The manure arrives in the DFP from the mixing tank. In the steps Dewatering, Filtration and Pressing, the thick fraction is separated from the liquid part.
A robust machine made of stainless steel and a guaranteed long life.
The separator contains a conical auger that moves the product to the back and squeezes the moisture out. The sieve becomes finer as the pressure increases (at the back of the press) to ensure that the thin fraction contains minimal dry matter.
Separating manure is a conscious choice. The ultimate goal is to obtain an end product with a high phosphate content and a low volume in order to keep sales costs as low as possible. In order to achieve a high separation efficiency for phosphate, a manure separator was chosen in combination with a polymer (clotting agent) additive. A phosphate yield of >90% can therefore be achieved.
The solid fraction has a dry matter content of approximately 30%. Important for the next steps is a low dry matter content in the thin fraction. If the content is too high, the processing efficiency decreases and the percentage of mineral concentrate increases.
