As a supplier of Rotary Tablet Presses, I&#8217;ve seen my fair share of issues that customers run into. In this blog, I&#8217;m gonna talk about some common problems with Rotary Tablet Presses and how you can solve them. <a href=\"https:\/\/www.lanphanindustry.com\/tablet-press\/rotary-tablet-press\/\">Rotary Tablet Press<\/a><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.lanphanindustry.com\/uploads\/47438\/small\/small-freeze-dryer-for-home-use35bbe.jpg\"><\/p>\n<h3>1. Capping and Lamination<\/h3>\n<p>One of the most common issues is capping and lamination. Capping happens when the top or bottom of the tablet separates from the main body, while lamination is when layers within the tablet start to delaminate.<\/p>\n<h4>What causes it?<\/h4>\n<ul>\n<li><strong>Poor powder properties<\/strong>: If the powder has low cohesiveness, it won&#8217;t stick together well during compression. This could be due to factors like particle size distribution, moisture content, or the chemical composition of the powder.<\/li>\n<li><strong>Incorrect compression settings<\/strong>: Over &#8211; compression can force air out of the powder too quickly, causing the tablet to cap. On the other hand, under &#8211; compression won&#8217;t hold the tablet together properly.<\/li>\n<li><strong>Worn tooling<\/strong>: If the punches and dies are worn out, they won&#8217;t compress the powder evenly, leading to capping or lamination.<\/li>\n<\/ul>\n<h4>How to solve it?<\/h4>\n<ul>\n<li><strong>Adjust the powder characteristics<\/strong>: You can try adding binders to increase powder cohesiveness. Also, make sure the moisture content is within the appropriate range. Sometimes, granulating the powder can also improve its compressibility.<\/li>\n<li><strong>Optimize compression settings<\/strong>: Experiment with different compression forces and speeds. You may need to lower the compression force if you suspect over &#8211; compression. Use a tablet press with adjustable settings to fine &#8211; tune the process.<\/li>\n<li><strong>Replace worn tooling<\/strong>: Regularly inspect your punches and dies. If they show signs of wear, like cracks or excessive smoothness, replace them immediately. This will ensure even compression and reduce the risk of capping and lamination.<\/li>\n<\/ul>\n<h3>2. Weight Variation<\/h3>\n<p>Another problem that often pops up is weight variation in tablets. Each tablet should have a consistent weight for accurate dosing, but sometimes, there can be significant differences from one tablet to another.<\/p>\n<h4>What causes it?<\/h4>\n<ul>\n<li><strong>Uneven powder flow<\/strong>: If the powder doesn&#8217;t flow smoothly into the die cavities, some cavities will get more powder than others, leading to weight variation. This can be due to issues like clogged feeders or improper powder hopper design.<\/li>\n<li><strong>Worn or damaged components<\/strong>: The feeding system, such as the feeder screws or paddles, may be worn out. This can disrupt the powder flow and result in inconsistent tablet weights.<\/li>\n<li><strong>Inadequate tablet press calibration<\/strong>: If the tablet press is not properly calibrated, it may not dispense the correct amount of powder into each die cavity.<\/li>\n<\/ul>\n<h4>How to solve it?<\/h4>\n<ul>\n<li><strong>Improve powder flow<\/strong>: Check the feeder for any blockages and clean it regularly. You can also add anti &#8211; static agents to the powder to reduce sticking. Consider modifying the powder hopper design to ensure better powder flow. For example, adding a vibrator to the hopper can help keep the powder moving.<\/li>\n<li><strong>Replace worn components<\/strong>: Inspect the feeding system components regularly. Replace any worn or damaged parts, such as feeder screws or paddles, to ensure consistent powder delivery.<\/li>\n<li><strong>Calibrate the tablet press<\/strong>: Follow the manufacturer&#8217;s instructions to calibrate the tablet press. This may involve adjusting the filling depth, the rotation speed of the feeder, or other relevant parameters. Regular calibration will help maintain consistent tablet weights.<\/li>\n<\/ul>\n<h3>3. Chipping and Breaking<\/h3>\n<p>Chipping and breaking of tablets are also common problems. Tablets may chip at the edges or break into pieces during the compression process or handling.<\/p>\n<h4>What causes it?<\/h4>\n<ul>\n<li><strong>Brittle tablets<\/strong>: The formulation of the tablet may result in a brittle structure. This could be due to the use of certain excipients or improper granulation.<\/li>\n<li><strong>High ejection force<\/strong>: If the tablet press ejects the tablets with too much force, it can cause chipping or breaking. This may be because of a misaligned ejection system or worn punches.<\/li>\n<li><strong>Handling issues<\/strong>: Rough handling during the tablet collection or packaging process can also lead to chipping and breaking.<\/li>\n<\/ul>\n<h4>How to solve it?<\/h4>\n<ul>\n<li><strong>Modify the tablet formulation<\/strong>: Try adding lubricants or plasticizers to the tablet formulation to make it less brittle. You can also adjust the granulation process to improve the strength of the tablets.<\/li>\n<li><strong>Adjust the ejection system<\/strong>: Check the alignment of the ejection system and make sure the punches are not worn. If necessary, adjust the ejection force to a level that will safely remove the tablets without causing damage.<\/li>\n<li><strong>Improve handling procedures<\/strong>: Train your staff on proper tablet handling techniques. Use gentle handling equipment during the collection and packaging processes to minimize the risk of chipping and breaking.<\/li>\n<\/ul>\n<h3>4. Double &#8211; punching<\/h3>\n<p>Double &#8211; punching occurs when the tablet press punches the same die cavity more than once, resulting in an over &#8211; compressed tablet.<\/p>\n<h4>What causes it?<\/h4>\n<ul>\n<li><strong>Electrical or mechanical malfunctions<\/strong>: There could be issues with the tablet press&#8217;s control system, such as a faulty sensor or a problem with the motor. Mechanical problems, like a loose or worn &#8211; out drive belt, can also cause double &#8211; punching.<\/li>\n<li><strong>Operator error<\/strong>: Sometimes, operators may accidentally activate the tablet press multiple times or not follow the correct operating procedures.<\/li>\n<\/ul>\n<h4>How to solve it?<\/h4>\n<ul>\n<li><strong>Check and repair the control system<\/strong>: Inspect the sensors, relays, and other electrical components of the tablet press. Replace any faulty parts and ensure that the control system is functioning properly.<\/li>\n<li><strong>Fix mechanical issues<\/strong>: Tighten any loose drive belts or replace worn &#8211; out parts. Regular maintenance of the mechanical components can prevent double &#8211; punching problems.<\/li>\n<li><strong>Train operators<\/strong>: Provide comprehensive training to operators on the correct use of the tablet press. Make sure they understand the operating procedures and are aware of the potential risks of double &#8211; punching.<\/li>\n<\/ul>\n<h3>5. Sticking of Tablets to Punches<\/h3>\n<p>Tablets sticking to the punches is a pesky problem that can slow down production and affect tablet quality.<\/p>\n<h4>What causes it?<\/h4>\n<ul>\n<li><strong>High moisture content<\/strong>: If the powder has a high moisture content, it can stick to the punches during compression. This is especially true if the punches are not properly lubricated.<\/li>\n<li><strong>Lack of lubrication<\/strong>: Insufficient lubrication on the punches can cause the tablets to adhere to them. The lubricant helps reduce friction between the tablet and the punch surface.<\/li>\n<li><strong>Poor punch surface finish<\/strong>: If the punches have a rough surface finish, it can increase the likelihood of tablets sticking. This could be due to corrosion or wear of the punches.<\/li>\n<\/ul>\n<h4>How to solve it?<\/h4>\n<ul>\n<li><strong>Control moisture content<\/strong>: Ensure that the powder is properly dried before using it in the tablet press. You can use a dehumidifier in the production area to maintain a low &#8211; humidity environment.<\/li>\n<li><strong>Add lubricant<\/strong>: Use an appropriate lubricant and apply it correctly to the punches. You can also adjust the amount of lubricant in the tablet formulation if necessary.<\/li>\n<li>** Polish or replace punches**: If the punches have a rough surface, you can try polishing them to improve the surface finish. If they are severely worn or corroded, replace them with new punches.<\/li>\n<\/ul>\n<p>In conclusion, while Rotary Tablet Presses can face several common problems, most of them can be solved with proper maintenance, adjustment of settings, and attention to the tablet formulation.
