small biomass pellet plant

When you want to make pellets, you may need some equipment like hammer mill, material mixer, screw feeder, pellet machine, vibrating screen, etc. However, for the small scale wood pellet manufaturers, it is not an easy task to combine these facilities all together and place them in a limited space.
Luckily, GEMCO has developed a new type integrated small biomass pellet plant for making biomass materials like sawdust, wood chips, straw, hay, sunflower husk, etc. into pellets fuel.

The MPL300 small biomass pellet plant is a complete pellet production line that includes hammer mill, cyclone separator, material mixing & storage bin, screw feeder, ZLSP-300B R-type pellet machine, water tank, vibrating screen, bucket conveyor, foundation frame and electric cabinet.

Detailed information of small mobile pellet plant main parts

Ⅰ Crushing system
Hammer Mill:

It's with 15 hammer blades, by changing the different position of the blades, it's suitable for crushing woody or biomass or forage material with size less than 20 mm (diameter), the size of the output crushed material can reach diameter 3-5mm.

Pneumatic Conveying Unit:

This unit includes one 2.2kw air blower, wind pipeline and cyclone separator. It will transport the crushed material into bin for mixing and storage. It's connected with vibrating screen and bucket conveyor with semitransparent soft pipes to cool the pellets, and collect the powder and dust.

ⅡMaterial Mixing, Storage & Conveying Section
Material Mixing, Storage Bin:

It's with 1m3 volume, its shell is made of 2.5 mm steel plate. There are two portholes on both sides for monitoring and observation. Four paddle type mixers is driven by one 0.75KW motor. The highest material level for this bin is at 800mm from the bottom.

Screw conveyor:

The input port for mixed material is at the bottom of the bin. It's 112mm in diameter, 1023 mm long. It is to feed the mixed material into the pellet mill, and is driven by frequency conversion speed controlled motor, 0.18 KW, frequency conversion range is 30~60 Hz.

Ⅲ Pelletizing Section
Pellet Machine:

This ZLSP-300B R-type pellet machine makes 0.4 ton wood pellets per hour by using pure sawdust. The water adding system is connected and available to adjust the moisture content of the mixed material. We can make 6, 8 mm pellets (diam.).

Water Tank

This tank can carry 100 L water. The water pump is at 24V, capacity : 5L/min, water discharge pressure: 8.5kg, flow meter capacity: 0.2-2GPM

Ⅳ Sieving & Pellet Conveying Section
Vibrating sieve:

3.5*3.5mm Mesh, with 0.37KW power. The size of the mesh can be changed according to your requirements. One φ45mm soft pipes is connect to collect the powder and dust.

Scraper conveyor

It's driven by chain, the scraper size is at 145mm. The size for single section is 2436*437*484 mm. The length and height of this conveyor can be extended by adding and connecting one extra section. There are five positioning joints at the end of the conveyor, you can adjust the height and angle of the conveyor easily. Two φ100mm soft pipes is connect to cool the pellets.
