Briquetting presses

Briquetting presses are machines for pressing wood waste and scraps and therefore useful for the disposal and recycling of manufacturing waste.

For many years our expertise in design, research and construction have made our "OL.D" range of hydraulic presses the ultimate in efficiency and reliability.

Pelleting plants

With more than 25 years of experience, Costruzioni Nazzareno has become a leader throughout Europe in the design and construction of “turnkey” systems for processing industrial waste.  

A plant or system is a group of machines joined together for the production cycle. This cycle differs in every plant, since the characteristics of the product to be processed (type of wood, particle size, moisture content, initial state, etc.) are always different. The system may be divided up into sections that may be automated according to customer requirements or requests; in other words we can supply a fully automated plant or automate just single sections.

We design and build belt and rotary drum dryers. These machines are developed only after we have meticulously analyzed a wide range of operating and stress conditions in the field, thereby ensuring the range is sturdy and reliable. Our dryers can efficiently process large quantities of raw materials while guaranteeing that the final product respects customer requirements.

"K" slow-rotor shredders have been designed to shred any type of wood, i.e. reduce the volume of bulky wood waste.

The result, in terms of wood chip size, varies according to the result and use that must be achieved.

Once refined, the shredded material free from plastics or glues, is excellent for producing briquettes and pellets.

Biomass cogeneration is an energy optimizing process, which produces combined electricity and heat in the form of hot water. 

A biomass cogeneration plant offers even more value for money if combined with a pellet production plant, as the recovered heat can be used in the drying process, considerably increasing the efficiency of the system.

The growth of today’s pellet industry is dependent on being able to source the raw materials. To meet this need, Costruzioni Nazzareno srl has studied the agripellet production process at length, focusing on using vine shoots, one of the most abundant agricultural by-products in Italy.
