    The  organic fertilizer granulator  plays a key role in the process of treating manure in aquaculture farms, effectively achieving harmless treatment and resource utilization of manure. Below is a detailed introduction to how the organic fertilizer granulator achieves this goal: 1. Reduce environmental pollution Biological deodorization: In the early stage of organic fertilizer granulation, microbial agents are added to accelerate fecal fermentation, which can effectively degrade harmful gases such as ammonia and hydrogen sulfide, reduce odors, and minimize negative impacts on the environment. Solid liquid separation: using solid-liquid separation technology, the liquid part is used for sewage treatment, and the solid part is used as granulation raw material, avoiding the waste of water resources and reducing the possibility of water pollution. 2. Kill pathogens High temperature fermentation: During the composting process, natural heating or a heating system is u...

  The   roller extrusion granulator   is an efficient and critical equipment in the NPK (nitrogen phosphorus potassium) fertilizer production line, mainly used to convert dry powder or slightly moist raw materials into uniform particle form. Its working principle is based on the combination of high-pressure extrusion and shear force, and the specific process is as follows: Workflow Raw material feeding: The raw material (usually NPK fertilizer powder pre mixed and adjusted to the appropriate humidity) is fed between two opposing rotating rollers. High pressure extrusion: These two rollers are driven by strong mechanical pressure. When the raw material reaches the narrowest point between the two rollers, it is subjected to tremendous extrusion force, causing plastic deformation and compression into thin sheets. Fragmentation: Subsequently, due to the discontinuity of its own structure and the effect of internal stress, this thin sheet immediately fractures after leaving th...

  The rotary drum granulator plays a crucial role in the   NPK fertilizer production line , as it completes the granulation process of NPK compound fertilizer through an efficient wet granulation technology. The following are detailed granulation steps and principles: Introduction to NPK Fertilizer NPK fertilizer refers to a compound fertilizer containing three main nutrients: nitrogen (N), phosphorus (P), and potassium (K). It is widely used in crop cultivation to improve soil fertility and crop yield. Working principle of  rotary drum granulator The core of a rotary drum granulator is a large drum shaped container that is tilted and slowly rotated, filled with the material to be granulated inside. This device utilizes a combination of centrifugal force and frictional force to promote the collision and agglomeration of materials during continuous rolling, ultimately forming uniform spherical particles. Specific granulation steps Raw material mixing: Firstly, accurately m...
