An organic fertilizer shaker, also known as a sieve or screen, is a machine used in the production of organic fertilizers to separate and classify different-sized particles. It typically consists of a vibrating screen or sieve with different-sized mesh openings to allow smaller particles to pass through and larger particles to be retained for further processing or disposal. The shaker can be used to remove debris, clumps, and other unwanted materials from the organic fertilizer before packaging or distribution. The shaker is an essential piece of equipment for ensuring the quality and consistency of organic fertilizers.
