Fertilizer ingredients can be processed with Sturtevant’s jet mills, impact mills and pin mills and are a great resource when trying to reduce those ingredients in particle size. Sturtevant’s mills are capable of achieve various degrees of impact and agitation grinding and classifying those materials.

Fertilizer materials are air classified according to size or density. Air classification provides the most effective means for separating a product from a feed stream, for dedusting, or when used in conjunction with grinding equipment for increasing productivity.

Fertilizers consist of a large number of natural and synthetic materials including manure, nitrogen, phosphorus, and potassium compounds.

These products air classify and size reduce fertilizer ingredients:
