It is worth mentioning that we have currently exported multiple biomass pellet production line projects to India, including wood pellet production lines, bagasse pellet production lines, and bamboo pellet production lines. If you are interested in our projects, please contact us for details!

Main construction content and scale

This 4 t/h napier grass pellet production line in India project covers an area of 10,000m2 and has a total construction area of 1,700m2. It is mainly divided into production workshops, warehouses, comprehensive office buildings, etc. After the project is fully completed, it can produce 10,000t/a of biomass pellets.

The main construction contents of the project are shown in the table below:

Raw and auxiliary materials and energy consumption

The main raw materials required for the production of this 4 t/h napier grass pellet production line in India project are napier grass, straw, rice straw, rice husk and other solid waste from crops. The energy consumption of main raw and auxiliary materials is shown in the table below:

General layout of 4 t/h napier grass pellet production line in India

The factory area is generally divided into two parts. The north side is the production area, which houses a straw biomass fuel processing workshop and a warehouse. The south side is the office and living area, with an office.

The overall plan design of the 4 t/h napier grass pellet production line in India project combines the natural conditions of the factory area such as topography, geology, hydrology, meteorology, etc., and comprehensively and reasonably arranges the factory buildings and transportation lines.

The building layout is compact, the transportation is convenient, and the management is convenient, which is conducive to improving the production efficiency of the enterprise and reducing transportation costs. . In summary, the layout of the proposed project is reasonable.

Process flow of 4 t/h napier grass pellet production line in India

1. Loading and unloading
   Wastes such as napier grass, straw, hay, and straw brought by cars from the surrounding areas are loaded, unloaded, and stacked in the warehouse.
2. Crushing
   The raw materials are crushed according to the process requirements, and the crushed raw materials are less than 5mm. The dust generated by this process is processed through a bag dust collector, and the dust generated is recycled.
3. Pelleting
   The biomass straw elephant grass pellet machine is a key equipment in the grass pellet production line. According to customer needs, the biomass pelletizer using ring molds of different sizes is adjusted.
   The raw material contains a certain amount of lignin and cellulose, and the lignin is the structural monomer in the material. It is a polymer compound. It has the function of strengthening cell walls and binding cellulose. Lignin is amorphous, and its main part is insoluble in any solvent at room temperature.
   It has no melting point, but has a softening point. When the temperature reaches a certain value, the lignin softens and the bonding force increases. Under a certain pressure, the cellulose molecular groups are dislocated, deformed, and extended.
   The adjacent biomass particles inside are toothed to each other, reassembled, and pressed into shape. The temperature during the granulation process should be controlled at 80-100 degrees Celsius, and the biomass pellet mill is sealed.
4. Conveying cooling
   The temperature of the elephant grass fuel at the outlet of the granulator is 80-90 degrees Celsius. The generated biomass pellets are sealed and sent to the cache silo through the conveyor belt. During the transportation process, the elephant grass pellets are naturally cooled.
5. Packing and warehousing
   The cooled straw napier grass pellets are packaged and stored in storage for sale.

Environmental protection measures

Exhaust gas

During the operation of this 4 t/h napier grass pellet production line in India project, the exhaust gas mainly comes from unloading, feeding dust, and crushing dust.

The conveying method of this project is closed conveying. The unloading dust generated during the unloading process of dust and raw materials to the workshop is unorganized. After the feeding dust is collected by the gas collection device and the crushed dust is processed by a set of bag dust removal device, it passes through a 15-meter Meter high exhaust pipe discharge.

In summary, the feed dust in this 4 t/h napier grass pellet production line in India project is collected by the gas collection device and the crushed dust is processed by a bag dust collector and then discharged through a 15-meter-high exhaust pipe.

The organized dust emission is 0.1t/a, and the emission rate is approximately The emission concentration is 0.04kg/h, the emission concentration is 5.21mg/m3, the unorganized emission of this project is about 0.07t/a, and the emission rate is about 0.03kg/h.

Noise

Noise mainly comes from mechanical noise generated by the operation of production equipment, fans and other equipment. Through engineering analysis, it can be seen that the noise source intensity is 60~84dB(A).

This 4 t/h napier grass pellet production line in India project reduces noise emissions by selecting low-noise equipment, rationally laying out equipment and installing it indoors, using vibration-absorbing foundations, and using the factory building as a sound barrier. The noise can be reduced by more than 20dB(A).

Solid waste

The solid waste generated during the operation period of this project includes dust collected by the dust collector and domestic garbage. Take the following pollution prevention and control measures:

• All dust collected by the dust collector is reused in the granulation process.
• Domestic waste shall be collected and transported uniformly by the municipal sanitation department.

After taking the above measures, 100% of the solid waste generated by this 4 t/h napier grass pellet production line in India project will be effectively disposed of and will not have an adverse impact on the surrounding environment.

In addition to this 4 t/h napier grass pellet production line in India, Richi Machinery also exported fish feed production line, shrimp feed production line, straw pellet production line, livestock and poultry feed production line and other projects to India.
