Characteristic of peanut shell pellet

  • Shape. The shape of peanut shell pellet is cylindrical. their surface is smooth with a slight sheen. According to different requirement, could produce different size pellet.
  • Heat value. Peanut shell pellet has large densities, so the combustion efficiency is high, when burning, the center temperature can reach more than 1100 degree centigrade, heat value can reach 3700 ~ 4000 kcal / kg, ash content less than 8%. Compare with coal and oil, the peanut shell also has its own unique advantages.
  • High firepower and less ash. Because of high pressure molding and larger density, the peanut shell pellet is heat- resistant with high firepower and less ash. During burning, the pellet can keep shape, no distortion and fall apart. The pellet fuel ash can as the potash fertilizer to return into soil.
  • Clean and environmental protection. Use the peanut shell pellet fuel can reduce environment pollution. When burning the pellet, ash discharge concentration is less than 40 mg / m3. So use the pellet fuel can improve air quality and avoid greenhouse effect.

  • Drying. Peanut shell pellet production is very strict with the water content of raw material. After screening, transport the the peanut shell into the dryer and use the hot wind to dry it.
  • Making pellet.  Pellet mill is the key equipment for the production, such a equipment can use various raw material to make pellet fuel, such as peanut shell, saw dust, corn stalk, etc.
  • Cooling. The hot peanut shell pellet are easily broken, so after the pellet out from the pellet mill, should take them into the cooling system. Until the peanut shell pellet have the normal temperature can bag them and be put in storage.

Application of peanut shell pellet

  • Used for daily life. Because of the high uses ratio, and the feature of easily storage and transport, peanut shell pellet can used for our daily life, like household heating, cooking. It used safety and wholesomely.
  • Biomass industrial stove. As the main fuel for the biomass industrial stove, peanut shell pellet mill can replace the coal, petroleum and gas to protect environment, solve the environmental problem. In addition, peanut shell pellet have not corrosion element, that can not corrode the stove. So use the peanut shell pellet can extend the industrial stove’s service life.
