Suitable for fermented manure and wet materials In organic fertilizer production, fermented and decomposed materials often face a challenging situation: their moisture content remains high, typically between 25% and 40%. Within this moisture range, the material exhibits a certain degree of stickiness and toughness, easily causing blockages, wall adhesion, and even motor burnout in conventional...

Basic Principles of Raw Material Selection The core of bio-organic fertilizer lies in “organic matter + functional bacteria.” Therefore, there are two basic thresholds for raw material selection: organic matter content and restrictions on harmful substances. Suitable organic raw materials include livestock and poultry manure (chicken manure, cow manure, pig manure, sheep manure), agricultural...

Basic Principles of Aerobic Fermentation: The essence of composting fermentation is the decomposition of organic matter in organic materials by microorganisms under aerobic conditions. During decomposition, microorganisms release heat, gradually raising the pile temperature to 55-70℃. This temperature range effectively kills pathogens and weed seeds while accelerating the maturation of organic...

Common NPK Granulator Types In NPK compound fertilizer production, the granulation process directly determines the particle strength, appearance, and applicability of the finished product. Currently, there are three main types of granulation equipment on the market: Drum Granulator:This is the most widely used NPK granulation equipment. Material is agglomerated into spheres within a rotating drum...

In the core process of fertilizer production—granulation—rotary drum granulators and extrusion granulators are two mainstream and technologically distinct types of high-efficiency equipment. For companies planning to invest in or upgrade their production lines, making a wise choice between these two directly impacts future product positioning, operating costs, and market competitiveness. These...

Designed Specifically for Small-Scale Production For small-scale organic fertilizer plants, livestock farm-affiliated fertilizer workshops, or family farms with an annual output of several hundred to two or three thousand tons, equipment investment costs and production flexibility are often more important than single-machine capacity. The cage crusher is designed to meet this need. With its...

Raw Material Pretreatment Process: The raw material pretreatment stage in organic fertilizer production encompasses the entire conversion process from raw organic waste to granulizable powder. The core process is: fermentation and turning → crushing → mixing → granulation. These four processes are interconnected, each with corresponding specialized equipment, collectively determining the quality...

Basic Principles of Aerobic Fermentation: The essence of organic fertilizer fermentation is the process of decomposing organic matter using aerobic microorganisms. Under sufficient oxygen conditions, microorganisms multiply rapidly, breaking down large organic molecules in manure and straw into smaller humic molecules, while simultaneously releasing heat to raise the temperature of the compost...

What is Blended Fertilizer (BB Fertilizer)? BB fertilizer, or Bulk Blending Fertilizer for short, is a compound fertilizer made by physically mixing basic fertilizer granules such as nitrogen, phosphorus, and potassium according to the crop’s needs. Unlike chemically granulated compound fertilizers, BB fertilizer retains the original particle shape of each raw material, making the nutrients...

Production Line Structure and Process Flow: The roller press granulator production line uses a dry process as its core, mainly including crushing, batching and mixing, extrusion granulation, crushing and screening, and coating packaging. Compared with traditional drum granulation, its biggest advantage is that it eliminates the need for drying and cooling processes, resulting in a...
