Fertilizer Grinding

Fertilizers are used in agriculture to speed the growth of plants and increase their yield by supplying the plants with the main essential nutrients NPK (nitrate, phosphorus and potassium). Traditional fertilizers include natural products such as manure or chalk, while nowadays mostly the organic fertilizer Urea as well as chemical products or mineral fertilizers (NPK-fertilizers) such as Ammonium nitrate, -sulphate and -phosphate are applied. Grinding fertilizers is used mostly as a granulation step. Bauermeister Mills are widely used for grinding Urea, however Ammonium nitrate, sulphate as well as other chemical fertilizers can be granulated as well. A typical required fertilizer particle size is in granules from 2 to 4 mm. Bauermeister Roller Mills provide the ideal technology for achieving this granulation while generating a minimized amount of dust. If a very fine distribution is required, Bauermeister Universal Mills are the optimal choice.
