Operating principle

The operating principle is based on widely tested milling methods: inside the milling chamber, already equipped in the standard version with a cooling jacket and temperature probe for constant monitoring of the process conditions, a rotor equipped with double profile blades collides repeatedly the substance fed until it is reduced to the size imposed by the calibration screen.

Operating variables

The configurations of the hammer mill allow to better treat the products and make the plant particularly adaptable to the process needs.
The main operating variables are:

The reversibility of the rotor which, thanks to the double hammer-knife profile, allows you to manage the grinding action.The knife profile is generally indicated for a delicate grinding action, the blunt-edged profile (hammer) allows a greater impact and a more "aggressive" reduction in particle size.
Adjustable rotor rotation speed with consequent variation of the peripheral speed of the milling blades.Increasing the rotor speed reduces the angle of approach of a particle with respect to the surface of the screen, allowing only the finest particles to pass while decreasing the rotor speed, the angle of approach increases, allowing the passage of larger particles
Easily interchangeable calibration screen.The calibration screens are available with holes of different diameter, shape and distribution and, for specific process requirements, it can be customized.

Thanks to these features it is possible to ensure perfect reproducibility of the results obtained and extreme versatility of use in order to satisfy the most varied process requirements by the end user.

Versions of the Hammer Mill series TB

The hammer mill of the TB series is available both; in the stand alone version and in a configuration that can be integrated into complete process lines and is able to reach fineness even lower than 100 μm, with flow rates starting from 0.1 kg / h in the version from laboratory up to 2000 kg / h with production models.

It is correct to specify that the particle size and production capacity are variable according to the chemical-physical characteristics of the product as well as its typical breaking lines.

Feeding systems for the Hammer Mills series TB

The TURBINE mill can be supplied complete with devices that allow optimal management of the product loading and unloading phases, such as screw feeder, rotary valves or lobes valves at loading, butterfly or rotary valves at unloading.

It should be emphasized that an accurate dosage is an element of not negligible importance for the purposes of the milling. Overfeeding can cause unpredictable results (For example, product batches with larger particle sizes than desired may occur) For this reason, feeding by means of a screw feeder ensures a precise and controlled speed of advancement of the product, helping minimize waste by eliminating operator variables
This type of feeding is also preferable when a particularly fine milling is required.

Wall mounted configuration in isolator for the treatment of highly active products (HPAPI)

In the pharmaceutical field, the use of highly active ingredients (HPAPI - Highly Potent Active Pharmaceutical Ingredients) is constantly increasing, manufacturers are constantly looking for ways to treat HPAPIs safely and efficiently. With our equipment we do not limit ourselves to ensuring reliability and high performance in the handling of these substances, we have developed a solution to ensure their execution in total safety, by installing the system inside an isolator.

Multi-mill station with interchangeable head; "switchtasking" configuration

The "switchtasking" multi-mill station allows the execution of calibration and grinding activities using integrated technologies within a single system.
The prerogative of this configuration is to alternatively allow the quickly and easily interchange of the head of the conical mill with that of the hammer mill, depending on the process requirements.
This application is ideal for R&D and pilot scale activities and can also be installed within a high containment isolator;

Multi-mill station with interchangeable head; "switchtasking" configuration in isolator

Nuova Guseo offers a design that allows to contain the “switchtasking” technology (i.e. the possibility to alternatively, easily and safely interchange the head of the conical mill with that of the hammer mill) inside an isolator.
The motor unit and the relative controls are installed externally, therefore the process activities and the cleaning operations, thanks to the easy removal of the mill head from the rest of the body, are carried out inside the isolator, using gloves or a half-suit. , reducing any risk of exposure for the operator.

Directive 2014/34 EU (Atex)
