Pressure Roller Granulator MKGR-400 at 400 kg/h with Compacting Rollers – Meelko
The Meelko MKGR-400 pressure granulator is a high-capacity industrial machine designed for producing granules through mechanical roller compaction. With a capacity of 400 kilograms per hour, 250mm compacting rollers, and a 7.5kW motor, this granulator transforms powder materials into uniform, high-density granules. It is ideal for manufacturing NPK fertilizers, mineral compounds, granulated chemical products, and raw materials that require dry granulation without liquid binders in the production process.
Technical Specifications of the MKGR-400
This granulator operates with a pair of 250mm diameter compacting rollers that exert controlled pressure on the powder material. The 7.5kW motor provides superior power to maintain constant pressure throughout the entire production cycle at 400 kg/h. The larger diameter rollers compared to the MKGR-300 model allow a wider compression zone, improving the uniformity of the compacted sheet and the final quality of granules produced. The processing capacity adapts to medium-scale production lines with flexibility for different manufacturing volumes.
Pressure Granulation Process
The pressure granulation process of the MKGR-400, also known as dry granulation, directly compresses powder between 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 with liquids. The result is dense, resistant granules with excellent flowability. The additional power of the 7.5kW motor allows processing harder and denser materials compared to lower-power models while maintaining optimal throughput.
Applications of the MKGR-400 Granulator
The MKGR-400 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 with higher production volume. In the chemical industry, it granulates caustic soda, sodium carbonate, magnesium sulfate, and other powder compounds. In the food industry, it processes mineral salts, additives, and nutritional supplements. In the pharmaceutical industry, it granulates excipients and active formulations requiring a moisture-free process.
Advantages Over the MKGR-300 Model
The MKGR-400 offers significant advantages over the 300 kg/h model for growing operations. The production capacity that is 33 percent higher allows fulfilling larger orders in less time. The 250mm rollers provide a more extensive compression zone that improves product uniformity. The 7.5kW motor enables processing denser and harder materials without compromising production speed. These improvements make the MKGR-400 the preferred choice for operations that have outgrown the entry-level model capacity and need to scale up their granule production.
Compacting Roller Design
The 250mm compacting rollers of the MKGR-400 are manufactured from alloy steel with surface hardening heat treatment for extraordinary wear resistance during extended operation. The roller surface can be configured with different texture patterns according to the material being processed. The gap between rollers is adjustable to control the compacted sheet thickness and the final granule size after the crushing and particle size classification stage.
Maintenance and Operation
The MKGR-400 features simplified access to all components requiring periodic maintenance. Rollers are removable for inspection and replacement when necessary. The feeding system includes a variable-speed dosing screw for precise material flow control. 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.
Warranty and Meelko Technical Support
Meelko backs the MKGR-400 granulator with factory warranty, specialized technical assistance, and permanent availability of original replacement parts including rollers, bearings, seals, and transmission components. Our team of engineers provides guidance on optimal equipment configuration. We ship internationally to Latin America, the United States, Europe, Africa, and Asia with logistics options adapted to each destination.
Production Efficiency and Cost Benefits
The MKGR-400 delivers outstanding production efficiency that translates to measurable cost savings for operators. By eliminating the need for water, solvents, drying equipment, and heating systems required by wet granulation methods, the total cost of ownership is significantly reduced. The 400 kg/h throughput capacity ensures that production targets are met consistently, while the dry granulation process produces granules that are immediately ready for packaging or further processing without additional drying or cooling stages. These operational advantages make the MKGR-400 an excellent return on investment for fertilizer producers and chemical manufacturers seeking to optimize their granulation operations.
