2-2.5 T/H Wood Pellet Machine Germany Project

This is a complete set 2-2.5 t/h wood pellet machine Germany project.

2022.09.06, the customer sent a product inquiry:

“We are interessted in a 2-2.5T/H Complete Set Wood Pellet Line. We have 2.5 tons of dry spruce sawdust available per hour and would like to pellet them. Please send us an offer.”

2022.10.13, successfully signed the project, only took 1 month.

Project cost: nearly 120,000 USD.

It can be seen from the customer's consultation content that this is a simple design wood pellet production plant. Because the raw material used by the customer is dry spruce sawdust.

But in the end, the content of this wood pellet mill Germany project transaction includes a complete set of equipment such as wood crusher, wood pellet mixer, wood pellet mill, cooling machine, vibrating screen, and packing scale.

Because, in addition to dry spruce sawdust, the customer's raw materials also include wood shaving and other wood scraps.

According to the size of the raw materials provided by the customer, some of the raw materials are large in size. Although there is no need to configure a slicer, a wood sawdust making machine is still needed. In the end, we customized this 2-2.5 t/h wood pellet machine Germany project for the customer, and the process flow is as follows:

1. Cleaning and impurity removal: The raw materials of the project are shavings, sawdust, wood scraps, etc., and the raw materials are transported to the screening and cleaning equipment by a belt conveyor, and the impurities in the raw materials are cleaned by the screening equipment.
2. Pulverization: after the cleaning section, the raw materials with large size are pulverized. Because the particle size is large, it does not meet the granulation standard of the wood pellet mill granulator, and it is not easy to granulate. Use a pulverizer to further pulverize it. It is easier to process and handle.
3. Mixing: The customer needs to add binders such as starch, and mix the crushed raw materials.
4. Granulation: Put the pulverized raw materials into the wood pelletizer, driven by the motor, the raw materials are brought into the granulation bin, so that the lignin components in the raw materials are softened, and the bonding ability is enhanced. The high-strength extrusion of the ring die finally obtains high-density and high-hardness shaped biomass wood pellets.
5. Product inspection: Products that pass the inspection are put into storage and for sale.

(Note: Since the raw material used by the customer in the early stage is only dry spruce sawdust, the first order is only the equipment marked in blue in the picture, including mixing, granulating, cooling, screening, packaging and other equipment. Once other wood chip raw materials are in place, the customer will add the cleaning and shredding system.)

• The office area is located on the northeast side of the production plant, covering an area of 120m², for employees to work and rest.

In Europe, why do people in cooler climates choose wood pellet stoves? Because natural gas is more expensive than wood pellets. The application of wood pellets is becoming more common as a low-cost home heating option.

The use of wood pellets as fuel is widely used in domestic heating and power generation boilers, especially in Europe. The availability of raw materials such as wood and compacted wood chips and the low cost of production are the main factors behind the rapid growth in demand for wood pellets.

Richi Machinery has been actively engaged in the R&D and manufacturing of wood pellet machines to increase the efficiency of the wood pellet manufacturing process and gain a clear market advantage. The design of our wood pellet mills has always followed one core principle: high output with optimal fuel input.

In addition, for a wide range of biomass raw materials (such as straw, rice husk, palm shell, bamboo, etc.), customers need to process economically efficient pellet products from agricultural and forestry waste at low cost.

In response to the customer's pellet processing needs based on various raw materials, we will customize the pellet production line according to the customer's existing raw materials, with the purpose of producing biomass energy pellets with high calorific value.

From the perspective of environmental protection, the EU divides wood waste into three categories:

• Category A refers to the waste generated from forestry logging and wood product manufacturing, such as branches, roots, sawdust, scrap materials, etc. These wastes do not contain any pollutants. 
• Category B is waste building wood, dilapidated furniture, packing boxes, decorative boards, etc.
• This part of waste contains organic pollutants, such as painted doors and windows, organic resin-coated boards, etc. 
• Category C is wood that has undergone anti-corrosion treatment and contains heavy metals (arsenic, chromium, copper, lead), such as railway sleepers, old electric pole stakes, and dismantled park paving slabs.

In fact, for European countries such as Germany, Poland, and the Netherlands, there are some challenges in using wood waste to process wood pellets. The following RICHI will give you a brief explanation:

Woody waste is characterized by large volume and light weight. The bulk density of pine wood is only 0.45 t/m3; all kinds of waste wood have different shapes, and it is difficult to stack them neatly, which makes the transportation cost of waste higher than other materials such as coal.

In addition, the wood chips stacked in the open air have high moisture content and increased viscosity, so the wood chips are easy to stick together, making pipeline transportation difficult.

Large vehicles or barges are used to transport wood waste in Europe, and some also use trains. Special unloading machinery is required for storage and transportation sites or docks. From the perspective of fire prevention, the storage site requires a large area.
 

Wooden waste transport methods in the wood pellet plant include belt conveyors, screw conveyors, closed pneumatic pipelines, etc. Each mode of transportation has certain restrictions, such as airtight pneumatic pipelines that cannot transport larger pieces of wood, screw conveyors that cannot transport long distances, and belt conveyors that emit dust.

Screws, nails and other metal objects are attached to the old waste wood, glass is attached to old doors and windows, and wallpaper is stuck to waste fiberboard, which makes it difficult for the machine to achieve efficient disposal. The proportion of various sundries in waste wood is 3%~5%.

Compared with freshly felled logs, the waste wood waste has a low moisture content, dust will adhere to the surface, and a large amount of dust will be generated during crushing and grinding. Therefore, the removal of impurities is a topic of great concern to us, so when we customize the wood biomass pellet production line for customers, we must be very clear about the raw materials of customers.

For example, in this wood pellet machine Germany project, the customer only said that the raw material was dry spruce sawdust in the initial consultation, but the customer's raw materials also include other wood wastes, and the moisture content will also be high.

Different raw materials will match different wood pellet production processes and wood pellet equipment configurations. It is recommended that all customers fully consider the situation of raw materials, including the difference between the use of raw materials in the early and late stages.

• 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. 
• The quality of lignin fiber of Class A wood waste is equivalent to that of logs, which can completely replace logs to produce wood-based panels.
• There are a lot of waste boards in Class B waste, with many sundries, the lignin fiber in the waste boards is short, and the quality is not as good as logs, and the raw materials for processing into sandwich boards need to increase the amount of adhesives and increase the cost.
  
  In addition, the old boards contain chemical resins. During the drying process of the recycled boards, the residual resins in the wood chips will volatilize, which will affect the quality of the products. Therefore, Class B wastes are suitable for processing into wood fuels.
• There are heavy metal residues in Class C waste, so wood pellet processors require wood chip suppliers not to use Class C waste as raw materials.

Even in the face of many challenges, we have still solved practical problems for many European customers, and established dozens of pellet production lines in Europe. Recent transactions include: 5T/H Wood Pellet Factory In Austria, 2T/H Wood Pellet Production Line In Netherlands, Germany 2-2.5 Tons/hour Computer Control Wood Pellet Plant, 2T/H Wood Pellet Production Line In Poland, Romania 2-2.5TPH Sawdust Pellet Plant Project, Iceland 1-1.5 T/H Wood Pellet Line, etc.

Wood waste is an important renewable resource and energy source. Currently, there is a huge market demand for wood pellets and their production equipment. As the global economy recovers, it is hoped that more wood pellet business investors seize the opportunity to develop wood fuel pellet products and contribute to global carbon emission reduction.
