Pressure roller granulator MKGR-3000 - 3000 kgh with compacting rollers
Details:
Pressure Granulator MKGR-3000 – 3000 kg/h with 600 mm Compacting Rollers
The pressure granulator MKGR-3000 from Meelko is a high-capacity machine designed for the industrial granulation of NPK fertilizers, minerals, ammonium sulfate, phosphates, potassium chloride and other powdered or fine powder materials that need to be converted into solid, dense and mechanically resistant granules. With a production capacity of 3000 kg per hour, 600 mm diameter compacting rollers and a 45 kW motor, the MKGR-3000 is the ideal solution for medium and large-scale granulation plants.
Dry compaction granulation is a process that requires no liquid binders or subsequent drying stages, significantly reducing operating costs and energy consumption compared to wet granulation methods. The MKGR-3000 leverages this advantage to offer an efficient, clean and economical process that continuously produces high-quality granules.
Operating Principle
The MKGR-3000 operates on the roller compaction principle. The powdered material fed into the machine passes between two steel rollers rotating in opposite directions that exert high pressure on the material, compacting it into a solid sheet. This compacted sheet then passes through a granulation system that breaks and classifies it into granules of the desired size. The resulting fine material is automatically recirculated to the beginning of the process to maximize yield.

Compatible Materials
The MKGR-3000 is compatible with a wide range of powdered or fine powder materials that can be dry compacted and granulated:
- NPK fertilizers and nutrient blends
- Ammonium sulfate and urea
- Diammonium phosphate (DAP) and monoammonium phosphate (MAP)
- Potassium chloride and potassium sulfate
- Calcium carbonate and dolomite
- Magnesium oxide and micronutrients
- Other minerals and inorganic compounds in powder form
Advantages of the Dry Granulation Process
The dry compaction granulation used by the MKGR-3000 offers significant advantages over wet granulation processes:
- No water or binders: the process requires no liquids, eliminating the need for drying stages and reducing product contamination.
- Lower energy consumption: without subsequent drying, total energy consumption is significantly lower.
- High-density granules: compaction produces denser and more resistant granules than those obtained by wet granulation.
- Continuous process: the fines recirculation system guarantees a continuous process without interruptions.
- Low operating cost: fewer process stages mean lower labor and maintenance costs.
Granule Quality
The granules produced by the MKGR-3000 have superior characteristics that make them ideal for direct field application or for use in fertilizer blending lines:
- High bulk density for better application efficiency
- Low friability to withstand transport and storage
- Uniform size for precise dosing
- Low hygroscopicity for better storage under humid conditions
Why Choose Meelko
Meelko designs and manufactures granulation equipment to high quality standards for demanding customers in Latin America, Europe and the world. The MKGR-3000 is the result of years of technical development and customer feedback in the fertilizer and minerals sector.

Installation and Integration
The MKGR-3000 is designed for easy integration into existing production lines. The machine arrives pre-assembled and requires minimal civil works for installation. It can be connected upstream to raw material silos or storage hoppers and downstream to bagging systems, bulk loading stations or blending lines. The compact footprint relative to its production capacity makes it suitable for both greenfield installations and capacity expansions in existing plants.
Control and Automation
The MKGR-3000 features an integrated control panel that allows operators to adjust roller pressure, feed rate and screen selection to optimize granule size and production rate for each specific material. Variable frequency drives on the main motor and feed system allow fine-tuning of the process parameters. Optional PLC-based automation packages are available for plants requiring higher levels of process control and data logging.
