What factors determine the output of an organic fertilizer granules machine?

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.

Essential maintenance for flat die granulators in organic fertilizer plants

In organic fertilizer production lines, the flat die granulator is the core shaping equipment. Its operating condition directly affects pellet quality, production efficiency, and machine lifespan. Proper maintenance reduces downtime, cuts energy use, and extends the equipment’s life.

1.Daily Cleaning and Lubrication
Clean residue after each shift: Use proper tools to remove built-up material from the die plate and roller surfaces to prevent corrosion and clogging.
Check lubrication regularly: Add high-temperature grease to bearings every 8 hours. Lubricate drive gears weekly.
2.Wear Part Monitoring and Replacement
Check die plate wear: Measure die hole diameters weekly. Replace the plate immediately when wear exceeds 10% of the standard size.
Maintain rollers: Inspect roller grooves for every 500 tons of fertilizer produced. Repair or replace rollers if groove wear reaches 3mm deep.
Clean screens regularly: Clear screen blockages every shift. Check screens for damage monthly.

3.Electrical System Preventive Care
Dust control cabinets: Clean dust from electrical components and check terminal tightness quarterly.
Calibrate sensors: Professionally calibrate level sensors and temperature sensors every six months.
4.Seasonal Deep Maintenance
Before peak season: Fully inspect the drive system. Replace worn seals.
During shutdowns: Disassemble and clean the entire machine. Apply anti-rust treatment to rusty parts.
Long-term storage: Drain the lubrication system. Coat key parts with anti-rust oil. Protect the motor from moisture.

Establishing this maintenance system keeps flat die granulators running at their best. Following these steps lowers production cost per ton and ensures consistent product quality.

Where are flat die granulators used?

With its unique extrusion molding principle, flat die granulators have demonstrated strong application potential in a variety of fields, making them an ideal choice for small- and medium-scale production. Their core structure consists of a flat die and a pressure wheel. The rotation of the pressure wheel squeezes the material through the die holes, forming cylindrical pellets. This simple and direct operation gives them wide applicability.

Flat die granulators perform exceptionally well in fertilizer production lines. When processing bio-organic fertilizers, they can directly pelletize wet fermented materials without the need for additional drying pretreatment, preserving the activity of beneficial bacteria while streamlining the production process. For nitrogen, phosphorus, and potassium compound fertilizers, their powerful extrusion capabilities can compress mixed powders into high-strength pellets, effectively eliminating the clumping problem associated with traditional pelleting. They are particularly suitable for producing high-concentration specialty fertilizers.

Flat die granulators are also essential for the feed processing industry. For poultry and livestock feed, they can compress raw materials such as straw powder and soybean meal into pellets, reducing feed losses during transportation. High-temperature extrusion kills parasite eggs in the raw materials, enhancing feed safety. In aquatic feed production, pellet density can be controlled by adjusting die hole size to meet the feeding needs of fish in different water layers.

In the environmental protection field, flat die granulators are a valuable aid in solid waste treatment. They can compress municipal sludge, agricultural and forestry waste, and other materials into fuel pellets, realizing waste resource utilization. These pellets have high combustion efficiency and low pollutant emissions, providing new ideas for the development of new energy sources.

The flat die granulator‘s advantages also lie in its flexible operation. By simply replacing dies with different apertures, a wide range of pellet specifications can be produced to meet the needs of diverse industries. The equipment also occupies a small footprint and is easy to install and maintain, making it suitable for small and medium-sized enterprises. As the concept of green production becomes increasingly popular, the flat die pelletizer, with its high efficiency, energy conservation, and versatility, continues to provide a reliable solution for material forming in various fields.
