Briquetting lines
The production of biofuels from waste wood and biomass is a multi-stage technological process consisting of the following steps:
- Supply and transportation of raw materials.
- Chipping.
- Drying.
- Briquetting or pelletizing.
- Finished product packaging.
An individual approach to solving the task will ensure the optimal selection of equipment and technologies to achieve maximum profitability of the project.

CHIPPING AREA
he zone consists of two stages:
1. Primary shredding is necessary for shredding of piece waste, branches, slabs into technological chips. Crushers are classified by type of crushing:
- Roller - recycles wood waste up to 80 cm in diameter, high productivity up to 50 m3 of chips per hour.
- Disk - average productivity up to 8 m3 of chips per hour. The maximum diameter of the treated waste is 25 cm.
- Shredders - low productivity up to 5 m3 per hour, are designed for primary shredding of small lumpy waste. Optimal if there are foreign objects in the wood.
All types of crushers can be produced in both mobile and stationary versions.
2. Secondary grinding is necessary to create a homogeneous raw material, which is important mainly for granulation and affects the quality of the final product (pellets or briquettes).
DRYING AREA
An important factor in the production of solid biofuels is the moisture content of the raw materials. The moisture content of the raw materials must not exceed 14% during briquetting and between 6 and 10% during granulation.
Low temperature belt dryers (operating temperature 70-90 degrees) are the optimal solution for drying.
Our dryers are reliable, fireproof and compact with a high degree of automation of the drying process.
The high class of applied technological solutions and used industrial components ensures safe operation of the drying complex. The installation of the structures in the hull of the sea container allows for assembly and a complete test cycle directly at the manufacturer's factory before shipment, thus ensuring rapid installation and commissioning on site.
BRIQUETTING
After the raw materials have been prepared (dried and shredded), it is necessary to move on to the next stage of biofuel production: the agglomeration process, ie briquetting or granulation.
Briquetted wood waste can be of various fractions, from wood dust to sawdust to wood chips. The electronic control keeps the size of the briquette constant regardless of changes in the material fraction. Without the addition of binders in accordance with DIN 51731. The calorific value of wood briquettes is 4200 - 4500 kcal / kg.
RUF & C.F. Nielsen briquetting systems process wood waste and biomass into high-quality fuel briquettes, which are in high demand in the European market, which reduces the risks associated with the sale of finished products.
PRODUCT PACKAGING
The last stage of the technological process of biofuel production is the packaging of the products. Depending on the customer's wishes and requirements, a manual, semi-automatic or automatic system for packing fuel briquettes can be installed in the finished product.

Briquetting line with automatic packaging and palletizing system in the Kaunas region, Lithuania
Briquetting line with automatic packaging and palletizing system in the Kaunas region, Lithuania
In December 2024, RMP delivered equipment, supervised installation work and commissioned a briquetting line with an automatic packaging and palletizing system at an enterprise in the Kaunas region, Lithuania. Briquetting is performed on an automatic line, the basis of which is 2 installed RUF LIGNUM R6 presses, each with a capacity of up to 720 kg/h. Pressed briquettes are moved along a conveyor to the Strojplast packaging station, where they are grouped and packed in polyethylene film. Each finished package contains 12 briquettes with a total weight of 10 kg. The packaged products are placed on a pallet by a robotic manipulator, then the pallet with the finished products is moved to the stand of the machine for wrapping the pallets with film. And now the packaged pallets are ready for shipment. The creation of an automated wood briquetting line allowed not only to solve the problem of waste processing, significantly reduce the need for personnel, but also to increase the economic efficiency of the plant.
Chipping and briquetting line with an automatic packaging and palletizing system at the "AVOTI" plant in Rezekne
Chipping and briquetting line with an automatic packaging and palletizing system at the "AVOTI" plant in Rezekne
In September 2024, "RMP" delivered equipment, carried out installation work and commissioned a chipping and briquetting line with an automatic packaging and palletizing system at the "AVOTI" plant in Rezekne. Lump waste from the main production is crushed in a chipper. Then, using a moving floor system, the bulk material is fed to a hammer mill for additional chipping. Dry homogeneous raw materials enter a 50 m3 storage bin that feeds the briquetting presses.Briquetting is performed on an automatic line, the basis of which is 3 parallel-mounted RUF LIGNUM R6 presses, each with a capacity till 720 kg/h. Pressed briquettes are moved along a conveyor to the Strojplast packaging station, where they are grouped and packed in polyethylene film. Each finished package contains 12 briquettes with a total weight of 10 kg. The packaged products are placed on a pallet by a robotic manipulator, then the pallet with finished products is moved to the stand of the machine for wrapping pallets with film. And now the packed pallets are ready for shipment.The creation of an automated wood briquetting line allowed not only to solve the problem of waste recycling, significantly reduce the need for personnel, but also to increase the economic efficiency of the plant.
Automatic line of packaging equipment in Tallinn
Automatic line of packaging equipment in Tallinn
In July 2023, our specialists implemented a project to install an automatic packaging line at a woodworking company in Tallinn, Estonia.
The line carries out automatic selection of briquettes from 3 RUF briquetting presses, their transportation to the grouper, formation of a group of 12 rectangular briquettes, wrapping the prepared group in shrink film, passing the package through a thermal tunnel and a cooling station. The line is equipped with emergency exit, leaflet feeder, briquette flow control and safety sensors. As a result, the line capacity has increased to 240 packs per hour.
Our specialists have successfully carried out high-quality installation and commissioning of all the above equipment.
