Using force takes intelligence

The MAC5 is not only a powerful grinder. The patented rotation system of both burrs makes it possible to achieve any kind of particle size distribution, high hourly flow rates (up to 2 tons/hour), with very low energy consumption, while maintaining low working temperatures without the need for any cooling system.

25 amps at maximum power

Steady temperature

Cutting discs

Heart of steel? More than that!

The cutting discs of the MAC5, as well as those of all Colombini grinders, are the heart of the machine.
Made of sintered tungsten carbide with a 1300 Vickers hardness, they have exceptional wear resistance, up to seven times higher than any tempered steel, and can be resharpened up to 16 times.


Maximum performance
for large productions

The MAC5 is designed for large production runs of all types of coffee, from filter to espresso to Turkish, and work continuously while maintaining consistent performance and quality.

packaging machine

Direct feeding of packaging machines

Thanks to their light weight and small size, and the ability to work in start and stop mode without altering particle size distribution, MAC5 grinders can be installed directly on packaging lines, saving space and making installation easier.


The powerful, flexible, modular grinder

With its high performance and small size, the MAC5 is suitable for both modular systems and direct feeding of any packaging machine.


No-oxigen grinding
with the Degassing system

The MAC5 grinder, with its high hourly capacities, is perfect for feeding any degassing system and in particular the BMM/Colombini Degassing system.


Quick startup
and no waste

Calibrating the machine, which is necessary in case of a new production, is immediate and requires no more than 2-3 kg of coffee.

The MAC5 is therefore perfect for those who frequently change production types.


Easy, reliable,

Colombini grinders are known for their ease of use and can be adjusted even by an inexperienced operator.
Consumption is very low relative to performance; low operating temperatures require no cooling systems; and the densifier, while not essential, is available on request.

The MAC5 requires very little maintenance at a negligible cost. Replacing the grinders is very simple and can be done by a single operator in as little as 15 to 20 minutes.
