Briquette production from a wide variety of waste

In any production process, it is increasingly common to consider the value of materials that were previously considered waste. In this way, instead of being seen as an obstacle to be eliminated, waste acquires value, as it can be used as raw material or to generate energy.

Sinducor has introduced machines to the market for producing briquettes from a wide variety of waste materials. The main advantages of these machines are their simplicity, compact size, and ease of use. These characteristics make them ideal for utilizing waste at the source. The machine includes a material hopper, a cooling system, and operates automatically. It requires only a power supply.

The materials that can be processed are very diverse and include shavings, sawdust, small chips, straw, grain, cereal husks, paper, cardboard, etc., and also non-ferrous metals such as aluminum, copper, and brass. The materials to be treated must not have more than 20% moisture content or exceed 25 mm in size.

The resulting product consists of compact and stable briquettes with a diameter between 50 and 80 mm. Pressing is done exclusively by hydraulic pressure without the need to add binders.

Waste valorization is achieved in two ways. On the one hand, a significant volume reduction is achieved, which can reach up to 90%, and on the other, a product is obtained that can be used for energy recovery and has improved combustion characteristics compared to the unagglomerated material. Additional advantages include reduced storage and transport costs, cleaner and easier handling, reduced dust emissions, and increased safety.

The resulting briquettes have a calorific value that depends on the raw material used. For example, typical sawdust waste from a sawmill produces briquettes with a calorific value per kilogram equivalent to 500 ml of diesel fuel.

The range of briquetting machines is very broad, including everything from very compact, small-sized models that produce thirty kilograms per hour to models that exceed five hundred tons per hour. These machines are complemented by crushers that allow for conditioning the material if it is not of the appropriate size.
