The specific uses of biomass pellet mills are as follows:
Pellets processed by biomass pellet mills can be used in many industries and are suitable for many raw materials, but for now, biomass pellets are mainly used to process fuel pellets.
The applicability of biomass granulator is extremely wide, and this wideness is mainly reflected in the applicability of raw materials. According to different raw materials, biomass pellet mill machines can be divided into the following:
| Model Specifications | HKJ25M | HKJ35M | HKJ45M |
| Main engine power (KW) | 22 | 30×2 | 55×2 |
| Feeding power (KW) | 0.75 | 0.75 | 1.5 |
| Forced feeding power (KW) | 0.37 | 0.75 | 1.5 |
| Output (t/h) | 0.1-0.2 | 0.5-0.8 | 1.5-2 |
The primary working principle of the biomass pellet making machine is to compress agricultural and forestry waste through high temperature to form pellet fuel with high density and high combustion value.
Compared with traditional fuel and coal, this new type of fuel has higher combustion efficiency and generates greater heat. It is worth noting that during its combustion process, the emission of pollutants is extremely low, which is beneficial to environmental protection.
In the current society, energy shortage and environmental pollution problems are becoming increasingly serious, and the application of biomass pellet machines has great prospects. Its use can improve energy utilization and reduce the impact of waste on the environment. It can also reduce the company's energy costs and improve production efficiency.
Wood and agricultural biomass pellets boost the potential as bio-fuels toward power production in tertiary and residential sectors. The production of pellets, however, is a multi-stage process where the supply-processing phases and the overall energy input strongly depend on the characteristics of the input biomass.
Generally speaking, just using a biomass pelletizer cannot support efficient biomass pellet processing, and equipment such as good quality biomass sawdust hammer mill, high efficiency wood chips, high drying efficiency biomass rotary dryer, biomass pellet cooler machine, pellet screening machine, biomass pellet bagging machine, etc., sre also required.
1.How to make biomass pellets with Complete Biomass Pellet mill plant
Wood and agricultural biomass pellets boost the potential as bio-fuels toward power production in tertiary and residential sectors. The production of pellets, however, is a multi-stage process where the supply-processing phases and the overall energy input strongly depend on the characteristics of the input biomass.
Generally speaking, just using a biomass pelletizer cannot support efficient biomass pellet processing, and equipment such as good quality biomass sawdust hammer mill, high efficiency wood chips, high drying efficiency biomass rotary dryer, biomass pellet cooler machine, pellet screening machine, biomass pellet bagging machine, etc., sre also required.
Complete biomass pellet manufacturing process:01Biomass materials supply
This section includes the collection, transport, and storage of biomass to the collection point; green wood is mechanically removed, and pruning residues are air-dried.
02Biomass pre-treatments section
This section includes the mechanical processes such as converting wood into wood chips (except when starting from sawdust), the removal of ferrous material, drying, milling, and conditioning. The wood chips are typically dried in heaters fed with conventional fuel, although sometimes the heaters use wood chips as fuel. The most common driers use rotating drums with flow of air, in which the wet biomass does not stick to the drum surfaces and over-heating is minimized.
If the biomass can withstand contact with the combustion products, the simplest and cheapest system is a direct-heating wood drier, in which the wet biomass is in contact with hot combustion gases. Alternatively, the wet biomass can be dried using hot air. The dried biomass is further milled to obtain wood chips with average length of 3 mm and to homogenize the end product.
The most common biomass material hammer mills use rotating hammers, and the material is shifted through the machine using compressed air. Sometimes, the secondary milling is bypassed by a simple tilted-plane mechanical size selector.
Additives aimed at improving biomass quality and extrusion behavior can be added to the raw materials during this section.
03Pelletizing section
This section involves the physical production of the biomass pellet by applying mechanical pressure on the biomass through a suitable holed plate, to obtain pellets with diameters in the 2-12 mm range and heights in the 12-18 mm range. The main technical parameters of the biomass pellet making machine are as follows: canal geometry, number and speed of pressurizing drums, ratio between diameter and length of canals, and distance between drum and holed plate. The devices may use a vertical cylindrical holed drum or a plane plate.
04Post-Treatments section
These sections include cooling, screening (selection of pellet size), collection, and storage in silos or sacks for subsequent sale. The cooling section is critical for the stabilization of the product, since, during the biomass pelletizing section, the pellets reach comparatively high temperatures (90-95ºC) and are typically obtained via forced exposure to air at room temperature. Pellets with a non-standard size are mechanically removed to minimize development of dust in the storage areas.
Not all raw materials require mixing. Nevertheless, if necessary, mixers are used after the raw material has been milled and dried to: get a more consistent material blend to be fed into the biomass pellet mill machine when the raw material for biomass pellets presents significant changes in moisture percentage, binding properties or material density; produce a homogeneous mixture of raw materials in the case of pellets made up of different raw materials.
Once the biomass making raw material has been mixed and its consistency is high enough, it may require the addition of other constituents able to increase the productivity of the pellet mill and enhance the final properties of the biomass pellets produced.
Additives play a major role in wood pellet characteristics. They are a subject of major interest: as binding agents for the biomass raw material, they serve to improve pellet durability and physical quality, reduce the dust, improve pelleting efficiency and reduce energy costs.
A maximum content of 2% of additives is permitted in woody pellets. No limitation exists for the non-woody pellets, though it is required to indicate the type and quantity used. To produce wood pellets with desired physical and thermal characteristics, the additive should be suited to the right biomass material. The most common additives are:
Lignin is a natural, optimal binder of biomass, because it melts under the heat of the pellet mill for biomass pellets. If the lignin content of the biomass is low, it may be necessary to add other additives, however. One of the simplest binders is vegetable oil, which also aids the biomass pellet line production process by reducing the frequency of blocked dies, but the most widely used substance overall is starch.
