1-2 T/H Sawdust Wood Pellet Production Line in Italy

Italy is a net importer of wood pellets. Wood pellets are mainly imported from countries such as Germany, Bosnia and Herzegovina, Slovenia, Croatia, Poland, Lithuania, Romania, France, Russia, Czech Republic, Slovakia, Serbia, Bulgaria, Latvia, Estonia and Egypt.

Wood pellets in Italy are mainly used for heating small-scale private homes and industrial boilers. Around 96% of Italian pellet consumption comes from these heating industries, with the majority of pellets delivered in bags.

Bulk pellets up to 20,000 tons are transported by silo trucks. The report pointed out that its domestic production can only meet less than 30% of domestic pellet demand, and more than 70% of wood pellets need to be met through imports.

If there is demand, there must be a market. Currently, more and more Italian investors are interested in entering the wood pellet processing industry. Especially those industries related to wood pellet processing, such as furniture factories, sawdust factories, wood chip factories, etc.

These investors with raw material resources have also noticed the field of wood pellet processing and regarded wood pellet processing as a new business for their expansion.

The client of this 1-2 t/h sawdust pellet production line project is a furniture factory from Italy, which has abundant raw materials. In order to make full use of these processing residues and expand business channels, the Italian customer decided to invest US$80,000 to build this "annual biomass pellet fuel processing project of 4,500 tons." It is worth mentioning that this customer is an old friend of RICHI. Because in 2021, the customer purchased a wood chip dryer from RICHI to dry the wood scraps from the furniture factory, and then sell these wood chips and sawdust.

• Project area: The factory covers an area of 350m2, which is construction land
• Project investment: 80,000 USD
• Raw materials: pure sawdust
• Construction period: 1 month
• Annual power consumption: 50,000 kWh, powered by the local power grid
• Labor capacity: 5 people
• Working system: Production implements an 8-hour day shift system, no production at night, and annual working hours are 300 days

This 1-2 t/h sawdust wood pellet production line in Italy project uses the existing factory building and purchases a total of 12 main production equipment such as pellet machines, distributors, hoppers, conveyor belts, and air pumps. The specific construction content is shown in the table below:

The main production equipment of this 1-2 t/h sawdust wood pellet production line in Italy project is shown in the table below:

This is a sawdust pellet production line, the raw material is only sawdust. The consumption of main raw and auxiliary materials for this project is shown in the table below:

Brief description of process flow:

1. Unloading:
   The raw and auxiliary materials used by the company are mainly sawdust, which comes from the customer's furniture factory. The crushing degree and dryness are both qualified. No further crushing and drying are required.
   The moisture content of the sawdust is 6%-12%. In between, the particle size is about 3mm-20mm. The sawdust is directly placed in the factory building, and unloading is completed in a closed workshop.
2. Granulation:
   The raw materials are lifted by the belt conveyor, sealed and transported to the warehouse to be granulated, and then formed in the wood pellet mill. No additives are required during the granulation process.
   The raw materials enter the wood granulator from the granulator bin. Through electric heating, the temperature of the powder can reach 80°C to 90°C.
   The extruded pellet fuel is continuously squeezed out to the outer end of the die hole, and the cutter cuts the molded pellets into required pieces. length, the final formed granules flow out of the sawdust pellet press and fall into the product conveyor.
3. Screening and warehousing:
   The cooled sawdust pellets enter the rotary grading screen. The sawdust pellets that meet the requirements enter the finished product bin through the conveyor.
   The sawdust pellets that do not meet the requirements fall into the lower layer of the screen and are discharged before entering the finished product bin, reused in the granulation process.
   Qualified sawdust pellets fall into the finished product bin. The bottom of the finished product bin is a funnel-shaped outlet, which is pneumatically discharged.
   The finished product can be directly dropped into the packaging bag, and can be sold after being packed with a baler. The formed sawdust pellets have been pressed and compacted, and basically no dust is generated during the bagging process.

• Waste gas: The waste gas generated by the 1-2 t/h sawdust wood pellet production line in Italy project is mainly the waste gas generated by unloading, transportation, granulation, and screening. The main pollutant is particulate matter.
• Wastewater: No production wastewater is generated in the project. The wastewater is mainly employee toilet wastewater. The main pollutants are COD, SS, and ammonia nitrogen.
• Noise: The main noise sources of the project are pellet machines, material distributors, hoppers, conveyor belts, air pumps, etc. The noise level is 75~85dB(A).
• Solid waste: The solid waste generated by the project mainly includes unqualified products generated during the production process, dust removal ash, and domestic waste generated by employees’ lives. According to the "Catalogue of Hazardous Wastes", there are no hazardous wastes in this project and they are all general solid wastes.

In response to the above pollution, the environmental protection measures adopted by this 1-2 t/h sawdust wood pellet production line in Italy project are as follows:

Your funds and budget are the first things to consider in your sawdust pellet production line in Italy construction. Your budget tends to tell the scale of the wood pellet line regarding large size or small scale. In case you do not have sufficient funds, then consider lowering your capacity.

Consequently, you can get even lower some relatively unimportant equipment. However, in cutting cost, it is never advisable to substitute the necessary equipment with low price and low-quality ones. You might end up regretting the move.

• Your workshop is another thing that you need to consider in designing a wood pellet production line in Italy. In fact, the funds available to you will tend to determine your workshop size in that the higher the resources, the bigger the workshop you can build.
• Again, consider having your wood pellet plan design near your raw material to ensure that you cut the cost of raw material transportation.
• Investigate the marketing channels and determine the type of feed to be produced. Including feed quality and output requirements, and determining the formula for feed processing.
• Consequently, if you have a workshop, determine its height, width, and length. Consider then designing your wood pellets depending on your workshop size to ensure it is enough to lace the equipment.

To keep the best of the wood pellet production line design, the following measures need to be included primarily to the wood pellet raw materials:

• The raw material size of the wood pellet production plant is required to be readily produced in high-grade pellet status hence ensure you give essential attention and concern to the raw material size.
• Ensure the cleanliness of the raw materials. There is fact in the statement, the cleaner the raw material then definitely the high the effectiveness of the wood pellet plant production.
• Moisture is another key feature to ensure your raw material. Ensure that then your raw material is not too moist or less. Too much humidity can alter the pellet quality and result in more energy consumption and importantly wear out of equipment. Ensure that the moisture is between 8-15 %.
• Hardness is another issue to consider for your raw materials. Ensure that they are not too hard to ensure easy making process of the pellets and also avoid damaging the spare parts.
• Ensure that your sawdust biomass pellet plant design raw materials are highly viscous so as they can easily adhere to the inside part of the pellet mill. Failure this, then the production capacity will be reduced while also altering the normal operation of biomass wood sawdust pellet mill.
• About the raw material, the density should be high to ensure that they a more significant capacity of the wood pellet mill.
