Factory on manufacture of fuel pellets 1 ... 1,5 t/hour with chipper and grinder of rolled straw

Factory on manufacture of fuel pellets 1 ... 1,5 t/hour with chipper and grinder of rolled straw

Factory of such type can produce granules from almost all natural raw materials (bio mass). Logs and half logs and other wood wastes are supplied to the chopping machine (22) with the help of the transporter (23). From the chopping machine chips go the transporter (24) and then to the mechanized storage “moving floor” (1).
Rolled straw goes first to the delivery tray (26), then goes to the grinder for rolled straw. Grinded straw is transferred by pneumonic transporter to the mechanized storage “moving floor” (1). Fine raw materials are supplied by transport (or loader) and strewed on mechanized storage “moving floor” (1). Stockers of “moving floor” possess hydraulic engine and provide reciprocating movements. Wings of stockers are wedge-shaped and in the process of stockers’ movement raw materials are supplied to chain transporter (2) and then to disc separator (3) at controlled speed. In disc separator raw materials are spared form stones, roots etc that go to transportable container (not shown on the scheme), and the raw materials go to loading section of Grinding and drying machine (4). It also gathers combustion products from heat generator (4) and collects cold air from emergency pipe (6) (is not included into the complex of spare parts). First of all combustion products and cold air are mixed in automatically regulated proportion that provide substantial temperature of the coolant. Then the coolant is mixed with wet raw material and goes to Grinding and drying machine (4) where raw materials are grinded and dried going in the flow of the coolant up to dynamic classifier placed at the head of Grinding and drying machine (4). Dynamic classifier receives frequency from control panel (20) and conduct small and dry raw materials and returns big parts to the rotor, then this process repeats till the necessary wetness and degree of grinding is gained (details). Grinded and dried raw materials (hereinafter referred to as “flour”) go to sediment cyclone (8) at the expense of discharging created by exhauster. In the cyclone flour sediments due to centrifugal force and go down, worn out coolant is thrown out through the pipe (19). Form the cyclone flour goes to screw or chain transporter (9) through seal leg and then goes to granulator bunker (10). Inside the bunker there is a mechanism protecting flour from caking. Screw feed with regulated speed of supply transfer flour from the bunker to the pressure mixer. Water or steam is also sullied here. The mixer provides conditioning of the product that is reaching the level of flour wetness necessary for granulating process. From the mixer wet flour goes to pressure granulator (11) through divider of tramp iron. In pressure camera flour is pulled between turning matrix and pressing rolls and pushed through radial holes of matrix where the process of making granules goes on under big pressure. Granules pushed from the holes meet the immovable knife and are cut. Cut granules fall down and transferred out of pressure with the help of a sleeve. Granules possess high temperature after coming from pressure and are fragile that’s why they are transported by noria (12) to refrigerating column (13). Here the cyclone ventilator (16) inhales air through the layer of granules thus cooling them and inhaling part of not granulated flour into the cyclone. In the process of cooling wetness of granules decreases due to evaporation and granules are subject to physical and chemical changes. As a result they receive the necessary solidity, wetness and temperature. As a refrigerating column fills out the granules are transferred to the sorting section (14) where conditioned granules are separated from chips. Granules are unloaded through unloading necktube and are supplied to the noria of ready products (15). Chips are inhaled to the cyclone (16) and sent together with flour to the secondary pressure. Noria of the ready products transfers the granules to the bunker of ready production (17). Under the bunker there are electronic scales (18), the bunker’s stands possess crooks for Big-Bags. Filled Big-Bags are transported by loader of hydraulic machine to the storage of ready production. Heat generator in this type of construction can be filled with fuel either in manual way or in automatic way – from fuel bunker (7).filling of fuel bunker goes automatically due to return of part of flour from sediment cyclone (8) by the system of pneumonic transport. There is a possibility to fill fuel bunker by additional transport from raw materials storage or separate fuel storages (not shown at the scheme).
