Pressure Granulator MKGR-800900 with Compacting Rollers
The MKGR-800900 pressure granulator from Meelko is a high-capacity industrial equipment designed for the production of compacted granules through pressure rollers. With a processing capacity of 800 to 900 kilograms per hour and an 18.5 kilowatt motor, this machine is ideal for manufacturing NPK fertilizers, granulated minerals, chemical products and other materials that require densification through mechanical compaction. Its robust design and 400 millimeter compacting roller technology guarantee efficient and uniform production of high-quality granules.
Operating Principle
The pressure granulator operates through the roller compaction principle, where powder or fine granulated material is fed between two counter-rotating rollers that exert high pressure to form a compacted sheet. This sheet is subsequently fractured and classified to obtain granules of the desired size. Unlike drum or disc granulators that require addition of liquid binders, the pressure granulator works dry, eliminating the need for subsequent drying equipment and significantly reducing the energy costs of the production process.
The 400 millimeter diameter compacting rollers are manufactured from special steel with heat treatment that provides exceptional surface hardness to resist compression forces and abrasion from the processed material. The roller surface can be configured with different texture patterns or pockets depending on the type of granule desired, from irregular granules to defined-shape briquettes for specific industrial applications.
Fertilizer Applications
In the fertilizer industry, the MKGR-800900 is widely used for granulating NPK formulations, urea, ammonium sulfate, phosphates, potash and complex nutrient blends. Compaction granulation significantly improves fertilizer handling properties, reducing dust formation during transport and application, improving flowability for mechanized dosing and providing controlled nutrient release in the soil for better crop performance.
The capacity to process 800 to 900 kilograms per hour positions the MKGR-800900 as an ideal solution for medium-scale fertilizer plants seeking to add value to their formulations through granulation. The dry process eliminates problems associated with excessive moisture in fertilizer granules, such as caking during storage and degradation of moisture-sensitive components throughout extended warehousing periods.
Mineral and Industrial Applications
In addition to fertilizers, the granulator efficiently processes mineral materials such as lime, dolomite, bentonite, kaolin, activated carbon, metal oxides and other inorganic compounds that benefit from densification to improve their handling, transportation and dosing capabilities. In the chemical industry, it is used to granulate catalysts, intermediate pharmaceutical products, food additives and special chemical compounds that require a uniform granular form for processing and distribution.
The equipment versatility allows processing materials with different physical characteristics, from fine hygroscopic powders to coarse granulates requiring redensification. The adjustable feeding system allows precise control of the material flow rate to the rollers, optimizing compacted product quality and minimizing recycle material that needs reprocessing in subsequent production cycles.
Classification and Recirculation System
The MKGR-800900 granulator typically integrates with a screening classification system that separates produced granules into three fractions: correctly sized product directed to packaging, oversized material that is crushed and recirculated, and undersized material that returns directly to the granulator feed. This closed classification and recirculation circuit maximizes commercial product yield and minimizes waste from the production process throughout each operational shift.
Motor and Transmission System
The 18.5 kW electric motor provides the force necessary to generate the compaction pressure required by the different materials processed. The industrial helical gear reducer transmission system guarantees efficient and quiet power transfer from the motor to the compacting rollers. Overload protection devices include safety couplings that disconnect the transmission if they detect a jam or excessive pressure, protecting critical equipment components from damage.
Maintenance and Technical Support
The MKGR-800900 design facilitates access to wear components for inspection and replacement. The compacting rollers are removable through a hydraulic extraction system that allows their removal without disassembling other granulator components. Meelko offers specialized technical support that includes assistance in selecting optimal operating parameters for each material, preventive maintenance programs and supply of original spare parts with fast delivery to minimize downtime and maximize production efficiency.
