What granulator use wet granulation to make pellets

Wet granulation is a widely used technique in the pharmaceutical, food processing, and chemical industries to create granules or pellets from fine powders. This process involves the mixing of a liquid binder with dry powders to form granules that are more easily handled, transported, and ultimately, processed. One of the key pieces of equipment employed in wet granulation process method is the granulator. In this article, we will delve into the fascinating world of granulators and explore how they use wet granulation to create pellets.

Understanding Granulation

Granulation is the process of transforming fine powder particles into larger, free-flowing, and more uniform granules. This is particularly important in industries where the handling and flow properties of materials are critical. Granules are easier to compress into tablets, fill into capsules, or mix with other ingredients. Additionally, granulation can improve the stability and content uniformity of pharmaceutical formulations.

The Role of Granulators

Granulators are essential machines in the wet granulation process. They play a pivotal role in mixing the powders and binder, as well as in shaping the resulting wet mass into granules. There are several types of granulators, each with its own set of advantages and limitations. However, all granulators used for wet granulation share some common principles.

Wet Granulation Process

Wet granulation typically follows a series of well-defined steps:

  1. Mixing: The first step involves blending the dry powders with a liquid binder. The binder can be water, ethanol, or other solvents, depending on the specific requirements of the process and the materials being used. This mixture forms a damp mass.
  2. Agitation: The damp mass is transferred to the granulator, which initiates the wetting and mixing process. The granulator uses various mechanical means, such as impellers, blades, or choppers, to promote even distribution of the binder throughout the powder.
  3. Nucleation: As the granulator continues to mix, small granules or nuclei begin to form. These nuclei serve as the foundation for the larger granules to develop.
  4. Growth: The nuclei grow in size as the granulator continues to agitate the mixture. The liquid binder acts as an adhesive, binding the powder particles together, forming granules.

Types of Granulators

There are several types of granulators used in wet granulation, including:

  1. Pan Granulators Equipment: It uses a disc and a scraper to rub against each other to produce particles. The equipment is also equipped with a water spray device. They are suitable for small production.
  2. Drum Granulators: These granulators work by tumbling the damp mass in a rotating drum pelletizer. The gentle tumbling action encourages the growth of granules.

Benefits of Wet Granulation

Wet granulation offers several advantages over dry granulation or direct compression methods. Some of the benefits include:

  1. Improved Flow Properties: Granules have better flow properties than powders, making them easier to handle and process.
  2. Enhanced Content Uniformity: The uniform distribution of the binder ensures consistent drug content in pharmaceutical formulations.
  3. Better Compression Characteristics: Granules compress more uniformly and at lower pressures, making them ideal for tablet production.
  4. Increased Stability: Granules can protect sensitive ingredients from degradation during storage.

Conclusion

Granulators play a crucial role in the wet granulation process, transforming fine powders into uniform, free-flowing granules. Depending on the specific requirements of the industry and application, various types of granulators are employed to achieve the desired granule properties. Wet granulation offers several advantages, including improved flow properties, content uniformity, and stability. Understanding the intricacies of granulators and wet granulation is fundamental for industries that rely on high-quality granulated products.

Why a Pan Granulator is a Good Choice for Making Organic Fertilizer

Fertilizer can come in a range of different forms, from powders to sticky solids, and granules. One of the best things about granulated fertilizer is that it is very easy to handle, store and transport.

Our high quality pan granulators are a good choice for making organic granulated fertilizer because they are simple to use and quite cost-effective, allowing for the production of large quantities of fertilizer with minimal intervention. Machines are listed in terms of their annual output capacity, and pan granulators offer a good balance between large outputs and reasonable prices.

Flexible and Reliable

Powdery fertilizer disc granulators are a good choice for making organic fertilizer because they produce a high yield of easy to manipulate granules, and can handle a range of different organic materials. Some machines, such as the spherical granulators, can work with poultry manure without having to dry the output first. Others will need organic matter to be fermented before they can work with them.

Granules may be ball-shaped or cylindrical depending on the type of machine. Both types of granule are relatively easy to handle and transport, making pan granulators handy for those who need to work with large amounts of fertilizer.

Effective Quality Control

When you are dealing with crop fertilizer you want to make sure that the product you make is suitable for the crop that it will b used with. Quality control is essential. The raw materials and the end product should both be tested to ensure the pH, density and melting point are as expected. Visual tests can give a good indication of the state of the fertilizer, especially if it is an experienced person examining them.

There are strict requirements on the nitrogen and phosphate content that is allowed in commercial fertilizers, for safety reasons. It is also important to make sure that any byproducts are safe too. Remember that only a small amount of the nitrogen that is contained in an average fertilizer will be taken up by the plants. the rest will run off into the groundwater, and can then contaminate drinking water. For this reason, the makeup of fertilizer should be strictly controlled.

Pan granulators give a lot of control to the maker of the fertilizer, allowing you to precisely make up the solution that will be added to the pan, controlling the concentration to exact levels. You can test the solution before spraying it onto the solids, and you can regulate the temperature, to reach the desired consistency when the fertilizer end product comes out.

Granular fertilizers made by pan pelletizer are so much easier and cheaper to handle than manures. There are still benefits to using manure if it is readily available near the farm. However, for those who are not able to source manure for fertilizer on a large enough scale, granulated fertilizer is efficient and affordable. There are some who are experimenting with treating sewage to remove harmful heavy metals since sewage also contains the nutrients that would make good fertilizer, but until the technology exists to do that reliably and safely, pan granulators offer a practical solution.

Some tips for you to know more about pan granulator

A Pan Granulator or Pelletiser is a disk-shaped machine mounted on a pedestal that is used to turn fertilizer into granules. It differs from other machines used for granulation because of it has been developed to produce much higher pelleting ratios.

It can be used in combination with other fertilizer making machines such as crushers, mixers, and dryers to create a really efficient fertilizer production line with a capacity scale that is adjustable to suit individual needs.

What can a Pan Granulator do for you?

A Pan Granulator has many functions. It can granulate both organic and compound fertilizer pellets and is also capable of pelletizing many different types of granular particles, something that is usually beyond the scope of other granular fertilizer making machines. Such as, drum type fertilizer granulator, fertilizer roller compactor and new designed organic fertilizer granules making machine. Pan Granulators can also deal with raw materials in all kinds of conditions including wet and dry conditions. However, for best results, it is recommended to keep the moisture ratio of the materials to around 20% to 30%. If you are looking for a cost-efficient fertilizer pelletizer that can improve work efficiency and reduce labor intensity, a pan granulator is definitely the right choice for you.

In addition to granulating fertilizer, it can be used for a wide variety of other granulating requirements such as chemical pellets, medicinal tablets, animal feed, metal granules, coal briquettes, etc. It mainly uses wet granulation technology for pelletizing.
Since the materials needed for processing are easily obtainable a pan granulator will provide good economic yields at a relatively low investment. A major benefit of using a pan granulator is that it does not produce any harmful residues during the production process which makes it extremely eco-friendly.

How to Control the Size of Fertilizer Pellets?

Once the materials are placed in the granulator pan, it is rotated by a rotor with teeth attached. The teeth will shred the materials, mixing, agglomerating, and condensing them, until eventually the material will become granulated into round pellets. The size of the pellets can be controlled by controlling the moisture ratio and speed of the rotation. If the moisture content is high and the speed of rotation low, the particles will be formed into larger pellets. To get smaller granules the process needs to be reversed with lower moisture content and higher rotation speed.
