Small-scale pellet lines
Basic information
We offer a small-scale pellet line of Czech production with a guaranteed output of 200 kg / hour. As a condition for the production of quality pellets, the input moisture of the raw material (sawdust, wood, peat, ...) must be between 13 and 15%. The advantage of the small-scale pellet line is easy serviceability and minimal demands on the production space. The goal of the development was price and capacity availability for small agricultural, timber and joinery operations. The construction of the pelletizing line enables easy handling and transportation.

Intake of raw material
Receipt of sawdust into the hopper is handled manually in the base assembly. Rotary pickup system (0.55 kW) in the container prevents clogging of raw material and allow its complete emptying. The raw material passes into the tubular screw conveyor ∅ 150 mm (0.75 kW) from the container, which is controlled by a frequency inverter. Using a screw conveyor, the feedstock is transferred to a vibratory dispenser equipped with a magnetic separator to remove all metallic impurities before entering the annular granulator.
Pressing of raw material
Due to the influence of the frequency converter, the raw material is continuously fed into the pressing unit of the ring granulator PR15 (main motor 15 kW). The granulator gearbox is filled with synthetic oil as a lifetime filling (approx. 20,000 hours). The ring granulator is equipped with a basic coarse separation of the swarf from the finished pellets. The manufacturer does not recommend reverse operation of the granulator!
Pellet cooling
From the ring granulator PR15 the finished pellets enter the cooler. In the central part of the cooler there is a capacitive sensor which, together with the electronics in the technology cabinet, controls the entire pellet cooling process. The cooler is equipped with a grate with a pneumatic piston that opens and closes the cooler. When the cooler is opened, batches of finished pellets are cyclically discharged into the lower hopper.
Pellet packaging
A 2.5 m (1.1 kW) conveyor belt is placed under the cooler hopper for conveying the pellets to the selected container mounted in the support stand. The hot air is driven via a fan to the end aspirator, which removes the hot air from the technology.
Electrical equipment
The electrical switchboard is used to control and manage the line. It contains controls for all motors in the technology, including an ammeter with granulator load control. Beyond the automatic operation, the discharge of the cooling equipment and the conveyor belt can be controlled independently. Signalling lights inform about the operation or possible failure of the granulation.
Transportation and assembly
Nakládku lze uskutečnit vysokozdvižným vozíkem nebo vozidlem s hydraulickou rukou. Pro tento účel je rám linky opatřen oky pro manipulaci. Technologie bude připravena pro přepravu ve dvousamostatných nákladových kusech. První část linky má přepravní rozměry 4,5 m x 1,8 m x 2,4 m, druhý kus (aspirace) je v rozloženém stavu připevněn k EUR paletě o rozměru 120 cm x 80 cm.U koncového zákazníka dojde ke kompletaci obou kusů, ukotvení technologie ve čtyřech bodech k betonové podlaze, seřízení a proškolení obsluhy. Elektrospecialista připojí technologii k hlavnímu přívodu elektrické energie.Pro oblast Ukrajiny je tato činnost vykonávánanaší místní servisní organizací.
