Fertilizer Processing Hammer Mills

Size reduction is essential for controlling the successful spread of fertilizer. Hammer mills designed for the fertilizer industry can help dramatically improve the uniform consistency of particles so that plants absorb them at a quick and healthy rate.


Pulva is an all-in-one solutions provider for light- and heavy-duty fertilizer processing, from plant testing to full-scale production.

Particle Size Reduction in the Fertilizer Industry


Smaller particles, or nanoparticles, are a more efficient way for plants to break down and absorb nutrients. The smaller the particle, the faster it breaks down and enters the solution, otherwise known as the dissolution rate. As particles become smaller, they have a greater surface area per unit volume ratio.


Another important factor to consider is that the size of a particle has an exponential effect on the spread width. The larger the particle, the further it is able to be thrown by a spreader. The risk of uneven distribution and segregation increases when there is a large particle size variation within the fertilizer.


It's vital to use a size reduction mill for fertilizer processing to control particle size distribution, and in turn, to control the spread and chemical nutrients delivered to plants.
