Nestro production lines

We manufacture equipment that can be easily integrated into a complete Nestro briquette production line, adapted to the specific needs of our customers.

Processing stages:

• grinding wood or chips to the size of sawdust;
• sorting sawdust by size;
• drying sawdust to 8-15%;
• pressing sawdust into briquettes in an impact-mechanical press;
• cooling briquettes;
• packing briquettes into bundles.

Purpose

for the production of environmentally friendly solid fuel with high heat output: fuel briquettes (Nestro standard)

Advantages

• fuel with a calorific value of 4400-4700 kcal/kg is produced (at the level of coal);
• briquetting is carried out without adding adhesives;
• industrial waste from wood processing and the production of edible and technical oils is utilized;
• an ecological energy carrier from renewable sources is created.

Raw materials

sawdust, sawdust, sunflower husks, waste from the cleaning separator

Raw material requirements

For the successful and productive production of these fuel briquettes, the press must receive sawdust:

• with a fraction of 2-15 mm;
• dried to 8-15%;
• with a mineral impurity content of up to 3%.

It should not be stored for more than 2 years before use, be subjected to heat treatment at a temperature of more than 70°C, or come into contact with toxic substances.

 

Dried to 8-15%, the raw material from the loading hopper is fed by a screw feeder into the underpress, in which the raw material is pre-compacted.

From the underpress, the raw material is fed into the forming matrix, in which the product is taken and compacted using a punch, and then a briquette with a diameter of 70 mm is formed.

From the forming matrix, the briquette is fed through the cooling chute into the dividing device.
