Also known as a pan pelletizer, a pan granulator is a drum-like machine that turns organic fertilizer powder or compound fertilizers into granules. It looks very similar to a huge pan, hence the name of pan granulator. This machine needs to be used together with other fertilizer making machines, as it is part of the standard fertilizer production line. If you want to make organic fertilizer and to either use it for your own crops or sell it to other farmers, you’ll need to find the ideal way to store and pack it. As pellets or granules are the universally agreed standard, that’s also your best choice.
When choosing your fertilizer pan granulator, you need to take into consideration a few things that have a direct influence on the effectiveness of this machine. First of all, you have to think about the purpose of your production plant. Do you only need to pelletize organic fertilizer or you’d like to use your equipment also to pelletize compound fertilizers? Would you rather invest in a device that can pelletize a wider range of powders? Would you need to turn animal waste into fertilizer, as well? You should take your time and analyze your business needs in great depth to ensure that you buy the right type of equipment to suit your specific fertilizer granulation requirements.
One of the most important features pf this type of machine is the granulation rate. This number should be as close to 100% as possible, as it is in your best interest to turn the whole amount of powdery material into pellets. However, a rate of 100% isn’t possible. Machines that provide a 95% granulation rate are considered to be extremely effective. This is as good as you can get, so you should be pleased with a machine that turns over 90% of your powder into pellets.
The size of the disk pan is another technical specification to carefully consider when shopping around for the best fertilizer pan type granulator. The smallest machine you can get has a disk pan of only 500 mm diameter. This small size suits smaller businesses or farms that don’t have a generous amount of storage space. Such machines are known as lab granulators and they offer the convenience of space. However, if you intend to make organic fertilizer pellets on a larger scale, you’ll need to choose a much bigger machine. There are pan granulators that feature a diameter of 3600 mm. Such machines are able to process up to 6t of powder per hour.
The granulation method is another detail that will influence your choice. There are machines that employ wet granulation method and others that use dry granulation. Wet granulation is better, as it is more environmentally-friendly than dry granulation.
Choosing the ideal fertilizer pan granulator is a matter of determining your production needs, in terms of materials to be pelletized and processing volume capabilities. Furthermore, you should assess all your available options, in order to invest in the best equipment for your fertilizer production line.
