For fertilisers in a solid aggregate condition, as a rule mineral solid fertilisers, the specific surface plays an important role. Depending on this value, a different behaviour of the fertiliser appears after spreading. Important points to test are particle size and macro-structure of the single grains. During a classic screening analysis the granulate from the rotary kiln or pelletising plate are partially destroyed. Moreover for assessing macrostructure, an additional test is necessary. The HAVER CPA 2-1 provides a complete analysis and all values are available.

The HAVER CPA 2-1 offers a rapid and uncomplicated solution for evaluating most mineral, solid fertilisers. The results also offer additional characteristic values and measurement parameters that characterise the material beyond the known customer specifications, and thus provide a solid basis for process monitoring. Especially for energy-intensive processes an online solution can be considered.
