particularly active products, sleeves can be extracted through an accessory (supplied separately) consisting of a sight glass provided with gloves, to be installed on top of the filter, ensuring a lower exposure of the operator to dust.

Consulting the website it is possible to view the whole range of products and to appreciate the high constructive quality.
01.FOUNDED IN THE EARLY XX CENTURY
Founded in the early twentieth century by the pioneer Mr Domizio Guseo, the society mainly dealt with equipment for the mining and extraction field. During the years, with the help of new technologies, it has specialized in far more complex areas, such as the chemical and pharmaceutical ones. Thanks to the confidence of old customers who have relied on its skills, Guseo has an undisputed experience which results from a production carried out with great passion. Even today, with the same passion as before, Nuova Guseo follows daily, step by step, those who commit their own work and their own safety to its hands.
Nuova Guseo’s salesperson staff is technically highly qualified and is able to support customers in all technical aspects. The technical department’s staff follows the customer during all the steps of the project up to the commissioning and start-up. Nuova Guseo can supply DQ-FAT-IQ, OQ (SAT) protocols and execution.
Nuova Guseo doesn’t realize series products, but customizes all its equipment according to specific customer requirements. The basic thought is that any new requirement reinforces its knowledge and opens to new challenges.
Nuova Guseo has always considered that customers’ satisfaction is the best reference. For this reason, its aim is to listen to customers’ needs in order to give them the maximum satisfaction from every point of view.
