Screw pressing line for Pini-kay briquettes production.

Bio-fuel production is a promising direction, since it is associated with the use of renewable resources for energy production.

Equipment is designed for production of briquettes (without binders), which have wide application;

• As a solid fuel in boilers, kilns, furnaces, etc.
• As raw materials for producing charcoal of a new generation by the pyrolysis of briquette in charcoal kilns.

The obtained briquettes Pini-Kay in the production process correspond to all European standards and do not require Certification.

Raw material for briquettes production

Also the briquette can be obtained from: the husk of sunflower, rice, buckwheat and other grains; straw, bulrush; walnut shells, olive pits; lignin, peat and other biomass.

The possible shapes of briquette 

Characteristics of briquettes produced by press:

• International Pini-kay standard.
• The length 200 - 250 mm.
• The diameter of the hole - 10 mm.
• Calorific capacity: about 5000 kcal/kg
• Humidity: up to 8%.
• Ash content: up to 1.2%.

BRIEF DESCRIPTION OF THE BRIQUETTING PROCESS

Raw material for briquetting is loaded into crushing machine 1, where primary crushing takes place. Then raw material is fed into separating drum 2, where it is calibrated in sizes. Calibrated raw material is fed into the storage hopper 3, equipped with blades for mixing and then it is fed into a combined dryer 5 (drum dryer with characteristics of aerodynamic dryer). After drying raw material is crushed in hammer crusher 6 to a fraction less than 1 mm, which is optimal for briquetting. Then it is fed into the storage hopper 7, which is also equipped with blades, and passes through aerodynamic dryer 8, which remove the remaining moisture. After that, the raw material is captured by the cyclone 10 and is accumulated in separate feeding hopper 9. Then raw material is fed for the briquetting by screw extruder 11 due to release of lignin during heating of raw materials. The formed briquette is fed into cooling chamber 12, where formed gases are gathered. The briquette is fed into feeding conveyor 13.

This equipment is perfect for production of new breed charcoal

Charcoa burning kiln is used to produce charcoal from pini-kay briquette.

Useful information:

• 400 kg of charcoal is produced from 1 ton of briquettes
• 1 ton of briquette charcoal is 4 times more expensive than usual pini-kay briquette
• Pini-kay briquette charcoal burns 2 times longer than usual charcoal
• Consumption of pini-kay briquette charcoal is 2 times lower than usual charcoal
• Charcoal  briquettes are in demand all year round all over the world
