4-6tph Palm waste biomass pelleting line

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.
