making biomass fuel pellets from rice husk pellets

The rice husk pellets every day gain a more important place in the preference and respect of the markets; Ideal as a source of renewable alternative energy to non-renewable fossil fuels, which makes it especially attractive in a world where ecological measures have become somewhat trendy. 

Recently, a trial run is done for making rice husk pellets by use of our ZLSP series small pellet machine.
View the brief testing report below, or you are welcome to contact us for more details!

Conclusion of the Rice Husk Pellet Machine Trail

Some of the main conclusions of the pelletizing trial is listed below for your reference. If you are planning to start making your own pellets from rice husk or rice straw, and need some more suggestions and guidance. Don't hesitate to send us an inquiry and tell us your capacity requirement, then we can help your choose the most suitable and cost effective pellet making machine.

   Rice Husk is Good Choice for Pellet Production.

Whether the material has been crushed or not , it can both produce pellets very well. Just a little difference with the final capacity. The capacity will a little bigger if the material after crushed.
 

   R-type Pellet Machine is Better for Processing Rice Husks/Hulls

We suggest to choose our R type pellet machine for making rice husk pellets. The final result is better compare the D type wood pellet machine.
 

   The moisture content is suggested to be around 20%.

The final result of running test is just related the moisture of material ( best suitable moisture for your material is 20%) and the compression ratio of the die( the most important reason) Please see the video below,because the test time is too long , the video volume is too big ,so we delete some contents and keep the effective parts . In the first half of the video we use the raw material, in the second half of the video we use the material after crushed. The final running result of your rice husk is very well.
 


Main Process of Rice Husk Pellet Production

The production of rice husk pellets usually includes the following processes: 

  • Rice Husk Crushing (optinal): To optimize the production of granules as much as possible, it is suggested to reduce the size of the rice husk. For this hammer mill is the equipment needed.
  • Pelletizing: There are flat die pellet machine for small scale production with below 800kg/h. Ring die pellet machine is suggested for large production.
  • Packing (optional): Packing is included in most medium to large scale pellet production line. 


The ABC Machinery, has an excellent technology and experience in the matter when pelletizing rice husk. We can offer both single small pellet machine for home use and turnkey project plan for complete line of rice husk pellet production. 

 

The Potential of Rice Husk in Manufacturing Biomass Fuel Pellets


global rice production
 

After maize, the second highest grain production place in the world is rice. Rice is an essential part of the diet of a large part of the world's population. Especially in Asia, where many people consume it daily, also in Latin America and in certain places in the Middle East.

Milled Rice Production by Country in 1000 MT

The difficulties in the biodegradability of the rice husk prevent that 70% of the more than 100 million tons of rice husk produced around the world are properly used, remembering that the weight of the rice husk represents the 20% of the weight of the rice. According to several studies, the world demand for paddy rice, by the year 2020 will reach 780 million tons and will continue to produce rice husks per ton with a tendency to continue wasting in the absence of a solution. Due to the increase in rice planting, at the same time, the rice husk has become an economic alternative to generate income for the planter.

Typical rice husk properties analysis
Bulk Density (kg/m3) 96-160
Length of Husk (mm) 2.0-5.0
Hardness (Mohr's scale) 5.6-6.0
Ash (%) 22.0-29.0
Carbon ≈35.0
Hydrogen 4.0-5.0
Oxygen 31.0-37.0
Nitrogen 0.23-0.32
Sulphur 0.04-0.08
Moisture 8.0-9.0

 

High Caloric Value of Rice Husk

In comparison with wood, rice husks are also an effective material in terms of combustion. Normally, rice husks tend to be used as combustion materials due to the caloric value they contain. Estimated at 14 MJ I kg, this value is equivalent to 35% of that contained in the diesel or the well-known "bunker oil", which at the same time has a caloric value of 40.5 MJ I KG.
