  • Adjustable pellet size: The hardwood pelletizer machine can adjust the pellet size according to the user’s needs to meet the needs of different uses, such as being used as fuel or feed.
  • Strong adaptability: The hardwood pelleting machine can process various biomass raw materials, including straw, sawdust, wood chips, etc., and has wide adaptability in the utilization of raw materials.
  • Easy to operate: The hardwood pellet mill is easy to operate and only requires a small amount of manual operation to complete the processing, reducing labor costs.
  • High quality of finished products: The pellet fuel processed by the hardwood pelleizer machine is of high quality, with uniform pellet size and stable combustion characteristics, which can better meet the needs of users.

raw materials Requirements for hardwood pellet mill

hardwood sawdust for pellets

During the production of the hardwood pellet machine, there are certain requirements for the raw materials of wood chips, as follows:

  • Wood chip particle size: When pelletizing with a hardwood pellet maker equipment, there are certain requirements for the size of the raw materials. Generally, the size of raw materials after crushing must be less than 5mm, but the specific crushing size still depends on the diameter of the expected wood pellets and the size of the pellet machine mold aperture. If the raw materials of the hardwood pellet maker are crushed too large or too small, the output and quality of the wood pellets will be affected, and even the material will not be discharged.
  • Moisture of wood chips: When pelletizing hardwood pellets, there are strict requirements for moisture. No matter which raw material is used, the moisture must be controlled within 10~18%. If the moisture is too large or too small, the particles will easily break or It’s loose.

How does the hardwood pellet mill work?

The hardwood pellet mill mainly consists of a deceleration system, a transmission system, a pelletizing system and a lubrication system.

The working process is that hardwood powder such as wood chips with a moisture content of no more than 15% is adjusted by the auger hopper to obtain a suitable material flow rate by adjusting the frequency conversion motor speed, and then enters the granulation and compression chamber for granulation.

According to the speed of the motor, the hardwood pellets are cut by the dial cutter to meet the pellet length requirements of different customers.

How does the hardwood pellet mill work
  • The hardwood powder is fed into the two pressing areas through the die cover and the feeding scraper.
  • The pressure roller drive shaft drives the pressure roller to rotate.
  • The hardwood powder is rolled into the ring die and the pressure roller.
  • The two relatively rotating the hardwood sawdust powder is gradually squeezed by the piece, and the wood sawdust powder is squeezed into the ring die hole, formed in the die hole, and continuously extruded toward the outer end of the die hole.
  • And then the cutter cuts the formed hardwood pellets into the required length, and finally forms hardwood pellets flow enters the next process.

How to choose a hardwood pellet mill?

When choosing a hardwood pellet mill, you need to pay attention to the following aspects:

Budget

The more funds you have, the fewer restrictions there will be on purchasing a wood pellet mill. The price of hardwood pellet mill machines varies depending on the brand and model, so you need to make sure you have enough budget to purchase the equipment you need. While price may be a factor in your choice, you want to make sure you don’t compromise on quality and performance.

Hardwood pellet production scale.

The larger the scale, the greater the investment and the higher the profit. You need to choose a hardwood pellet milling machine that can meet your production needs. Machines capable of producing large batches of wood pellets may be more expensive, but if you need to produce large quantities of wood pellets, the investment is worth it.

Raw materials.

Depending on the raw materials you can obtain, according to the type of pellets you need to process, and according to the customer groups you will sell to, you need to choose a hardwood pellet mill that is suitable for your use.

Some wood pellet press machines can handle a variety of wood and other raw materials, while others can only handle specific types of raw materials. Make sure you know your raw materials and choose a machine that can handle them.

If you want to enter markets such as the European Union, try to choose high-quality hardwood chips or wood chip raw materials as raw materials, so that the processed pellets can meet the wood pellet standards of each country.

Factory building.

This includes considering the size and weight of the machine, and whether your workplace has enough space to store and operate it. Make sure you have enough space to house the hard wood pellet extruder machine and wood pellet production line you choose, and that the operating environment meets safety requirements.

In addition to the budget and raw materials, RICHI’s engineering team will customize an exclusive process plan, equipment layout, factory layout design, and civil construction plan for you based on the production scale and factory size, so that your entire hardwood pellet production plant construction will receive a full range of technologies support.

Complete hardwood pellet mill plant process design

What is the workflow of wood pellet fuel equipment? It includes screening, crushing, drying, mixing, granulating, cooling, dust removal, packaging and other links of raw materials. This is explained in detail below.

hardwood pellets processing plant design
  1. Screening: The raw materials are transported to the screening machine through the auger conveyor for screening, and larger wood blocks or nails and other debris are removed.
  2. Crushing: crushing wood raw materials that do not meet the size requirements. This section is more troublesome. Depending on the actual raw material conditions, peeling machines, wood splitters, slicers, wood board crushers, wood chip crushers, etc. may be used. Crushing equipment.
  3. Drying: Wood molding fuel has strict requirements on the moisture content of raw materials. After the raw materials are screened, they are transported to the airflow dryer through the auger conveyor for drying by hot air.
  4. Cyclone separation: During the transportation process after the raw materials are dried, a large amount of moisture exists after passing through, and the moisture is discharged through the cyclone separator.
  5. Material transportation: The logistics transmission of this system requires corresponding transmission equipment. As needed, this design uses screw conveyors, auger conveyors and bucket elevators to transport materials to the corresponding equipment.
  6. Pelletizing: The hardwood pellet mill is a key equipment in the production line, and the density of the processed wood pellet fuel can reach 1.0-1.3 tons/cubic meter.
  7. Cooling: When discharging wood, the temperature of the pellet fuel is as high as 80~90°C. The structure is relatively loose and easy to break. It must go through a counter-flow cooling system. After cooling to normal temperature, it can be bagged and stored or passed through the belt conveyor and elevator. Send to silo. This set of equipment is equipped with a cooling fan and a cyclone separator, which can return the separated powder to the previous process for re-granulation.
  8. Screening: The cooled pellet fuel is screened using a vibrating screen. It needs to be screened to screen out the broken materials to ensure the factory quality of hardwood pellet fuel. The screened out scraps are returned to the previous process for re-granulation.
  9. Finished product warehouse: The processed finished hardwood pellets are sent to the finished product warehouse via the elevator to prepare for bagging and storage.
  10. Bagging and warehousing: This design uses a packaging conveyor for measurement, tape packaging, and delivery to the finished product warehouse.
  11. Silo system: According to user needs, bulk material transportation can also be used, that is, the hardwood pellet fuel is sent directly from the finished product warehouse to the silo through the belt conveyor and elevator for storage, and the pellet fuel is sent directly to the user by vehicle.
