Comment produire des granules d'engrais de taille uniforme

 Begin with raw materials that make uniform particle size fertilizer. Use fertilizer grinder to crush compost or chemical materials into homogenous powder.  As inconsistent particle sizes in the initial mix can lead to varied granule sizes. Uniformity in raw materials helps in achieving uniformity in the finished granules.

En outre, the right moisture content is also essential for successful granulation of fertilizer. It allows powder to bind together effectively without becoming too wet or dry. Moisture levels typically range from 10-30%, depending on the granulation technology. Le dry granulation machine require a below 10% moisture while wet granulation equipment needs a 20%-40% water content.

Calibrating your equipment for making fertilizer granules regularly. Whether you use pan granulators, rotary drum pelletizers or extrusion granulation machines. Parameters such as the disc angle, rollers gap, rotary speed and amount of binder solution, etc.. Parce que, after a long period of fertilizer granulation equipment use, the equipment may has nuance. So you need to adjust it to ensure that you can produce fertilizer granules with with uniform size.

After initial granulation of fertilizer materials, use a rotary screener or similar sieving equipment to separate the organic or NPK fertilizer granules by size. The oversized and undersized granules should be separated from the correctly sized granules. The off-size granules can then be crushed and recycled back into the granulation process to be reformed into the desired size.
