Comparison between trough compost turners and crawler compost turners

Written by fertilizer production line on . Leave a comment

In the composting equipment of organic fertilizer production lines, compost turning machine and windrow compost turning machine have their own advantages. Choosing suitable equipment can make production efficiency more efficient.

In terms of application scenarios,compost turning machines are suitable for fixed-site operations and need to be used in conjunction with fermentation tanks. The width of a single tank is usually 3-5 meters and the depth is 1-1.5 meters. They are suitable for large-scale and standardized production bases, especially in the continuous fermentation line of organic fertilizer plants. Windrow compost turning machines are experts in mobile operations. The crawler design enables them to shuttle freely in muddy sites without the need for preset fermentation tanks. The pile height can reach more than 1.5 meters.

Each has its own focus on operating efficiency. The compost turning machine relies on chain transmission to drive the turning and throwing teeth. The hourly processing capacity can reach 50-100 tons. The turning and throwing depth is uniform, the material is highly broken, and oxygen can be fully integrated. The fermentation cycle can be shortened to 7-10 days. Windrow compost turning machines rely on hydraulically driven rotating blades to process 30-80 tons per hour. Although the efficiency per hour is slightly lower, they can adapt to irregular piles and have a small turning radius. Their flexibility in operation on complex sites far exceeds that of trough compost turners.

There are obvious differences in operation and maintenance. Compost turning machines require regular adjustment of chain tension and monthly lubrication of sprocket bearings. Due to fixed operations, the replacement cycle of wear parts is relatively long. Windrow compost turning machines require weekly inspection of track tightness and grease of blade bearings every 100 hours, but their modular design makes replacement of wearing parts more convenient and less time-consuming for daily maintenance.

In terms of energy consumption and cost, compost turning machines have 15%-20% lower energy consumption per unit of processing capacity, but they need to invest in fermentation tank construction in the early stage. Windrow compost turning machines have low initial investment, and mobile operations save site renovation costs, making them suitable for small and medium-sized enterprises.

Both can meet the requirements of harmless compost treatment. The compost turning machine is suitable for large-scale and standardized production, while the windrow compost turning machine is suitable for flexible and changeable operation scenarios. Only by choosing according to your own production needs can you make compost treatment efficient and economical, and help the development of green industry.

An organic fertilizer production line is a systematic set of equipment that converts organic materials such as agricultural waste and livestock manure into high-quality organic fertilizer. Through a series of standardized processes, it achieves the complete transformation from waste to green fertilizer, making it a core piece of equipment for developing ecological agriculture.

Its core function is to deeply process and transform organic raw materials. The raw materials come from a wide range of sources, including pig and chicken manure from farms, straw and rice husks from farmland, as well as edible fungus residue and traditional Chinese medicine residue. These waste materials, which could otherwise cause pollution, are transformed into nutrient-rich organic fertilizer after processing through the production line, addressing environmental concerns and achieving resource recycling.

From a process perspective, an organic fertilizer production line consists of several key links. Raw materials undergo pretreatment, with crushing equipment used to break down bulky raw materials. Mixing equipment then blends the materials in appropriate proportions to ensure an optimal carbon-nitrogen ratio. The fermentation and composting phase then begins. Microorganisms use fermentation tanks or vats to complete high-temperature composting, killing pathogens and insect eggs and degrading harmful substances. The composted materials are processed into granules in a granulator, then dried and cooled to adjust the moisture content. Finally, they are screened and packaged to form the finished product.

The equipment configuration of the production line is customized based on production capacity and raw material characteristics. Small production lines can meet annual production needs of 10,000-30,000 tons and are equipped with simple crushing and turning equipment. Larger production lines integrate intelligent control systems that automatically adjust parameters such as temperature and humidity, reaching annual production capacities of over 100,000 tons and adapting to large-scale production.

In short, organic fertilizer production lines serve as a bridge connecting organic waste and green agriculture. Through scientific processes, they transform “waste” into “treasure.” The resulting organic fertilizer improves soil and enhances crop quality, making them a crucial piece of equipment for promoting sustainable agricultural development.

Written by fertilizer production line on . Leave a comment

In the fertilizer production line, dust pollution not only affects the workshop environment, but also reduces the utilization rate of raw materials. With its targeted design, the cyclone dust collector has become an ideal dust removal partner for the fertilizer production line, protecting the cleanliness of production from raw material crushing to finished product packaging.

It can accurately respond to the dust characteristics of different links. When the chain crusher processes raw materials such as phosphate rock powder and potassium salt, the coarse dust particles generated enter the cyclone dust collector through the tangent line, and are quickly separated under the action of centrifugal force. The purification efficiency is stable at more than 92%, avoiding dust adhesion to the inner wall of the mixing equipment and causing raw material waste.

Facing the wet dust discharged by the half-wet material crusher, the smooth inner wall design of the cyclone dust collector effectively prevents adhesion and blockage. Its conical ash hopper, combined with the timed cleaning device, can discharge wet dust in time to ensure the continuous operation of the equipment. When processing fermented organic fertilizer, it can also reduce the mixing and diffusion of ammonia and dust, improve the air quality in the workshop, and reduce the risk of respiratory diseases among workers.

Compared with traditional bag dust collectors, it is more suitable for the complex working conditions of fertilizer production lines. There is no need to frequently replace filter bags. Facing the corrosive dust commonly seen in fertilizer production, the service life of the stainless steel cylinder can reach more than 5 years, and the maintenance cost is reduced by 40%. The compact structural design can be directly connected to the discharge port of equipment such as crushers and granulators, reducing the pipeline layout and saving 30% of the workshop space.

Today, with increasingly stringent environmental protection requirements, cyclone dust collectors can not only meet the dust emission indicators of fertilizer production, but also improve the utilization rate of raw materials by recycling dust. Choosing it will allow the fertilizer production line to improve its competitiveness in cleanliness and efficiency, and achieve a dual improvement in environmental protection and benefits.

How Cyclone Dust Collectors Work Efficiently

Written by fertilizer production line on . Leave a comment

In the fertilizer production process, from raw material crushing and mixing to granulation and drying, large amounts of dust are generated at every stage. This dust not only contains active ingredients such as nitrogen, phosphorus, and potassium, but may also carry corrosive substances. Cyclone dust collectors, with their targeted design, are an ideal choice for dust control in fertilizer plants.

The cyclone dust collector’s process is precise and efficient, tailored to the characteristics of fertilizer dust. When the dust-laden airflow from the granulator outlet enters the cyclone dust collector, the tangential airflow design creates a strong rotation within the cylinder. Centrifugal force rapidly propels larger particles (such as unformed fertilizer granules) toward the cylinder wall, where they slide down the conical bottom into the dust hopper. These recovered particles can be reused in production, minimizing raw material loss. For smaller fertilizer dust particles, the optimized airflow trajectory prevents them from escaping with the purified airflow. Even the lighter organic fertilizer dust is effectively captured within the stable centrifugal field. Purified air is discharged from the top outlet, preventing dust pollution in the workshop.

Details specifically designed for the fertilizer industry make it even more practical. Considering the potential for fertilizer dust to absorb moisture and clump, the tapered bottom features a wide angle, coupled with a timed dust discharge mechanism to prevent dust accumulation and blockage. The interior of the cylinder is coated with an anti-corrosion coating to protect against acidic and alkaline elements in the fertilizer, extending the life of the equipment. In compound fertilizer production lines, it can simultaneously process mixed dust generated by different raw materials such as urea and monoammonium phosphate, achieving a consistently high purification efficiency of over 90%. In organic fertilizer production lines, it effectively captures light dust from fermented straw and manure, preventing odor and dust contamination.

Selecting the appropriate cyclone dust collector not only creates a clean environment in fertilizer production workshops, but also recycles effective raw materials and reduces costs.

How to make organic fertilizer step by step?

Written by fertilizer production line on . Leave a comment

Organic fertilizer is the “nutritional cornerstone” of green agriculture. The scientific nature of its production process directly determines its effectiveness. The following details the standardized organic fertilizer production process to help you produce high-quality fertilizer.

Step 1: Raw Material Selection and Proportioning

Select organic raw materials such as livestock and poultry manure, straw, and mushroom residue, and sort them to remove impurities. A precise carbon-nitrogen ratio of 25-30:1 is precisely blended, for example, chicken manure and corn straw should be mixed at a ratio of 6:4. A composting agent is added to activate microbial activity.

Step 2: High-Temperature Fermentation

The mixed raw materials are fed into a fermentation tank and stirred 2-3 times daily using a compost turning machine, maintaining a temperature of 55-65°C. This temperature kills pathogens, insect eggs, and accelerates the decomposition of organic matter.

Step 3: Crushing and Screening

The composted material is crushed to an 80-mesh fineness using a chain crusher, then passed through a vibrating screen to remove impurities and ensure uniform particle size. Achieving the required fineness increases the fertilizer’s contact area with the soil by 30%, improving crop absorption efficiency.

 Step 4: Granulation and Drying

A disc granulator is used to granulate the powder into 3-5mm granules. The powder is then dried (60-70°C) to remove excess moisture to less than 15%. A cooling system is also included, increasing granule hardness by 25%, reducing transportation losses.

Step 5: Coating

The dried and cooled granules enter the coating machine, where a specialized coating agent is sprayed onto the granules to form a uniform protective coating. Coating not only reduces moisture absorption and clumping during storage and transportation, but also controls nutrient release, extending the fertilizer’s effective life.

Step 6: Metering and Packaging

The coated product is automatically metered and packaged in 25kg bags. This fully mechanized process reduces manual contact and ensures product cleanliness.

Following this standardized process ensures that organic fertilizers meet national standards while achieving mass production and increased efficiency. Choose professional organic fertilizer production line equipment to enable high-quality organic fertilizers to contribute to sustainable agricultural development.
