BB fertilizer, also known as Bulk Blended Fertilizer, is a compound fertilizer made by physically mixing different types of fertilizer raw materials, usually without involving chemical reaction processes. The BB fertilizer mixer is a specialized equipment used for mixing fertilizer raw materials. Its design aims to ensure that various fertilizer raw materials can be evenly mixed, thereby producing BB fertilizer products with stable quality and balanced nutrition.
The structure and composition of a BB fertilizer mixer may vary depending on the specific model and manufacturer, but typically includes the following main parts:
Mixing drum: This is a closed space where the mixing process occurs, designed in a cylindrical or U-shaped shape to ensure uniform distribution of materials during the mixing process.
Mixing device: It consists of a mixing shaft and mixing blades installed on it. Common blade types include paddle type, spiral belt type, etc., and can be selected according to mixing requirements.
Drive system: including motor and reducer, providing power for the mixing device.
Feeding and discharging system: The feeding port is used for adding raw materials, and the discharging port or valve is used for discharging mixed fertilizers.
Control system: used to monitor and control parameters such as mixing speed and mixing time, ensuring the accuracy of the mixing process.
Support and frame: Provide stable support for the mixer to ensure its stability during the mixing process.
The working principle of the BB fertilizer mixer is based on the rotation of the mixing device inside the mixing drum, which mixes different types of fertilizer raw materials through the mixing blades:
Feed: Various fertilizer raw materials are added to the mixing drum from the feed inlet.
Mixing: The motor drives the stirring shaft to rotate, and the stirring blades shear, roll, and diffuse the raw materials during the rotation process, achieving uniform mixing of the raw materials.
Discharge: The evenly mixed BB fertilizer is discharged from the discharge port or discharge valve, usually sent to the packaging equipment through a conveyor belt or pneumatic conveying system.
Uniform mixing: designed for processing fertilizer raw materials to ensure uniform distribution of various components and produce stable quality BB fertilizer.
Large processing capacity: suitable for large-scale production and capable of handling a large amount of fertilizer raw materials.
Simple structure: relatively easy to operate and maintain, suitable for agricultural and fertilizer production environments.
Easy to clean: The design of the mixing drum and mixing device is easy to clean to avoid cross contamination of raw materials between different batches.
Strong adaptability: able to handle fertilizer raw materials of different properties, including solid particles and powders.
