Applications Of Palm Fiber Pellet Machine & Pellet Production Line

Fuel plays an important role in household, business, and industrial sectors. Especially, in business and industrial uses which about 60% of energy used are imported. Thus, sustainable fuel energy development in Thailand and similar countries must consider limited energy resources and there usage.

Selected fuel must be cheap, abundant, and environmental friendly. According to the policies of Thailand and other countries to promote biofuel as renewable energy, oil palm cultivated area has been increasing.

Crude palm oil production left large amount of palm fiber and shell as waste. To increase their value, palm fiber and shell were selected to be raw materials of pelletized fuel.

Despite most wastes from palm oil production are currently used, i.e. palm shell is sold to be fuel in other industries or used as raw material for pellets, empty palm fruit brunch is used for mushroom production, and palm fiber is used as fuel for electricity and steam production in factories; a lot of palm fiber is still left as waste because its bulky particles which are difficult for transportation.

Palm fiber is a possible raw material to be pelletized to be used in industrial furnace. There were a lot of researches reported that biowaste such as bean pod, cereal husk, cotton waste, wheat straw, etc.; can be pelletized to be utilized as good fuel.

5. Adopting international advanced technology on this palm kernel pellets making machine: German gun drill and vacuum furnace heat manufacturing process in ring die making to ensure the pellets smooth and of high quality.

Working Principle Of Palm Fiber Pellet Machine & Pellet Production Line

Generally, the EFB pellets production is in large scale. Then our ring die EFB pellet machine is the most suitable machine for compressing the high density EFB fiber. Adopt high-precision gear driving, the output is improved by about 20% compared with the belt drive one. Imported high-quality bearings and oil seal are adopted to ensure efficient, stable and low-noise operation.

The mixed or tempered pulverized palm fiber/palm shell material passes through the chute through the compression mold cover, and is uniformly fed into the two pressing areas in the palm kernel cake(PKC) pellet machine ring die by gravity, centrifugal force generated by the rotation of the ring die, and the action of the feeding scraper.

Under the strong extrusion of the palm fiber pellet machine rollers, the material is gradually compacted and extruded into the die hole of the ring die to form. Since the extrusion of the material between the die rollers is continuous, the formed material continuously emerges from the die hole. The column is discharged, and then a cutter is cut into the required length of particles, and then enters the next palm pellet production line process.

Guidance of EFB pellet production by palm pellet making machine

The optimum ratio of palm pellet fuel made only by palm fiber was 50:10:40; palm fiber, water, and waste glycerol respectively. In the best practice condition; particle size was smaller than 2 mm, adhesive glycerol was heated.

From the explained optimum ratio and ingredient, pelletizing ratio was 62.6%, specific density was 982.2 kg/m3, heating value was 22.5 MJ/kg, moisture content was 5.9194%, volatile matter was 88.2573%, fix carbon content was 1.5894%, and ash content was 4.2339%, which was higher than the standard.
Guidance of EFB pellet production by palm pellet making machine

Mixing palm shell into palm fiber raw material reduced ash content of the pellets. The optimum raw material ratio, which minimizes ash content, was 80 to 20 palm fiber and palm shell respectively. Adding palm shell reduced ash content to be 2.5247%, which was higher than pelletized fuel standard but followed cubed fuel standard.

At this raw material ratio, pelletizing ratio was 70.5%, specific density was 774.8 kg/m3, heating value was 19.71 MJ/kg, moisture content was 9.8137%, volatile matter was 86.2259%, fix carbon content was 1.4356%, and compressive force was 4.83 N.

Raw material characteristics of palm pellets made by palm fiber pellet machine

Physical and chemical composites of palm fiber and palm shell

Palm fiber contains significantly high ash content (9.84%). It composes of 43.25% carbon, 28.65% oxygen, 5.93% hydrogen, and the rests 0.12 to 0.39% are sulfur and nitrogen. It can be calculated that heating value of palm fiber is 19.62 MJ/kg which is slightly higher than palm shell (17.776 MJ/kg).

Chemical composites of palm fiber and palm shell are similar (Table 2). The main chemical composition are SiO2, CaO, Al2O3 and K2O. It is also shown that palm fiber contains Al2O3, SiO2, CaO and Fe2O3 more than palm shell.

Factor affecting efb pellets characteristics by palm Kernel Shell pellet machine

Experiment had been done to study particle size, raw material: water: waste glycerol ratio, temperature of adhesive (waste glycerol), palm fiber and palm shell ratio; to find optimum condition of ingredient for pelletized efb pellet fuel. The best practice efb pellets made by oil palm fronds pellet machine was considered by pelletized percent, density, heating value, ash content, moisture content, volatile matter, and fix carbon content.
Guidance of EFB pellet production by palm pellet making machine

Effect of particle size distribution on pellets made by palm fiber pellet machine

Particle size of palm fiber affects pelletized percent, specific density; but do not affect moisture content of pellets and ash content which is different insignificant values. Using mixed particle size (<2 mm), the palm pellets made by palm wood pellet machine will have more than 50 pelletized percent.

Moreover, the efb pellets have high specific density and lowest ash content. For small particle (<0.5 mm), pelletized percent and density of the pellets are higher than 0.5 to 1.0 mm particles. It is also found that, the smaller particles, the higher ash content in pelletized palm fuel.

Effect of ratio of raw material, water, and waste glycerol on pelletized efb fuel characteristics

High water ratio lowers heating value of palm pellets because the higher water ratio, the more energy to dry the fuel. The higher waste glycerol ratio, the higher pellet density. Pelletized percent and heating value are also increase with glycerol ratio. Moreover, adding glycerol as adhesive increase fix carbon content of palm pelelts  but decrease pelletized percent.

Optimum ratio of ingredients of palm pellets by efb pellet machine

In generally, ash, bulk density, heating value, pelletized percent, fix carbon content, and volatile matter; affect quality of efb pellets fuel in different way - i.e. low ash increase combustibility, high bulk density fuel is convenient to be transported, heating value must be high enough to supply the need of industries, high pelletized percent will make higher yield for EFB pelletizing process, etc.

Furthermore, high fix carbon content and volatile matter pellets made by palm pellet machine are easy to be combusted but have higher smoke. In the other hand, low volatile matter pellet have higher density. From experiment, optimum ratio of pelletized fuel ingredient - raw material (palm fiber): water: waste glycerol; was equal to 50: 10: 40 respectively. Pellets at this ratio which contain only palm fiber as raw material have acceptable quality in almost all parameters according to fuel standard except ash content that higher than the standard.

Compressive strength of pellets made by efb pellet mill equipment

The palm pellets must be reacted by horizontal force due to packaging, storage, and transportation. Therefore, horizontal compressive strength of efb pellets must be considered. It was found that pellet with raw material ratio 80:20 (wt%) of palm fiber and palm shell respectively with particle size of raw material <2 mm, and added heated glycerol at optimum ratio of 50:10:40 (wt%) raw material, water, glycerol respectively; had average horizontal compressive force 5.37 MPa.

CE high level complete efb pellet production line for palm fiber/shell pellet production

The creation of waste pellets by converting waste from crude palm oil industry and biodiesel production to create compressed pellets is suitable for combustion as an energy sources. The process is easy and does not require heat input or a chemical change.

Energy content of pellets composing glycerin and biomass is 19.7 MJ/kg of pellet which is more than some another wastes such as dry wood, household waste, waste wood, and animal waste.

The efb wood pellet plant pelletisation process consists of multiple steps, including pre-treatment of raw material, pelletisation, and post-treatment. The figure below presents the schematic of the palm pellet production process.
