Drum fertilizer coolers are continuously operating industrial equipment. Inadequate routine maintenance can easily lead to frequent failures, impacting production schedules and shortening equipment lifespan.
First, regularly inspect the transmission system. The bearings and gears in the transmission are highly consumable and should be inspected weekly. Observe the bearings for unusual noises or heat buildup. Excessive temperatures may indicate insufficient lubrication or bearing wear, requiring timely lubrication or bearing replacement.
Second, ensure the cooling system is clean. Prolonged cleaning of the cooling jacket can lead to accumulation of scale and impurities, impairing heat transfer and reducing cooling effectiveness. It is recommended to clean the jacket every three months. If using cold water cooling, circulate a citric acid solution to remove scale. If using cold air cooling, clean the air inlet filter monthly to prevent dust from clogging the filter and reducing air flow.
Third, inspect the sealing components for leaks. Seals at the feed, discharge, and exhaust ports (such as rubber rings and asbestos gaskets) are prone to leakage due to wear and aging. They should be inspected monthly. If dust or cooling medium leakage is detected, the seals should be replaced promptly.
Fourth, regularly clean the drum fertilizer cooler interior. Even with suitable materials, a small amount of material may remain on the drum interior after long-term operation. If not cleaned, this material will gradually accumulate and affect the uniformity of material turnover. It is recommended to use a special scraper to clean any remaining material from the drum fertilizer cooler interior after weekly shutdown.
With the large-scale development of organic fertilizer production, intelligent control has gradually become a core means of improving organic fertilizer production line stability. Compared to traditional manual monitoring, intelligent systems can precisely control key parameters, reduce operational errors, and ensure consistent finished product quality.
Intelligent control is primarily applied in three key areas: First, fermentation process monitoring. By deploying temperature, humidity, and oxygen concentration sensors, the system collects real-time data from the fermentation chamber. When parameters deviate from the appropriate range, the system automatically triggers an alarm and adjusts the turning frequency and ventilation volume to prevent under- or over-roasting of the material. Second, granulation process control. Based on changes in material moisture content, the system automatically adjusts the fertilizer granulator machine speed and binder dosage to minimize problems such as granule clumping and breakage. Third, production data management. The system automatically records operational data from each stage, creating a production ledger that facilitates process traceability and allows for optimization of process parameters through data review.
This intelligent transformation of organic fertilizer production lines does not require replacing core equipment; it is often achieved through the addition of sensors and upgraded control systems. This reduces labor costs and improves the yield of finished products, making it suitable for small and medium-sized production enterprises to implement gradually.

Under the trend of green agricultural development, the bio-organic fertilizer production line, with its unique technological advantages, has become a key piece of equipment driving the transformation and upgrading of the fertilizer industry.
The production line’s technical core lies in three dimensions: First, a precise batching system. Automated equipment precisely controls the ratio of raw materials and inoculants, ensuring stable microbial activity and balanced nutrient distribution. Second, intelligent fermentation control. Sensors monitor the compost temperature, humidity, and oxygen content in real time, automatically adjusting the turning frequency and ventilation rate of the compost turning machine to shorten the fermentation cycle and improve compost maturity. Third, low-temperature post-processing technology utilizes a 60-80°C drying process to prevent high temperatures from damaging microbial activity and organic matter structure, thereby maximizing the nutrient value of the fertilizer.
From an industry perspective, the bio-organic fertilizer production line offers multiple benefits: For the livestock industry, it effectively disposes of waste such as livestock and poultry manure, addressing environmental concerns. For agricultural production, the bio-organic fertilizer produced improves soil compaction and fertility, reducing reliance on chemical fertilizers and promoting improved crop quality and efficiency. For the ecological environment, the fully closed-loop production process reduces pollutant emissions and promotes the recycling of agricultural waste.
The bio-organic fertilizer production line utilizes organic waste such as livestock and poultry manure, straw, and mushroom residue as raw materials. Through microbial fermentation technology, it recycles resources and produces fertilizer rich in active bacteria and organic matter. Bio-organic fertilizer production lines serve as a vital link between the livestock and poultry industry, the agricultural industry, and the environmental protection industry.
Raw material pretreatment is a fundamental step. It requires crushing and screening the organic waste to remove impurities and ensure a uniform particle size (approximately 80 mesh). Auxiliary materials are then added to adjust the carbon-nitrogen ratio (25-30:1) and humidity (55%-65%) to create a suitable environment for microbial growth. This phase then enters the inoculation and fermentation stage, where specialized microbial agents are added to the mixture. A compost turning machine regularly turns the compost to provide oxygen, maintaining a temperature of 55-65°C. Composting continues for 20-30 days, effectively killing pathogens and insect eggs and breaking down large organic molecules.
The fermented material undergoes post-processing to optimize quality. First, it undergoes low-temperature drying to reduce moisture to below 12% to prevent mold and mildew during storage. It then undergoes crushing, screening, and grading, with unqualified particles returned to the pre-processing stage for recycling. Finally, functional microbial agents can be optionally added to the mix to enhance the bioactivity of the fertilizer, depending on crop needs. The resulting pellets are uniform and rich in humic acid, amino acids, and a variety of beneficial bacteria, providing nutrients for crops while also improving the soil microbial ecosystem.
In the field of material pulverization, cage crushers, with their unique performance advantages, have become an ideal choice for many manufacturers and occupy a key position among various types of pulverizers.
In terms of compatibility, cage crushers are excellent for processing low- to medium-hardness materials, particularly those with a Mohs hardness of 1.0-2.0. Materials with a hardness exceeding 3 are less suitable due to excessive wear on the cage.
In terms of pulverization performance, cage crushers offer excellent fineness control. By precisely controlling the screen aperture, fineness can be adjusted from 0.2 to 5.0 mm. The high precision of the screen aperture guarantees a 90% particle size deviation of ≤0.2 mm.
In terms of uniformity, the unique synergistic effect of impact and grinding produces a narrow particle size distribution. For example, when crushing corn, 80% of the particles are concentrated between 0.8 and 1.2 mm, resulting in minimal over-fine grinding. Material loss is low, sealing performance is excellent, and the dust rate is only 3% to 5%.
Energy consumption and maintenance are also important indicators of crusher performance. The specific energy consumption of a cage crusher is moderate. For example, when crushing corn, the energy consumption ranges from 8.5 to 15.6 kW h/t, but energy consumption increases with finer grain size. The lifespan of its wearing parts is relatively long.
Regarding maintenance, while regular cleaning of the screen and cage residue is required, and cage replacement requires complete machine disassembly, overall, the maintenance effort and cost are relatively moderate.
With its comprehensive advantages in material compatibility, crushing efficiency, energy consumption, and maintenance, cage crushers demonstrate strong competitiveness in applications requiring medium-to-fine crushing of low- to medium-hardness materials, with high requirements for crushing accuracy and particle shape.
As a compound fertilizer with a synergistic combination of nitrogen, phosphorus, and potassium, NPK fertilizer production requires standardized production lines for large-scale production. Through the coordinated operation of multiple links, NPK fertilizer production lines efficiently transform raw materials into finished products, providing agricultural production with high-quality fertilizers with balanced nutrients.
The core processes of an NPK fertilizer production line revolve around “precise proportioning, uniform mixing, and stable forming.” First, in the raw material pretreatment stage, nitrogen, phosphorus, and potassium fertilizers (such as urea, monoammonium phosphate) and fillers are crushed and screened to ensure uniform particle size and prevent large particles from affecting subsequent mixing and granulation.
Next, in the mixing stage, an automated batching system precisely measures each raw material according to a preset formula. The raw materials are then fed into a mixing device for thorough mixing. The uniformity of the mixing directly determines the nutrient consistency of the fertilizer. The granulation process is the core of the production line. The raw material mixture is conveyed through a conveyor into the NPK fertilizer granulator machine, where it is tumbled or extruded with the aid of a binder to form granules. The granules’ shape and strength must be adapted to subsequent storage and transportation requirements.
After granulation, the wet granules enter a drying and cooling system, where they are dried with hot air to reduce moisture. They are then cooled to room temperature by a cooling device to prevent the granules from clumping and deteriorating. Finally, after screening and grading, qualified granules are packaged, while unqualified granules are crushed and returned to the granulator for reuse, thus achieving resource recycling.
In thefertilizer production line, the compost turner serves as the core equipment in the raw material fermentation process. Raw materials that have undergone pretreatment (crushing, mixing, and carbon-nitrogen ratio adjustment) are transported to the fermentation area and stacked into windrows for turning and fermentation by the crawler-type compost turner. The composted materials are then conveyed to subsequent processes (crushing, granulation, drying, etc.) through conveyors, forming a continuous “pretreatment-fermentation-deep processing” workflow. This efficient turning operation provides high-quality raw material assurance for subsequent processing stages.
Large-scale Continuous Fermentation
For large-scale fertilizer production lines (with an annual output of over 50,000 tons), the compost turner can simultaneously serve multiple groups of windrows, achieving continuous production through a “multi-zone rotation” model: Zone one for new material loading, zone two for high-temperature fermentation, and zone three for cooling and maturation. The equipment operates on a fixed cycle with an average daily processing capacity of 800-1,500 tons, meeting the needs of large-scale production. This operation mode significantly improves site utilization and equipment efficiency.
Production Rhythm Matching
The travel speed and turning frequency of the compost turner can be steplessly adjusted through the electronic control system, allowing flexible adjustment of the fermentation schedule according to the raw material supply rate and backend processing capacity. For example, when granulator capacity increases, the turning frequency can be correspondingly increased to accelerate material maturation, ensuring the fermentation process remains synchronized with the overall production line rhythm. This flexible adjustment capability ensures stable operation of the production line.
Diversified Production Models
The compost turner can independently complete open-air windrow fermentation operations or combine with fermentation silos, conveyors and other equipment to form semi-closed production lines. For scenarios requiring mobile operations (such as livestock farms and temporary waste disposal sites), the compost turner can be flexibly moved with raw material production sites without fixed installation, greatly enhancing the production line’s mobility. This flexibility enables it to adapt to different production environments and operational requirements.
Process Optimization Value
In contemporary fertilizer manufacturing, the strategic deployment of specialized equipment forms the backbone of efficient production systems. The compost fertilizer machine, particularly the large wheel compost turner and chain compost turner, plays a pivotal role in initial processing stages, significantly enhancing fermentation efficiency while ensuring consistent product quality through precise aeration and temperature control. These robust machines serve as crucial connectors between preliminary and subsequent stages within the comprehensive organic fertilizer production line.
The transition from composting to granulation represents a critical phase in the equipments required for biofertilizer production. Advanced granulation technologies, including the versatile rotary granulator for organic materials and the precision-oriented disc granulation production line for uniform particle formation, demonstrate the sophistication of modern fertilizer production machine systems. The drum granulation process further expands this capability, particularly within npk fertilizer production line configurations, while the double roller press granulator offers alternative compaction-based granulation methods.
Complete production ecosystems, whether configured for bio organic fertilizer production line operations or dedicated npk production line setups, integrate these components into seamless manufacturing processes. The large wheel compost turning machine ensures optimal composting conditions, while downstream equipment like the drum organic fertilizer dryer maintains product integrity through controlled moisture reduction. Each fertilizer granulator unit contributes to creating specialized formulations, demonstrating how interconnected technologies support the standardized, large-scale advancement of sustainable fertilizer production worldwide.
