A granulator machine is a piece of industrial equipment that turns fine powder into granules via a set of physical processes that make the particles in the powder stick together. Any undersized granules that come out of the machine are returned to the first stage of the granulation process to be enlarged again. A granulator is also often called a pelletizer and is a common piece of machinery in the compound fertilizer manufacturing industry.
There are many disadvantages to powder and granulation technology has revolutionized production lines in many industries. Granulation machines have been particularly useful to the pharmaceutical industry, as medicine powder can now be compressed into tablets and capsules containing exact dosages.
When it comes to granulating organic fertilizer powder there is a range of different methods that can be used. Some of the most popular granulation methods include wet granulation, ammoniation granulation, compaction, prilling, melt spray granulation, and steam granulation. The granulation methods can work with any type of fine powder. Wet granulation is used when the powder requires the addition of a binding agent to facilitate granule formation.
There and many different types of fertilizer pelletizing equipment in the marketplace for making organic NPK compound fertilizer pellets. Some of the equipment available includes rotary drum granulating machines, disc pan granulators, and double roller press granulators. It is important to choose equipment designed to work best with powder you need to granulate.
Pan granulators use centrifugal force to pelletize powders. They are a popular type of fertilizer granulator as they are inexpensive and easy to maintain. A powder drum pelletizer is more suited for large scale production than disc pan granulators. If you plan to run a large-scale fertilizer manufacturing business, a power drum granulating machines is likely to be a wise investment. The TDZGZ-3210 model, for example, has a capacity of 30 tons per hour.
The great thing about double roller extrusion granulating machines is that they use the dry granulation method. This means that businesses don’t need to invest in any drying equipment, as the moisture content of granules produced is low. A double roller extrusion granulator is ideal for a small-scale production line when paired with a screening machine. A screening machine removes unqualified granules from the end product, so they can be sent back for re-granulating. The granule diameter the TDJZ-2T model, for example, produces ranges from 3mm to 10mm.
There are several reasons why it can be beneficial to turn powder into granules. For instance, when it comes to storage and transportation, pellets are much more convenient. Powder can easily spill during transportation and piles of storage powder can be blown away. Granules also have a longer quality guarantee and can last over 2 years in storage.
When buying any type of powder granulating machine there are many other pieces of equipment that you also need in order to set up an efficient production line. Some of the equipment you might need includes batching systems, mixing equipment, crushing facilities, screening machines, coating equipment and packing machine.
