Biomass briquetting machine is a kind of equipment that presses biomass raw materials such as crop straw, sawdust into lump fuel, which is widely used in the field of energy and environmental protection. However, different raw materials have different characteristics in the processing, so when using biomass briquetting machine, corresponding measures should be taken according to the characteristics of raw materials to ensure the stable operation of the equipment and obtain ideal briquetting effect. (Advantages and disadvantages of biomass briquettes)The following are some matters needing attention when processing different raw materials:

1. Water content control of raw materials

The moisture content of raw materials is an important factor affecting the quality of briquetting. Generally speaking, biomass briquetting machines have certain requirements on the moisture content of raw materials, usually between 10% and 15%. If the moisture content is too high, it will easily lead to loose briquetting or equipment blockage; If the moisture content is too low, it may cause cracking of briquette or equipment wear. Therefore, raw materials should be dried or humidified before processing to achieve appropriate moisture content.

2. Particle size of raw materials

The particle size of different raw materials will also affect the briquetting effect. Fine particles such as sawdust can be used directly, while large-volume raw materials such as straw need to be crushed to ensure uniform particles. Generally, the particle size should be controlled below 5mm in order to better enter the mold for pressing.

3. Difference of raw material composition

The composition difference of different raw materials will affect the forming effect of briquetting. For example, straw fiber is longer and has higher toughness, which is more difficult to press than sawdust, so it is necessary to adjust the pressure and temperature parameters of the equipment. Wood chips contain certain resin components, which are easy to soften at high temperature, which is helpful for molding, but it may also lead to mold blockage and need to be cleaned in time.

4. Equipment parameter adjustment

According to the characteristics of raw materials, the parameters of biomass briquetting machine such as temperature, pressure and mold speed should be adjusted reasonably. For example, when processing hardwood raw materials, it is necessary to increase the pressure and temperature; When processing soft fiber raw materials, the pressure can be appropriately reduced. In addition, it is necessary to regularly check the wear and tear of the equipment to ensure its normal operation.

5. Impurity cleaning

If the raw materials are mixed with hard impurities such as stones and metals, it will not only affect the quality of briquetting, but also damage the equipment. Therefore, raw materials should be cleaned before processing, and impurities should be removed by screen or magnetic separation device.

When the biomass briquetting machine processes different raw materials, it needs to be adjusted and treated according to the characteristics of the raw materials. By reasonably controlling moisture content, particle size and equipment parameters, and paying attention to impurity cleaning, the quality and production efficiency of briquetting can be effectively improved and the service life of equipment can be prolonged. In practice, users should flexibly adjust various processes according to their own production needs to achieve the best results.
