COMPLETE WOOD PELLET PRODUCTION LINE 15 T/H – LINE FOR DRYING, CRUSHING, GRANULATION, COOLING AND PACKING OF PELLETS

Product description

The complete wood pellet production line is a professional industrial set of machines designed for the production of pellets from sawdust, wood chips, wood biomass and shredded wood waste. The line covers the entire technological process: initial wood crushing, metal separation, material conveying, buffer storage, milling, drying, feeding to pellet machines, pelletizing, pellet cooling and preparation of the finished product for packing.

The line is designed for continuous operation in plants producing heating pellets, industrial pellets and biomass pellets. Thanks to the use of multiple technological sections, the system allows the processing of raw material with increased moisture content, crushing it to the required fraction, drying it to the moisture level required for pelletizing and pressing the material into cylindrical pellets.

The system includes industrial wood pellet machines, belt conveyors, screw conveyors, bucket elevators, buffer silos, rotary dryers, cyclones, fans, air locks, dust collectors, pellet mills, a pellet cooling bin and equipment for conveying and packing the finished product.

This is a complete solution for companies looking for an efficient wood pellet production line, sawdust pellet production line, biomass pelletizing line, automatic pellet production line, industrial wood drying and pelletizing line and complete technology for the production of heating pellets.

Application

Wood pellet production, sawdust pellet production, wood chip pellet production, wood biomass pellet production, pellet production from sawmill waste, heating pellet production, industrial pellet production, wood raw material processing, biomass processing, pellet production plants, sawmills, biomass processing plants, energy plants, companies processing wood waste, companies producing ecological fuels.

Technological process

The raw material first enters the crushing section, where wood or larger wooden elements are crushed into smaller fractions. The material is then transported to the milling section, where hammer mills prepare the proper material structure for the pelletizing process.

The next stage is drying. The line uses rotary dryers designed to reduce the moisture content of the material. The drying section allows the material to be dried from approximately 40–45% moisture content to approximately 15%, so that it meets the requirements of the pelletizing process.

After drying, the material is transferred to the pelletizing section. The line includes five vertical ring die wood pellet machines, model LKJ850. Each machine is designed to press dried material into pellets. The pelletizing section is designed for efficient pellet production, and the machines require the appropriate moisture content of sawdust, approximately 15–18%.

The finished pellets are then transferred to the cooling section and further conveying system, and can then be directed to packing or loading.

Process data and parameters

The initial crushing section prepares the raw material for further processing and enables the material to be crushed into wood chips. The section is equipped with a 250 kW motor and reaches a capacity of approximately 25 t/h.

The milling section uses two hammer mills, each equipped with a 250 kW motor. The purpose of this section is to finely crush the material to the fraction required for the pelletizing process. The system works with dust collection to reduce dust in the production plant.

The drying section uses two rotary dryers with a diameter of 2 m and a length of 23 m. The purpose of the dryers is to reduce the moisture content of the raw material from approximately 40–45% to approximately 15%, so that the material meets the requirements of the pelletizing process.

The pelletizing section includes 5 LKJ850 wood pellet machines. Each pellet machine is designed for producing pellets from dried wood material. The pelletizing section is designed to achieve a capacity of approximately 15–20 t/h.
