Using the pneumatic spade (1) an auxiliary worker loads raw material into the processing bin (2). The required rarefaction is produced by dust fan (3) mounted in the upper part of the processing bin (2). Separation of the feed from the air flow takes place in discharger (4), in the bottom of which the rotary valve (5) is located. The feed entering the processing bin (2) is captured by blades of the auger conveyor-feeder (6) and then fed into S.A.M.P.O. 2012 mill-heater (7) where it is milled and heat treated. If required, for example, if the feed is too dry, water from the supply tank can be delivered to the body of the mill-heater (7) through special nozzles. Water goes into the mill-heater (7) by means of a dosing pump with the flow rate controlled by a line operator.

After leaving the mill-heater (7), the hot moulding material enters the press-granulator (8) where it is compacted by rotating rollers. The length of the pellets is controlled by the position of the truncating stopper.

When the line is in the ‘Auto’ mode, the volume of the feed sent into the mill-heater (7) is controlled by the Balance automatic control unit installed in the remote control panel (9). If the permissible load on the electric motor of the mill-heater (7) or press-granulator (8) is exceeded, the Balance automatic control unit automatically reduces the speed of the auger conveyor-feeder (6), and when the load is reduced the unit independently increases the speed. When the rotation speed of the auger conveyor-feeder (6) is reduced, the amount of raw material fed into the mill-heater (7) is reduced, and increased when the speed increases.

Formed pellets from the press-granulator (8) go onto the grid of the Kreiss inertia conveyor (10) connected via a flexible hose (11) to the pneumatic system of the line. Poor compressed pellet particles fall through the conveyor grid (10) and under vacuum enter the cyclone (4), and from there through the rotary valve (5) back to the processing bin (2). As pellets move through the Kreiss conveyor grid (8) they are cooled by the air sucked into the system by fan dust (3) from the production area.

During the operation of the line the temperature of the moulding material at the outlet of the mill-heater (7) can go up to 80°C. The temperature of the cooling liquid in the body of the mill-heater (7) can rise up to 45-50°C.

To achieve best granulation performance the operator during the process can change the milling fineness and temperature with the help of the control handles (12) mounted on the belt guard of the mill-heater (7).

The dust from the granulation process is trapped by elbow air ducts and through the flexible hose (13) connected to the pneumatic system is transported to the cyclone (4) and then to the processing bin (2).

To service the mill chamber of the mill-heater (7) and replace wear-prone elements of the rotor-impeller the moving parts of the system are mounted on the wheel assembly (14) allowing for their movement on special guiding elements of the frame.

ВAn option to produce ENplus standard fuel pellets from wet plant material. The Scarabey® line kinetic drying of the feed occurs in the process of milling at a relatively low temperature of the heat-transfer medium, which almost completely eliminates risk of fire.

Safe drying of wet materials without burning any fuel is the most impressive but not the only feature of the Scarabey ^® line. The short list of its major advantages will make you believe it:

The All-inclusive Process principle: Little things matter in pellets production! Coordinated operation of the mill, of the steam treatment unit and the feeder is no less important than the press-granulator capacity. The production volume, the quality of the fuel pellets, and the operating life of consumables are directly dependent on how well the raw material is prepared for pelletizing. For this reason the Scarabey^® line is equipped not only with the mill and press-granulator but also a full range of other necessary equipment. In particular, before granulation, the conditioning of the wood pulp is performed not only by wetting with water but also by complete treatment with the steam produced without a steam generator;

High milling capacity: the Scarabey^® line is equipped with a combined S.А.М.P.O. 2012 mill-heater capable of efficiently milling a variety of plant materials, whereby the dimensions of the original material and particles produced after milling differ by more than 200 times;

Fewer requirements for raw material: some types of raw plant materials are poorly amenable to pelletizing because of the too low content of lignin. However, it is also well known that if plant waste is milled to powder, quality pellets can be produced from raw materials with a low content of lignin, whereby the press-granulator performance typically increases by 20-25%;

All the critical operations are automatic controlled: The Balance automatic control unit provides: start and stop of the Scarabey^® equipment in the correct sequence, control of abnormal modes, adjustment of the feed depending on the mill and press-granulator motor load;

Intellectual property: the technology and equipment for granulation of raw plant materials were developed by the TECHPRIBOR PLANT experts (Russia). Unique engineering solutions implemented in the Scarabey® line are protected by Russian patents Nos. 2462313, 110661, 109420, 80773;

TECHPRIBOR PLANT’s philosophy: cooperation with customers does not end with the shipment of equipment!

We know not at second hand the needs of production and, therefore, do everything possible to minimize downtime in any situations.

The manufactured Scarabey^® lines are provided with a constantly resupplied spare parts stock and consumables.

Any required parts are all time available at TECHPRIBOR PLANT’s supply warehouse.
