LU АS-5-22000 EURO pellets production line. Productivity - 22 000 tons/year


1. Parts and general information

LU АS- 5-22000 (EURO), mini plant, equipped with all necessary machine can operate using both dry and wet raw materials and is environmental-friendly.

Purpose and productivity
The manufacturing line is intended for production of no less than 22000 tons.of europellets Observance of process discipline provides the conformity to European standards
By the customer’s order we can produce hexagonal or octahedron Euro-pellets.
Crossing 50 mm, smoke-deflecting channel (diameter 15 mm), the length 450, 600, 750 mm, by the customer’s order.
Heat-emission of the pellets doesn’t depend on our machines, it totally depends on process discipline and raw materials’ characteristics. As a rule it is no less then 5000 kcal

Production technology doesn’t include adding of viscous additives to euro-pellets
The assembly of the line allows to increase its productivity by additional purchasing of some machines and their connection to the existing production cycle.

Raw materials
Annual production of 22 000  tons of euro-pellets requires about  30 000 -32 000m3 of initial raw materials  .
Raw materials consumption depends on moisture and dust contents
The water is removed by drying and raw materials lose up to 50% of its weight.
Transportation, drying and briquetting cause the dust burning out.
The losses are 15% and 3-4% at processing of peat and wood chips, respectively.
Bark, thin twigs, wood chips, saw dust, shavings, cotton stalks, corn, soy, canes, sun-flower stalks, hay, straw, cotton cake, cereal husk, sun-flower seed husks, etc serve as raw materials If you wish to use as raw materials the whole log wood, used furniture, the wood that remained after demolition and reconstruction of houses instead of agricultural and woodworking wastes, it will be necessary to complete the production line with two additional units. Mixing of two different organic substances (rice husks and natural sawdust, straw and corn stalks) doesn’t worsen the quality of Euro-pellet

Personnel and operation mode
Productivity of the equipment is considered for 16 hrs/day, 260 days/year.
One shift- 15-20 persons.
The duration of the shift – 8 hrs. According to standards, there should be two shifts/day
As the degree of automation is rather high, no considerable loading operations are required, the functions of the personnel are limited to control of the machine operations and collection of the spilled raw materials, so women can constitute up to 50% of the personnel.

Production areas
According to design, it is necessary to have production facilities as follows.
Open ground – raw materials warehouse – 6000 m 2
Raw materials preparation shop – 30m х 20m = 600 m2
Raw materials drying shop -20m х 25m = 500m2
pellet forming, cooling and packing shop 45m х 30m = 1350m2.
Warehouse 500 m2

Production process
Raw materials supply- Conveyor - Cutting of bales (e.g. barrels of cereal straws, diameter up to 1500 mm)- conveyor- shredding of raw materials up to 0,4 -0,7 mm,- conveyor- separation into large, off-grade raw materials, to be broken further and grade raw materials - removal of metals - lifting conveyor - feeding to drying units – feeding to oven - drying coiled pipes - cyclone after dropping the moisture in raw materials to - 8%–conveyor - storage tank - feeding hose - mixing heating lignin formation - outer hardening – cutting by standards – cooling- packing . 

The final product
Euro pellets made of twigs, sawdust  and agricultural wastes

Application
There is no demand in China for Europellets, they are in Europe (25 000 000), and the demand is forecast to double in 5 years.
The price (at the beginning of 2009) -130-140 Euro/ton.
They are widely used for house heating, food preparation. They are burned in individual boilers of cottages, some big power stations also use pellets.
In Europe 75% europellets are processes into charcoal or coke.
The sizes are adjustable, usual length is 500 mm, diameter 50 mm, smoke deflector is mm.
Moisture content of raw materials is 30-40%, for 1 ton of finished europellets 1,4 tons of raw materials is required.
