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.

A double shaft mixer is an efficient mixing device characterized by two independent and usually opposite rotating mixing shafts, which can achieve deep mixing and uniform distribution of materials. This type of mixer is widely used in industries such as chemical, pharmaceutical, food, and building materials, and is particularly suitable for handling high viscosity materials, materials containing solid particles, and situations that require fine mixing.

Vertical mixer is a common material mixing equipment in industrial production, characterized by vertically arranged mixing containers, suitable for mixing various dry powders, wet materials, slurries, and high viscosity materials. Vertical mixers have a wide range of applications in industries such as chemical, food, pharmaceutical, and building materials, especially suitable for mixing small and medium batches of materials.

Horizontal mixer is a material mixing equipment widely used in industries such as chemical, pharmaceutical, food, building materials, etc. Its main feature is that the mixing container is horizontally arranged, which can effectively handle the mixing of large capacity, high viscosity or materials containing solid particles, especially suitable for mixing operations that require long-term mixing or high uniformity.
