Pressure roller granulator MKGR-1200 - 1200 kgh with compacting rollers
Details:
The MKGR-1200 pressure granulator from Meelko is a high-performance industrial machine designed for granule production through the roller compaction process. With a processing capacity of 1200 kilograms per hour, this equipment is specifically engineered to meet the demands of large-scale production in fertilizer plants, chemical industries, and mineral processing operations. The 450-millimeter diameter compacting roller system and the powerful 22-kilowatt motor work together to transform powdered materials or fine particles into compact granules of uniform size, high density, and excellent mechanical strength that meet the most demanding standards of the international market.
The operating principle of the MKGR-1200 is based on dry compaction granulation technology, a process that does not require the addition of liquid binders or subsequent drying processes. The powdered material is fed in a controlled manner toward the compression zone between the two main rollers, where extremely high pressure is applied that forces the particles to mechanically bond together forming a continuous compacted sheet. This sheet subsequently passes through a controlled crushing system that reduces it to granules of the desired size, which are then classified through integrated vibrating screens that separate the finished product from material requiring recirculation for reprocessing.
The compacting rollers of the MKGR-1200 are manufactured from high-resistance alloy steel and subjected to a surface hardening process that gives them extraordinary resistance to the abrasive wear generated by the processed materials. The roller surface features a special texture design that optimizes the capture and compression of the fed material, maximizing compaction efficiency and minimizing product slippage. The 450-millimeter diameter provides a wide compression zone that allows reaching the pressures necessary to effectively compact a broad range of materials, from NPK fertilizers to mineral salts and industrial chemical compounds.
The 22-kilowatt electric motor powering the MKGR-1200 granulator has been selected to provide the necessary power to maintain consistent compaction pressure even when processing materials with different compressibility characteristics. The power transmission system uses a high-efficiency helical gear reducer that distributes torque uniformly to both rollers, ensuring symmetrical and uniform material compaction. The motor configuration allows adjustment of roller rotation speed to optimize the process according to the type of material being processed, offering versatility to handle different fertilizer formulations and chemical compounds.
The feeding system of the MKGR-1200 incorporates a variable-speed dosing screw that precisely regulates material flow toward the compression zone. This precise feed control is fundamental to maintaining consistent quality of the produced granule, as variations in material flow can affect the density and uniformity of the compacted sheet. The feeding system design includes a preconditioner that degasses the material before compression, removing trapped air between particles that could weaken the structure of the compacted granule and reduce its mechanical resistance.
The MKGR-1200 frame is constructed from high-strength structural steel and designed to withstand the enormous forces generated during the high-pressure compaction process. The main frame integrates reinforced anchor points that distribute working loads toward the foundation, minimizing vibrations and guaranteeing the operational stability of the equipment. Critical components such as roller bearings are dimensioned with ample safety margins to ensure long service life under continuous working conditions, and the hydraulic pressure adjustment system allows modification of compaction force without stopping equipment operation.
The primary applications of the MKGR-1200 include granulation of NPK compound fertilizers, potassium chloride, ammonium sulfate, urea, and specialized micronutrient blends for the agricultural industry. In the chemical sector, this granulator is equally effective for processing mineral salts, metallic oxides, carbonates, and other compounds that need to be transformed from powder to granular form to facilitate their storage, transport, and precise dosing. The equipment versatility allows operators to adjust operating parameters to produce granules of different sizes and densities according to the specific requirements of each industrial application.
The MKGR-1200 control system includes instrumentation for real-time monitoring of critical granulation process variables, including compaction pressure, roller speed, bearing temperature, and main motor electrical consumption. These parameters are displayed on a centralized control panel that allows the operator to continuously optimize the process and detect early any anomaly that may indicate the need for preventive maintenance. The system also includes automatic overload protections that safely stop operation if abnormal conditions are detected that could damage equipment components.
Maintenance of the MKGR-1200 granulator is designed to be efficient and minimize productive downtime. The compacting rollers are accessible through a quick-opening frame system that facilitates their inspection, cleaning, and eventual replacement when they reach the end of their service life. Lubrication points are centralized and clearly identified to streamline preventive maintenance routines. Meelko provides detailed technical manuals with recommended maintenance schedules and spare parts diagrams that allow maintenance teams to plan and execute necessary interventions in an organized and efficient manner.
The delivery logistics for the MKGR-1200 include international shipping options to destinations in Latin America, North America, Europe, Africa, and Asia. Meelko handles the complete logistics coordination, from industrial equipment packaging to the customs documentation necessary for importation in the destination country. After-sales technical support includes remote assistance for equipment startup and initial calibration, as well as availability of original spare parts with competitive delivery times to ensure customers can keep their production lines running at maximum efficiency with minimal unplanned downtime.
