Working principle of MZLH420 biomass granulator

The crushed biomass material enters the die cover through the forced feeding mechanism, and is evenly fed into the two pressing areas in the ring die, i.e. the wedge-shaped space formed by the two pressing rollers and the ring die, through the centrifugal force generated by the feeding device and the rotation of the ring die and the action of the feeding scraper.

Under the strong squeezing action of the ring die and the pressing roller, the material is gradually compacted, squeezed into the die hole of the ring die and formed in the die hole.

Since the extrusion of the biomass material between the ring die and the pressing roller is continuous, the formed material is continuously discharged from the die hole in a columnar shape, and then cut into biomass pellets of the required length by the cutter.

How to process biomass pellets with whole set biomass pellet press system?

How to process biomass pellets with complete biomass granulator system?

Process flow of biomass pellet machine line: raw material collection → raw material crushing → raw material drying → mechanical pelletizing and molding → mechanical cooling → bagging and sales.

How to process biomass pellets with complete small biomass pellet machine plant
  1. Raw material collection:
    The raw materials of biomass pellets are usually renewable organic waste such as wood waste, agricultural waste, animal manure, etc.
    The process of collecting raw materials should ensure the diversity of raw material sources to reduce dependence on a single source. At the same time, the collection process should consider environmental protection to avoid pollution to the environment.
  2. Raw material pretreatment:
    Raw material pretreatment mainly includes crushing, dry blasting, and sorting. Crushing is mainly to break large pieces of raw materials into small pieces for subsequent processing.
    Dry blasting is mainly to remove moisture from the raw materials to facilitate pellet pressing and prevent pellets from mildewing during storage. Sorting is mainly to remove impurities in the raw materials, such as stones, metals, etc., to ensure the quality of the pellets produced.
  3. Biomass granulation:
    After pretreatment, the raw materials will enter the biomass granulation link. This link mainly uses high-pressure compression to make the raw materials into pellets. During the pressing process with biomass granulator, the pressure and temperature should be controlled to ensure that the produced pellets have sufficient strength and stability.
  4. Pellet cooling:
    The pressed biomass pellets need to be dried to remove the moisture and improve the stability of the pellets. Cooling usually uses natural cooling or forced cooling. The appropriate cooling method is selected according to the specific production conditions and ambient temperature.
  5. Pellet packaging:
    Graded biomass pellets need to be packaged to prevent contamination or damage during transportation and storage. Packaging materials should be environmentally friendly and recyclable materials, such as paper bags, woven bags, etc.

How to choose a biomass pellet granulator machine?

When choosing a biomass granulator machine, you need to carefully consider the following core factors. RICHI provides the following suggestions:

  • First, the type of raw material is the top priority. There are many types of biomass. Raw materials such as wood, straw, coconut shells, and palm shells are more suitable for biomass pellet machines without conditioners; while raw materials such as forage grass, alfalfa, hay, miscanthus, elephant grass, and straw, if used for processing pellet feed, are more suitable for the MZLH sharp forage pellet machine.
  • Secondly, the pelleting capacity should not be underestimated. The size, compression ratio, and diameter of the biomass pellets will determine the pelleting capacity you need. The greater the motor power, the stronger the pelletizing capacity, but correspondingly, the energy consumption will also be high.
  • Furthermore, the ring die aperture is also the key. The most suitable ring die aperture should be selected according to the actual needs and product specifications.
  • In addition, the brand and quality of the equipment are equally important. Biomass granulator machines of well-known brands often have guaranteed quality and after-sales, and enjoy a longer warranty period to protect your investment.
  • The selection of equipment specifications and models is equally important. Different pelletizing purposes and outputs require you to choose the most suitable model.
  • Safety should not be ignored. Choosing a biomass wood pellet machine equipped with safety protection devices, such as automatic shutdown and overload protection, will provide a solid safety guarantee for your production.
  • Cost and budget are also factors you must consider. Within the budget, it will be a wise move to choose the most cost-effective biomass granulator.
  • Easy maintain. At the same time, a machine that is easy to maintain and clean will save you a lot of later maintenance costs and time, ensuring the long-term stable operation of the equipment.
  • Finally, the degree of automation will directly affect your production efficiency and labor intensity. According to production needs, choosing an automated biomass wood pellet maker will bring qualitative changes to your production.

In summary, when choosing a biomass pellet processing machine, you need to comprehensively consider factors such as raw material type, pelletizing capacity, ring die aperture, equipment brand and quality, equipment specifications and models, safety, cost and budget, maintenance and cleaning, and degree of automation.


How to choose a biomass pellet granulator manufacturer?

In the biomass pellet process, the equipment used needs to be selected according to factors such as the type of raw materials, material status, production scale, and pellet requirements. This leads to the configuration of the equipment being determined according to customer requirements.

From raw material pretreatment to pellet packaging, the models and specifications of the equipment vary. At this time, it is very important to choose a reliable manufacturer. However, there are many biomass pellet machine manufacturers. What issues should be paid attention to when choosing?

1. Look at the age of the manufacturer

Generally speaking, the longer the biomass pellet granulator machine manufacturer has been established, the better its strength and quality are, and the larger the scale of the manufacturer is. The product design, R&D, production, and after-sales service team are relatively complete and formal. It is relatively worry-free to cooperate.

2. Manufacturer information query

Now it is very convenient to query company information online.

When choosing a biomass granulator manufacturer, first understand the business scope of the biomass granulating machine manufacturer, whether the qualifications are complete, whether it has a production and operation license, whether there are any contract disputes, etc.

These clear understandings can effectively eliminate cooperation risks and reduce the chances of cooperating with risky companies.

3. Visit the manufacturer

It is an indispensable part to go to the manufacturer for on-site inspection when purchasing a biomass granulation machine.

Through the inspection, some manufacturers whose publicity is greater than their strength can be eliminated, and through the inspection, a detailed understanding of the strength, production site, production process, after-sales service and other conditions of the equipment manufacturer can be obtained.

4. Look at the cooperation case

The manufacturer will return to the equipment it sells every once in a while to record the operation and service life of the equipment in order to improve future production.

You can visit the oil factory that cooperates with the equipment manufacturer to have a more comprehensive understanding of the operation of the biomass pellet machine, the quality of the pellets produced, and the after-sales service.

This is also an investigation of the quality of the biomass granulator and the manufacturer’s after-sales service. Through the inspection of the cooperation case, there is an estimate of the service life and production capacity of the equipment.

The equipment of the biomass pellet line is closely linked. No matter which equipment has a problem, it will be a loss for the entire biomass pelletizing plant. Therefore, it is particularly important to choose a reliable equipment manufacturer.

You can refer to the above suggestions when purchasing. Choose more alternative manufacturers and compare them slowly. If you spend more energy and inspection in the early stage, you can reduce the risk of losses caused by biomass granulator problems in the later production.
