C. F. Nielsen - Consumer Briquetting Plant 600 - 900 kg/h
Briquetting Plant for production of 600 - 900 kg/hour of Consumer Briquettes from dry Softwood or Hardwood waste... We recommend a single line solution with a BP 4000 or a BP 5000 briquetting press with a 6-10 m3 dosing silo or in combination with a large silo including automatic discharge system. The BPU 4000/5000 with BBCS control system are competitive alternatives.
Requirements for raw material
- Particle size has to be less than 15x5x2 mm, otherwise a grinding process has to be introduced. A hammer mill with 10-15 mm screen size will normally give the requested particle size.
- Moisture content of the raw material should preferably be in the range 10–12%
- otherwise a drying process or moisture increasing system has to be introduced.
- Raw material must be suitable for briquetting and tested if any doubt.
Testing of raw material
We are ready to perform a test briquetting based on you supplying us actual dry raw material, with correct particle size and moisture content. The test will show the expected quality of the final product and let us determine, whether any additives need to be added.
Storage facility for dry raw material
Normally we can combine our solution with your existing or planned storage solution, whether this is a large silo, a bunker or similar.
Briquetting control system
A frequency controlled dosing screw feeds an exact amount the raw material into the press in a steady flow. Level switches in the silo signals the conveyor when refilling of the silo is required.
All vital functions of the press are controlled by the advanced and operator-friendly BBCS or ABCS Control System including a Siemens PLC. This system is capable of keeping the set capacity within +/- 50 kg/hour even with fluctuating density of the raw material.
Preferred type and dimensions of briquettes
- The BP 5000 press produces Ø75 mm briquettes. These briquettes are normally stacked and wrapped in 10 kg packages, each with 7 or 8 briquettes in a suitable length.
- The BP 4000 produces Ø60 mm briquettes, that followingly are shortened in suitable lengths for packaging in cardboard boxes or foil wrapped.
Transportation, cooling and shortening of the briquettes
The briquettes are produced in a continuous string and conveyed to the BS 350 automatic saw or a Briquette breaker via the min- 30 m long, straight cooling line. The long cooling line is very important to allow the briquette string to cool down and harden before being handled in the shortening and packaging line. Outdoor cooling lines have to be covered.
Packaging solution
From the saw, the briquettes are conveyed to the packaging unit and shrink oven. Broken or too short briquettes are automatically ejected from the line. A label is normally inserted just before the package enters the shrink wrapper.
We generally see 3 different options.
- Manual sorting and packaging in cardboard boxes
- Recommended for the smaller plant with only 1 or 2 shift operation
- Manual sorting, semiautomatic packaging and shrink wrapping.
- Followed by manual palletizing of the briquettes
- Automatic sorting and shrink wrapping.
- This requires high quality briquettes and a sorting system inserted after the saw or breaker.
After palletizing, each pallet has to be foil wrapped for safe transport and storage.
Utilization of consumer briquettes
Consumer briquettes are CO2 neutral and suitable for burning in woodstoves and open fireplaces. We might be able to connect you to a potential buyer etc.

The press may be placed separately in an existing building or under a deck in a large storage silo and feed via an integrated discharge system.
