Pellet making and Briquette making of Carbon from Pyrolysis process of Scrap Tyre / old tire to produce oil

The pellet making of fine carbon (powder form) from scrap tyre pyrolysis plant (oil production) is slightly more difficult than production of pellet from coal or charcoal. The oil content in the carbon powder is one of the factors.
Normally oil content in the carbon powder should not be higher than 2-3%, otherwise binder will be required. In case that binder is required, the mixing of fine carbon powder and binder dispersion are the key to the success of pellet production.
Common problems with the pellet making from carbon powder from pyrolysis of tire are dispersion, high oil content and feeding of powder into pelletizer (difficult to feed). The design of machine must take these factors into account.

Concerning the briquette making of fine carbon powder by screw press type machine, it is more difficult and has more factors to the success of the briquetting process. The main trouble is the heat generated by screw-press type machine will cause the change of powder’s characteristics (soften). Typically, the briquette made from screw-press type machine is not very high in density so it can be used as fuel for starting up the operation of the pyrolysis process (not very good if you want to sell them as briquette).

Coal Pellet - Thai Sumi

Coal pellet making machine & system

Coal Pellet machine (30 HP, TWP-03FCP Type) can pelletize about 500-600 kg/hr, depending on the size and moisture content of coal. The pellet diameter can be adjusted from 6 mm. to 15 mm. (need TWP-04 or higher model). Length can be adjusted by length adjusted unit, installed at the machine.
Coal pellet can be sold at higher price than undersize coal or fine coal. Higher moisture content in the pellet is acceptable in most cases (water may be needed for moisture content adjustment for pelletization process).

สเปคถ่านขาวและถ่านดำ (White Charcoal / Black Charcoal Spec)

ข้างล่างนี้เป็นตัวอย่างสเปคของถ่านขาวและถ่านดำครับ สงสัยอะไรเพิ่มเติมก็โพสท์ถามไว้ได้ครับ จะรีบตอบ
