Pressure Granulator MKGR-5000 – 5000 kg/h with 750 mm Compacting Rollers
The MKGR-5000 pressure granulator by Meelko is a high-capacity industrial machine designed for continuous production of compact, uniform granules. With a processing capacity of 5000 kg/h, 750 mm diameter compacting rollers, and a powerful 75 kW motor, this equipment is the optimal solution for industries requiring large volumes of NPK fertilizers, mineral granules, granulated salt, and other granulated chemical products.
Operating Principle
The pressure granulator operates on the roller compaction principle. Powder or semi-processed material is fed in a controlled manner between two large-diameter rotating rollers that exert high, uniform pressure on the material, compacting it into solid sheets. These sheets are subsequently crushed and sieved to obtain uniformly sized granules. The process does not require water or chemical binders, resulting in a dry, hard granule resistant to transport and storage.
This dry granulation method is particularly valued in the compound NPK fertilizer industry, where preserving the chemical properties of nutrients is essential. Since no heat or liquids are used, nutrients are not degraded at any point during the granulation process.
Technical Specifications of the MKGR-5000
The MKGR-5000 is equipped with special alloy rollers with corrugated or smooth surfaces depending on the material to be processed, mounted on high-capacity bearings to withstand the high compaction forces. The pressure adjustment system allows calibrating compaction force according to the material and desired granule size. The drive is transmitted through high-efficiency reducers that guarantee precise and constant rotation speed.
The feed hopper incorporates a screw feeder that regulates material flow into the compaction zone, ensuring uniform and continuous feeding that is key to obtaining consistently high-quality granules. The integrated screening system separates correctly sized granules from fines and oversized particles, recirculating the latter back to the beginning of the process.
Industrial Applications of the MKGR-5000
The MKGR-5000 pressure granulator is widely used in the following industrial sectors:
NPK and Compound Fertilizers: Granulation of nitrogen, phosphorus, and potassium mixtures to produce controlled-release compound fertilizers. The dry process preserves the exact chemical composition of the NPK formula without risk of unwanted reactions between components.
Minerals and Salts: Granulation of potassium chloride, ammonium sulfate, calcium carbonate, bentonite, silica, and other minerals for industrial and agricultural applications.
Chemical Products: Compaction of raw powder materials to facilitate their transport, storage, and dosing in subsequent industrial processes.
Animal Feed: Production of granulated mineral supplements for cattle, pigs, and poultry.
Advantages of the Dry Granulation Process
Compared to wet granulation or extrusion, pressure granulation with the MKGR-5000 offers the following advantages:
No subsequent drying is required, eliminating the energy cost of dryers and reducing total process time. Granules obtained have higher density and greater mechanical strength than those produced by wet granulation, improving their durability during transport and application. The process is completely dry, facilitating handling of moisture-sensitive materials. The system's flexibility allows quickly changing granule size by adjusting equipment parameters without replacing main components.
Construction and Durability
The MKGR-5000 chassis is built from high-strength structural steel with anticorrosion protection. Parts in contact with material are manufactured from stainless steels or special alloys depending on the type of material being processed. Seals and gaskets are resistant to the most common abrasive and chemically active materials in the fertilizer industry.
The centralized lubrication system ensures proper maintenance of all critical equipment points without frequent stops for manual lubrication, reducing maintenance time and increasing machine availability.
