Introduction
Agriculture and industry today rely heavily on efficiency, sustainability, and advanced technology. As the demand for high-quality soil conditioners and fertilizers continues to rise, granulation equipment has become essential for meeting production needs. Two machines stand out in this field: the bentonite granules making machine and the npk compound fertilizer granulation production line.
Both systems serve different purposes, yet they share a common goal—transforming raw materials into durable, uniform, and easy-to-handle granules. Bentonite clay is processed into granules that enhance soil quality and industrial applications, while NPK fertilizers deliver balanced nutrition to crops for higher yields. Together, these technologies support sustainable agriculture, industrial growth, and environmental safety.
This article provides a detailed look into both systems, their working principles, advantages, applications, cost factors, and how they shape modern production processes.
Section 1: Bentonite Granules Making Machine
What is Bentonite?
Bentonite is a naturally occurring clay derived from volcanic ash. Its primary mineral component, montmorillonite, has unique swelling and binding properties. Depending on its composition, bentonite is categorized into two types:
- Sodium Bentonite – Known for high swelling capacity, water absorption, and sealing ability.
- Calcium Bentonite – Offers stronger structural stability but lower swelling potential.
These properties make bentonite highly versatile, with applications in agriculture, drilling, construction, animal feed, and environmental protection.
Why Granulate Bentonite?
While bentonite powder is widely used, it comes with limitations. Fine powders are dusty, difficult to handle, and often lose efficiency during application. By using a bentonite granules making machine, manufacturers can:
- Improve handling and storage.
- Produce uniform granules with consistent size.
- Enhance application in soil or industrial processes.
- Reduce material loss and environmental dust pollution.
Working Principle of the Bentonite Granules Making Machine
The bentonite granules making machine—often a double roller extrusion granulator—uses mechanical force to compress bentonite powder into solid granules.
Process steps include:
- Material Preparation – Bentonite is crushed and dried if moisture exceeds 12%. A mixer may be used to add water or binders for better granulation.
- Feeding System – The prepared material enters the granulator through a controlled feeder.
- Extrusion – Two counter-rotating rollers press the bentonite into a compacted sheet.
- Granule Formation – The sheet passes through a shaping system, breaking into uniform granules (3–10 mm).
- Screening & Packaging – Finished granules are separated from fines, packaged, and stored for use.
Advantages of the Bentonite Granules Making Machine
- Energy Efficient – Consumes less power compared to drum or disc granulators.
- Low Investment – Requires minimal setup cost.
- Eco-Friendly – Operates without drying or heating, reducing emissions.
- Durable Granules – Produces strong, round, and uniform particles.
- Multi-Functional – Capable of handling other materials such as gypsum, dolomite, and organic minerals.
Applications of Bentonite Granules
- Agriculture – Improves soil fertility and moisture retention.
- Drilling Industry – Enhances drilling mud properties.
- Foundry – Acts as a binding agent for molding sands.
- Construction – Used in waterproofing and sealing works.
- Animal Care – Serves as cat litter due to its absorption capacity.
By installing a bentonite granules making machine, industries benefit from stable production and versatile applications.
Section 2: NPK Compound Fertilizer Granulation Production Line
What is NPK Fertilizer?
NPK fertilizer is a compound fertilizer made of three essential nutrients:
- N (Nitrogen) – Boosts vegetative growth and chlorophyll formation.
- P (Phosphorus) – Supports root development and flowering.
- K (Potassium) – Improves disease resistance, fruit quality, and overall plant strength.
Balanced NPK fertilizers are critical for modern agriculture, providing tailored nutrition for different crops and soils.
Why Use an NPK Compound Fertilizer Granulation Production Line?
Powdered fertilizers are inconsistent in nutrient distribution and difficult to apply evenly. A npk compound fertilizer granulation production line converts these powders into uniform granules that:
- Ensure even nutrient distribution in fields.
- Enhance storage stability and reduce caking.
- Improve ease of handling and application.
- Allow customization of nutrient ratios.
Working Process of the NPK Compound Fertilizer Granulation Production Line
A standard 10 T/H npk compound fertilizer granulation production line involves several steps and machines working together:
- Batching and Mixing – Raw materials such as urea, DAP, ammonium sulfate, potassium chloride, and fillers are weighed and blended.
- Crushing – Large lumps are broken down into fine powder for uniform granulation.
- Granulation – A double roller extrusion granulator compresses the mix into granules.
- Screening – Oversized and undersized particles are separated, and qualified granules move forward.
- Drying and Cooling (Optional) – Moisture is reduced for long-term storage.
- Packaging – Finished fertilizer is packed into bags, often with automatic weighing and sealing machines.
Technical Specifications
A 10 T/H npk compound fertilizer granulation production line usually consists of:
- Loader-type feeder
- Cage crusher
- Disc feeder
- Double roller extrusion granulators (multiple units for efficiency)
- Rotary screening machine
- Automatic packing scale
Production Capacity: 8–10 tons per hour
Annual Output: 30,000+ tons

Applications of NPK Fertilizer Granules
- Field Crops – Wheat, rice, corn, and barley.
- Cash Crops – Fruits, vegetables, and flowers.
- Horticulture – Turf grass, ornamental plants, and greenhouse cultivation.
- Commercial Farming – Large-scale crop production for export.
By investing in an npk compound fertilizer granulation production line, fertilizer manufacturers ensure consistent quality, increased crop yields, and strong market competitiveness.
Section 3: Comparing Bentonite Granulation vs NPK Fertilizer Granulation
| Feature | Bentonite Granules Making Machine | NPK Compound Fertilizer Granulation Production Line |
| Primary Material | Bentonite clay | NPK raw powders (urea, phosphate, KCl, etc.) |
| Output Capacity | 1–3 T/H | 8–10 T/H |
| Applications | Agriculture, drilling, foundry, litter | Agriculture (crop nutrition) |
| Technology | Double roller extrusion | Double roller extrusion + multiple equipment |
| Investment | Low (affordable setup) | Higher (large-scale plant) |
| Granule Size | 3–10 mm | 2–6 mm |
Both machines serve unique markets but share a reliance on extrusion granulation technology. For small- to medium-scale production of industrial minerals, the bentonite granules making machine is ideal. For high-capacity fertilizer production, the npk compound fertilizer granulation production line is the right choice.
