Organic fertilizer drum coating machine is a specialized equipment used to uniformly wrap coating agents (such as anti caking agents, slow-release layers, etc.) on the surface of organic fertilizer particles. Its core working principle is based on the combination of physical rotation and spraying/powder coating technology. According to authoritative public information, its work process can be summarized as follows:

Key points of working principle

-Rotary cylinder drive: The main motor drives the active shaft to rotate through a pulley and reducer. The split gear on the active shaft meshes with the large gear ring fixed on the body, thereby driving the entire cylinder to slowly rotate.

-Rolling flow of materials: Organic fertilizer particles enter the inclined or horizontally installed cylinder from the feeding end, and are continuously lifted and overturned by the internal plate during the rotation of the cylinder, forming a uniform flow layer and providing basic conditions for the coating.

-Application of coating agent:

-Liquid coating: Spray coating liquid (such as oil, resin, etc.) evenly onto the surface of particles through a spray system;

-Powder coating: The powder coating agent is evenly spread onto the particles through a powder coating machine.

-Friction and wrapping: During the rolling process, particles rub and collide with each other, causing the coating agent to evenly adhere and cover the surface of each particle.

-Drying/curing assistance (some models): equipped with a hot air system or induced draft fan to accelerate the drying or curing of the coating agent, forming a stable and firm coating layer.

Features of the equipment

-Material corrosion resistance: The lining inside the cylinder is usually made of polypropylene or acid resistant stainless steel, which is suitable for acidic and alkaline environments.

-Strong process adaptability: supports dry powder, liquid or composite coating methods, and can customize trace element addition functions.

-Modular structure: The whole machine includes a bracket, transmission, large gear ring, rolling belt, main engine and other parts, which are easy to install and maintain.

This device is widely used for anti caking treatment of granular materials such as organic fertilizers, compound fertilizers, and biological fertilizers, significantly enhancing the commercial value and effectiveness of fertilizers.
