With simple structure and low operating costs, it is widely used for gas purification in various industrial processes including cement, chemical, metallurgical, power, and food processing industries, effectively removing dust and particulate matter from flue gas.

Equipment Structure and Composition

Core Components:

• Inlet Pipe:Guides dusty gas into the collector, designed tangentially or spirally to promote airflow rotation
• Cyclone Body:Main part of the equipment, cylindrical design with smooth inner walls for generating and maintaining rotating airflow
• Cone Section:Located below the cyclone body, conical structure helps further separate and collect particulate matter
• Exhaust Pipe:Located at the top of the cyclone body for discharging purified gas
• Ash Hopper:Located at the bottom of the cone for collecting and storing separated particles
• Ash Discharge Device:Star-shaped discharge valves, screw conveyors, etc., for regular removal of particulate matter from the ash hopper

Working Principle

Dusty gas enters the cyclone dust collector through the inlet pipe and enters the cyclone cylinder tangentially or spirally, forming a high-speed rotating airflow. Under centrifugal force, heavier particles are pushed toward the cylinder wall and then fall along the wall into the ash hopper, achieving separation from the airflow. Purified gas is discharged through the central exhaust pipe. The rotating airflow continuously decelerates in the cyclone body and cone, further improving separation efficiency and ultimately achieving dust removal goals.

Multi-dimensional adaptation requirements of NPK fertilizer production lines for granulators

fertilizer granulator Nov 3, 2025

As NPK fertilizers transition towards “precise formulation and scenario-based adaptation,” granulators, as the core forming equipment in NPK fertilizer production lines, must adapt to customized production requirements involving multiple formulations, multiple forms, and high uniformity. Their performance directly determines the nutrient stability and application suitability of NPK fertilizers.

1.Formulation Compatibility

NPK fertilizer formulations are flexible and varied, not only with significant differences in nitrogen, phosphorus, and potassium ratios but also often including trace elements and slow-release agents. The specific gravity and viscosity of raw materials vary greatly. Fertilizer granulators must have a wide range of raw material adaptability capabilities, handling both free-flowing raw materials such as urea and potassium chloride, and compatible with composite raw materials containing viscous components such as humic acid and amino acids, avoiding granule agglomeration and uneven forming rates due to differences in raw material characteristics.

2.Precise and Flexible Parameter Adjustability

Different crops and different fertilization scenarios have different requirements for NPK granule size, hardness, and dissolution rate. Fertilizer granulators need to support precise control of granule parameters, allowing for rapid switching of granule diameter (1-5 mm) and hardness grade by adjusting parameters such as die size, extrusion pressure, and rotation speed.

3.Low Loss and Environmental Friendliness

NPK raw materials are mostly chemical or compound materials. During granulation, it is necessary to avoid high temperatures or excessive extrusion that could lead to nutrient loss. The granulator must employ a low-temperature molding process to maximize the preservation of raw material activity. Simultaneously, a closed design must reduce dust emission, minimizing raw material waste and environmental impact.

Flat die pelleting machine: Protecting the activity of microbial agents in low-temperature granulation

fertilizer granulator Nov 3, 2025

The core challenge in biofertilizer production lies in ensuring that the granulation process does not destroy the activity of the microbial agent. Most functional bacteria (such as Bacillus subtilis and Trichoderma harzianum) are significantly inactivated at temperatures above 45°C. The flat die pelleting machine, with its low-temperature granulation capabilities, is a suitable choice for biofertilizer production. Its core advantage lies in its low-friction, no-additional-heat granulation process.

The flat die pelleting machine utilizes a vertical extrusion process, with the rollers and the die in contact with each other over a surface area rather than at points. This results in more uniform force per unit area, less frictional heat generation, and a temperature within the granulation chamber typically maintained at 35-40°C, well below the inactivation threshold of the microbial agent.

Furthermore, the machine does not rely on high-temperature conditioning or hot air conditioning; instead, it achieves granulation solely through the viscosity of the raw material and moderate extrusion, eliminating the need for additional heat input.

Furthermore, the flat die granulator’s speed is adjustable (typically 30-50 rpm). For biofertilizer raw materials with high microbial content, the speed can be reduced to below 30 rpm to further reduce frictional heat generation and ensure a microbial survival rate above 85%.

In practical applications, it is even more effective when used with a “room-temperature binder.” This eliminates the need for heating and dissolving the pellets, while also improving the pelletizing efficiency and complementing the flat die pelleting machine‘s low-temperature characteristics. This ensures the biofertilizer’s core function (microbial activity) while producing uniform pellets, meeting the dual requirements of “functionality” and “commerciality.”

Operational adjustment tips for ring die granulators in low-temperature environments

fertilizer granulator Nov 3, 2025

During winter in northern China or in low-temperature workshops (temperatures below 5°C), ring die granulators are prone to low pelletizing efficiency and poor pellet formation due to decreased raw material viscosity and insufficient lubrication of equipment components. Targeted adjustments are required to ensure proper operation.

During raw material processing, an electric heater can be added to the conditioner to preheat the raw materials to 15-20°C. This increases raw material molecular activity and viscosity, preventing low-temperature conditions that can lead to agglomeration and difficulty in extrusion.

Also, the steam saturation can be appropriately increased (from 80% to over 90%) to utilize steam heat to assist in heating the raw materials and prevent moisture from freezing at low temperatures, which can affect pelletizing. During raw material storage, insulation should be installed in the silo to prevent the raw materials from cooling too low during storage and avoid wasted energy from secondary heating.

Before operating the ring die granulator, preheat the ring die and rollers for 30 minutes. This can be done by running the machine at no load to allow frictional heating, or by wrapping the outer ring die with an electric heat tracer. The temperature should be set between 25-30°C to prevent the raw material from solidifying and clogging the die bore due to low temperatures. The lubricant should also be replaced with a low-temperature-specific lubricant (viscosity grade 46#) to prevent freezing and potentially blocking transmission components. The lubricant fluidity should be checked every two hours to ensure proper lubrication.

These adjustments can effectively mitigate the effects of low temperatures on the ring die granulator, ensuring a pellet formation rate above 95% and preventing material waste due to low temperatures.

Organic fertilizer production line processing chicken manure: A comprehensive analysis of key considerations

fertilizer granulator Nov 3, 2025

Chicken manure, rich in nutrients and widely available, is a high-quality raw material for organic fertilizer production. However, due to its high moisture content, susceptibility to fermentation and spoilage, and the presence of impurities, key processes must be carefully controlled to ensure product quality and smooth production.

Pretreatment is fundamental. Fresh chicken manure typically has a moisture content of 70%-80%. It needs to be reduced to 55%-60% using organic fertilizer production equipment to prevent anaerobic putrefaction during fermentation. Simultaneously, impurities such as stones, plastics, and feathers must be removed manually or mechanically to prevent damage to subsequent equipment. If the chicken manure is severely clumped, it needs to be crushed to ensure uniform particle size, laying the foundation for fermentation.

The fermentation stage is crucial. Chicken manure has a high nitrogen content and needs to be mixed with straw, sawdust, and other carbon source materials in a specific ratio to adjust the carbon-to-nitrogen ratio to 25-30:1, promoting microbial activity. During fermentation, the compost pile needs to be turned regularly using a compost turning machine to ensure aeration and maintain a high temperature of 55-65℃ for 7-15 days to achieve sterilization, insect control, and decomposition.

Subsequent processing must be standardized. The decomposed chicken manure needs to be crushed and screened again to ensure there are no large pieces of uncomposted material, with a particle size controlled within 2 mm for easy granulation. During granulation, the material moisture content must be controlled at 20%-30% to avoid clogging the die holes; the drying temperature should not exceed 80℃ to prevent damage to organic matter and beneficial microorganisms. Simultaneously, the entire organic fertilizer production line must be properly sealed and deodorized to reduce odor diffusion and meet environmental protection requirements.
