4-6tph Palm waste biomass pelleting line

Taking palm waste as raw material, it was solidified and extruded into high density pellet fuel through pretreatment and processing. It can save energy and reduce emissions, and has good economic and social benefits. It can be widely used in biomass power plant, biomass steam boiler, domestic fireplace, drying stove and biomass gasifier, etc. It is an efficient and clean renewable energy.

Jiangsu Liangyou Zhengda Co., Ltd. specializes in the production of complete biomass pellet fuel forming equipment, can provide customers with logs, wood chips, shavings and other raw materials of biomass pellet production line; Biomass granulation production line with building template, woodworking scrap and other raw materials; Complete biomass pelleting production line with corn straw, wheat straw and straw grass as raw materials; Complete biomass pelleting production line with fruit shell, fruit residue and palm as raw materials; Complete biomass pelleting production line with crop waste, sludge, coal and other raw materials, tailor-made complete equipment solutions for customers, to meet the different needs of customers.

Now take the production line project of 4-6tph Palm waste granulation production line as a case, according to the technological process and each section to do the following introduction and explanation.


4-6tph Palm waste biomass pelleting line 

Raw material:

There are mainly palm shell, palm leaf, and palm fruit channeling EFB,etc.

Flow process brief introduction

Palm waste is coarsely crushed through a drum beater and then cut into fine powder through a special palm cutter. Then, after the pre-cleaner, the raw material with 50% moisture entering the 3 layers drum dryer, is dried into about 15% moisture. and finally is pelleted. The diameter of the finished product is 6-10mm, which is optional. After the pelleting and cooling, it is packed into 20-50kg/bag by the small bag packing scale which is convenient to transport and sell. Palm pelleting complete project with 5tph, the total power is be around 890kw. The workshop covers an area of 2400 ㎡, contains raw material and finished products warehouse; The design of the whole line is compact, reasonable, meets the requirements of environmental protection, and can be customized according to customer requirements.

Craft features and process introduction

Grinding process:

The palm shell, palm leaf, palm fruit channeling go through the drum beater first, the long fiber shape palm silk is roughly grind ed into 5-10cm long. Then cut into the palm grass powder by the special palm cutter. After grinding, the material is transported by the fan's negative pressure suction air pressure, with high output, low pollution and effective inhibition of dust pollution in the workshop.

cleaning process:

The purpose of the complete palm-pelleting project in the cleaning process is to clean up the major impurities in the raw materials, so as to avoid the failure or damage of the mechanical equipment and conveying equipment in the next process.

Cleaning equipment: MCY160*300, power 3kw, design output: 6tph

Drying process: 

Three layer drum dryer. After drying, the moisture content of sawdust is around 13-18%.

Drying equipment: LYHG50, roller diameter of 3m, length of 11.6m, power of 19kw, designed output 5tph (original moisture of raw material is 50%).

Pelleting process:

The diameter of biomass particles is 6-10mm, which is optional. And the biomass particles have the characteristics of high calorific value, no pollution and low ash content, which can be widely used in biomass power plants, biomass steam boilers, household fireplaces, drying furnaces and biomass gasifier, etc.

Granulating equipment(5sets): MZLH420, host power: 90kw, power of mandatory feeder: 0.75kw, designed output: 1t/set

Cooling and bagging process:

To reduce particle temperature and decrease grain moisture. The pellet after cooler is not higher than room temperature 5 ℃, pellet moisture after cooled is around 8-10%, particle density 650-750 kg/m3.

The bagging scale is according to the customer's local sales needs, the appropriate packing scale is selected to facilitate the customer to sell products. There are usually two specifications: small bag and ton bag. 20-50kg/bag for small bags, 500-1000kg/bag for ton bags.

Cooling equipment: SKLB4, cooling room volume:4m3, Design output 5-6tph.

Packing equipment: SDBLY-K, packing range: 20-50kg/ bag, 3-5 bags/min.

According to the needs of different customers, the scheme can be optimized:

1. If necessary, buffer bins can be added between each section to replace the storage yard. The advantage is that it can improve the automation degree of production line and reduce dust pollution in the workshop; The disadvantage is that it will increase the construction cost of the production line, and because the bulk density of materials after crushing is very light, it is easy to bridge in the bins and material does not drop.

2. f the moisture content of the raw material is not higher than 15%, you can not use the dryer. It can be pelleted directly after grinding; If more than 15% but less than 20%, you can consider mixing dry materials with wet materials, making water neutralization and reduction, and then granulation;

3. The packaging equipment can be adjusted according to customers' requirements for finished product packaging. It can also be stored in bulk or stored into silos.
