Briquetting Process Guide: Applications, Process and Waste Solution

Briquetting systems are machines that compress loose material. They include sawdust, paper, wood chips, agricultural waste, and other biomass. These machines turn the material into compact briquettes.

Installing a briquetting system can improve efficiency, sustainability, and profits for many manufacturing businesses. Here’s an in-depth look at what briquetting is and the benefits it offers. Learn how a briquetting system can transform your manufacturing process.

Briquetting is the process of compressing loose material into compact, solid briquettes. It also involves molding the material.

Briquettes are typically cylindrical logs or blocks. They can substitute for metals, coal, and other non-renewable fuels in manufacturing applications. They require heat and energy generation.

The briquetting process uses high pressure and temperature to compact the material. This binds it together without the need for any more binders or adhesives. The natural lignin in biomass acts like glue. As they compress under heat, they hold the briquettes together.

Briquettes are extremely dense and energy-concentrated compared to the loose bulk material. This makes them easier to handle, store, and transport. Briquettes also burn more efficiently and uniformly compared to loose biomass. This makes them ideal for use as fuel in boilers, furnaces, stoves, and other heating applications.

Installing a briquetting system is a major investment that needs careful planning. However, it can yield tremendous benefits for manufacturers with enough waste material streams.

Compress low-value sawdust, paper scraps, wood chips, and metal debris into compact, energy-dense briquettes. This reduces waste disposal costs. It lowers fossil fuel consumption and creates a profitable new product line.

Briquetting systems automate fuel production. They improve combustion efficiency and decrease storage and transportation costs. This promotes sustainability and improves workplace safety by reducing dust. The upfront costs are significant.

But, a briquetting system matched to your waste materials can lead to a short payback period. A sized and designed system is key. This is due to energy savings and revenue from selling briquettes.

Your manufacturing plant may generate volumes of biomass or metal waste. Integrating a briquetting system can be a smart investment. It can transform your production processes for the better.

Best Guide on Charcoal Briquette Production Process

Charcoal briquettes not only provide long-lasting heat compared to traditional non-renewable fossil fuels, but they also burn without smoke or odor. In addition, comparing to old-fashioned charcoal, investing in a charcoal briquetting factory is a low-investment, high-return project !


Investing a Charcoal Briquettes  Processing Line with a Reasonable Price

With so many advantages, it is no wonder that the charcoal briquette is chosen by many countries’ customers, including India, Uganda, Kenya, and others, and widely used in domestic and industrial fields in recent years. So, what are the raw materials used to make the charcoal briquette? How is the charcoal briquette produced? What is the use of the charcoal briquette produced? This article will answer these questions one by one in detail.

How to produce high quality charcoal briquettes is one of the main concerns of many investors who are new to the charcoal briquette processing industry. Starting a charcoal briquetting plant is not an easy task. Before you begin, you have to understand the best charcoal briquettes production steps and then do a series of preparations (such as developing a business plan, choosing a site, investing capital, and purchasing supporting processing equipment. ) Generally speaking, the whole production process can be divided into five sections. 

Step 1. Raw material collection 

What are the main raw materials for manufacturing charcoal briquettes? Charcoal briquette is a dark or brown solid porous fuel made from sawdust, crop straw, peanut shells or other biomass waste through a series of working processes. Depending on the raw material, charcoal can be divided into three types: hardwood charcoal, softwood charcoal and mechanical charcoal. Hardwood charcoal can be produced from beech and oak; softwood charcoal can be produced from elm, basswood and willow; and mechanical charcoal can be produced from sawdust and other materials.

Step 2. Crushing Process

After a certain amount of raw material is prepared, it is crushed in a crusher or a hammer mill, usually into 5mm or smaller pieces to produce high-quality charcoal briquettes. However, if the raw material is already in powder forms, such as sawdust or bamboo powder, then this step should be omitted.  

Step 3. Drying Process

The crushed raw material will be sent to the dryer to reduce the moisture in the raw material. 

If the raw material is fed directly into the briquetting machine without drying, the volume of raw material with high moisture content will suddenly expand at a sharp increase in temperature, which may lead to an explosion. And the excessive moisture will increase the energy loss in the briquetting process, not only that, but it will also make the charcoal produced prone to bending and breaking after carbonization, which directly has a bad effect on the quality of the finished product. After drying, the water content of the raw material is reduced to about 10% for a uniform burning point.

Step 4. Briquetting Process

Briquetting is the core step of the whole making process. Upon entering the charcoal-making briquette machine, the raw material will be subjected to three types of forces: the frictional force, the centripetal force from the walls, and the main driving force from the briquetting machine. Under these three forces, the prepared raw material will be pressed into a bar shape. As the charcoal briquettes are discharged from the bottom of the machine, they can retain their shape due to the moisture, the binder, the temperature (about 105℉ or 40℃), and the pressure of the briquette machine. It should be noted that the charcoal briquettes obtained in this step are not completely carbonized, but only the surface is highly carbonized, so they are semi-finished charcoal biomass briquettes.

Step 5. Carbonation Processing

Carbonization is an important part of the charcoal briquette-making process. The carbonization process is the core of the technology for making charcoal briquettes. With the development of society and the awakening of environmental awareness, the charring step is usually carried out in a charcoal furnace. The charcoal kiln used before is time-consuming and polluting to the environment, so more users choose to use charcoal carbonization furnaces in recent years.

The Application of The Charcoal Briquetting Products 

  • The application spectrum for charcoal briquettes is wide. Charcoal briquettes are more than three times denser than charcoal, and they do not produce a lot of smoke when burned, so they can take carbon’s place for barbecue.

  • In industry, charcoal briquettes are used in the production of carbon disulfide and in steel smelting. 

  • Charcoal briquettes are also used as supplementary fuel for boilers because their density is close to that of coal, with a calorific value of 5,500-7,000 calories per kilogram, but their ash content is obviously lower than that of coal.
