Reception Hopper with Screw Extractor ML

Reception and automatic dosing of sawdust, wood chips, shaving woods, bark and other types of biomass.

Reception Hopper with Screw Extractor ML

The hoppers are essential equipment, for example:

  • In industrial manufacture of briquettes or pellets
  • Automatic feeding of boilers and furnaces with biomass, when companies are converting their boilers to fuel oil, gas or wood biomass.
  • In the biomass power plants.

The hoppers, also known as feed hoppers are used for receiving sawdust, wood chips, shaving woods, bark and other types of biomass in conversion processes of biomass for power generation.

The material usually arrives in trucks and is discharged directly into the hopper, which have in its bottom mechanisms to extraction and measurement, to automatically supply conveyor belts that lead to biomass furnaces, boilers and other machinery.

In the models ML biomass extraction is done by extracting one or two screws, which prevent the biomass to be trapped inside the hopper.

Subsequently the material is dosed in a controlled manner to a conveyor belt, bucket elevator or screw, depending on the installation.

The hoppers of the type ML are installed below ground level, which allows a supply truck bucket directly to the manufacturing process.

The amount of screws for the extraction depends on the desired flow rate, is the usual one or two screws with transport capacity of 5 to 400m ³ / h.
