Sawdust Briquetting Machine Application

The main function of sawdust briquetting machine is to mold biomass raw materials such as sawdust, wood chips and other biomass materials into cylindrical or rectangular fuel blocks through high-pressure extrusion, and these fuel blocks can be used as an environmentally friendly energy source to replace the traditional fossil fuels in scenarios such as industrial boilers, biomass power plants, and home heating stoves. This equipment not only improves resource utilization, but also reduces pollution to the environment.

Charcoal briquetting machine working principle

• Operation steps of charcoal briquette machine：

Raw material preparation: biomass raw materials such as sawdust and other biomass raw materials are pre-treated by crushing, dust removal and iron removal to ensure that the raw materials are dry and free of impurities.
Feeding and compression: Feed the raw materials into the pelletizing bin through bucket elevator, and enter the pelletizing chamber of the briquetting machine through quantitative conveyor and tempering device, and compress the raw materials into high-density fuel briquettes through the friction force of the pressure rollers and molds.
Cooling and Finished Product Processing: The temperature of the pellets after briquetting is high, they need to be cooled down to room temperature by the counter-current cooler, and then the dust is filtered through the vibrating screen to finally get the finished fuel.

What raw materials can be used to make charcoal

The raw materials for making charcoal come from a wide range of sources, mainly including natural wood and agricultural and forestry waste. These raw materials need to meet the conditions of high carbon content, moderate volatile substances, and easy pyrolysis

• Hardwood: oak, birch, oak, jujube, fruit wood (such as apple wood, pear wood), camphor wood, etc.
• Soft wood: pine, poplar, cedar, bamboo, etc.
• Agricultural and forestry waste: sawdust, sawdust (leftover materials from furniture factories and wood processing plants)
• Branches, bark, and roots (residues from forestry pruning or logging)
• Bamboo shavings, bamboo knots (bamboo processing waste)
• Agricultural waste: straw (corn straw, wheat straw, rice straw, etc.)
• Fruit shells (coconut shells, walnut shells, apricot shells, peach shells)
• Rice husks (rice husks, rice bran, peanut shells, cottonseed shells)
• Biomass materials: mushroom sticks (waste substrates from edible mushroom cultivation, including sawdust, cottonseed hulls, etc.)
• Animal manure (such as cow manure, horse manure, mixed with sawdust to increase carbon content)
• Pulp waste (such as waste paper and cardboard, requiring de ink treatment)

How to make charcoal

• The core principle of making charcoal is to release volatile substances (such as water, tar, and gas) from biomass such as wood through pyrolysis reactions in a high-temperature and oxygen deficient environment, leaving behind solid products mainly composed of carbon elements.
• Raw material pretreatment
• Crushing: Crush raw materials such as sawdust, straw, and fruit shells into particles of less than 10mm.
• Drying: Reduce the moisture content of the raw materials to 8% -12% through a dryer to avoid moisture affecting the carbonization quality.
• Rod making and molding
• Equipment: Use a rod making machine (spiral extrusion or hydraulic)
• Principle: Under high temperature and high pressure (about 300 ℃, 15-20MPa), the raw materials are extruded into rod-shaped solid fuels (without the need for adhesive)
• Advantages: High density and long combustion time of formed charcoal, with a raw material utilization rate of over 90%
• Carbonization treatment
• Equipment: Carbonization furnace (divided into earth kiln, dry distillation, continuous type, etc.)
• technological process:
• Low temperature moisture removal: Place the formed rod into a carbonization furnace, slowly raise the temperature to 100-150 ℃, and remove residual moisture.
• High temperature calcination: Raise the temperature to 400-600 ℃ to decompose volatile substances in the wood into gases (which can be recycled as fuel)
• Cooling down: After carbonization is completed, turn off the heating source and wait for the temperature inside the furnace to drop below 100 ℃ before turning on the furnace to collect charcoal.

Scope of use of rice husk charcoal machine

Sawdust briquetting machine is suitable for processing all kinds of biomass waste, such as wood chips, rice husk, straw, peanut shells, fruit shells, etc. It is widely used in agriculture, forestry, energy and other fields. Its finished fuel can be used as industrial boiler fuel, biomass power generation fuel or home heating fuel.

Type of materials that can be handled

Suitable for a wide range of environments

Application scenarios of charcoal machine

• Barbecue fuel: Mechanized charcoal has become the preferred choice in the catering industry due to its stable combustion, smoke-free and odorless properties.
• Industrial raw materials: used for the production of chemical products such as activated carbon, silicon carbide, and ferrosilicon alloy.
• Agricultural use: Charcoal powder can improve soil structure and enhance water and fertilizer retention capacity.
• In the field of environmental protection: as a biomass fuel to replace coal and reduce carbon dioxide emissions.

sawdust briquette：Buying Advice

When choosing a sawdust briquetting machine, factors such as the production capacity of the equipment, the type of applicable raw materials, the complexity of operation and after-sales service should be considered according to the actual needs. For example, a small wood processing plant may choose a small multifunctional model, while a large industrial user may need a higher capacity machine.
