Applicable to multiple industries, disc granulators offer a wide range of applications

Disc granulators are not limited to fertilizer production. Their outstanding granulation capabilities make them a valuable tool for a variety of industries, including metallurgy, building materials, and chemicals.

In the metallurgical industry, metal ore powders such as iron ore and manganese ore are processed into granules by disc granulators, facilitating subsequent sintering and smelting processes. This not only improves resource utilization, but also reduces production waste and lowers production costs.

In the building materials industry, disc granulators are used to produce cement raw material granules, ceramsite sand, and other building material granules. The granulation of cement raw materials improves their combustion properties, thereby enhancing cement quality.

In the chemical industry, disc granulators can granulate a variety of chemical raw materials, including catalysts, pigments, and detergents. The resulting chemical products exhibit improved flowability and stability, significantly enhancing product performance and meeting the high standards of chemical production.

Binderless pellet formation process for chicken manure organic fertilizer

Due to its “dry granulation” characteristics, the fertilizer compaction machine eliminates the need for large amounts of binders, maximizing the active organic matter and nutrients in the manure. It is an ideal machine for granulating chicken manure organic fertilizer.

Mature chicken manure must first be crushed and screened to break up any remaining lumps and ensure a uniform particle size (typically 60-80 mesh). This prevents large particles or impurities from affecting the extrusion process. The moisture content must also be strictly controlled, maintaining it between 45% and 50%. Excessive moisture can cause sticking to the rollers during extrusion, while excessive dryness can hinder agglomeration and formation. If the crude fiber content of the chicken manure is too high, a small amount of humus or wood ash can be added to improve the material’s plasticity and enhance pellet strength.

The mixed material is conveyed through a conveyor to the fertilizer compaction machine. The core working components of the machine (a twin-roller or spiral structure) use high pressure to compress the loose material into a continuous sheet or strip intermediate. This intermediate is then processed through crushing and spheronization to form pellets of uniform size. The formed granules are first screened and graded. Unqualified fine powder or large lumps are returned to the crushing stage for reprocessing. Qualified granules enter a cooling facility and are packaged after cooling to room temperature.

Chicken manure organic fertilizer processed by the fertilizer compaction machine has high granular strength and is less prone to moisture absorption and agglomeration. This preserves the natural nutrients of the chicken manure while solving the inconvenience of handling bulk materials. This is a high-quality processing solution that balances nutrient retention and practicality.

The core role of chain crushers in organic fertilizer production

In the organic fertilizer production process, material crushing is a critical pretreatment step, and chain crushers, with their outstanding performance, are the preferred equipment for this purpose. Organic fertilizer raw materials often contain lumps or medium-hard impurities. Inadequate crushing can affect the efficiency of subsequent granulation and mixing processes, as well as the quality of the finished product. It can even lead to problems such as material jamming in the granulator and uneven granulation in the finished fertilizer.

Designed specifically for the characteristics of organic fertilizer, chain crushers can efficiently crush a wide range of organic fertilizer raw materials, including those with a certain degree of moisture and viscosity, addressing the clogging and incomplete crushing issues of traditional crushing equipment. High-speed rotating chains and hammers impact and shear the material, while an adjustable screen allows for easy control of the crushed material’s particle size, meeting the stringent fineness requirements of organic fertilizer production.

Furthermore, the equipment’s sturdy structure, with core components made of wear-resistant steel, can withstand long-term, intensive operation, minimizing production interruptions. This provides a strong guarantee for the stable operation of organic fertilizer production lines, helping companies improve the yield rate of finished fertilizers and production efficiency.

Organic fertilizer production: The green art of transforming waste into treasure

With sustainable agriculture gaining increasing attention, organic fertilizer production has quietly become a crucial bridge between environmental protection and agricultural development. This seemingly simple organic fertilizer production line is actually a sophisticated journey of transforming waste into treasure.

Organic fertilizer originates from a variety of organic waste. Once a major headache, waste materials like livestock and poultry manure, crop straw, and food processing residues have become core raw materials. These materials first undergo pretreatment to remove impurities and undergo pulverization to adjust their physical structure. These raw materials then enter the fermentation stage, the heart of the entire process. Under specific temperature and oxygen conditions, microorganisms actively work, breaking down large organic molecules into smaller molecules that are more easily absorbed by plants, while also killing pathogens and weed seeds.

After fermentation is complete, the material enters the crucial formation stage—granulation. The fertilizer granulator plays a crucial role, using physical pressure to compress the loose powdered fertilizer into granules. This significantly reduces transportation and storage space.

The entire organic fertilizer production line, from raw material pretreatment, fermentation, and granulation to final drying, cooling, screening, and packaging, is closely coordinated. Modern production lines are moving towards greater automation and intelligence, aiming to precisely control every process parameter to ensure a stable and efficient final product.

Its high efficiency is reflected in multiple dimensions. Not only does it rapidly separate materials, its processing capacity can accommodate production scales ranging from small workshops to large factories, but it also boasts strong environmental adaptability—maintaining stable screening efficiency for both dry ore particles and wet organic materials, and exhibiting high tolerance to moisture and viscosity.

Furthermore, the drum screener machine’s core components are constructed of wear-resistant materials, reducing wear over time, extending its service life, and lowering ongoing maintenance costs, making it an ideal choice for material screening across multiple industries.

Rotary drum granulators: A key player in improving fertilizer quality and efficiency

Amidst the growing demand for high-efficiency fertilizers in agriculture, rotary drum granulators, by optimizing the fertilizer production process, have become crucial equipment for driving quality and efficiency improvements.

From a fertilizer quality perspective, rotary drum granulators effectively address the clumping and uneven nutrient distribution issues of traditional fertilizers by precisely controlling the granulation process. During granulation, the raw materials and binder are thoroughly mixed, evenly encapsulating nutrients within the granules, preventing nutrient loss and reduced fertilizer efficiency. Furthermore, the resulting granules possess a moderate hardness, resisting breakage during transportation and storage, reducing fertilizer loss and indirectly improving actual fertilizer utilization.

In terms of production efficiency, rotary drum granulators utilize a continuous operation mode, effectively shortening production cycles. The drum volume can be designed to meet production capacity requirements, ranging from 1-5 cubic meters for small and medium-sized units to over 10 cubic meters for large units, meeting the production needs of fertilizer companies of varying sizes.

In addition, rotary drum granulators support innovation in fertilizer categories. With the increasing popularity of functional fertilizers (such as slow-release and controlled-release fertilizers and trace element fertilizers), this equipment can adapt to the granulation needs of different fertilizer formulations by adjusting parameters such as raw material ratio, temperature, and rotation speed.

For the green development of agriculture, the granular fertilizers produced by the rotary drum granulator facilitate precise fertilization, reducing soil pollution and water eutrophication caused by excessive fertilizer application. This indirectly contributes to sustainable agricultural development and serves as a vital link between fertilizer production and green agriculture.

Double roller press granulator: The core principles and characteristics of dry granulation

Double roller press granulators(fertilizer compaction machines), with their unique dry process, have become a mainstream option in fertilizer granulation production. This double roller press granulator eliminates the need for drying and converts powder into granules through pure physical extrusion.

The core operating mechanism revolves around twin-roll extrusion: an electric motor, via a reducer, drives two synchronously counter-rotating rollers, each with a uniform pattern of hemispherical dimples distributed across its surface. Once the dry powder enters the gap between the rollers, tens of tons of pressure displace the air between the particles, connecting them to form a dense cake. Upon exiting the rollers, the particles naturally break into oblate spherical granules. After subsequent crushing and screening, unqualified powder is automatically mixed back into fresh material for further processing, resulting in a granulation rate typically exceeding 90%.

The double roller press granulator utilizes corrosion-resistant and wear-resistant materials such as stainless steel, ensuring corrosion-resistant contact areas and a long roller life. Its compact design and easy maintenance, along with numerous quick-release features, allow for rapid adaptation to a variety of raw materials, including ammonium sulfate, organic fertilizer, and compound fertilizer.

Advantages and applications of the flat die pelleting machine

The flat die pelleting machine offers significant advantages, with the larger pressure wheel being a key feature. This larger pressure wheel also increases the bearing’s ability to withstand pressure, making the equipment more stable and reliable, and reducing failures caused by pressure. Furthermore, the larger pressure wheel prevents heat generated by extrusion friction from being transmitted to the bearing chamber, ensuring the bearing operates at a low temperature and preventing lubricant leakage, thus extending bearing life. Furthermore, the larger pressure wheel can be repaired two to three times, reducing maintenance costs and increasing project profitability, offering significant advantages over similar equipment.

The flat die pelleting machine is suitable for a wide range of materials. In agriculture, crop straw, such as corn stalks, wheat straw, and rice husks, can be processed into biomass pellet fuel or organic fertilizer. In the domestic sector, some household waste, after sorting and processing, can also be used for pelletizing, achieving resource recycling. In industry, the flat die pelleting machine can easily handle materials such as biofertilizer, coal, carbon black, kaolin, and stone powder, demonstrating its strong material adaptability.

Flat die pelleting machines also play a positive role in environmental protection. On the one hand, they can process large amounts of agricultural and forestry waste, reducing environmental pollution and enabling resource recycling. On the other hand, by converting degradable materials into biodegradable plastic pellets, they provide a new approach to addressing white pollution, promoting the development of environmentally friendly materials and facilitating the achievement of sustainable development goals.

New type two in one organic fertilizer granulator: Efficient integration, simplified production process

The new type two in one organic fertilizer granulator features an integrated “pretreatment + granulation” design, combining two core processes into one. It is the preferred equipment for small and medium-sized organic fertilizer companies to improve efficiency and reduce costs.

The core structure of this new type two in one organic fertilizer granulator consists of two modules: a “mixing and conditioning chamber” and a “granulation and forming chamber,” with the two chambers seamlessly connected. During operation, crushed organic fertilizer raw materials such as straw and fermented manure first enter the upper mixing and conditioning chamber, which is equipped with anti-entanglement stirring paddles. Dual-shaft counter-rotating stirring uniformly mixes the raw materials with a small amount of binder (such as starch residue and humic acid). Furthermore, moisture monitoring and spraying devices installed on the chamber wall ensure real-time adjustment of the raw material moisture to 18%-22%, preventing subsequent mold sticking and loose pellets.

Pretreated raw materials automatically fall into the lower granulation and forming chamber through a built-in material guide channel, eliminating the need for manual transfer. The forming chamber utilizes a flat die granulation core structure, paired with a trapezoidal, non-slip roller and a deep, straight-hole flat die. This not only cuts long fibers in the raw material (preventing them from tangling with the roller) but also achieves low-temperature granulation through vertical extrusion. The formed granules are discharged directly from the outlet, achieving a particle size uniformity exceeding 90%, eliminating the need for secondary screening.

In addition, the new type two in one organic fertilizer granulator is specifically optimized for the characteristics of organic fertilizer raw materials: the mixing chamber agitator is made of a wear-resistant alloy to mitigate frictional losses in fibrous raw materials; the flat die in the granulation chamber can be quickly replaced to accommodate various particle sizes ranging from 2 to 5 mm; and the entire machine is equipped with a variable-frequency motor that adjusts the speed according to the raw material’s moisture and viscosity.

A complete analysis of the application fields of cage crusher

Due to their unique pulverizing mechanism and outstanding performance, cage crushers play an indispensable role in numerous industries and have a wide range of applications.

In the building materials industry, brick and tile factories often use cage grinders to process soft and brittle materials such as shale, industrial slag, and dry clay. After these materials are crushed by cage grinders, a high proportion of fine powder particles is produced, which is crucial for brick forming.

The chemical industry is also an important application for cage crushers. They can grind medium-hard chemical raw materials such as ammonium chloride and ammonium sulfate, ensuring that these raw materials can fully participate in subsequent chemical reactions, thereby improving the production efficiency and quality of chemical products.

In compound fertilizer production, cage crushers are also indispensable for the pulverization of fertilizer raw materials such as urea. This pulverization of raw materials like urea facilitates the even release of nutrients in the fertilizer, enhancing its effectiveness.

In addition, in the production of organic fertilizers, cage crushers can crush organic waste such as sheep manure and straw, so that these wastes can better participate in the fermentation process and be converted into high-quality organic fertilizers, providing a green and environmentally friendly source of fertilizers for agricultural production, helping to improve soil and the healthy growth of crops.
