Pressure Roller Granulator MKGR-500 500 kg/h with Compacting Rollers – Meelko
The Meelko MKGR-500 pressure roller granulator is an industrial machine designed for the production of granulated material through the roller compaction process. With a production capacity of 500 kilograms per hour and 300 mm diameter compacting rollers driven by an 11 kW motor, this equipment is ideal for manufacturing NPK fertilizers, mineral compounds, granulated chemical products, and various industrial materials that require a uniform granular form for efficient storage, transport, and application.
Pressure Granulation Principle
The MKGR-500 uses the dry granulation principle through compaction, where powder material is forced between two counter-rotating rollers that apply high pressure to form a compacted sheet. This sheet is subsequently crushed and classified to obtain granules of the desired size. Unlike wet granulation methods, this process does not require the addition of binding liquids or subsequent drying stages, which significantly reduces operational costs and energy consumption. The dry granulation process preserves the chemical properties of the original material without alterations from excessive moisture or heat exposure.
300 mm Compacting Rollers
The compacting rollers of the MKGR-500 have a 300 mm diameter and are manufactured from high-hardness alloy steel with specialized surface treatment that resists wear caused by abrasive materials during continuous processing. The roller surface features a texture pattern designed to maximize material grip and ensure uniform compaction across the entire working width. The pressure adjustment system allows operators to regulate the compaction force according to the characteristics of the material being processed, optimizing the density and hardness of the produced granules for each specific application and end-use requirement.
Motor and Transmission System
The 11 kW electric motor provides the necessary power to maintain constant compaction pressure during continuous operation throughout extended production shifts. The transmission system includes a helical gear speed reducer that efficiently transfers torque to the rollers, ensuring synchronized rotation speed between both rollers for uniform compaction. Heavy-duty bearings support the compaction forces without deflection, while the centralized lubrication system keeps all critical points properly lubricated during prolonged operation to extend component life and maintain consistent performance.
Industrial Applications
The MKGR-500 granulator finds application across multiple industrial sectors. In the fertilizer industry, it is used for granulation of NPK formulations, phosphates, potash, and complex blends. In the chemical industry, it processes compounds such as calcium carbonate, magnesium sulfate, potassium chloride, and other powdered chemical products. In the mining industry, it granulates minerals such as activated carbon, benite, and various mineral concentrates. It is also employed in the food industry for granulation of additives, supplements, and nutritional premixes that require a granular form to facilitate accurate dosing.
Classification and Recycling System
The MKGR-500 can be integrated with screening classification systems that separate granules according to their size distribution. Oversized material is crushed and recirculated back into the process, while undersized material is returned to the compaction stage, ensuring maximum material utilization and production with controlled size distribution. This closed-loop configuration maximizes process efficiency and minimizes waste generated during production runs, contributing to lower raw material costs and higher overall yield percentages.
Maintenance and Support
The MKGR-500 maintenance program includes periodic inspection of roller surfaces, verification of the pressure adjustment system, lubrication of bearings and gears, and electrical system review. The rollers are interchangeable and available as original Meelko spare parts through the authorized distribution network. Side access doors allow quick cleaning when changing materials, preventing cross-contamination between different products. Meelko offers complete technical support and advisory services for optimizing granulation parameters according to each client's specific material requirements and production goals.
Safety Features and Quality Control
The MKGR-500 incorporates comprehensive safety features including motor overload protection, emergency stop mechanisms, and protective guards around all moving components to prevent accidental contact during operation. The sealed housing design minimizes dust emissions during processing, contributing to a cleaner and safer working environment that meets industrial workplace safety standards. Built-in sensors monitor roller pressure and temperature in real time, alerting operators to any abnormal conditions that could affect granule quality or equipment integrity. These monitoring capabilities enable consistent quality control throughout production runs, ensuring that every batch of granulated material meets the specified density, size, and uniformity requirements for the intended commercial application.
