Features of compound fertilizer production process equipment:
Coating material melting device: suitable for continuous rapid melting of heat-sensitive materials, computer-controlled can continuously and stably provide accurate coating material fluid to the spraying system.
Coating coating drum: The flow rate of the carrier is controlled by the computer, and the preheating of the fertilizer and the spraying of the coating material are completed in the drum at one time. When a certain thickness of coating is formed, sealants, regulators, etc. are sprayed to improve product performance.
Cooling drum: The special design of the cooling drum greatly improves the cooling efficiency, minimizes the friction between the coated particles during the cooling process, effectively reduces the generation of dust, and improves the surface smoothness of the coated particles.
Compound fertilizer features:
(1) Total nutrient content 36
(2) The controlled release period of nutrients is between 40 and 90 days
(3) Fertilizer particles 3mm
The advantages of compound fertilizer
With good appearance quality, uniform coating and strong wear resistance, the membrane can provide sulfur nutrition after degradation, no pollution, and meets the requirements of environmentally friendly fertilizers. After a large number of field fertilizer efficiency tests, it has been proved that compared with non-coated fertilizers, the yield can be increased by 6-10% at the same economic input level. At the same yield level, the fertilizer application amount can be reduced by 1/3, and the fertilizer utilization rate can be increased by 10 percentage points.
Ecological and environmental benefits
It can effectively reduce the nitrate content of chemical fertilizers in groundwater, reduce the eutrophication of surface water caused by water source pollution, and help improve the safety and quality of agricultural products, prevent and control input pollution. The ecological and environmental benefits are extremely significant.
Scope of application of compound fertilizer
It can produce controlled-release fertilizers with large particles of urea or crop-specific fertilizers as carriers. There are various types and processing forms of slow and controlled-release fertilizers. At present, there are two popular types of endoplasmic and outsourcing. The endoplasmic is added with endoplasmic agents such as urease inhibitors and nitrification inhibitors, or polyaspartic acid. Outsourced ones include sulfur envelopes, tree ester envelopes, and some inorganic envelopes such as some phosphates, as well as some chemical controlled-release fertilizers such as urine formaldehyde. Production processes are different.
