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.
Pan granulator is a good choice for making granulated organic 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
Disc pan granulator is 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.
Granulated fertilizers are so much easier and cheaper to handl
e 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 producing 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.
