I&#8217;m a supplier of granulation machines, and I often get asked about the methods to produce spherical granules using these machines. In this blog, I&#8217;ll share with you some of the common techniques and how our granulation machines can help you achieve those perfect spherical granules. <a href=\"https:\/\/www.hnmwmequip.com\/granulation-machines\/\">Granulation Machines<\/a><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.hnmwmequip.com\/uploads\/47002\/small\/adjustable-angle-disc-granulator18bcb.jpg\"><\/p>\n<h3>1. Agglomeration Agglomeration is one of the most popular methods for producing spherical granules. It involves sticking together smaller particles to form larger, spherical masses. Here&#8217;s how it works:<\/h3>\n<p><strong>Simple Agglomeration Process<\/strong>:<br \/>\nFirst, you start with your raw materials in a fine &#8211; particulate form. These could be powders of various chemicals, food ingredients, or pharmaceuticals. Then, you introduce a binding agent. This could be a liquid polymer, a sugar syrup, or even water in some cases.<\/p>\n<p>When the binding agent is sprayed onto the particles in a rotating drum or a fluidized bed (features of our advanced granulation machines), the particles start to clump together. The rotation or the fluidizing action helps the clumps to roll around and gradually form spherical shapes.<\/p>\n<p><strong>Benefits of Agglomeration<\/strong>:<\/p>\n<ul>\n<li>It can improve the flowability of the granules. Spherical granules tend to flow more easily compared to irregularly &#8211; shaped ones, which is great for handling and packaging processes.<\/li>\n<li>You can control the size of the granules by adjusting the amount of binding agent and the processing time. With our granulation machines, you have precise controls to get the exact granule size you need.<\/li>\n<\/ul>\n<h3>2. Extrusion &#8211; Spheronization This is a two &#8211; step process that is widely used in the pharmaceutical and chemical industries.<\/h3>\n<p><strong>Extrusion Step<\/strong>:<br \/>\nIn this stage, the raw material is mixed with a suitable binder and water to form a dough &#8211; like consistency. The mixture is then forced through a die, which is a small opening with a specific shape (usually a round hole). As the material passes through the die, it comes out in the form of long, thin cylinders called extrudates.<\/p>\n<p>Our granulation machines are equipped with high &#8211; quality extrusion heads that can handle a wide range of material viscosities. This ensures a smooth extrusion process and consistent extrudate diameter.<\/p>\n<p><strong>Spheronization Step<\/strong>:<br \/>\nThe extrudates are then transferred to a spheronizer. Inside the spheronizer, there&#8217;s a rapidly rotating friction plate. As the extrudates hit the plate, they break into smaller pieces and roll around, gradually forming spherical shapes due to the frictional and centrifugal forces.<\/p>\n<p><strong>Advantages of Extrusion &#8211; Spheronization<\/strong>:<\/p>\n<ul>\n<li>It allows for a high degree of control over the granule size and shape. You can change the die size during extrusion to adjust the initial diameter of the extrudates, and the spheronizing conditions to fine &#8211; tune the final spherical shape.<\/li>\n<li>This method can produce very dense and uniform spherical granules, which is important for applications where consistent product quality is required, such as in pharmaceutical tablets.<\/li>\n<\/ul>\n<h3>3. Spray Drying Spray drying is a method that&#8217;s commonly used when you have a liquid feedstock and you want to turn it into spherical granules.<\/h3>\n<p><strong>The Process<\/strong>:<br \/>\nFirst, the liquid feed (which could be a solution, suspension, or emulsion) is pumped into a spray dryer. Inside the dryer, an atomizer breaks the liquid into tiny droplets. These droplets are then introduced into a hot &#8211; air stream.<\/p>\n<p>As the droplets come into contact with the hot air, the solvent in the droplets evaporates rapidly. This leaves behind solid particles that coagulate into spherical droplets. The spherical shape is a result of the surface tension of the liquid droplets, which tries to minimize the surface area.<\/p>\n<p>Our granulation machines are designed with efficient spray &#8211; drying chambers and high &#8211; performance atomizers. This ensures that the droplets are evenly atomized and the evaporation process is carried out effectively.<\/p>\n<p><strong>Benefits of Spray Drying<\/strong>:<\/p>\n<ul>\n<li>It can produce very fine spherical granules with a narrow particle &#8211; size distribution. This is useful in applications like food flavorings and some high &#8211; tech materials where small particle size and uniformity are crucial.<\/li>\n<li>The process is relatively fast, which allows for high &#8211; volume production.<\/li>\n<\/ul>\n<h3>4. Melt Granulation Melt granulation is a method that uses heat to transform the raw materials into a molten state and then form spherical granules.<\/h3>\n<p><strong>The Procedure<\/strong>:<br \/>\nThe raw material is heated until it melts. This could be a wax, a low &#8211; melting &#8211; point polymer, or a mixture of substances. Once melted, the molten material is forced through a nozzle or a die. As the molten droplets fall, they cool and solidify into spherical granules.<\/p>\n<p>Our granulation machines have precise temperature control systems for the melt &#8211; granulation process. This ensures that the material is heated to the correct temperature and that the cooling process is well &#8211; regulated.<\/p>\n<p><strong>Benefits of Melt Granulation<\/strong>:<\/p>\n<ul>\n<li>It can produce granules without the need for a binding agent. This is beneficial in some industries where the presence of a binder might affect the product&#8217;s properties.<\/li>\n<li>The process can be used to encapsulate substances within the molten matrix, which is useful for controlled &#8211; release applications in pharmaceuticals and agriculture.<\/li>\n<\/ul>\n<h3>5. Fluid &#8211; Bed Granulation Fluid &#8211; bed granulation is a versatile method that can produce spherical granules with different characteristics.<\/h3>\n<p><strong>How It Works<\/strong>:<br \/>\nThe raw powder is placed in a fluid &#8211; bed chamber. Air is blown through the powder from the bottom, making the powder particles &quot;float&quot; or fluidize. A binding agent solution is then sprayed onto the fluidized particles.<\/p>\n<p>As the binding agent wets the particles, they start to stick together. The upward &#8211; flowing air helps the granules to move around and form spherical shapes. The continuous movement within the fluid &#8211; bed also ensures a homogeneous mixing of the particles and the binder.<\/p>\n<p>Our granulation machines have advanced fluid &#8211; bed systems. The air flow rate, temperature, and spray rate can all be precisely adjusted to control the granulation process and produce high &#8211; quality spherical granules.<\/p>\n<p><strong>Advantages of Fluid &#8211; Bed Granulation<\/strong>:<\/p>\n<ul>\n<li>It can handle a wide range of materials, from fine powders to coarse particles.<\/li>\n<li>The process can be easily scaled up for industrial &#8211; scale production.<\/li>\n<\/ul>\n<h3>Conclusion<\/h3>\n<p><img decoding=\"async\" src=\"https:\/\/www.hnmwmequip.com\/uploads\/47002\/small\/rotary-drum-granulatord7fbc.jpg\"><\/p>\n<p>As you can see, there are several methods to produce spherical granules using a granulation machine.
