Organic fertilizer screening machine is a type of equipment used to separate finished organic fertilizer products from the raw materials. The machine is typically used after the granulation process to separate the granules from the oversized and undersized particles. The screening machine works by using a vibrating screen with different sized sieves to separate the organic fertilizer granules according to their size. This ensures that the final product is of a consistent size and quality. Additionally, the screening machine can be used to remove any impurities or foreign materials that may be present in the finished product.
