fertilizer granulator Sep 9, 2025

When selecting an organic fertilizer granules machine, production capacity is one of the most critical considerations for users. The actual output is influenced by a combination of various factors.

1.Raw Material Characteristics

Composition and Formulation: The proportion of fibrous content, organic matter, moisture, oils, and sticky substances in the raw materials directly affects the difficulty and speed of pellet formation.

Moisture Content: Excess moisture can cause clogging, reducing output or even halting production. Too little moisture makes shaping difficult, increases the proportion of returned material, and lowers effective output.

Fineness and Uniformity: Finer and more uniformly mixed raw materials — after crushing and fermentation — flow better and are more easily extruded into pellets.

2.Equipment Model and Process

Machine Type: Flat die granulators are suitable for small to medium outputs and producing small to medium-diameter pellets. Double roller press granulators offer high output and low energy consumption, making them ideal for producing flat spherical organic fertilizer pellets. Disc granulators, on the other hand, allow adjustment of tilt angle and rotation speed to control output and pellet size.

Mold Specifications: For flat die and ring die granulators, smaller apertures and thicker molds increase extrusion resistance, reducing output per unit of time. Conversely, molds with larger apertures yield higher output.

3.Power System

A more powerful motor provides stronger driving force for the extrusion process, enabling it to handle more complex raw materials and higher production loads. This ensures stable and high output.

In summary, the production capacity of an organic fertilizer granules machine is a comprehensive metric influenced by multiple factors, including raw materials, equipment, and power. When aiming for high output, it’s important to consider the specific raw material conditions and select the appropriate machine type.

Requirements for raw materials in double roller press granulator: How to choose suitable materials?

fertilizer granulator Aug 26, 2025

Double roller press granulators are efficient and energy-saving equipment widely used in producing granular fertilizers like organic fertilizer, compound fertilizer, and bio-fertilizer. However, not all raw materials are directly suitable for extrusion granulation. The physical and chemical properties of the material directly affect the granulation results.

Physical Property Requirements

1.Appropriate Particle Size

Raw materials must be crushed, generally to 80-200 mesh (0.074-0.2mm). Particles that are too coarse make forming difficult, while particles too fine can affect flowability and cause the material to stick to the rollers.

2.Moderate Moisture Content

Excessive moisture (>15%) causes material to stick to the rollers and affects demolding. Insufficient moisture (<8%) makes forming difficult, and the granules become brittle. The optimal moisture range is usually 8%-12%, though this may vary based on material characteristics.

3.Good Plasticity

Materials need some stickiness and plasticity (like humic acid, composted manure, bentonite) to help improve granule formation rate and hardness.

Chemical Property Requirements

1.Moderate Organic Matter Content

For organic fertilizer materials (like compost, humic acid), an organic matter content of 30%-70% is recommended. Too high can lead to loose granules; too low affects fertilizer efficiency.

2.No Corrosive Components

Strong acids, strong alkalis, or high-salt substances should be avoided in the raw materials to prevent equipment corrosion or harm to crops.

3.No Hard Impurities

Hard objects like stones or metal fragments can damage the double roller press granulator die. Screening or magnetic separation is needed before granulation.

Double roller press granulators have strict requirements for raw material particle size, moisture, and binding properties. Selecting suitable materials and optimizing process parameters are essential for producing high-strength, qualified granular fertilizer.

As an important organic fertilizer production equipment, the double roller press granulator can always maintain efficient operation, extend its service life, and escort production. Mastering scientific maintenance methods can not only reduce the hidden dangers of failure, but also enable the equipment to output high-quality particles stably for a long time.

Daily maintenance needs to form a standardized process. Before starting the machine, in addition to checking the connection and fasteners of the components, it is necessary to focus on whether the feed port is unobstructed, remove possible foreign matter, and avoid material jamming and damage to the equipment after starting. During operation, in addition to paying attention to the rotation and sound of the rollers, it is also necessary to observe the temperature of the motor. If overheating occurs, the machine should be shut down to cool down to prevent the motor from burning. The cleaning work after shutdown should be thorough. A special brush can be used to clean the residual material in the roller texture, and compressed air can be used to blow the equipment gap to prevent the material from corroding the components after moisture and agglomeration.

Maintenance of key components must be accurate and in place. The parallelism of the rollers needs to be checked every time they run for a period of time. If there is an offset, it should be calibrated in time to ensure uniform extrusion force; when the surface is worn to a certain extent, it can be polished and repaired to extend the service life. Bearing lubrication requires the use of lubricating oil of suitable types, which should be refilled at least once a month. Before refilling, clean the impurities in the oil filling port to prevent contamination of the lubrication system. The chain of the transmission system should be regularly smeared with chain oil, and the gears should be checked for meshing. If abnormal noise or jamming is found, timely adjustments should be made to avoid affecting the granulation efficiency due to poor power transmission.

Well-maintained equipment can reduce downtime, maintain stable granulation efficiency and granule quality, and reduce long-term use costs. Choose a double roller press granulator and cooperate with scientific maintenance to make your organic fertilizer production line continue to be efficient and your profits more guaranteed.

The unique working principle of the double roller press granulator

fertilizer granulator Aug 16, 2025

The reason why the double roller press granulator can occupy an important position in the organic fertilizer granulation equipment is inseparable from its unique working principle, which also allows it to show many advantages.  Its working process is clear and straightforward. First, the pre-treated dry powder raw material is conveyed between two relatively rotating rollers. The surface of this pair of rollers is usually provided with specific lines or grooves. Under the action of strong extrusion force, the raw material is tightly squeezed to form continuous flakes. These flakes then enter the crushing device and are crushed into particles of different sizes. Next, the particles will go through the screening stage, and the fine powder or large particles that do not meet the requirements will be separated and sent back to the granulation system, while the qualified particles will become the final product.

This working principle brings significant advantages. There is no need to add a lot of water, and the subsequent drying step is omitted, which not only saves energy, but also maintains the original nutritional content of the raw materials. The whole process is coherent and efficient, from the entry of raw materials to the output of qualified particles, which can be completed in one go and quickly meet production needs. At the same time, due to the physical extrusion granulation, it has strong adaptability to raw materials, and a variety of organic raw materials can be made into granules in this way.

The double roller press granulator has become an efficient and practical granulation choice in the organic fertilizer production line due to its scientific working principle, helping producers improve efficiency and ensure quality.
