1-2TPH capacity new technology wood pellet manufacturing plant project in Indonesia

Region: Asia

In 2016, Indonesia's biofuel production surpassed Thailand for the first time, ranking first in Asia, an increase of 84.3% compared to 2015, making it the country with the fastest increase in biofuel production in the world. In the past ten years, with the economic recovery, Indonesia's energy consumption is growing rapidly, and accelerating the development of renewable energy has become an important task of the Indonesian government.

The Indonesia client has a abundant of source of wooden waster material. Day after day, how to dispose with these material in a more profitable way becomes a burning issue. So he invested his first good quality wood pellet plant with 1-2tph capacity in 2017. The investment was around 400000USD. In his 1-2 ton per hour new design biomass fuel wood pellet production line, logs and wood chips from forest harvest, offcuts and saw dust from furniture factory are used as feedstock for making wood pellets. The moisture of wood logs is about 60%, and 18% for offcuts. The pellets are sold to local pellets retailers. By and large, pellets are finally used for burning boiler for industrial purpose.  

In order to make wood pellets from the mixed raw material, my client bought 2 sets of ring die wood waste pellet mills and other equipments from RICHI, a China wood pellet production line supplier with high reputation in many coutries. The easy to handle 1-2t/h whole wood pelletizing line is consisted of raw material resizing equipments, such as log cutter, good quality wood chipper shredder and wood hammer mill crusher(the wood logs and offcuts can be resized properly before pelletizing by these machines). professional manufactured wood chip dryer, MZLH420 wood pellet pressing machine, screener, pellet cooler, packing machines, etc.During the test,biomass wood chips rotary drum dryer, wood pelletizer machine and other parts were working properly after some tweaks, producing quality wood pellets. During the first few testing day, the client delivered 2 trucks of finished pellets (approximately 15-20 tons of pellets) each day.

Complete production process deaign of this 1-2 ton per hour customized biomass wood pellet line project in Indonesia

(1)Raw materials preparation

The raw materials of this wood pellet processing line project with 1-2tph capacity is wood log from wood dealers and off-cuts and sawdust form furniture factory. The moisture content of the wood log is high up to 60% percent which needs to be chipped and then dried. A hot sale wood chipper crusher and high quality wood sawdust dryer machine in the wood pellet production factory project are used for this purpose.For wood logs, a wood log cutter is needed to face this challenge.  

(2)Wood cutter

The cut logs will be further processed by a wood hammer mill for wood chips and a wood crusher machine for making sawdust. The fined particles will be dried until the moisture content is around 15%. When the fined materials are ready, they will be conveyed into the wood pellet making machines.  

(3)Pelletizing

A ring die good stability wood pellet mill is typically used for high return 1-2tph wood pellet making line. It is well-known for longer working life and lower investment. Here are some tips while operating biomass fuel wood pellet mill:    

①Proper adjusting and periodical maintenance of rollers which should be checked after every 10 hours, every 48 working hours, demounting and adjusting if necessary. 

②Proper training is required for new wood pelleting equipment operators. 

③When unexpected noise happens inside the press chamber, try adjusting relative movement between rollers and dies.

(4)Packaging and storage of wood pellets

In this reasonable design new wood pellet production plant project, the wood fuel pellets are packed in 15kg bags. An automatic wood pellet packaging machine and scale are equipped. When you store wood pellets in separate bags, follow these rules:  

①Wood pellets should be kept from moisture and humidity, which may rotten the pellets. And it's best to place the wood pellet bags indoors, such as, garage and basement, etc.

②If the pellets have to be placed outdoor, the shelter or cover is necessary to keep them dry. It would be better to keep the wood pellets bags off the ground by stacking them on pallets. And while stacking the pellets bags, attention is required to the holes on the bags which need to be repaired by water proof tapes, such as duct tape. The stacked pellets bags should be properly covered and fastened to keep them dry and safe from being broken.

③The pellets should be kept from the direct sunlight, which may higher the storage temperature and increase the chance of fine percentage.

④The pellets should be kept in a well ventilated place because monoxide gas may be released from the pellets stored, especially in a warm environments. Be aware of the CO poisoning.
