Not only clay bricks and roofing tiles...

Bongioanni Macchine is able to manufacture machines for specific exigencies in sectors which are different from the clay bricks and the roofing tiles, such as ceramic, refractory, mining, wastes disposal, extrusion of different materials. More in detail:

Ecology sector: of waste products, composting of municipal solid wastes.

Commissioned by one of the major Italian groups of the sector in a plant located in the south of the Peninsula, have been realized some units of grinding and mixing of the municipal solid wastes, designed and manufactured to create the conditions necessary for a correct composting.

The grinding unit allows the reduction of the municipal solid wastes to a size between 3 and 5 millimeters without compacting them. After several attempts with the use of mills and other crushing machines, the owners have contacted Bongioanni Macchine that has developed the project and, with a moderate investment, has customized a machine making it suitable for this purpose. The Company which operates in the recycling sector, satisfied of the result, has commissioned a mixing and wetting unit for a particular waste. Such a unit allows to mix more than 7 m³ of water in approx. 10 ton of material, homogenizing the mixture as required by the transformation process.

Mining sector: and transformation of nickel, recovery and recycling of the dusts.

A French Company belonging to one of the most important worldwide groups that deal with the extraction and transformation of almost pure iron-nickel, in 2002 has commissioned to Bongioanni Macchine the design and realization of an installation to recover the dusts that, even if still rich of nickel, in the traditional production process were treated as scraps and scattered in the atmosphere.

The project consists in picking up the dusts at a high temperature from the different points of the installation and convey them, through a system of pneumatic transport, to some dosing hoppers. Here the dusts are metered in a right proportion with the water and thanks to a series of special mixers the dust and the water are properly amalgamated thus obtaining a moisture that is then compacted.

The most tricky aspect, is to obtain a constant and precise stoichiometric ratio between the dust and the mixing water to maintain constant the mechanical features necessary to make the mixture suitable for the last phase of the transformation. The success of the operation has brought to a double result since other than dedicating the right attention to the ecological aspect, the mining Company has obtained an important economical return, recovering almost 60 ton/hr of semi manufactured material that before was scattered in the atmosphere during the final phase of the transformation.
