What is a Static Batching System? A multi-bin single-scale static batching system is the most widely used weighing and batching solution in BB fertilizer and NPK blended fertilizer production lines. Simply put, it consists of multiple raw material bins and a high-precision weighing scale hopper, completing the batching process by weighing the materials sequentially. Unlike continuous...

The Value of the Coating Process In organic fertilizer production lines, coating is often the final “finishing touch” after granulation, drying, cooling, and screening. Its task is not to alter the fertilizer’s internal nutrients, but to form a protective film on the granule surface, thereby significantly improving the granules’ appearance, storage properties, and application performance. A...

Main Model Introduction The organic fertilizer granulator series includes various equipment designed for the characteristics of fermented organic materials. The three most common main models are as follows: Disc Granulator: The simplest in structure, consisting of an inclined disc, scraper, and drive unit. The material rotates within the disc, while a suitable amount of water or binder is...

What is an NPK Blender? The NPK blender is a core piece of equipment in BB fertilizer (bulk blended fertilizer) production lines, primarily used for the physical mixing of basic fertilizer granules such as nitrogen, phosphorus, and potassium in a set ratio. Unlike traditional chemical granulation, the blending process does not alter the original chemical composition of the fertilizer; it simply...

 Structure and Working Principle: The rotary drum granulator is the most common large-scale granulation equipment in compound fertilizer and organic fertilizer production lines. Its main body is a slightly inclined rotating cylinder with multiple lifting plates distributed along the circumference of the inner wall. During operation, material enters from the higher end of the...

Equipment Introduction and Applicable Scenarios The windlass compost turner is a core piece of equipment in aerobic composting processes for handling organic materials such as livestock and poultry manure, straw, and sludge. It piles materials into trapezoidal windlasses, relying on the rotating and throwing action of turning wheels or rollers to achieve turning, oxygenation, and displacement of...

A complete organic fertilizer production line needs to transform fermented and decomposed livestock and poultry manure, straw, and other organic waste into commercial organic fertilizer. This involves the coordinated operation of equipment in multiple processes. The following describes the core equipment and functions of each stage according to the production process. Fermentation...

Windlass Fermentation Process: Windlass composting is a process in which organic materials are piled into long, narrow stacks for aerobic fermentation. The stacks are typically 2-4 meters wide at the base, 1-2 meters wide at the top, and 1.2-1.8 meters high, with the length adjustable from tens to hundreds of meters depending on site conditions. The materials are stored in the open air or in a...

NPK Granulation Process Flow A complete NPK granulation process typically includes the following steps: raw material crushing → batching and mixing → granulation → drying → cooling → sieving → coating → packaging. Granulation is the core process, directly determining the particle strength, particle size distribution, and appearance quality of the finished product. After crushing and mixing, the...

Higher Capacity Isn’t Always Better Disc granulators, due to their simple structure, smooth pellet formation, and low investment, have become a popular choice for small and medium-sized organic fertilizer and compound fertilizer plants. However, many users fall into a misconception when purchasing: focusing solely on the “tons per hour” figure and blindly pursuing high-capacity...
