As an efficient biomass energy processing equipment, wood briquetting machine is widely used in agriculture, forestry and biomass energy production. It can process all kinds of wood wastes, crop straws and other raw materials into high-density briquette fuel, which not only improves the utilization rate of resources, but also reduces environmental pollution. However, the selection of raw materials is very important for the production efficiency and product quality of wood briquetting machine. When using wood briquetting machine, it is necessary to follow certain principles of raw material selection to ensure the normal operation of the equipment and the quality of finished products. The following are some main principles for selecting raw materials.

1. The moisture content of raw materials is moderate.

The moisture content of raw materials is one of the important factors affecting the production efficiency and finished product quality of wood briquetting machine. Generally speaking, wood briquetting machines have certain requirements on the moisture content of raw materials, usually between 8% and 15%. If the moisture content of raw materials is too high, it will lead to difficulty in forming and even blockage in the process of briquetting; However, if the moisture content is too low, it may lead to insufficient strength of the briquette and easy to break. Therefore, when selecting raw materials, attention should be paid to controlling its moisture content within a suitable range.

2. The raw material particles are uniform.

The size of raw material particles directly affects the forming effect of wood briquetting machine. Too large particles may lead to poor operation of the equipment, while too fine particles may affect the density of compact. Therefore, it is suggested that raw materials should be crushed before use to make their particle size uniform, usually controlled between 3-5 mm. This can ensure the uniform stress of raw materials in the compression process, thus improving the quality and density of finished products.

3. Wide sources of raw materials and low cost.

In order to reduce the production cost, it is an important principle to choose raw materials with wide sources and low prices. Common raw materials of wood briquetting machine include sawdust, sawdust, bark, crop straw (such as rice straw and wheat straw), corncob and other biomass wastes. Most of these raw materials are wastes from industrial or agricultural production. They are rich in sources and low in cost, which can not only save resources, but also have good economic benefits.

4. Raw materials are clean and free of impurities.

If the raw materials contain too many impurities (such as stones, metals, glass, etc.), it will not only affect the quality of finished products, but also cause serious damage to the wood briquetting machine. Therefore, when selecting raw materials, we should try to select materials with high cleanliness, and screen or remove impurities before putting them into the equipment to avoid abrasion or blockage of the equipment caused by impurities.

5. Raw materials have high calorific value and can be regenerated.

The fuel produced by wood briquetting machine is mainly used to replace traditional fossil energy such as coal, so the selected raw materials should have high calorific value to ensure that the finished products can release enough energy when burning. In addition, renewable resources are given priority as raw materials, such as agricultural and forestry wastes and biomass wastes. This not only meets the requirements of environmental protection, but also effectively reduces the dependence on non-renewable energy.

6. Raw materials are easy to store and transport.

In actual production, the storage and transportation costs of raw materials are also important factors to be considered. Choosing raw materials that are easy to store and not perishable can reduce the loss during storage. At the same time, try to choose localized raw material sources to reduce transportation costs and improve production efficiency.

7. Combining the characteristics of local resources

There are differences in natural resources and agricultural production in different regions, so the selection of raw materials for wood briquetting machine should be combined with the characteristics of local resources. For example, in areas rich in forestry resources, sawdust and sawdust can be given priority as the main raw materials; In agricultural planting areas, crop straw and rice husk can be used as raw materials. This way of choosing according to local conditions can not only reduce the procurement cost, but also better realize the recycling of resources.

The selection of raw materials for wood briquetting machine is directly related to the operation efficiency of equipment, the quality of finished products and economic benefits. In actual operation, the renewable biomass materials with moderate moisture content, uniform particles, cleanliness and high calorific value should be reasonably selected according to equipment requirements and local resources. At the same time, we should also pay attention to reducing the storage and transportation costs in order to achieve a win-win situation of economic benefits and environmental protection benefits. Selecting raw materials scientifically and reasonably can not only improve the use value of wood briquetting machine, but also contribute to sustainable development.
