Installation site of controlled-release fertilizer equipment for customers in Semarang, Indonesia

At the installation site of controlled-release fertilizer equipment for customers in Sanbaolong, Indonesia, the customer is a manufacturer of organic fertilizers for many years and has advanced equipment advantages in the local fertilizer market. The fertilizer produced is in short supply. In order to improve production technology, new controlled-release fertilizer equipment has been installed

Controlled Release Fertilizer (CRF) equipment is a professional mechanical system used for producing CRF fertilizers. Its core function is to form a special coating or structure on the surface of fertilizer particles through physical, chemical, or biological means, achieving precise regulation of nutrient release rate, matching it with crop growth cycle, improving fertilizer utilization efficiency, and reducing environmental pollution.
Basic Definition and Classification
Controlled release fertilizer equipment is mainly divided into two categories:
Complete set of production equipment: According to the definition of GB/T 31201-2014 standard, it is an automated process equipment for producing compound fertilizer (slow-release) through main processes such as automatic batching, crushing, granulation, drying, cooling, screening, coating, quantitative packaging, and dust removal
Core coating equipment: key equipment to realize controlled release function, including drum coating machine, fluidized bed coating machine, spray coating equipment, etc

Typical Process of Controlled Release Fertilizer Production Line
Raw material processing: metering, mixing, and crushing of basic fertilizers (nitrogen, phosphorus, potassium, etc.), coating materials (resins, sulfur, etc.), and additives
Granulation: Prepare basic fertilizer granules through methods such as rotary drum/disc/extrusion
Drying and cooling: removing moisture, lowering temperature, and improving particle strength
Screening: Screen particles that meet the specifications, return non-conforming products for re granulation
Encapsulation: The core controlled release process forms a semi permeable or impermeable coating on the surface of particles
Secondary drying and cooling: solidify the coating layer to ensure stable controlled release effect
Finished product packaging: quantitative packaging for easy storage and transportation
Key technical characteristics of controlled-release fertilizer equipment
Precise control: The computer control system precisely adjusts parameters such as temperature, flow rate, and pressure to ensure uniform and consistent coating thickness and release rate
Continuous production: achieve industrialization, scale, and continuous coating to improve production efficiency
Multi functional adaptation: capable of producing controlled-release fertilizers with different release cycles (30-120 days) to meet the needs of different crop growth stages
Environmental protection and energy conservation: reduce fertilizer loss, lower environmental pollution, and meet the requirements of sustainable development in modern agriculture
Difference from ordinary compound fertilizer equipment
The core difference between controlled-release fertilizer equipment and ordinary compound fertilizer equipment is the addition of a professional coating system, which is the key to achieving nutrient controlled-release function. The ordinary compound fertilizer production line lacks this link and cannot accurately control the nutrient release rate.
applied value
The controlled-release fertilizer produced by controlled-release fertilizer equipment has the following advantages:
Improve fertilizer utilization efficiency (up to 2-3 times that of ordinary fertilizers)
Reduce the frequency of fertilization (from 3-4 times to 1-2 times)
Reduce labor costs
Reduce nutrient loss and pollution of soil and water bodies
Realize stable crop growth, improve yield and quality
