Pressure Roller Granulator MKGR-300 at 300 kg/h with Compacting Rollers – Meelko
The Meelko MKGR-300 pressure granulator is an industrial machine designed for producing granules through mechanical roller compaction. With a capacity of 300 kilograms per hour, this granulator uses 200mm compacting rollers and a 5.5kW motor to transform powder materials into uniform, high-density granules. It is ideal for manufacturing NPK fertilizers, mineral compounds, granulated chemical products, and various raw materials that require a dry granulation process without the need for liquid binders.
Technical Specifications of the MKGR-300
This granulator operates with a pair of 200mm diameter compacting rollers that exert controlled pressure on the powder material, forcing it to pass between the rollers and forming a compacted sheet that is subsequently broken into granules of the desired size. The 5.5kW motor provides the necessary power to maintain constant pressure throughout the entire production cycle. The processing capacity of 300 kg/h adapts to small and medium-scale production lines, offering flexibility for different manufacturing volumes according to market demand.
Pressure Granulation Process
The pressure granulation process employed by the MKGR-300 is also known as dry granulation or roller compaction. Unlike wet granulation methods that require water or binding solutions, this system directly compresses powder between the rollers at high pressure, creating mechanical bonds between particles. This method is especially advantageous for moisture-sensitive materials, hygroscopic products, and formulations that could degrade in the presence of liquids. The result is dense, resistant granules with excellent flowability for subsequent packaging or application.
Applications of the MKGR-300 Granulator
The MKGR-300 finds application across multiple industrial sectors worldwide. In the fertilizer industry, it produces granules of NPK, urea, ammonium sulfate, potassium chloride, superphosphate, and custom blends. In the chemical industry, it granulates products such as caustic soda, sodium carbonate, magnesium sulfate, and other powder compounds. In the food industry, it can process mineral salts, additives, and nutritional supplements. In the pharmaceutical industry, it is used for granulating excipients and active formulations that require a moisture-free process.
Advantages of Dry Granulation
Dry granulation using the MKGR-300 offers significant advantages over other granulation methods. By eliminating the need for water or solvents, the energy consumption associated with subsequent granule drying is drastically reduced. Production times are shorter as no drying and cooling stages are required in the manufacturing process. Investment in auxiliary equipment is lower since dryers, heaters, and air treatment systems are not needed. Additionally, the absence of moisture in the process prevents unwanted chemical reactions between mixture components during the manufacturing process.
Compacting Roller Design
The 200mm compacting rollers of the MKGR-300 are manufactured from alloy steel with surface hardening heat treatment that provides extraordinary wear resistance for extended operation. The roller surface can be configured with different texture patterns according to the type of material being processed, optimizing powder capture and compression. The gap between rollers is adjustable, allowing control of the compacted sheet thickness and consequently the final size of granules produced after the crushing and classification stage.
Maintenance and Operation
Meelko has designed the MKGR-300 with simplified access to all components requiring periodic maintenance. Rollers are removable for inspection and replacement when showing excessive wear patterns. The feeding system includes a variable-speed dosing screw that allows controlling material flow to the rollers. Mechanical protections include a pressure relief system that safeguards the rollers and transmission mechanism against overloads caused by foreign objects or excessively hard material entering the system.
