Requirements for Materials in Biology organic Fertilizer Dryers
Biology organic fertilizer dryers operate at low temperatures. To ensure drying efficiency, finished product quality, and stable fertilizer production machine , specific requirements are placed on the feed state, particle shape, and impurity content. The feed moisture content must be controlled between 30% and 40%. Excessive moisture significantly increases the drying load, easily causing particle sticking, material blockage in the drum, and prolonged material residence time, indirectly affecting the activity of live bacteria. Insufficient moisture results in dry, brittle particles that easily break during turning, increasing powder residue. Particle size should be uniform, ideally with a standard particle size of 2-4mm, avoiding significant size variations. The proportion of fine powder should not exceed 8%, as excessive powder will be lost with the hot air, wasting raw materials and increasing the burden on the dust removal system. Simultaneously, the particles m...
