All pulp should be the same moisture content throughout. The more uniform moisture content and uniform pulp – the closer will be the pallet. Drying of raw materials occurs in the drying chambers drum specifically designed for biomass. For such equipment are particularly high demands on fire safety. Press granulation – is the main mechanism of production of fuel pellets. Of his work depends on the quality of products. In the granulator the process of forming pellets.

In the mixer granulator and moistened raw material in sufficient quantity is fed into the granulator. Movable rollers is forced through the holes in wood pulp into special shape matrix. After passing through the holes, the material shrinks, its density can reach 650 kg / m . Granulation of wood, unlike other biomass, requires special pressing force, a large force to push compactors channels. Therefore, the matrix and the rollers should be made of special wear-resistant steels.

Energy consumption ranges from 30 to 60 kWh per tonne. The heating of raw materials in presses up to 90 C, which makes raw materials especially fluid, and well pressed pellets. General characteristics of the production. The necessary electrical power equipment – up. 900 kW Core: – 5 – 8 people / change size: – Drying – preparatory area – approx. 900m – granulating area – approx. 900m – warehouse – is estimated at logistics capacity 2 tons / hour of pellets should be ok. 4 tons / hour of raw materials, which roughly corresponds to 16 m (bulk) Status of domestic and foreign market fuel granules. Today the market is growing at tremendous pace. Prices are rising constantly, and if it is signed the Kyoto Protocol, the demand for grain will be just great. To date, the main consumers are European countries. Typically, in countries such commodity market does not develop. In Russia, this market is already formed and will soon begin to actively grow. This is due to the fact that the pellets used for heating houses, and in Russia middle class is beginning to acquire out of town housing. Many already know that houses can be heated by fireplaces, boilers, wood waste, and are ready to buy equipment. And in Europe, a similar method heating homes – already a common thing, and all major supermarkets sell packaged granules of different sizes. So far, the highest demand – to 6-millimeter-thin pure pellets, since they are the main energy source for home fireplaces. The advantages of this fuel to all are obvious, and demand will only grow.
