The difference between biomass pellet machines with flat and circular molds

There are significant differences between the flat model biomass pellet machine and the ring model biomass pellet machine in multiple aspects. The following is a detailed comparison of these two models:

Biomass pellet machine

Working principle and structure

  • Flat mold biomass pellet machine: adopts a pressure roller granulation mode, consisting of a feeding machine, pressure roller, mold, conditioner, cutter, and a series of components. Its working principle is to squeeze the raw materials in the mold through the pressure roller, forming granular fuel. The structure of the flat mold pellet machine is simple and the cost is relatively low.
  • Ring mold biomass pellet machine: It adopts the ring mold pressing mode and consists of a feeding machine, pressure roller, mold, cutting knife, etc. Unlike flat die pellet machines, ring die pellet machines do not require auxiliary equipment such as conditioners during the pressing process. Its working principle is to extrude raw materials into particles through the interaction between a rotating ring mold and a fixed pressure roller.

Scope of application and raw material processing

  • Flat mold biomass pellet machine: suitable for processing various biomass materials such as plant straw, aloe vera, wheat straw, rice straw, wood chips, etc. Due to its structural characteristics, the flat die pellet machine has good adaptability when processing different raw materials.
  • Circular biomass pellet machine: also suitable for processing raw materials such as sawdust, wood powder, peanut shells, rice husks, cottonseed hulls, straw, etc. The ring mold pellet machine performs well in processing high fiber, low viscosity raw materials, and can efficiently convert these raw materials into pellet fuel.

Particle characteristics and applications

  • Flat mold biomass pellet machine: The diameter of the produced pellets is usually within the range of 6mm, 8mm, 10mm, etc., and the length can be adjusted according to user needs. Particles have excellent properties in terms of hardness, density, and water resistance, making them suitable for use as fuel or feed.
  • Circular biomass pellet machine: The particle diameter produced can be adjusted between 2.5mm and 12mm, and the particle shape is generally cylindrical. The pellet fuel produced by the ring mold pellet machine has high calorific value and combustion efficiency, and is suitable for household or industrial heating applications.

Production efficiency and energy consumption

  • Production efficiency: Circular biomass pellet machines typically have high production efficiency due to their high rotational speed and large output. Although the flat mold pellet machine has a simple structure, its efficiency may be slightly lower than that of the ring mold pellet machine in large-scale production.
  • Energy consumption: The energy consumption of two types of pellet machines needs to be evaluated based on specific models and process parameters. Generally speaking, users should pay attention to the energy consumption of the equipment when choosing, and choose devices with lower energy consumption to reduce production costs.

operation and maintenance

  • Easy operation: The circular biomass pellet machine usually adopts an intelligent control system, which is relatively simple to operate and easy to maintain. Although the operation of the flat mold pellet machine is not complicated, it may not be as intelligent as the ring mold pellet machine in some aspects.
  • Maintenance cost: The flat mold pellet machine has a relatively low maintenance cost due to its simple structure. Although the structure of the ring mold pellet machine is more complex, its maintenance cost is gradually decreasing with the advancement of technology and the promotion of standardized production.

In summary, both flat mold biomass pellet machines and ring mold biomass pellet machines have their own advantages and disadvantages. The choice of which type of biomass pellet machine to use depends on specific factors such as raw materials, usage, output, energy consumption, ease of operation, price, and after-sales service. Users should fully understand the characteristics of various types of biomass pellet machines before purchasing, and make comprehensive considerations and choices based on their own needs.
