  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...

  The working principle of   organic fertilizer granulation equipment   is mainly based on physical and chemical methods to process fermented organic materials into regular granules. This process involves multiple steps and technologies. Below are several common organic fertilizer granulation technologies and their principles in detail: 1. Roller granulation Principle: Drum granulation is the most common method, mainly relying on the rotational force of the drum to make the material roll inside the drum, gradually forming spherical particles. In this process, the material helps shape the particles through its own adhesion and external humidification (if necessary). As the drum rotates, smaller particles will be compressed around larger particles, gradually increasing until reaching the desired size. 2. Disc granulation Principle: The  disc granulator  rotates through an inclined circular disc surface, and the material rolls on it. With the help of centrifugal fo...

  The cow manure   organic fertilizer production line   is an important way to convert cow manure into high-quality organic fertilizer, which not only recovers agricultural by-products but also improves soil quality and promotes crop growth. Below is a detailed introduction to the processing flow and advantages of cow manure organic fertilizer: Processing flow Raw material collection and pretreatment Collect fresh cow manure and transport it to the pre-treatment area using tools such as forklifts. Use a screening machine to remove solid debris such as stones, metal sheets, etc. Add auxiliary materials as needed, such as straw, sawdust, husks, etc., to adjust the C/N ratio and moisture, which is beneficial for microbial activity. Fermentation treatment Put the pre treated cow manure into a fermentation tank or tank, add an appropriate amount of biological fermentation agent, and start aerobic fermentation. Regularly use an organic fertilizer turning machine to ensure a ful...

  The pig manure organic fertilizer production process is divided into pre-fermentation and post-granulation links. The fermentation link only needs a fermentation turning machine or fermentation turning and throwing machine equipment and a lot of equipment is used in the granulation link, generally it is necessary to purchase a complete set of pelletizing production line equipment. This article and you will learn more about the pelletizing equipment process technology of the pig manure organic fertilizer production line. Pig manure organic fertilizer granulation production line technology: 1. Organic fertilizer raw materials accumulation and fermentation equipment-  compost turning machine . It adopts a new design of one machine with multiple tanks to realize cyclic feeding and discharging, and cyclic fermentation. 2. New type of dry and wet material crusher-vertical crusher and horizontal crusher. 3. Fully automatic multi-warehouse batching machine-According to the customer'...

  The equipment composition of the cow manure processing   organic fertilizer production line   covers the entire process from raw material processing to final product packaging, mainly including the following key components: 1. Preprocessing equipment Solid liquid separator: used to separate the liquid and solid in cow manure and extract relatively dry solid cow manure. Crusher: Preliminary crushing of solid cow manure to make it easier for further fermentation treatment. 2. Fermentation equipment Fermentation tank/fermentation chamber: Provides a temperature controlled and ventilated environment to promote microbial activity and accelerate the biodegradation of cow manure. Organic fertilizer turning machine : Regularly turning over the cow manure pile to ensure air circulation during the fermentation process, which helps to achieve uniform fermentation. 3. Drying equipment Drum dryer: removes most of the moisture from fermented cow manure, facilitating subsequent granul...
