Floor Plan

Among the different milling systems known at present, the jet mill is undoubtedly the most suitable for the micronizing of chemical and pharmaceutical products.

Thanks to its very well established and particular working principle it is able to meet numerous demands of fineness until to obtain, without the help of moving and classifying parts, micronized particles typically 100% below 5 µm, granting the total absence of metallic part pollution.

This is a result that cannot be achieved by more conventional mills, having different conception.

The jet mills are the ideal solution for formulation and development of agrochemicals, fungicides, insecticides, fertilizers, pigments, polymers, plastics, metals, cosmetics, chemicals, foodstuffs, drugs, etc… heat-sensitive products, abrasive and explosives can be micronized without causing damage to product or to jet mill and in absolute safety conditions.

The “Sanitary Version”, stainless steel construction, is particularly suitable and widely used for grinding materials having pharmaceutical use. The jet mills can work, if necessary, in closed circuit (usually with N2 gas with almost total recovery of the gas). Upon request are also available configurations integrated within isolator whenever necessary highly active process product, as well as systems designed specifically for R & D, able to micronize very small batches of product.

An important innovation is represented by the TILTBAR CYCLONE FILTER, it is a high efficiency gas-solid separation filter, with a special device to 90° rotation. This arrangement greatly facilitates the extraction of the sleeves and cleaning activities, without the aid of access ramps and lifting devices, in addition, for products which are extremely active, it is provided a special manipulator which protects the operator from the contact with the treated substance during sleeves disassembly.

“CUSTOMIZED” SOLID HANDLING
Thanks to the experience gained over more than 70 years, Nuova Guseo has developed a deep process knowledge in various areas of application such as chemical, pharmaceutical, nutraceutical and cosmetic, for which is also in a position to realize both stand-alone systems and complete process lines, completed with a wide range of accessories.

What does it mean customized solid handling?
Nuova Guseo’s mission is the "customer service", in the broadest sense of the term, our proposals are in fact developed and implemented on the basis of specific needs and our growth derives from an ongoing dialogue with the end user in order to grant him a full and effective support.

Among our products:

glove boxes, designed and manufactured in strict compliance with the requirements of safety and ergonomics, configured for different applications and containment levels, granting a high protection level respectively:

for the operator;
for the processed product;
for the environment.

mixers, to homogenous blending of powders and powders with liquids, are realized in vertical and horizontal version. Vertical mixer can be used in vacuum and pressurized processes.

hammer mills, able to reduce to powder a variety of substances having different granulometric sizes (spices, sugars, cereals, dry and not vegetables, minerals, chemical and pharmaceutical compounds).
If required, considering particular characteristics of product (fat content, toughness, sensitivity to temperature), these mills can be configured in order to be suitable to run at cryogenic temperature;

cone mills, ideal to obtain a uniform size of the particles for substances with starting inhomogeneous particle size distribution;

jet mills, available for both R&D and production, purposely designed to meet extreme fineness requirements, these mills offer the possibility to obtain particles typically below 5 microns;

screw conveyor, one of the most simple and practical means for transport of solid material. This is an extremely versatile device that allows its use in the most different industrial sectors such as mining, chemical, foodstuff and pharmaceutical;

weighing and bag filling units, simple as reliable equipment, consisting basically of a tank or hopper, of a transport system (screw or vibrating) and of a weighing unit, whose control is acting directly on the extracting screw, modulating the screw speed in order to obtain the fast approaching to the selected weight.
