Considering the health and safety of employees (powdered fertilizers can be inhaled), as well as environmental factors (forming dust), fertilizer manufacturers manufacture fertilizers into powder and crystals. This can better control the use of fertilizers without changing the molecular formula of the product.

When the raw material is a very fine powder, the sample is roughly crushed into a 1-2cm hard film like fertilizer by the instrument through extrusion pressure. Afterwards, the sample was finely crushed and sieved through a screening instrument. Only 50% -80% of the final products meet the required particle size distribution. Smaller particles will continue to be finely ground, while larger particles will need to be re roughly crushed.
