Activated carbon is a highly porous material that is used in various industries for its adsorption and purification properties. It is produced by heating carbon-rich materials, such as coconut shells, wood, and coal, at high temperatures in the absence of oxygen to create a highly porous material with a large surface area.

One such raw material for activated carbon production is groundnut shells. Groundnut shells are the outer coverings of peanuts, and they are a cheap and abundant waste material that can be used as a sustainable and eco-friendly source of activated carbon.

Activated carbon from groundnut shells has numerous applications, such as water treatment, food processing, and air purification. It is highly effective in removing impurities and pollutants, making it an essential component of many industrial processes.

Sustainable and eco-friendly production practices are crucial in the production of activated carbon. By using renewable and abundant raw materials like groundnut shells, companies can reduce their environmental impact and promote sustainability. This approach also creates a cost-effective alternative to traditional raw materials, reducing production costs and increasing efficiency.

The process and equipment are two main sections used in groundnut shell activated carbon solution, as an activated carbon making machines manufacturer, it’s necessary to provide suitable solutions for activated carbon making, here is analytics for equipment used in activated carbon production.

Groundnut shell activated carbon equipment

There are several types of equipment used in the production of activated carbon from groundnut shells, each with its own advantages and disadvantages. The choice of equipment will depend on the activation method used and the specific requirements of the production process. This section will discuss the most commonly used equipment and their suitability for different activation methods.

Rotary Kilns

Rotary kilns are the most commonly used equipment for activated carbon production and are suitable for both physical and chemical activation methods. They consist of a rotating cylinder lined with refractory material and are heated using gas, oil, or electricity. Rotary kilns are effective for producing high-quality activated carbon and can handle large volumes of raw material. They are also relatively easy to maintain, making them a popular choice for many manufacturers.

activated carbon adsorption box

The activated carbon adsorption box for waste gas treatment is suitable for purifying organic waste gas generated by various industries. The organic solvents that can be treated include benzene, ketones, fats, alcohols, aldehydes, ethers, alkanes, and their mixtures. The adsorption of organic waste gas by activated carbon with many micropores is one of the most effective industrial treatment methods. Adsorption can achieve a purification efficiency of up to 90-95% for organic waste gas, and the activated carbon adsorption bed is easy to replace when it becomes saturated.

cyclone filter

A bag filter is a dry filtration device. It is suitable for capturing small, dry, non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt, which uses the filtering effect of the fiber fabric to filter the dust-containing gas. When the dust-containing gas enters the bag filter, the large and heavy dust particles settle down due to the effect of gravity and fall into the ash hopper. The gas containing finer dust particles is filtered out as it passes through the filter material, allowing the gas to be purified.

Other Specialized Equipment

In addition to rotary kilns, reactors, and carbonizers, other specialized equipment may be required for specific activation methods or production processes. This may include air pollution control systems to capture and treat any emissions generated during the production process, as well as grinding and sieving equipment to prepare the groundnut shells for activation.

Design considerations for production equipment: size, capacity, and efficiency

When designing production equipment for activated carbon production from groundnut shells, several factors need to be taken into account to ensure optimal performance and efficiency. This section will discuss some of the most important design considerations for production equipment, including size, capacity, and efficiency.


The size of the production equipment should be determined based on the volume of raw material that will be processed and the desired output. Too small equipment may result in inefficient production and increased downtime, while oversized equipment can lead to excessive energy consumption and unnecessary costs.


Capacity refers to the amount of activated carbon that can be produced by the equipment in a given period. The production capacity should be chosen based on the anticipated demand for the product and the available resources, including raw materials and labor. A balance must be struck between maximizing production capacity and ensuring consistent product quality.


Efficiency is a crucial factor in the design of production equipment, as it directly impacts the cost of production. The equipment should be designed to maximize efficiency by minimizing energy consumption, reducing waste, and optimizing the use of resources. This can be achieved through the use of advanced control systems, process automation, and regular maintenance.

Other Design Considerations

Other important design considerations for production equipment include safety, reliability, and ease of maintenance. The equipment should be designed with safety features to prevent accidents, such as explosion-proof motors and emergency shutdown systems. Reliability is also critical to ensure consistent product quality and minimize downtime. Finally, equipment should be designed with ease of maintenance in mind, including easy access to components for cleaning and repair.
