Operation precautions of NPK fertilizer granulation coatingPosted by Fertilizer Machine on November 9th, 2020 In the NPK fertilizer manufacturing process, a coating process is added to make a slow-release fertilizer. Slow-release fertilizer is also called controlled-release fertilizer. The release rate of nutrients in fertilizers can be controlled to a certain extent for continuous absorption and utilization by crops. After the fertilizer is coated, it can reduce the loss of fertilizer nutrients, especially nitrogen, in the soil. Can reduce the frequency of fertilization, save labor and cost. To increase crop yield and income, the application of slow-release fertilizer can improve crop resistance to disease and lodging. Precautions for the operation of fertilizer coating1. Do not remove the protective device when the coating machine is running. The production capacity of fertilizer drum granulation process is 1-20T / h, and the application scope of fertilizer granule coating machine is: peat, sludge, chicken manure, livestock manure, lignite, filter sludge of sugar mill, papermaking sludge, wine, straw, bean dregs, etc. Like it?
