The Malaysian customer contacted our company through the internet to install and debug the drum coating machine. The drum coating machine has become a core equipment for fertilizer enterprises to improve product quality and enhance market competitiveness. From anti caking to slow-release, from appearance optimization to functional enhancement, its application value runs through the entire process of fertilizer production. Choosing appropriate equipment configuration and process solutions can help customers achieve triple benefits of product premium, cost reduction, and environmental compliance, helping enterprises seize the opportunity in the transformation of green agriculture.
The rotary drum coating machine (also known as rotary coating machine or drum coater) is a core equipment in the deep processing of fertilizers. Through an inclined rotating drum and precision spraying system, it uniformly coats functional layers on particle surfaces, solving problems such as caking, moisture absorption, and nutrient loss, while enhancing product added value and market competitiveness. Widely used in production lines for compound fertilizers, organic fertilizers, bio-fertilizers, and slow-release fertilizers, it is an essential equipment for large-scale fertilizer enterprises.
Core Application Fields & Scenarios
1. Compound/Mixed Fertilizer Industry (Accounting for ~85%)
- Anti-caking Coating: Coating with paraffin, mineral oil, diammonium phosphate, etc., to isolate air and moisture, solving the storage caking problem of high-concentration compound fertilizers (e.g., NPK ≥ 45%). A large-scale compound fertilizer plant reduced the caking rate from 35% to below 5% after application.
- Appearance Optimization: Improving particle brightness and uniformity to enhance market attractiveness, with a premium of 50-100 RMB per ton.
- Nutrient Regulation: Adding trace elements (zinc, boron, iron, etc.) to produce customized formula fertilizers for different crops.
2. Organic/Bio-organic Fertilizer Industry (Growth Rate +15%)
- Microbial Inoculant Coating: Protecting beneficial bacteria such as Bacillus subtilis and Bacillus amyloliquefaciens, increasing bacterial survival rate by 30%+ and extending product shelf life.
- Humic Acid/Amino Acid Coating: Enhancing organic fertilizer stability, reducing nutrient loss, and improving soil improvement effects.
- Deodorization: Coating with plant essential oils to reduce odors, improving storage and application experience.
3. Slow/Controlled-release Fertilizer Industry
- Polymer Coating: Producing sulfur-coated urea and resin-coated compound fertilizers to achieve 3-6 months of slow nutrient release, reducing fertilization frequency and increasing utilization rate by 30%+.
- Urea-formaldehyde/Monoammonium Phosphate Coating: Forming slow-release layers through chemical reactions, suitable for field crops, cash crops, and landscape applications.
4. Other Special Applications
- Feed Additives: Coating vitamins and probiotics to prevent oxidation and deliquescence, applicable to large-scale breeding enterprises.
- Industrial Particles: Such as refractory materials and catalyst carriers, improving fluidity and wear resistance.
- Saline-alkali Soil Special Fertilizers: Coating modifiers to reduce soil salinity damage and enhance crop stress resistance.
