Slow-release compound fertilizer can not only replenish the nutrients needed for crop growth in time, but also provide the nutrients needed for crop growth for a long time, so slow-release compound fertilizer is also one of the best-selling fertilizers. According to the relevant data, the addition of combined inhibitors in the NPK fertilizer production
line can improve the utilization rate of nitrogen by 8% to 12%, and can increase the nitrogen absorption and biomass of crops.
Combined inhibitors and nitrogen fertilizer mixed use, can extend the fertilizer efficiency period, improve crop yield, about 1/4 of nitrogen can be maintained in the soil, as part of the soil nitrogen fertility.
The production process for controlled release compound fertilizer equipment is as follows:
Envelope material melting device: Continuous rapid melting for thermally sensitive materials, computer-controlled continuous and stable to provide accurate coating material fluid spraying to spray systems.
Coating film drum: by the computer to control the carrier flow, in the drum once complete fertilizer preheating and coating material spraying, the formation of a certain thickness of the coating when spray sealants, regulators, etc. to improve product performance. Cooling drum: The special design of cooling drum greatly improves the cooling efficiency, minimizes the friction between the coating particles during the cooling process, effectively reduces the generation of dust, and improves the smoothness of the surface of the film particles.
Huaqiang Heavy Industries specializes in manufacturing fertilizer granulator machine
, coating machine, and dryer machine.
Advantages of slow release of fertilizer: With good appearance quality, uniform film, strong wear resistance, membrane degradation can provide sulfur nutrition, non-polluting, in line with the requirements of environmentally friendly fertilizer. A large number of field fertilizer tests have proved that compared with non-encapsulation fertilizer, the same level of economic input can increase production by 6-10%. At the same yield level, the amount of fertilizer applied can be reduced by 1/3, and fertilizer utilization can be increased by 10 percentage points.
The scope of application of slow release fertilizer: can produce large-particle urea or crop-specific fertilizer as the carrier of controlled release fertilizer. Slow, controlled release fertilizer its variety and processing forms, the current popular internal matter and outsourcing of the two, the endogenous added endoenzymes such as urease inhibitors and nitrification inhibitors, or polysytine, etc. , outsourced is sulfur wrap, resin wrap, and some inorganic films such as some phosphates, and some chemically controlled release such as urine formaldehyde, etc. Production processes vary.
