Carbon black, is a black powder or particle mainly composed of carbon atoms. Due to its unique physical and chemical properties, it plays an important role in multiple industry sectors. Specifically, it is widely used in rubber, plastics, inks, coatings, electronic components, leather chemicals, dry batteries and many other industries. Carbon black is a type of fine carbon particles, which is made by burning or pyrolyzing carbonaceous materials in the absence of oxygen. Actually, it has the charcteristics of good conductivity, pigmentation and reinforcing properties. What’s more, carbon black can not only improves the mechanical strength and service life of products, but also provides better color and gloss.

Pan granulating machine for sale

Pan granulator is the key equipment for wet granulation method, which uses centrifugal force to granulate pellets. It not only has the simple structure and flexible operation, but also has a high granulation rate of more than 93%. For this reason, it is an ideal machine for many mineral fertilizer manufacturers because of its high efficiency.

Rotary drum granulating machine for sale

Rotary drum fertilizer granulator is a commonly used equipment in compound fertilizer production, which is suitable for larger scale plant. It adopts wet granulation method, through a certain amount of water or steam to adjust the humidity in the cylinder, causing sufficient chemical reaction of raw materials. Simultaneously, with the help of the rotation of the cylinder, the carbon black particles are extruded and formed into balls.

Double roller extrusion granulator for sale

Double roller extrusion granulator adopts dry granulation method in the process. Therefore, it is suitable for materials with moisture content less than 10%. This equipment is usually used for small-scale production. In addition, It has the advantages of good granulation effect, high particle strength and low energy consumption, thus making it an ideal choice for many manufacturers.

What is carbon black granulation production line

The carbon black granulation production line is a set of equipment that converts carbon black powders into pellets. Generally speaking, the complete production process mainly includes raw material preparation, crushing, mixing, pelletizing, drying and cooling. Among which, the most important process is pelletizing process. These processes not only require precise control of various parameters to ensure product quality, but also take into account economic factors such as production efficiency and energy consumption.

In the production of carbon black, the granulation is the key process in the entire granulation production line. In brief, the application of carbon black granulation technology not only solves environmental and health and safety issues, but also improves material utilization and reduces transportation costs. For these reasons, a complete equipment of the carbon black granulation line is very important.

2 carbon black granulation production methods

Carbon black, as a widely used synthetic material, it has important industrial value and diverse uses. In the production process of carbon black, the two main granulation methods are dry method and wet method. Particularly, the dry granulation method is known for its high efficiency and low cost, while the wet granulation method has been favored because of its more flexible and environmentally friendly characteristics. Following are the detailed introduction of 2 granulation methods:

Carbon black dry granulation method

Granulation principle

Carbon black dry granulation method is a commonly used method. It is the process of converting carbon black powders into granules under dry conditions. Generally, this process does not need to add water or other binders, thus calling it as dry granulation method.

Granulation characteristics

  1. High efficiency: The carbon black dry granulation method can quickly turn the powder materials into pellets. Because the reaction time is very short, then has the advantages of simple operation and high production efficiency. Therefore, it is more suitable for large scale production.
  2. Low cost: By using this type of granulatuion method, there is no need for additives and other adhesives. Therefore, the production cost is relatively low, so it is suitable for plants with low cost budgets.
  3. High purity: Since there is no need to add water or other solvents, the carbon black finished pellets always have high purity and stable quality.

Application fields

Carbon black dry granulation method is widely used in rubber products, plastic products, printing inks and other fields. Due to its high pellets purity and controllability, making the carbon black have good application prospects in these fields.

Carbon black wet granulation method

Granulation principle

Carbon black wet granulation method is through adding appropriate amount of water or other liquid binder to turn the carbon black powders to form ball-shaped particles. Different from dry granulation methods, the finished pellets after wet pelletizing have a high water content, so it will need a dryer to dry out the moisture, and then use a cooler to cool down the temperature. Finally, you can get uniform carbon black granules.

Granulation characteristics

  1. Controllable particle size: Using the wet granulation method, the size and shape of finished particles can be controlled, and you can easily get regular shape and uniform particle size.
  2. Wide adaptability: Wet pelletizing method can adjust the type and dosage of binder to adapt to different properties of carbon black and different application requirements.
  3. Eco-friendly: Through the wet granulation treatment, the flying of carbon black dust can be  reduced. Considering from the perspective of overall environmental protection, the wet method can better control and dispose the waste water and exhaust gas when processing.

Application fields

Wet granulation method of carbon black is widely used in coating, ink, cosmetic and other industries. The adjustable pellets of wet carbon black enables it to realize more application potential in these industries.

What is the process of carbon black production line?

The establishment of a carbon black production line involves many process, a complete carbon black pelletizing line usually includes raw material preparation, crushing, mixing, pelletizing, drying and cooling, sieving, packaging and so on. The following is the detailed granulation process.

Carbon black powder raw materials need to be granulated before a series of treatment processes. First of all, through the drying and sieving processes to remove impurities and moisture to ensure the purity of the raw material and the appropriate particle size. This step usually requires dryer drying, as well as sieving machine to remove unqualified particles.

Mix carbon black powder with binder or other additives in proportion to the mixer for full mixing, so that the powder particles are uniformly attached to the surface of the binder, to facilitate the subsequent granulation.

This step is the key process in the pelletizing production line, which is to make the raw material powder into pellets through the pelletizing machine. Granulation can effectively improve the efficiency of material use and product quality. For this process, we have 3 kinds of equipments for you to choose, i.e. rotary drum pelletizer, disc pelletizer and double-roller extrusion pelletizer, and then you will use the pelletizer to make qualified carbon black pellets.

For wet pelletizing process, the carbon black granules after pelletizing contain too much water. Therefore, you need to remove the surface and internal moisture with dryer first, drying and cooling to get stable granule quality finally. Dry granulation does not require drying and cooling steps.

The dried granules are graded by sieving equipment to remove unqualified granules and too fine granules. The unqualified particles can be recycled and re-pelletized, so that it finally reaches the composite required particle size.

The carbon black particles that meet the quality requirements are packaged for easy storage and transportation.
